Co-Exposure with the Herbicide 2,4-D Does Not Exacerbate Batrachochytrium salamandrivorans Infection in the Italian Crested Newt (Triturus carnifex) [PDF]

Animals
Amphibians face a multitude of threats and therefore make a prime example of the current biodiversity crisis. Multiple amphibian stressors in anthropogenic landscapes include infectious diseases and agrochemicals. Synergic effects between these stressors

Differential Susceptibility May Not Drive Chytridiomycosis Related Declines in Multi-Host Amphibian Communities. [PDF]

Ecol Evol
We investigated how Batrachochytrium dendrobatidis (Bd) affects multi‐host amphibian communities in Tasmania, Australia. Despite differential susceptibility, we found no evidence of population declines in susceptible species, suggesting that current environmental conditions may buffer communities against Bd impacts.

Amphibian infection tolerance to chytridiomycosis. [PDF]

Philos Trans R Soc Lond B Biol Sci, 2023
Animal defences against infection involve two distinct but complementary mechanisms: tolerance and resistance. Tolerance measures the animal's ability to limit detrimental effects from a given infection, whereas resistance is the ability to limit the intensity of that infection.

Evolution of research on global amphibian declines. [PDF]

Conserv Biol
Abstract In the late 1980s, the scientific community became aware of severe, enigmatic amphibian population declines. These declines triggered a wave of research focused on quantifying their extent and identifying key drivers. We used text‐analysis techniques, including topic modeling and geoparsing, to examine the evolution of research focused on ...

Amphibian chytridiomycosis [PDF]

Diseases of Aquatic Organisms, 2010
Amphibian chytridiomycosis is a fungal disease caused by the chytrid fungus Batrachochytrium dendrobatidis. It is arguably the most significant recorded infectious disease of any vertebrate class. The disease is reducing amphibian biodiversity across most continents and regions of the world, affecting the resilience of surviving populations and driving

Pathophysiology in mountain yellow-legged frogs (Rana muscosa) during a chytridiomycosis outbreak. [PDF]

PLoS ONE, 2012
The disease chytridiomycosis is responsible for declines and extirpations of amphibians worldwide. Chytridiomycosis is caused by a fungal pathogen (Batrachochytrium dendrobatidis) that infects amphibian skin. Although we have a basic understanding of the

Cool temperatures reduce antifungal activity of symbiotic bacteria of threatened amphibians--implications for disease management and patterns of decline. [PDF]

PLoS ONE, 2014
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.

The amphibian complement system and chytridiomycosis [PDF]

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, 2020
AbstractUnderstanding host immune function and ecoimmunology is increasingly important at a time when emerging infectious diseases (EIDs) threaten wildlife. One EID that has emerged and spread widely in recent years is chytridiomycosis, caused by the fungal pathogen Batrachochytrium dendrobatidis (Bd), which is implicated unprecedented amphibian ...

Response to comment on 'Amphibian fungal panzootic causes catastrophic and ongoing loss of biodiversity' [PDF]

Lambert et al. question our retrospective and holistic epidemiological assessment of the role of chytridiomycosis in amphibian declines. Their alternative assessment is narrow and provides an incomplete evaluation of evidence.

Novel findings on the impact of chytridiomycosis on the cardiac function of anurans: sensitive vs. tolerant species [PDF]

PeerJ, 2018
Background Understanding of the physiological effects of chytridiomycosis is crucial to worldwide amphibian conservation. Therefore, we analyzed the cardiac function of two anuran species (Xenopus laevis and Physalaemus albonotatus) with different ...
