It is known that tropical grasslands such as Serengeti host large populations of arbuscular mycorrhizal (AM) fungi and that they respond to abiotic and biotic factors. It is also known that AM symbios
Mutualism improves organismal fitness, but strong dependence on another species can also limit a speciesâ ability to thrive in a new range if its partner is absent. We assembled a large, global data
Mutualisms play a central role in the origin and maintenance of biodiversity. Because many mutualisms have strong demographic effects, interspecific variation in partner quality could have important c
