The Amazon basin harbors a diverse ecological community that has a critical role in the maintenance of the biosphere. Although plant and animal communities have received much attention, basic information is lacking for fungal or prokaryotic communities. This is despite the fact that recent ecological studies have suggested a prominent role for interactions with soil fungi in structuring the diversity and abundance of tropical rainforest trees. In this study, we characterize soil fungal… 

The role of soil chemistry and plant neighbourhoods in structuring fungal communities in three Panamanian rainforests

TLDR
The results show that AM fungal structure is driven primarily by soil chemistry, and for non-AM fungi, soil properties and the local tree community can play a joint role in structuring communities.

Diversity and Structure of Fungal Communities in Neotropical Rainforest Soils: The Effect of Host Recurrence

TLDR
It is demonstrated that vegetation cover has an important effect on the structure of fungal assemblages inhabiting the soil and litter in Amazonian forests, illustrating the relative impact of deterministic processes on fungal community structures in these highly diverse ecosystems.

Relationships Between Fungal and Plant Communities Differ Between Desert and Grassland in a Typical Dryland Region of Northwest China

TLDR
Soil fungal functional communities were assessed based on fungal ITS sequence data, and it was shown that the total, saprotrophic and pathotrophic fungal richness were predominantly determined by plant species richness and/or soil nutrients in the desert, but by MAP or soil CN in the grassland.

Tree communities and soil properties influence fungal community assembly in neotropical forests

The influence exerted by tree communities, topography, and soil chemistry on the assembly of macrofungal communities remains poorly understood, especially in highly diverse tropical forests. Here, we

Late Quaternary climate change explains soil fungal community composition rather than fungal richness in forest ecosystems

TLDR
It is demonstrated that late Quaternary climate change can help to explain current soil fungal community composition and argue that climatic legacies can helpto predict soil funGal responses to climate change.

Non-symbiotic soil microbes are more strongly influenced by altered tree biodiversity than arbuscular mycorrhizal fungi during initial forest establishment.

TLDR
The results indicate that early responses to plant diversity vary considerably across microbial groups, with AM fungal communities potentially requiring longer timescales to respond to changes in host tree diversity.

Endemism and functional convergence across the North American soil mycobiome

TLDR
This work isolates different geographic and local processes hypothesized to shape fungal community composition and activity in pine forests across the continental United States and shows that the principal ecological processes controlling community structure and function operate at different scales.

Variation in forest soil fungal diversity along a latitudinal gradient

TLDR
The results suggest that soil fungal communities are strongly dependent on vegetation type, with fungal diversity displaying an inverse relationship to plant diversity.

Fungal Community Composition in Neotropical Rain Forests: the Influence of Tree Diversity and Precipitation

TLDR
It is suggested that precipitation may be a more important factor than plant diversity or soil nutrient status in structuring tropical forest soil fungal communities.

Towards global patterns in the diversity and community structure of ectomycorrhizal fungi.

TLDR
A global analysis to disentangle the global determinants of diversity and community composition for ectomycorrhizal fungi-microbial symbionts that play key roles in plant nutrition in most temperate and many tropical forest ecosystems provides useful biogeographic and ecological hypotheses for explaining the distribution of fungi.

Phylogenetic similarity and structure of Agaricomycotina communities across a forested landscape

TLDR
The results suggest that environmental heterogeneity strongly influences the phylogenetic β‐diversity of soil inhabiting Agaricomycotina communities, but has only a small influence on forest floor β-diversity, and the strength of community assembly processes, such as habitat filtering, may differ between temperate forest ecosystems.

Potential link between plant and fungal distributions in a dipterocarp rainforest: community and phylogenetic structure of tropical ectomycorrhizal fungi across a plant and soil ecotone.

TLDR
One of the largest molecular studies to date of an ectomycorrhizal community in lowland dipterocarp rainforest demonstrates the potential link between the distribution of tropical tree diversity and the distribution in relation to local-scale edaphic variation.

Taxa-area relationship and neutral dynamics influence the diversity of fungal communities on senesced tree leaves.

TLDR
Although niche dynamics may regulate fungal communities at the habitat scale, the evidence points towards neutral assembly of saprotrophic fungi on individual leaves, with energy availability constraining the taxa-area relationship.

Mycorrhizal fungal diversity determines plant biodiversity, ecosystem variability and productivity

TLDR
It is shown that below-ground diversity of arbuscular mycorrhizal fungi (AMF) is a major factor contributing to the maintenance of plant biodiversity and to ecosystem functioning, and that microbial interactions can drive ecosystem functions such as plant biodiversity, productivity and variability.

Feedback with soil biota contributes to plant rarity and invasiveness in communities

TLDR
The results indicate that plants have different abilities to influence their abundance by changing the structure of their soil communities, and that this is an important regulator of plant community structure.

Diversity and host range of foliar fungal endophytes: are tropical leaves biodiversity hotspots?

TLDR
Molecular sequence data is used to show that endophytes increase in incidence, diversity, and host breadth from arctic to tropical sites, and to elucidate the ecological roles of these little-known symbionts in tropical forests.

Polypore fungal diversity and host density in a moist tropical forest

TLDR
For 10 tree species, fungal incidence and diversity increased with abundance of the host in the community, consistent with across-species density-dependent infection.

Phylogenetic community structure and phylogenetic turnover across space and edaphic gradients in western Amazonian tree communities

TLDR
A role for both broad-scale biogeographic and evolutionary processes, as well as habitat specialization, influencing community structure in Amazonian forests is suggested, suggesting an effect of habitat specialization than dispersal limitation.
