host-specific thermal profiles affect fitness of a widespread pathogen.host behavior can interact with environmental context to influence outcomes of pathogen exposure and the impact of disease on species and populations. determining whether the thermal behaviors of individual species influence susceptibility to disease can help enhance our ability to explain and predict how and when disease outbreaks are likely to occur. the widespread disease chytridiomycosis (caused by the fungal pathogen batrachochytrium dendrobatidis, bd) often has species-specific impacts on ...201425505533
cool temperatures reduce antifungal activity of symbiotic bacteria of threatened amphibians--implications for disease management and patterns of decline.chytridiomycosis, caused by the fungus batrachochytrium dendrobatidis (bd), is a widespread disease of amphibians responsible for population declines and extinctions. some bacteria from amphibians' skins produce antimicrobial substances active against bd. supplementing populations of these cutaneous antifungal bacteria might help manage chytridiomycosis in wild amphibians. however, the activity of protective bacteria may depend upon environmental conditions. biocontrol of bd in nature thus requi ...201424941262
Short-term exposure to warm microhabitats could explain amphibian persistence with Batrachochytrium dendrobatidis.Environmental conditions can alter the outcomes of symbiotic interactions. Many amphibian species have declined due to chytridiomycosis, caused by the pathogenic fungus Batrachochytrium dendrobatidis (Bd), but many others persist despite high Bd infection prevalence. This indicates that Bd's virulence is lower, or it may even be a commensal, in some hosts. In the Australian Wet Tropics, chytridiomycosis extirpated Litoria nannotis from high-elevation rain forests in the early 1990 s. Although th ...201122028834
behaviour of australian rainforest stream frogs may affect the transmission of chytridiomycosis.the amphibian disease chytridiomycosis, caused by the pathogen batrachochytrium dendrobatidis, has been implicated in mass mortalities, population declines and extinctions of amphibians around the world. in almost all cases, amphibian species that have disappeared or declined due to chytridiomycosis coexist with non-declining species. one reason why some species decline from chytridiomycosis and others do not may be interspecific differences in behaviour. host behaviour could either facilitate o ...200717933392
environmental refuge from disease-driven amphibian extinction.species that are tolerant of broad environmental gradients may be less vulnerable to epizootic outbreaks of disease. chytridriomycosis, caused by the fungus batrachochytrium dendrobatidis, has been linked to extirpations and extinctions of amphibian species in many regions. the pathogen thrives in cool, moist environments, and high amphibian mortality rates have commonly occurred during chytridiomycosis outbreaks in amphibian populations in high-elevation tropical rainforests. in australia sever ...201121902719
