- ... Predator induced trait mediated indirect interactions (TMIIs) are likely the dominant facet of trophic interactions in aboveground food-webs. New research is beginning to show that TMIIs are also important in revealing how soil food-webs (SFWs) regulate biogeochemical processes. We suggest that TMIIs can modify SFW functions by (a) regulating the quantity and nutritional quality of plants and anim ...

- ... Protists (=protozoa) are commonly treated as bacterivores that control the bacterial energy channel in soil food webs. This ecologist’s perspective is, however, challenged by taxonomic studies showing that a range of protists feed on fungi, other protists and even nematodes. Recently, it was revealed that obligate and facultative mycophagous protists are common soil inhabitants, while others are f ...
