Emerging infectious diseases and amphibian population declines.
We review recent research on the pathology, ecology, and biogeography of two emerging infectious wildlife diseases, chytridiomycosis and ranaviral disease, in the context of host-parasite population biology. We examine the role of these diseases in the global decline of amphibian populations and propose hypotheses for the origins and impact of these panzootics. Finally, we discuss emerging infe...
متن کاملEmerging Ranaviral Infectious Diseases and Amphibian Decline
Infectious diseases caused by ranaviruses (RV, family Iridoviridae) not only affect wild amphibian populations but also agriculture and international animal trade. Although, the prevalence of RV infections and die offs has markedly increased over the last decade, it is still unclear whether these viruses are direct causal agents of extinction or rather are the resulting (secondary) consequences...
متن کاملAmphibian Population Declines : Evolutionary Considerations
May 2007 / Vol. 57 No. 5 • BioScience 437 L losses in biodiversity are being documented around the world in almost all classes of plants and animals (Lawton and May 1995). Although the exact number of species being lost is unknown, some researchers estimate that the rate of extinction is greater than any known in the last 100,000 years (Wilson 1992). This biodiversity crisis is exemplified by t...
متن کاملInfectious disease and worldwide declines of amphibian populations, with comments on emerging diseases in coral reef organisms and in humans.
Many populations of amphibians are declining on all six continents on which they occur. Some causes of amphibian declines, such as habitat destruction, direct application of xenobiotics, and introduction of predators or competitors, are clearly attributable to human activities. Infectious disease appears to be the direct cause of mass amphibian die-offs in relatively undisturbed areas of the wo...
