TLDR
The overall effect of leaf-eating invertebrates on aquatic hyphomycetes resembles that of potent competitors preempting substrate otherwise used by a late successional tail of relatively rare fungi.Abstract:
Leaf-eating invertebrates selectively ingest leaf areas rich in fungal cells. The effect of this process on coincident and cumulative species diversity (species numbers and evenness) of the fungi was studied on 3 substrates (oak leaves, larch and spruce needles) in 2 hardwater and 2 softwater streams. Cumulative species number of colonizing fungi follows the equation S=k·A
z(A=area below decay curve of the substrate, k=substrate-specific constant, Z=0.47). Higher feeding activity means faster weight loss of the substrate which leads to lower species richness of the fungi. The opposite is true for early successional stages on larch needles. Evenness of the fungi (distribution of individuals among species) is negatively correlated with feeding intensity by invertebrates, as measured by increased decay rates. The overall effect of leaf-eating invertebrates on aquatic hyphomycetes resembles that of potent competitors preempting substrate otherwise used by a late successional tail of relatively rare fungi.read more

Mechanisms of Microarthropod-Microbial Interactions in Soil
TL;DR: This chapter provides an overview of the mechanisms of microarthropod by focusing on the microbial interactions in soil, and examines how dispersal and selective grazing in the rhizosphere affect the distribution and abundance of fungi in soil.

Interactions with invertebrates
TL;DR: Woodland streams receive significant quantities of leaf litter and woody debris from the riparian vegetation, which provides much of the carbon and energy for the detritus-based food chains that are common in streams.

Plant species diversity in a marine intertidal community: importance of herbivore food preference and algal competitive abilities
TL;DR: Predators or herbivores do not simply increase or decrease species diversity of their food, but can potentially do both and the results may apply to most generalized consumers and provide a framework within which previously confusing results can be understood.
