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.
Ecological Aspects of Amphibian Metamorphosis
It is proposed that as development proceeds, variation in exponential growth coefficients causes a trend from a normal distribution to a skewed distribution of body sizes, and the relation between the ecological model and the physiological mechanisms that initiate metamorphosis can only be suggested.
Global amphibian declines: sorting the hypotheses
More studies are needed to connect the suspected mechanisms underlying both classes of hypotheses with quantitative changes in amphibian population sizes and species numbers, and to identify the hypotheses and conditions under which the various causes operate alone or together.
Isolation of a lethal virus from the endangered tiger salamander Ambystoma tigrinum stebbinsi
This virus, believed to be an iridovirus based on viral morphology and host pathology, was demonstrated to be the primary pathogen in these epizootics, and is the first lethalEpizootic virus reported from salamanders.
Site occupancy models in the analysis of environmental DNA presence/absence surveys: a case study of an emerging amphibian pathogen
The analyses demonstrate the benefits of site occupancy models as a simple and powerful tool to estimate detection and site occupancy (species prevalence) probabilities despite imperfect detection.
The Novel and Endemic Pathogen Hypotheses: Competing Explanations for the Origin of Emerging Infectious Diseases of Wildlife
Current evidence suggests chytridiomycosis may be a novel pathogen being spread worldwide by carriers; until the authors know how much genetic variation to expect in an endemic strain, however, it cannot yet conclude that B. dendrobatidis is a novel Pathogen.
Amphibian Conservation Action Plan
The Species Survival Commission (SSC) is the largest of IUCN's six volunteer commissions with a global membership of 8,000 experts, and is dedicated to securing a future for biodiversity.
INTRASPECIFIC RESERVOIRS: COMPLEX LIFE HISTORY AND THE PERSISTENCE OF A LETHAL RANAVIRUS
It is suggested that larval epidemics amplify virus prevalence and sublethally infected metamorphs (re)introduce the virus into uninfected larval populations, and intraspecific reservoirs may explain the persistence of parasites in and declines of small, isolated amphibian populations.
