   “If one has sound data for microbial biomass dynamics in decaying litter, along with identities of the decomposer fungi, then one can make useful projections and hypotheses regarding nutrient flow, environmental controls on decay rates, and potential detritivore production founded upon basic knowledge of the properties of fungal species and their interactions with other microbes and animals[…].”

   “Fish are represented at several trophic levels in aquatic systems, from detritivore and herbivore to carnivore.”
