Composition of Micro-eukaryotes on the Skin of the Cascades Frog (Rana cascadae) and Patterns of Correlation between Skin Microbes and Batrachochytrium dendrobatidis

open access: yesFrontiers in Microbiology, 2017
Global amphibian decline linked to fungal pathogens has galvanized research on applied amphibian conservation. Skin-associated bacterial communities of amphibians have been shown to mediate fungal skin infections and the development of probiotic ...

Seasonal migrations, body temperature fluctuations, and infection dynamics in adult amphibians [PDF]

open access: yesPeerJ, 2018
Risks of parasitism vary over time, with infection prevalence often fluctuating with seasonal changes in the annual cycle. Identifying the biological mechanisms underlying seasonality in infection can enable better prediction and prevention of future ...

Spillover dynamics and asynchronous temporal fluctuations in host density and competence drive fungal parasite persistence in multi‐host, seasonal communities

open access: yesJournal of Animal Ecology, EarlyView.
In this study, the authors develop a new model to show that species contributions to parasite persistence can have strong, asynchronous temporal variability, often limiting the effectiveness of targeted seasonal parasite control. The model is broadly applicable for partitioning who, when, and what drive parasite persistence in multi‐host seasonal ...

First record of Batrachochytrium dendrobatidis infecting threatenedpopulations of Tandilean Red-belly toad (Melanophryniscus aff.montevidensis) in Argentina

open access: yesRevista Mexicana de Biodiversidad, 2015
We present the first record of Batrachochytrium dendrobatidis (Bd) infecting endangered populations of the Tandilean Red-belly toad(Melanophryniscus aff. montevidensis). We obtained skin swab samples of 32 individuals.

Frogs vs fungus: the emergence of amphibian chytridiomycosis [PDF]

open access: yesMicrobiology Australia, 2022
By the late 1980s, widespread dramatic declines in amphibian populations were causing alarm. The culprit was identified as Batrachochytrium dendrobatidis (Bd), a chytrid fungus that infects the skin of various amphibian hosts, particularly anurans (frogs)

A molecular perspective: biology of the emerging pathogen Batrachochytrium dendrobatidis [PDF]

open access: yesDiseases of Aquatic Organisms, 2009
Ten years after the first discovery of the chytrid pathogen Batrachochytrium dendrobatidis (Bd), the catastrophic effect of Bd on wild amphibian populations is indisputable. However, a number of persistent questions remain about Bd's origin and mechanisms of pathogenicity.

Effects of Timing of Microbial Exposure on Microbiome Assembly and Amphibian Immune Development

open access: yesEcology and Evolution, Volume 16, Issue 8, August 2026.
We used a novel amphibian gnotobiotic system to investigate how disruptions to the microbiome during critical developmental periods influence microbial assembly and the development of immunity. We found that antimicrobial treatments of embryos and subsequent introduction to microbes at different developmental stages altered microbiome assembly ...

Environment and Host Genetics Drive Infection Outcomes in a Butterfly Host, but Do Not Interact With Each Other

open access: yesEcology and Evolution, Volume 16, Issue 8, August 2026.
This study examined how host genetics and larval food plant environment influence parasite infection outcomes in monarch butterflies (Danaus plexippus) infected with the protozoan Ophryocystis elektroscirrha. We tested for genotype × environment interactions on infection status, infection burden, lifespan, and wing size.

Exploring the Role of Prey Availability as a Driver of Seasonal Shifts in Local Distribution of Vipers (Trimeresurus spp)

open access: yesEcology and Evolution, Volume 16, Issue 7, July 2026.
We investigated how seasonal shifts in precipitation and prey availability affect the distribution of arboreal pit vipers (Trimeresurus spp.) in northern Thailand. Trimeresurus were confined to streamside habitats during the dry season but expanded into hillsides during the wet season, mirroring amphibian movements.

Body length of Hylodes cf. ornatus and Lithobates catesbeianus tadpoles, depigmentation of mouthparts, and presence of Batrachochytrium dendrobatidis are related Tamanho do corpo, despigmentação das partes bucais e presença de Batrachochytrium dendrobatidis estão relacionados em Hylodes cf. ornatus e Lithobates catesbeianus

open access: yesBrazilian Journal of Biology, 2013
A fungal pathogen Batrachochytrium dendrobatidis (Bd), which can cause morbidity and death of anurans, has affected amphibian populations on a worldwide basis.
