The Amazon basin ranges from the Andes to the Atlantic Ocean. It is one of the most diverse biomes in the world and encompasses a series of ecosystems and vegetation types. The Amazon coastline is influenced by the Amazon River and its drainage basin, hosting about 85% of the mangroves and 35% of the sandy coastal plains (‘restingas’) of Brazil. Mangroves and restingas thrive under several limiting environmental factors and provide many ecosystem services, including recreation and tourism, soil protection, carbon sequestration, and nutrient cycling. They are also home to indigenous communities that have a deep connection with them. As these coastal ecosystems develop under unique environmental conditions, they are critically fragile and sensitive to human disturbances. The aim of this project is to identify the molecular diversity of the fungal community and its potential functional role in mangroves and restingas from Northeast Amazon. We also aim to identify indicator species or functional groups associated with their specific soil conditions, to support conservation and rehabilitation projects. The analysis of fungal diversity will allow us to understand the aspects that contribute to mangrove and restinga maintenance, tolerance, and even their resilience in the face of emerging environmental changes.

This research seeks to redress the limited consideration that fungi have received in Nepal's research and conservation priorities, especially within the broader context of the Hindu-Kush Himalayan region. It aims to investigate mycorrhizal fungal diversity and composition in the Eastern Himalayan subalpine conifer forests of Sagarmatha National Park, known as the realm of Mount Everest (8848m). By examining three elevation levels (3000m, 3400m, and 3800m) and two land use types (natural forests and meadows), the study seeks to understand how mycorrhizal communities vary across different altitudes and land use patterns. To achieve this, the project will adhere to the SPUN sample collection guidelines and employ advanced molecular techniques, such as metabarcoding of the rDNA region. 

A significant aspect of this study is its emphasis on community involvement in the research process. The research findings will be shared through peer-reviewed scientific publications and outreach mediums. Moreover, the project aspires to contribute to educational materials, including to update brochures for Sagarmatha National Park and the national checklist of fungi in Nepal. Furthermore, by enhancing our understanding of mycorrhizal diversity, this research aims to highlight the vital role these fungi play in the Himalayan ecosystem and advocate for their preservation through conservation actions.

Rising temperatures in tundra drive heightened wildfire activity, profoundly affecting fungal communities. Recent research highlights the significant influence fungi have on ecosystem carbon balance in northern ecosystems. Fungi impact primary production through plant nutrient acquisition, soil organic matter formation, and C losses via priming. Understanding post-fire shifts in fungal diversity is crucial for predicting wildfire consequences and climate feedbacks. The Yukon-Kuskokwim Delta in Alaska remains relatively understudied. By analyzing fungal diversity across unburned, recently burned, and historically burned sites, we can assess the effects of fire on fungal communities. Initial findings suggest that shrub abundance increases in the first decade following fire, potentially favoring ectomycorrhizal and ericoid mycorrhizal fungi as host plants respond positively to low-intensity burning with strong impacts on soil carbon accumulation and cycling rates. Building on an ongoing investigation of wildfire impacts on components of ecosystem carbon balance, including fluxes of greenhouse gasses and carbon stored in plant biomass and soils, this study will reveal fungal taxonomic identities that may be important regulators of these ecosystem dynamics. Our study will provide new insights into the connections between fungal identities and biogeochemical processing in a critical yet understudied tundra region and support training opportunities for undergraduate students.

The Chilean Matorral has a high degree of plant endemism and a high vulnerability due to anthropogenic pressures, mainly anthropogenic fires, which is why it is currently recognized as a biodiversity hotspot. There is evidence that fire can reduce the richness and abundance of microorganisms in the soil, including mycorrhizal fungi, thus modifying their diversity. On the other hand, there is evidence that after a fire it is possible to find trees that survive and are able to resprout, so they function as nurse plants and can in turn be a source of mycorrhizal fungi for a potential recovery of the affected system. That said, in this study we aim to test the effect of fire and nurse plants on the diversity of arbuscular mycorrhizal fungi in the sclerophyllous forest. This forest is the most representative vegetation formation of the Chilean Matorral and the dominant plant species present there form arbuscular mycorrhiza. A lower diversity of arbuscular mycorrhizal fungi is expected in sites affected by fires and without the presence of nurse plants compared to sites not affected by fires and with the presence of resprouting nurse plants. This project includes work with local communities in order to transfer knowledge among all participants.

Across terrestrial plant species, symbiotic relationships between fungi and roots is common. Various mycorrhizal types prevail in distinct biomes, with arbuscular mycorrhizae colonization contingent upon evolutionary and ecological constraints. Peru boasts a wealth of endemic flora and fauna, nestled within the globally recognized biodiversity hotspot of the "Tropical Andes." Within the Peruvian Andes lie the Puna grasslands and montane forests, constituting the Puna-timberline ecotone, which serve as habitats for endemic plant and animal species and harbor hidden underground biodiversity. Our SPUN project aims to highlight these regions as potential biodiversity hotspots for mycorrhizal fungi while recognizing them as some of the most uncharted territories for soil fungi research. We anticipate observing distinct fungal communities, particularly ectomycorrhizal, with a marked diversity turnover pattern across the three ecosystems: forests, ecotones, and grasslands.

Our project aims at sampling the fungal and mycorrhizal diversity in the foothills of the Andes in Argentina, where dry and shrubby vegetation occur – the Monte. With our team, including landscape ecologists, mycorrhizal experts, and students, we will target patches of Monte from Mendoza to the North of Argentina. Interestingly, these patches surround the viticultural regions of Argentina, and start to be considered as a major niche for biodiversity at a landscape level, becoming a pillar of sustainable agriculture. The Monte is also a habitat where many medicinal plants occur, and where local communities already care for plants and soils. We will discuss the sampling and results with local communities and winemakers to reinforce soil conservation, in the Monte and their landscape, and learn more about the high diversity of AMF already observed from our preliminary results. We expect to find a higher diversity closer to the Andes, where landscapes are more continuous. We also expect to learn about the traditional relationship to soil conservation in the Andes, and its potential impact on fungal diversity. This project will add crucial data to maps of fungal diversity in Argentina, targeting the driest habitats where underground fungi have so far never been explored.

Discerning how climate drives the composition of Arbuscular Mycorrhizal Fungi is essential in mountains where change in elevation corresponds with prominent abiotic shifts across relatively small spatial scales. From low to high elevations, conditions become cooler and drier (mean temperature and precipitation decreases) which can drive the distribution of AMF in soil and how they associate with host plants. To better grasp the ecological role of AMF in different abiotic contexts, we also need to understand how AMF associate with host plants across abiotic gradients. This study will uncover the drivers of AMF diversity and composition across an elevation gradient in the South Western Ghats, part of a global biodiversity hotspot with high diversity and endemism of plant species. We will document AMF in the soil and record root-associated AMF for six tree species—two with wide elevation range and two each restricted to higher and lower elevations. This data will offer the first documentation of mycorrhizal diversity for this region and pave the way for in-depth assessments of how plant-fungal interactions will respond to global environmental change.

Despite extensive ECM and AMF sampling across North America, unsampled ecoregions persist, especially the coastal regions along the Atlantic, Pacific and Arctic oceans. One of the unique landforms that comprise these under sampled coastal ecoregions particularly in the Eastern U.S. are barrier islands, which support coastal dune plant communities. Despite many U.S. barrier islands containing federally protected public lands, these islands have experienced significant coastal erosion because of sea level rise and storm surge. As such, the plant and mycorrhizal communities they support are quite vulnerable. In addition to abiotic factors that are threatening these mycorrhizal communities, chytrid fungi may also pose real threats to mycorrhizal networks, particularly in poorly drained plant communities common across the Mid-Atlantic Coastal Plain ecoregion. Our project aims to uncover the diversity of AMF communities across the eastern U.S. barrier islands and their associated chytrid communities to better understand the contemporary threats mycorrhizal communities face in a wetter, warmer world.

Pampa grasslands originally covered nearly 400,000 square kilometers of fertile plains in Argentina, and today are deeply reduced and threatened by agriculture, fragmentation and invasive plants. Understanding the impact of current activities on the soil biota is crucial for rethinking the management of these grasslands. Our goal is to characterize AMF communities across a gradient of agriculture intensification, spanning from native Pampean grasslands used for extensive husbandry to highly intensified soybean fields. Project outcomes will help design multifunctional landscapes that balance agriculture, conservation and ecosystem services to enhance crop/livestock production while promoting biodiversity.

In Argentina, the Espinal is characterized by the presence of deciduous xerophytic forests that rarely exceed 10 meters in height. Within this ecoregion, the Caldén District is constituted of an open forest where the dominant species is Neltuma caldenia (Burkart) C.E. Hughes & G.P. Lewis (caldén). More than 90 endemic plant species and 50 species of medicinal plants are part of this unique ecosystem in the world. Over the last 150 years, there has been an increase in shrub cover in different areas. Extensive cattle grazing with high pressure, forest fires, tree felling, and climate change are associated with vegetation cover loss, soil erosion, and aridification processes. Different management practices are performed in La Pampa to restore the caldén forests, recover their biodiversity, and their potential as providers of ecosystem services.

The study of arbuscular mycorrhizal fungi diversity will contribute to understanding the ecological role of these microorganisms in the restoration of degraded areas. Additionally, it will allow the establishment of relationships between fungi and caldenal plant species, enhancing the integration of mycotrophic plants and contributing to the development and survival of plant species in these semiarid environments.

Santa Catarina Island, in southern Brazil, is covered with Atlantic Forest and has mangroves and restinga that act as buffers between the ocean and rainforest. The goals of this project are to understand how many taxa of mycorrhizal fungi are shared between the restinga and forest and to investigate the presence of mycorrhizae in the mangroves. Several woody species grow in the harsh conditions of the restinga, and a few of these also grow in the adjacent forest. These plants often have different habits, such as shrubs in the restinga and tall trees in the forest. Mangroves have their own distinct flora with species that are mostly restricted to this environment. We propose two hypotheses: 1) the community of ectomycorrhizal fungi in the restinga soil is similar to that in the forest; and 2) the diversity of ectomycorrhizal fungi in the mangroves is low. The mangroves and restinga are threatened due to climate change and real estate development. Another problem on the island is the spread of exotic Pinus and Eucalyptus species that were introduced. It is unknown how the local fungi communities are affected by the exotic fungi that were introduced with these plants. Knowing the soil fungal communities will allow us to better understand the effects of the invasive species on native plants and to select potential native taxa to be used in restoration projects.

We will promote events open to the public so local communities and students can be involved. For example, the Rick Foray and EctoSul will include field expeditions and talks that emphasize the importance of fungi in the soil. We will also teach participants how to look for ectomycorrhizal mushrooms and recognize and collect ectomycorrhizae in the field, as well as show them root tips with mycorrhizae using dissecting microscopes.

The Western Ghats of India are of tremendous global importance for biodiversity protection and are areas of significant geological, cultural, and aesthetic worth. It is a mountain range that runs parallel to the western coast of India, stretching approximately 1,600 kilometers (990 miles) from Gujarat in the north to Tamil Nadu and Kerala in the south. The Western Ghats mountain system, which is older than the Himalayas, contains geomorphic features of tremendous importance and distinct biophysical and biological processes. The high mountain forest ecosystems at the site impact the Indian monsoon weather pattern. The site, which moderates the region's tropical climate, is one of the outstanding examples of the world's monsoon system. It also boasts a high level of biological diversity and endemism and is considered one of the world's eight 'hottest hotspots' of biological diversity. The site's woodlands contain some of the best examples of non-equatorial tropical evergreen forests and at least 325 species of globally threatened flora, fauna, bird, amphibians, reptile, and fish. Metabarcoding approaches will enable a comprehensive assessment of the soil fungal communities in the Western Ghats, India, allowing for unraveling the intricate and diverse fungal assemblages in this region. The findings will demonstrate significant associations between soil fungal diversity and environmental variables, highlighting the impact of factors such as altitude, land use practices, and soil characteristics on fungal community composition. This research will contribute to the conservation implications and future directions for protecting the unique fungal diversity of the Western Ghats, aiding in the development of effective conservation strategies for this under-explored region.

My research proposal focuses on investigating the presence and variability of arbuscular mycorrhizal fungi (AMF) within the arid grasslands of Masai, situated in the lowlands of Lake Turkana, Kenya. The area comprises a distinctive ecological zone characterized by vast expanses of open grassy terrain and minimal tree cover. The average temperatures in the region can soar above 30°C (86°F) during the hottest months, with occasional peaks reaching even higher. Rainfall in this arid environment is sparse, often falling below 300mm, resulting in limited vegetation and water resources. The grasslands are inhabited by a range of hardy plant species adapted to arid conditions, and they provide vital grazing grounds for indigenous wildlife, including herbivores and migratory species. The region's unique climate and topography create an environment where mycorrhizal fungi could play a crucial role in supporting plants' health and productivity, making it an intriguing focal point for ecological research.

This study aims to quantitatively assess AMF species, compare their community composition across diverse geographical sites and habitats, evaluate their impact on plant productivity, and identify key factors influencing AMF community distribution. Employing a combination of soil sampling, DNA extraction, PCR, sequencing, statistical analysis, and mapping.

This project focuses on Colombia, which ranks as the second most biodiverse country in the world but remains less explored in terms of underground communities. Colombia’s high biodiversity can be attributed to its unique geographic location and topography. This SPUN expedition explores different ecoregions by collecting soil samples in two sampling transects, ranging from highlands (moorlands, 3,000 m.a.s.l) through mid-altitudes, lowlands, and down to sea level. This expedition will encompass various ecoregions: Páramo, montane forests (bosque andino), llanos (tropical savannas), and the Caribbean coast.

The two distinct transects cover diverse environmental conditions and vegetation types that, with the help of different local communities, will enable us to uncover the fungal biodiversity in Colombia. The expedition faces challenges due to the difficult topography, limited routes, and necessary permissions for accessing some locations. However, overcoming these obstacles could lead to the discovery of novel mycorrhizal species and enhance our understanding of ecology and plant-mycorrhizal interactions.

In general, exploring these ecoregions will provide a more precise and realistic representation of underground resources worldwide. Similarly, at the local level, the expedition will empower local communities, stakeholders, and authorities to understand the significance of their natural resources and initiate initiatives for conservation, monitoring, and restoration

We aim to understand the role that soil fungi and plant-mycorrhiza associations play in the stabilization of treeline in the Colombian Eastern Andes Cordillera. The ability of trees from high Andean forests to “migrate” and track suitable temperatures in a warming world may be limited by the absence of the right soil microorganisms and highly specific plant-mycorrhiza associations at higher elevations. To understand the role that each of these two factors plays in determining and stabilizing treeline, we will visit 10 sites around Bogotá city and, in each of them, collect soil and root samples along 3 transects spanning an altitudinal gradient from the High Andean Forest (~3,000 masl) into the Páramo (~3,400 masl) ecoregion. The high Andean Forest and the Páramo ecoregions are biodiversity hotspots severely threatened by climate change and pressures of multiple human activities such as agriculture, cattle farming, and urban development. These tropical montane ecosystems are also highly important as above- and below-ground carbon stocks and may serve as future “carbon refuges” if adequately preserved (Duque et al. 2021). Thanks to SPUN support, we will unveil if the absence of the right microorganisms in the soil will put the few remnants of the High Andean Forest in Colombia more at risk.

Arbuscular mycorrhizal fungi (AMF) play a vital role in ecosystem restoration and sustainability. These fungi form symbiotic relationships with plants to improve plant growth, protect the plants against root pathogens and environmental stress, and promote ecosystem stability. Therefore, understanding AMF diversity will be very important for land use management practice and conservation, especially in semi-arid regions. This project will focus on determining the diversity of AMF fungi in the semi-arid region of Dodoma, Tanzania, by comparing three sites: a natural forest reserve, a tree plantation, and grazing grassland. The AMF will be identified on 30 samples using the ITS region of the DNA and high-throughput sequencing technique using the Illumina platform. The data obtained from this study will not only provide insight on how different land use influences AMF diversity but also contribute to the conservation and management of these ecosystems, ultimately fostering ecological resilience.

The biogeographical Chocó region of Colombia is considered one of the hotspots of global biodiversity; however, it remains an under-sampled area. It is under high threat from several anthropic actions, such as extraction of timber plants without appropriate management plans, mining and the expansion of agricultural borders. For these reasons, it is necessary to increase knowledge of the area that can be used in strategies for conservation plans and the sustainable use of the resources of this region. Our objective is to study ectomycorrhizal fungi at two locations in the Chocó Department; one in the Tropical Moist and Rain Forest of the Nuquí municipality under the climate influences of the Pacific Ocean, and the other in the Tropical Moist Forest of the Capurganá bay under the climate influences of the Caribbean Sea. At both locations, we will work directly with the local communities and the region’s environmental leaders strengthening advocacy for conservation and understanding of the fungal diversity of this biogeographical zone so that the communities can take ownership of their fungal resources and use them appropriately. Additionally, information will be shared for use in future research on biodiversity, systematics, biogeography, ecological restoration, or even as foundation for the discovery of new species.

To this date, most of the information about ectomycorrhizal (ECM) fungi in Indonesia has been generated from the western part of Wallace (Sumatra, Java, and Borneo). Meanwhile, in the eastern Wallace region (Sulawesi, the Moluccas, Papua), the information is limited. Within the project “Ectomycorrhizal fungal communities in the eastern Wallace line,” our aim is to generate a list of ECM species in Gandang Dewata, West Sulawesi, Indonesia, based on DNA information. The ITS Region and LSU will be used for metabarcoding, and Illumina Sequencing will be the chosen Sequence Platform. Additionally, we will gather more information related to the ecology of these ECM fungi by assessing their hosts and the existing above-ground fruiting bodies (mushrooms). New species, new records, and new collections could be obtained from this project.

Our project aims to investigate the variation and complexity of fungal communities in different geographical locations in Honduras; Wampusirpe, Gracias a Dios; Catacamas, Olancho; Tegucigalpa, Francisco Morazán y La Esperanza, Intibucá.  By collecting 108 samples from four diverse sites, the study will employ 16S rRNA metabarcoding and ITS regions, using the Illumina MiSeq platform, to understand the fungal diversity in tropical rainforests, mountainous terrains, grasslands, and urban landscapes. The research emphasizes the relationship between land-use practices, ecological gradients, and fungal community structure. This in-depth exploration holds significant importance for understanding ecosystem dynamics and will contribute valuable information for strategies in sustainable agriculture, conservation, and land management. Collaboration with indigenous communities, insights into small-scale farming, and alignment with the mission of the Society for the Protection of Underground Networks (SPUN) are integral aspects of this vital ecological research as well as providing valuable data for global conservation initiatives.

In California, the Central Valley region once sprawled with lush grasslands of perennial bunchgrasses and endemic forbs unique to a Mediterranean climate region. However, colonization and subsequent urbanization have significantly altered this precious ecoregion. Sites across the landscape have experienced compounded threats from overgrazing, drought, fire regime change, and particularly intense invasion by European species. Current conservation actions include protecting remaining habitats, improving management, and, if possible, converting land to restored grasslands. This project aids these efforts through the investigation of how the soil microbial community has changed along an invasion gradient. For instance, associations with fungal symbionts could confer competitive advantages or cause diseases in the recipient community that contribute to invasion success. We will learn more about how fungi are participating in landscape change either as a consequence or conduit of grassland invasion.

The project is titled "Study of Underground Mycorrhizal Fungi for Landscape Restoration in the Miombo Highlands of Burundi.”. The project aims to generate high-quality data on the belowground diversity of ectomycorrhizal fungi in miombo forests. Sampling will be conducted precisely in the provinces of Buhunnyuza and Isale. Fieldwork will include various tasks such as collecting soil and root samples and conducting surveys of planters. All of this work will be documented using GoPro cameras. A soil subsample will be utilized for DNA metabarcoding, while another will be used to assess AMF spore density and abundance. Soil subsamples will be stored at -80°C until we begin lab work. Fine root samples will be sampled and preserved in ethanol to document and illustrate ECM dependency ratios. Project outputs will elucidate the links between native trees and the diversity of ECM fungi and will support the efforts of local communities to restore the landscape from these native forest species.

The mountain forests of Mount Cameroon and Bioko belong to the volcanic chain that extends northwards along the border between Cameroon and Nigeria, and south-westwards to the islands of São Tomé, Príncipe, and Annobón, and extends to the heights of the island of Bioko Bioko (Equatorial Guinea). The western slope of Mount Cameroon is probably the most diverse and richest area of the mountain and is the only area in West and Central Africa where there is a pristine gradient vegetation of lowland evergreen tropical forest that starts at sea level, crosses montane forests, mountain meadows and alpine meadows near the summit. This link between ecosystems is the main source of the area's great biological diversity. Six main vegetation types have been identified on the mountain. Lowland rainforest (0-800 m above sea level), sub-mountain forest (800-1600 m above sea level), mountain forest (1600-1800 m above sea level), mountain thicket (1800-2400 m above sea level), mountain meadow (2000-3000 m above sea level), and sub-alpine meadow (3000-4100 m above sea level). The general objective of this project is to determine the diversity of mycorrhizal fungi associated with the diversity of the dominant floristic resources of Mount Cameroon. However, this study focuses on answering questions such as; Do the different forest ecosystems of the montane forests of Mount Cameroon and Bioko have the same types of mycorrhizal fungi? Does the floristic diversity of the soil types of each forest ecosystem determine the types of arbuscular mycorrhizal fungi present? Do anthropogenic activities carried out in this area have an impact on the diversity of arbuscular mycorrhizal fungi? Our commitment to this project also involves local communities. In line with the sustainable development objectives, we will focus on: - Educating local communities about the use of CMAs and their importance in agricultural production through videos and explanations in local languages (SDG - 4 and SDG -2). - Show them the impact of their various anthropogenic activities on the life of soil mycorrhizal fungi, while highlighting their responsibility for biodiversity conservation (SDG -12). - Men and women from local communities will be educated together, without distinction and priority (SDG -5).

High elevation regions are unique in their biodiversity and are among the ones facing the highest rate of climate change. This change is causing many irreversible changes in high elevation ecosystems necessitating the elucidation of unique biodiversity present there.  This project aims to test for the effect of temperature and precipitation on mycorrhizal diversity by using natural climatic gradients in Western Himalaya as proxy for climate. Along with the effect of climate, we will also test how plant diversity and plant traits influence mycorrhizal diversity. To fulfill the project aim, we plan to sample a total of 25 localities in western Himalayan region. These localities will represent a factorial combination of temperature and precipitation. To estimate mycorrhizal diversity, 2.5 kb fragment of rDNA will be sequenced. We will involve local people and researchers from Himalayan region during the project work. We expect to generate at least one scientific publication in a peer-reviewed ecological journal. The outputs of the project will be disseminated to the scientific audience as well as the general public for its maximum impact. All the datasets generated during this project will be open access for everyone to use after publication.

Central Chile is part of a global biodiversity hotspot. This Mediterranean ecosystem includes many endemic sclerophyllous plants. It’s currently threatened since it is the most densely-populated area of the country and an agriculture center. This area has the highest diversity of vascular plants, and is the center of diversity of some genera such as the orchid genus Chloraea. Some Chilean orchid species are critically endangered and urgent actions are needed to ensure their long-term conservation. Chilean orchids are terrestrial and associate with mycorrhizal fungi (usually Rhizoctonia-type) that are key for their germination and their subsequent growth and survival. To establish propagation, conservation and restoration programs of Chilean orchids, a full understanding of the diversity and distribution of their fungal partners is required. In particular, we require an understanding of orchid-fungi specificity, since rare and/or endangered orchids could be restricted by the presence of specific orchid fungi in the soil. In this project, we aim to understand the diversity of mycorrhizal fungi in the soil close to different orchid species found in a latitudinal gradient in Central Chile and to compare this diversity with the fungal species that can be found inside the root system of the plants.

The coastal dune ecosystems of the barrier islands along South Texas bays in the northern Gulf of Mexico provide important ecosystem services such as wildlife habitat and serve as the first line of defense against hurricanes and sea level rise. They represent a unique system as the South Texas estuaries and bays surrounding the barrier islands lie along a gradient of salinity (from 8 ppt to 40 ppt) but are considered at-risk ecosystems as they are also subject to different degrees of natural and anthropogenic degradations including oil pollution. It is an ideal system to study the mycobiome diversity of the ecoregion as it can serve as a space-for-time substitution of environmental change impacts on belowground fungal communities. Our project aims to assess the diversity of mycorrhizal communities (and soil mycobiome) in coastal dune ecosystems of barrier islands and how the environment and any concomitant changes shape these communities. Insights gained from the study can help inform conservation of underground communities and coastal management, and potentially aid in nature-based solutions for conservation and rehabilitation of barrier island habitats.  

The project aims to answer the following questions: (i) how are Arbuscular Mycorrhizal Fungal (AMF) communities structured along native and impacted (degraded) areas of southern Amazon? (ii) AMF inhabit and colonize the Amazon leaf litter? (iii) how AMF communities differ between the soil and the adjacent litter? (iv) what is the degree of loss of diversity and functional groups between pristine and degraded areas - What is the impact of degradation? and (v) which and how soil and litter properties can influence the composition of AMF communities under different conservation conditions? The project represents a pioneering study on environmental sequencing of mycorrhizal fungi in soil and litter in the Amazon. The Amazon harbors one of the largest shares of global biodiversity, especially in plant species that can contribute to a huge diversity of microorganisms in the soil and litter. However, it is the Brazilian biome with the fewest diversity inventories for many groups of fungi, such as AMF, especially in the south portion of Amazon, where no work has been effectively published.

The number of fungal species in Madagascar is unknown. Ralaiveloarisoa (2022) estimated that there might be as many as 84,000 – 140,000 species in Madagascar while less than 1000 species (less than 2%) have been described. Many of these species are already under threat due to slash and burn agriculture and might disappear without knowing them. Thus, metabarcoding of the fungal community would be imperative to increase the knowledge on Malagasy fungi more rapidly than is possible with the traditional methods before their vanish. The aim is to produce DNA barcodes of the whole fungal community within a sample using high-throughput DNA sequencing technology and to understand the distribution and the ecological roles of fungi quicker. The results will allow us to compare the fungal diversity from the humid forests in the center and eastern Madagascar to those present in the dry forest in the South-Western. The data produced during this project will increase the number of sequences present in the public repositories so that they also can be used to evaluate the conservation status of Malagasy species.

The North American Great Plains are composed of vast expanses of shortgrass, mixed, and tallgrass prairies. Each system is dominated by unique plant species, such as Andropogon gerardii and Bouteloua gracilis. Associations with arbuscular mycorrhizal fungi play an essential role in maintaining plant dominance in these systems, but the distribution of AMF across this major carbon sink is not well known. With the increasing frequency and severity of extreme climatic events, such as drought, it is critical to understand how these events alter plant-fungal associations across the Great Plains. Hence, we will leverage a network of recently decommissioned precipitation manipulation experiments to investigate the potential legacy effects of drought on plant and fungal communities. We seek to gain insight into the distribution of dominant AMF genera, along with an understanding of how drought of differing intensities influences long-term fungal community composition. We will partner with local nonprofit organizations to meet with community members, discuss the importance of mycorrhizal fungi in provisioning ecosystem services, and train individuals to investigate the fungal diversity around them.

Argentine Mesopotamia is a region composed of 3 provinces and 3 very different ecoregions: the Espinal Ecoregion; the Southern Cone Mesopotamian Savannah, where the Iberá Wetlands are located, the second largest wetland in the world; and the Upper Paraná Atlantic Forest, where one of the 7 natural wonders of the world, the Iguazú Falls is located, and where 52% of the country's biodiversity is found. Despite the ecological importance of this region, it concentrates more than 75% of the country's afforestation with species introduced more than 80 years ago, with pine and eucalyptus, two exotic species with mycorrhizal associations, being the most cultivated. However, it is not known how many mycorrhizal species have been introduced and how they have affected the native fungi. Therefore, the aim of this project is to analyze the diversity of exotic and native mycorrhizae in order to assess the impact of afforestation on native mycorrhizal diversity and to initiate awareness and mitigation measures.

The alpine treeline in the north-western Himalaya forms a distinct ecological boundary between the upper limit of closed-canopy forests and the alpine vegetation. Trees in this ecotone are highly sensitive to climate change, and soil microbes can help relieve climatic stress for them. Investigating how the soil mycobiome responds to environmental changes, including shifts in temperature and precipitation patterns associated with climate change, can help predict and mitigate the impacts of climate change on soil fertility, carbon storage, and ecosystem stability. In this context, the documentation of the soil mycobiome within the treeline ecotone of climate-sensitive Himalayan landscapes is of utmost importance. In the present project, we will collect baseline data on the soil mycobiome using molecular methods (DNA extraction from soil, its amplification using specific primers, and subsequent data analysis). This will help us gain information with potential use in monitoring and assessing ecosystem functionality and tracking the ecosystem impact of impending global climate change. It can also be used to understand how the diversity, distribution, and functionality of the soil mycobiome itself may be affected by the changing climate. The valuable insights gained from the proposed project can be applied to ecosystem restoration programs.

The Miombo woodlands are tropical seasonal woodlands with extensive distribution in Africa, dominated by plant species belonging to the genera of Brachystegia, Isoberlinia and Julbernardia. The Miombo woodlands are economically important for timber production, firewood collection and provision of non-timber forest products among others. The Miombo woodlands are also significant for nutrient cycling due to their capability of forming symbiotic associations with microbes such as fungi. While microbes such as fungi are imperative for mediating ecosystem functions, the diversity and composition of these microbes in Miombo woodlands are poorly understood due to little or no knowledge availability. Further anthropogenic activities such as deforestation, coupled with global climate change, are threats to forest ecosystems with Miombo woodlands inclusive. Therefore, in our project we will explore soil and root associated fungal diversity and composition through fungal DNA barcoding in Miombo woodlands, integrating sites (unexplored for microbes) in Zambia showing variation in abiotic factors (e.g. climatic conditions and soil nutrient availability). The knowledge from this project will provide a better understanding on the interaction of Miombo woodland species with microbes, thereby contributing to sustainable management of these woodlands.

The project will be carried out in the main biodiverse mountain system of Guatemala, Sierra de las Minas, a particular geological and natural system originated from the encounter of ancient land blocks and tectonic plates. It is still now the natural limit in America of Holartic genera as Abies and Acer but contains many others that are distributed in Central America as well as many Neotropical genera.  The scope of this project is to identify molecularly the mycorrhizal composition of its different forest according to the altitudinal gradient.  And after then, 1. To identify the dominant fungal genera and species, 2. To identify those that could be useful for inoculum in forestry and 3. To determine or confirm the taxonomic identity of many fruit bodies of ectomycorrhizal mushrooms, mainly basidiomycetes in the orders Russulales, Boletales and Cantharellales collected before and during the sampling. This is the first large molecular study that will provide information about fungal diversity in the country.

Tropical dry forests are unique ecosystems that are seldom studied. Currently they are under constant anthropogenic threats, such as deforestation and climate change. However, there is very little information about the mycorrhizal communities from these types of forests, partly because attention has focused largely on the most humid ecosystems. We will base our study on one of the last remnants of this type of forest located in the community of Garachiné, in the province of Darién, Panama. We will collect soil from the area and then apply molecular techniques to identify the mycorrhizae present. Our project is a collaborative effort with colleagues from the University of Panama who are developing botanical studies in the area, which will allow us to relate the mycorrhizal community with the flora typical of this type of ecosystem. Our results will allow us to know the diversity of mycorrhizae in an area never studied, as well as their possible relationships with the species of vascular plants present in the tropical dry forest. The information produced will help us motivate further research and the conservation of this unique Ecosystem.

The Selva Paranaense is home to the entire Atlantic forest of Argentina, one of the largest remaining virgin forests in the world. The Selva Paranaense is home to 52% of Argentina’s biodiversity, with more than 150 species of mammals, 564 species of birds, 260 species of freshwater fish, 116 species of reptiles, 68 species of amphibians, and thousands of species of plants and fungi. Due to the high levels of biological diversity and its many endemic species, it is classified as a global biodiversity hotspot. The Paranaense Forest faces serious threats of deforestation from agricultural expansion and the invasion of introduced and invasive species. In the last 120 years, 95% of the native forest has been lost, severely affecting the region’s flora and fauna. It should be noted that a large number of plant species have not yet been fully classified. The counterpart of the enormous plant diversity remains undiscovered: the arbuscular mycorrhizal fungi. These essential actors of nature have not been studied so far in crucial national and provincial reserves. Thanks to SPUN, we will unveil the underground networks of mycorrhizal fungi in these priceless relics.

Northeast India is situated at the confluence of Indo-Malayan, Indo-Chinese and Indian bio- geographical realms and as a result of this the region harbours rich and diverse culture and high biodiversity and endemism. The region’s vegetation types range from tropical rain forest in the foothills to Alpine meadows and cold deserts which amount to more than one-third of the country's total biodiversity. The region is an important part of the Indo-Myanmar biodiversity hotspot, one of the 12 mega biodiversity hotspots of the world and represents 50 percent of Indian biodiversity. Seven hill states that include Arunachal Pradesh, Manipur, Meghalaya, Mizoram, Nagaland, Sikkim and Tripura in the region are collectively referred to as North Eastern Hill Region (NEHR). It is located between of 21°58' to 29°30'N latitude and 88°58' to 97°30' E longitude and is spread over 1, 83,741 km2 area. Climate of the region varies from tropical to alpine type with a very high range of variation in precipitation. AM fungi are obligate symbionts, their population and diversity may be determined by the plant species present in the given ecosystem. The hilly terrain of NEH interspersed with valleys and plains; the altitude varies from almost sea-level to over 7,000 meters above MSL. The change in elevation and climate allowed vegetation/forests of six major categories viz., tropical, subtropical, temperate, montane, subalpine and alpine. Above ground floristic diversity impacts below ground microbiome especially AMF. Information on the distribution and frequency of occurrence of specific AM fungi in the Indo Myanmar Biosphere of the NEH area is very scarce. Hence, we hypothesize to study the abundance and diversity of AMF across gradients in the Indo Myanmar Biosphere of the NEH in the light of changes in elevation and climatic variations in interactive and intra-active mode with native macroflora and microflora respectively.

Soil biodiversity plays a key role in provision of ecosystem services. Conservation of soil organisms and their inclusion in policy agendas is imperative. The Mt. Kenya forest is a biodiversity hotspot but the diversity of most soil biota is unexplored. Mycorrhizal fungi are a key component of forest ecosystems and they influence different biogeochemical processes. This project will compare the diversity of mycorrhizal fungi in protected and unprotected areas within the Mt. Kenya forest. It will provide an insight on the status of mycorrhizal fungi and contribute to the conservation and monitoring of soil biodiversity.

The area of study is the UNESCO heritage sacred Kaya Kauma and Kaya Chivara forest fragments within the Coastal region of Kenya (38.5° E and 41.5° E lies between 0° and 5° S), at 300m above sea level. The area experiences low and unpredictable rainfall with frequent severe droughts. The area is characterised by a variety of soil types and minerals. The two sacred forest fragments, 10.7 km apart, were once a continuous forest landscape stretch. It is intercepted by farmlands and settlements, rill and deep gulley erosion. The plant communities form association with ecto-mycorrhizal and arbuscular mycorrhizal. Tree planting is a common activity in the region with limited evidence of success. Root symbionts are overlooked in tree establishments, and yet the relationship may range from facultative to obligate.  The integration of mycorrhizal association into the nursery management of seedlings is important for survival and subsequent establishment of tree seedlings. The use of native mycorrhiza may guarantee more success. 

A total of 24 soil samples and ectomycorrhizal fruit bodies will be collected from distinct points. The samples and specimens will be transferred to the laboratory for characterization of both Ecto- and Arbuscular- mycorrhiza species and mineral analysis. Morphological and molecular methods involving DNA extraction and nested PCR amplification, will be used for the identification. A mycorrhizal inoculum potential assessment will be conducted using the Most Probable Number (MPN) method. An awareness creation will be undertaken to explain to the community nursery groups the role of mycorrhiza in ecosystem functions and plant nursery management. A semi-structured questionnaire will be used to evaluate management of seedlings.  The mycorrhizal status of seedlings from four nurseries will be inoculated and planted near the sacred forest degraded landscape. Community members and school children will be selected to participate in laboratory observation of mycorrhizal fungi.

The Himalaya Hindu Kush mountain range is a biodiversity hotspot, yet underexplored for soil fungal diversity. It exhibits broad environmental gradients in elevation as well as geographical and temporal gradients in precipitation. These mountains host many ectomycorrhizal trees like oaks, pines, cedars. These sites will be explored for ectomycorrhizal fungi (EMF) including dry and moist temperate forests in Pakistan. The moist temperate forests are located in Kaghan and Bahrian with the dry temperate forests located in Kalam and Parachinar. The ectomycorrhizal fungi will be identified by amplification of ITS as well as LSU region (SSU, rpb if needed). The soil samples will be analyzed by illumina sequencing. Repeating sampling throughout the year will further determine differences among seasons, specifically in relation to the monsoon which is a key climatic event in the region where 80 % of yearly precipitation falls in 3 months. The contrasting precipitation patterns among the habitats and seasons will identify the driving forces for distribution of EMF taxa in relation to this key environmental parameter. The data obtained will unveil the hidden treasure of below-ground plant root symbiotic fungal taxa.

The International Congress of Armenian Mycologists (ICAM) are conducting a nation-wide survey of soil fungi across the mountainous Republic of Armenia, targeting unique microclimates from humid deciduous mixed forest to semi-desert ecosystems clustered across a small geographic range. The Caucasus region and southwest Asia are listed as highly important regions for fungal conservation (Dahlberg et al., 2010), but anthropogenic threats to the Armenian landscapes continue to increase. While travel to portions of the affected regions remains impossible or impractical, the imposing threat of warfare has created an extreme urgency for biodiversity surveys within adjacent ecosystems. Understanding the identities and distribution of fungi in this region is paramount for plant and fungal conservation, and to contribute to a global understanding of soil fungus biogeography, but few studies have occurred within the Southern Caucasus region and even fewer studies have occurred in Armenia relative to its neighbors. By comparing the species composition of fungi across a stark environmental gradient within the small geographic range of Armenia, this project will provide critical information on how biotic soil conditions impact the distribution of mycorrhizal fungi.

The boreal forests of Mongolia are on the southern edge of the Taiga and form a transition to the forest-steppe biome. The forests are composed of mainly Siberian larch (Larix sibirica), Siberian pine (Pinus sibirica), Scots pine (Pinus sylvestris), Japanese white pine (Betula platyphylla) and Siberian spruce (Picea obovate), and experience extremely low winter temperatures with deep soil freezing, and are strongly limited by precipitation.

There are few published investigations of ectomycorrhizal communities in Mongolian forests, however it is known from investigations in other biomes that some of the tree genera have narrow range ectomycorrhizal taxa. In this project we will investigated the ectomycorrhizal communities in mixed and single species forests of in the Bogd Khan protected area, in Umnudelger, Binder soum, Khentii province, and in the Burkhan Khaldun World Heritage Site. Whereas the Bogd Khan protected area is close to Ulaanbaatar, the Burkhan Khaldun World Heritage Site is a remote pristine area. At these sites, we will collect soils and fine roots, and assess the ectomycorrhizal community in soils using metagenomics. The ectomycorrhizal community on fine roots will be assessed by morphotyping the ectomycorrhizas, and the final identification using DNA sequences. We predict and in these extreme conditions a number of unique ectomycorrhizal taxa will be identified. The project will be carried out at the Mongolian University of Life Sciences, and at the Institute of Forest Ecology at BOKU, Vienna.

Tropical forest ecosystems retain the highest levels of biodiversity, fact that makes them great contributors to Earth’s total biodiversity. Mount Mabu is a mountain located in the north of Mozambique of approximately 1700 meters covering roughly more than 7000 hectares. It is estimated that mount Mabu is the largest medium-altitude rain forest in Africa, encompassing diverse wildlife, unknown to scientists. To date, only the vegetation of the lower slopes in the south-eastern has been described – woodland, forest, and scrub/sedge patches on bare rock, remaining the rest unknown. The mycorrhizal fungi, a very important group of soil microorganisms, are present in many habitats but knowledge regarding their presence in tropical regions is still scarce. Their community structures is diverse between mountains at different altitudes, especially in tropical rainforests, so, it is expected that mount Mabu, as an unexplored forest, could represent a hotspot for many species including soil microorganisms such as the mycorrhizal fungi. To address this, sampling, collaborative efforts and use of molecular methodologies are encouraged. Our project intend to sample and isolate AMF using morphological and molecular techniques and lastly attempt to cultivate it in laboratory.

Plant-fungal interactions, such as mycorrhizal symbiosis, are major determinants of plant biogeographic range size, population dynamics and plant community composition. In tropical forest ecosystems of oceanic islands, native and endemic plant communities tend to be replaced by introduced and invasive plant communities resulting in significant changes in the overstory, understory and forest floor. However, in these regions of the world, the impact of biological invasions on soil fungal biodiversity is poorly documented. In this project, we propose to (1) conduct a molecular inventory of soil fungi in the rainforests of Mo'orea, one of the high islands of French Polynesia and (2) assess the impact of the invasive plants Miconia calvescens and Spathodea campanulata on these fungal communities.

The taxonomic inventory of fungal species will be based on high-throughput sequencing techniques of ribosomal DNA (metabarcoding). It will be conducted on DNA extracted from the soils of the high altitude rainforest called "cloud forest" and in the low altitude mesophilic forest on an experimental site listed as a natural area of ecological and heritage interest (ENIEP of Opunohu). The aim is to evaluate the impact of biotic factors (e.g. presence of invasive plants) and abiotic factors (e.g. level of precipitation) on the composition and richness of soil fungi communities (saprotrophs and mycorrhizal symbiotics).A better knowledge of fungal communities in forest soils and endemic tree roots should inform us on the effects of fungal microbial communities on the vulnerability and resilience of tropical rainforests to plant invasions, in a context of climate change.

The project aims at producing high quality data on the diversity and abondance of soil mycobiome in Cacao plantations of Ivory Coast. Ivory Coast (West African) is the largest cocoa (Theobroma cacao) producer in the world with three production regions (East, Centre-Western, and the South-Western). Cacao plantation are subject to different management regimes, including agroforestry systems in the vicinity of natural dense forests. We hypothesized that plantations under long term management regime (old plantations) have an altered structure of soil mycobiome that has led to a decrease in the diversity of soil fungi. Three different management regimes (+ natural forests) from four sites of the ongoing CacaoSAF project (Alliance Bioversity - CIAT), will be considered. At each of the 14 sampling sites, composite soil cores and fine roots will be sampled from a total of 10 cacao trees and from most dominant tree in the dense forests. Mycorrhizal dependence and AMF spores’ identification and density will be performed at the University of Parakou in Benin. Doubled of soil samples will be shipped to the Swedish Agricultural University for metabarcoding (NGS). Semi-structured interviews will be conducted with the farmers of the CacaoSAF tool project to collect information about the age of the plantation, the management regime, productivity over time and the natural forest. For each sample we will fill the metadata form. At the end of the project, the farmers of the CacaoSAF project can appreciate how their management practices affect soil mycobiome. Partner scientists from the Institute National Polytechnique Félix Houphouët-Boigny will benefit from molecular data and the identification of AMF of the cocoa trees in Ivory Coast. We expect to generate at least one paper in peer-reviewed applied ecological journal or in organisms’ diversity journals. Generated sequence data will be shared with the CacaoSAF tool developed by the Alliance Bioversity-CIAT, as well as on international accessible platforms.

The Amazon Region has a large number of ecosystems, which house a high biotic diversity. It is considered a hotspot for soil fungi and protects a high level of fungal endemism (Tedersoo et al. 2014, 2022). The project intends to study soil fungal communities, including arbuscular mycorrhizae and ectomycorrhizae, at three contrasting and distant points in the Colombian Amazon, which will allow us to learn more about the distribution patterns of soil fungal communities, and in particularly mycorrhizae. In addition to studying white-sand forests and terra firme forests, alluvial plain or várzea forests will be included, which have not yet been studied.

Uruguay is part of the temperate subhumid grasslands in the eastern part of South America. Our territory is described as Campos within Biome Pampa according to physiognomic, geomorphologic, and edaphic features. This region shows year-round photosynthetic activity and represents one of the world's most diverse, largest, and less transformed grassland areas. Despite their apparent physiognomic homogeneity, these grasslands hold high species diversity, having grasses as the dominant life form except for a few scattered shrubs and trees. Actually, Uruguay lost 10% of its pastures.  A regional mapping work of the Pampa biome (Brazil, Argentina, and Uruguay) shows the reduction of the grassland ecosystem over two decades. Our country's main driver of pasture losses was agriculture, followed by forestry and invasive plants.

It is widely recognized the key role of arbuscular mycorrhizal fungi (AMF) in terrestrial ecosystems, as they regulate nutrient and carbon cycles influencing soil structure, plant community, and ecosystem multifunctionality. The role of mycorrhizal symbiosis has been usually related to its impact on the plant mineral nutrition However, it has been demonstrated that this symbiotic process has a key role in ecosystem stability and restauration. AMF is a mutualistic microorganism that links biotic and abiotic components of ecosystems, mediating plant competition and nutrient distribution.  Our question is, within Campos, which factors are driving and modulating AMF biodiversity? Four sites representing conserved grasslands will be sampled; we will combine different approaches to understanding AMF diversity by looking at the links between AMF and plant community structure, geochemistry, and soil microbial community interactions.

Three hypotheses are proposed: (1) AMF diversity is affected by soil type, and physicochemical environmental conditions; (2) AMF diversity responds to changes in above-ground plant community diversity; and (3) AMF diversity is affected by the interactions with soil microbial communities (fungi and bacteria) that coexist in the same site.

During this project, motivation to local communities will be through seminars and talks. Local communities, especially students from rural schools, could keep the plant communities under observation within passive conservation and restoration mini-projects aimed to involve them in a change of mind about soil health and below- and above-ground biodiversity.

The goal of this project is to understand whether non-native invasive plants are able to successfully displace native congeners by interacting with their native obligate symbionts: ectomycorrhizal fungi. The project will take place in the eastern region of Patagonia, Argentina, a steppe ecosystem, dominated by xerophytic herbaceous and shrubby plants. Even when the steppe is the dominant ecosystem in the southern cone of South America, belowground studies in Patagonia drylands are underrepresented compared to Andean temperate forests. We will sample soil under native and non-native invasive riparian populations of Salix spp. (willows). These tree species are the only ectomycorrhizal hosts in this habitat, which constitutes the limit of their southern distribution, where mutualisms are expected to be key for their establishment and survival.  Studying whether invasive plant species can interact with native fungi and the potential changes in the native fungal community driven by invasions, will shed light into previously overlooked belowground impacts of plant invasions in the steppe and open new management possibilities, helping to prevent economic and biodiversity losses. We will actively work with local stakeholders, the private sector, and local and native communities, increasing the awareness of the fungal component of invasions and encouraging them to get involved in the idea that fungi can also be invasive and that we need to protect native funga from degradation.

Nepal is a country with abrupt elevation gradient, ranges from 50 to 8848 meters above sea level, towards the North resulting in contrasting climate and habitat formation. This change in elevation and climate allows diverse habitat formation and floral and faunal diversity vary greatly across the regions. Furthermore, In the East-west gradient, the precipitation patterns greatly vary in the country. In the monsoon season (June-Aug), heavy precipitation occurs in the Eastern regions and the western region receives less rainfall. In the winter season, the Western region receives more rainfall than the Eastern region. However, the total rainfall in the winter season is lesser than monsoon season. This creates a different soil moisture regime in East-West regions. Therefore, elevation and climate gradient towards the North and precipitation gradient towards East-West make Nepal rich in floral and faunal (aboveground) biodiversity hotspots, however, soil (belowground) biodiversity hotspots are yet to be determined. We assume the change in elevation gradient and habitat types altered the soil biodiversity. Soil sampling across elevation, climate, and precipitation gradient will help us to elucidate the diverse soil flora and faunal diversity. We will also have an opportunity to understand and assess the soil biodiversity in higher elevation zones, which is unique to Nepalese landscapes. Currently, we are collecting soil samples (voluntarily) from each of the physiographic areas. We only have three paired sites for this assessment. We followed the Soil Biodiversity Network (SoilBON) protocols to collect, prepare, store, and ship the samples. These sites broadly cover the soil biodiversity status of Nepal but are limited to covering all habitat types towards North-South and East-West regions. Therefore, we would like to extend our sampling sites from 3-paired sites to additional 18-paired sites and the results will contribute directly to the sample pool of SoilBON.

This is an interdisciplinary nationwide project with more than 30 scientists from UNAM (National Autonomous University of Mexico). It is part of the University Program of Interdisciplinary Soil Studies (PUEIS) Developed primarily at the Institute of Biology, Institute of Ecology, Faculty of Sciences, and Faculty of Higher Education of Iztacala.

The soil constitutes the ecological interface that harbors the greatest biodiversity in terrestrial ecosystems. Soil regulates global biogeochemical cycles, supports biological diversity, activity, and productivity, and provides the nutrients necessary for plant growth. A conserved soil is a biodiverse soil maintaining ecological functions such as microbial activity, carbon and nitrogen mineralization, and enzymatic activity. Despite the importance of soil this resource is not renewable, and its conservation is threatened by mismanagement and the lack of effective communication strategies about it. In Mexico, 45% of the territory has degraded soils, which means that they have lost the ability to maintain their ecological function, their biodiversity, and their productivity. Part of the problem is the lack of data and information on biodiversity and soil function in large geographic areas of Mexico to strengthen decision-making aimed at its sustainable management.

The Atlas of Mexico’s Soil Biodiversity have three guiding principles (Research, Teaching and Society Outreach), each with the following objective. Research – To generate frontier knowledge using public biodiversity databases, collaboration networks and the most modern DNA sequencing technologies to produce the greatest possible amount of knowledge in the shortest time and at the lowest cost. Teaching – To generate learning elements for high school, undergraduate and postgraduate levels to promote knowledge of life in Mexican soils and the need to protect this non-renewable resource. Outreach – To create an interface for data display and analysis to provide information to decision makers that promote friendly management practices with soil diversity, as well as programs for its conservation and monitoring.

The idea of our project within SPUN is to provide evidence of root mycobiome biodiversity around monumental trees forming the backbone of East Carpathian Biosphere Reserve. Polish NGOs have provided us with GPS coordinates of 3675 ‘monumental trees’ which should be considered as the ‘hot spots’ of the region, but still are being logged there at an alarming rate.

We intend to support the initiative to include this priceless sites in the Bieszczady National Park. Therefore, we want to share the scientific data with the activist and artistic communities in Poland to speak more loudly about the importance of forest mycorrhizal networks.

Humboldt reported that tropical plant species richness decreased with increasing elevation and decreasing temperature. Tropical regions harbor the majority of the world’s biodiversity, surprisingly, patterns in plant and fungal diversity on tropical mountains have not yet been described. Alexander von Humboldt ascended the Chimborazo, Antisana and Pichincha volcanos in Ecuador. He recorded the distribution of plant species and vegetation zones along its slopes and in surrounding parts of the Andes. We propose to follow the steps of those three Humbold´s expedition, following an Andean transect traversing 3.5 to 5 km in elevation (equivalent to a 6.5°–26.4°C mean annual temperature range) to test whether the soil fungal species, particularity mycorrhiza, diversity and composition follow similar biogeographical patterns with shared environmental drivers. This will be done for the first time in Ecuador. With the help of historical records of Humboldt's Expedition.
