Gut-retention time in mycophagous mammals: a review and a study of truffle-like fungal spore retention in the swamp wallaby

► Review gut-retention times in ground-dwelling mycophagous (fungus-feeding) mammals. ► Compare fluid and particle retention time across species and groups of species. ► Mean retention time of truffle spores in swamp wallaby, mycophagous macropodoid. ► Studied swamp wallabies carry spores for similar times to smaller mycophagists. ► Potential for long distance dispersal of fungal spores by swamp wallabies.
