One species exhibiting a large skin microbiome shift in captivity is the variable harlequin frog, Atelopus varius. A soft-release of A. varius to outdoor mesocosms “restored” the microbiome through time, and frogs also increased antifungal function of their skin microbiome with time in mesocosms. Rewilding the microbiome may influence resistance to diseases such as chytridiomycosis.
