Emerging pathogens can drive evolutionary shifts in host life-history traits, yet this process remains poorly documented in vertebrate hosts. Amphibian chytridiomycosis, caused by infection with the fungal pathogen Batrachochytrium dendrobatidis (Bd), is the worst recorded wildlife disease and has caused the extinction of over 100 species across multiple continents. A similar number of additional species have experienced mass declines and Bd remains a major source of mortality in many populations of declined species now persisting with the pathogen. Life-history theory predicts that increased extrinsic mortality in Bd-infected populations may alter amphibian life-history traits, but this has..View full abstract
