The Swamp Wallaby 'Wallabia bicolor': a generalist browser as a key mycophagist

Abstract

Mammal-macrofungal interactions are integral to ecosystem function in landscapes dominated by ectomycorrhizal (EM) plants. EM fungi, critical symbiont's with forest plants, produce sporocarps (fruit bodies) which are an important food resource for a variety of mammals. These mammals in turn play an important dispersal role, particularly for truffle-like (below-ground fruiting or hypogeous basidiomycetes) sporocarpic fungi that do not actively discharge their spores (sequestrate). This thesis examines interactions between truffle-like fungi and a non-specialist, mycophagous marsupial, the swamp wallaby 'Wallabia bicolor'. The availability of truffle-like fungi sporocarps as a food resource for mycophagous (fungus-feeding) mammals, the macrofungal diet of the swamp wallaby, and gut-retention and potential dispersal of macrofungal spores by swamp wallaby are examined.
