Changes in host traits help amphibian populations to survive chytrid infection Outbreaks of infectious wildlife diseases often reduce host population size, but rarely cause extinction. An exception is the ongoing global decline of amphibians (1). A pathogenic chytrid fungus, Batrachochytrium dendrobatidis (Bd), may affect amphibian species little to not at all, predictably reduce population size, or have a role in extinction (2). On page 1517 of this issue, Voyles et al. (3) report that at…

Effect of Batrachochytrium Dendrobatidis on Anura Populations Batrachochytrium
Chytrium (Batrachochytrium Dendrobatidis) is a chytrium fungus that causes amphibian chytriomycosis that originated in Africa and spread around the world through trade in animals such as xenopus africanus, and was endemic in Africa for many years before spreadingAround the world.


Shifts in disease dynamics in a tropical amphibian assemblage are not due to pathogen attenuation
The results suggest that host recoveries are not caused by pathogen attenuation and may be due to shifts in host responses, which provide insights into the mechanisms underlying disease transitions, which are increasingly important to understand in an era of emerging infectious diseases and unprecedented global pandemics.
Epidemic disease decimates amphibian abundance, species diversity, and evolutionary history in the highlands of central Panama
A community-level assessment combining long-term field surveys and DNA barcode data describing changes in abundance and evolutionary diversity within the amphibian community of El Copé, Panama, following a disease epidemic and mass-mortality event is presented.

An outbreak of chytridiomycosis in Panama is described and it is argued that this infectious disease has played an important role in amphibian population declines and the high virulence and large number of potential hosts of this emerging infectious disease threaten global amphibian diversity.
Coincident mass extirpation of neotropical amphibians with the emergence of the infectious fungal pathogen Batrachochytrium dendrobatidis
A noninvasive PCR sampling technique is described that can be used to screen museum specimens from other amphibian decline sites around the world and finds evidence of a historical “Bd epidemic wave” that began in Mexico and subsequently spread to Central America.
Population Recovery following Decline in an Endangered Stream-Breeding Frog (Mixophyes fleayi) from Subtropical Australia
This study provides an unambiguous example of population recovery in the presence of Bd, and adult survival was important to overall population persistence in light of low recruitment events, suggesting that longevity may be a key factor in this recovery.
The hypothesis that B. dendrobatidis is a generalist pathogen and that species possessing an innate immunologic defense at the time of disease emergence are more likely to survive is supported.
Complex history of the amphibian-killing chytrid fungus revealed with genome resequencing data
Evidence for selection acting on the Bd genome is reported, supporting the hypothesis that protease genes are important in evolutionary transitions in this group, and it is found that even the most recently evolved Bd clade contained more genetic variation than previously reported.
A Fungal Pathogen of Amphibians, Batrachochytrium dendrobatidis, Attenuates in Pathogenicity with In Vitro Passages
It is hypothesized that the differences in phenotypic performance observed with Atelopus zeteki are rooted in changes of the Bd genome, and future investigations enabled by this study will focus on the underlying mechanisms of Bd pathogenicity.
Riding the Wave: Reconciling the Roles of Disease and Climate Change in Amphibian Declines
We review the evidence for the role of climate change in triggering disease outbreaks of chytridiomycosis, an emerging infectious disease of amphibians. Both climatic anomalies and disease-related
Extinction in Our Times: Global Amphibian Decline
This paper discusses the decline of Amphibian Populations and the Biodiversity Crisis, and the role of Chytrid Fungus as a Cause of Declines and Extinctions.
