The online database MaarjAM reveals global and ecosystemic distribution patterns in arbuscular mycorrhizal fungi (Glomeromycota).
A new database, MaarjAM, that summarizes publicly available Glomeromycota DNA sequence data and associated metadata is described to facilitate the description of distribution and richness patterns in this group of fungi.

The findings suggest that partner specificity in AM symbiosis may occur at the level of ecological groups, rather than at the species level, of both plant and fungal partners.

This work redefined the traditional concept of assembly rules in a more general framework where the co‐occurrence of species is a product of chance, historical patterns of speciation and migration, dispersal, abiotic environmental factors, and biotic interactions, with none of these processes being mutually exclusive.
Composition of root‐colonizing arbuscular mycorrhizal fungal communities in different ecosystems around the globe
The current global analysis of AM fungal communities suggests that soil micro-organisms may exhibit different distribution patterns, resulting in a high variability of taxon richness and composition between particular ecosystems.
Global assessment of arbuscular mycorrhizal fungus diversity reveals very low endemism
The wide distribution of plant-root fungal symbionts seems to be driven by recent dispersal rather than ancient tectonics, and it is suggested that the biogeography of AM fungi is driven by unexpectedly efficient dispersal, probably via both abiotic and biotic vectors, including humans.
Fifty thousand years of Arctic vegetation and megafaunal diet
The authors' analyses indicate that both graminoids and forbs would have featured in megafaunal diets, and question the predominance of a Late Quaternary graminoid-dominated Arctic mammoth steppe.
IS SMALL-SCALE SPECIES RICHNESS LIMITED BY SEED AVAILABILITY OR MICROSITE AVAILABILITY?
It was concluded that, though the behavior of individual species may differ, the local deficiency of seeds may be an important force generating small-scale community patterns of calcareous grasslands.
Global sampling of plant roots expands the described molecular diversity of arbuscular mycorrhizal fungi
Ordination revealed differences in AM fungal communities between different continents and climatic zones, suggesting that both biogeographic history and environmental conditions underlie the global variation of those communities.
