Parasites of Trinidadian guppies: evidence for sex- and age-specific trait-mediated indirect effects of predators.

abstract：:Evidence accumulates about the role of arbuscular mycorrhizal (AM) fungi in shaping plant communities, but little is known about the factors determining the biomass and coexistence of several types of AM fungi in a plant community. Here, using a consumer-resource framework that treats the relationship between plants a...
