To microbiologists, the term macroecology may conjure iconic images of wildebeests grazing in African savannahs or hummingbirds pollinating flowers in a tropical rain forest. Contrary to what the name implies, macroecology is not the ecological study of macroscopic...

Annually, half of all plant-derived carbon is added to soil where it is microbially respired to CO2. However, understanding of the microbiology of this process is limited because most culture-independent methods cannot link metabolic processes to the organisms...

Dispersal events between habitat patches in a landscape mosaic can structure ecological communities and influence the functioning of agrosystems. Here we investigated whether short-distance dispersal events between vineyard and forest patches shape foliar fungal...
