Frogs have layers: a comparative histological study of colour polymorphism in Oophaga poison frogs

Background Colour polymorphism in aposematic species is often associated with ecological divergence and predator selection. In amphibians, colouration is achieved through the chromatophore unit, a layered structure of pigment-containing cells (xanthophores, melanophores) and stru...

Prior infection of harlequin toads by Batrachochytrium dendrobatidis alters their immune-microbial state and increases mortality upon re-infection

Abstract Strategies to improve survival of wildlife impacted by emerging infectious disease are needed for species of conservation concern. We investigated how prior infection by the skin fungal pathogen, Batrachochytrium dendrobatidis (Bd), affected subsequent disease outcomes i...
