Global amphibian population declines

Nature, 2001
The decline and disappearance of relatively undisturbed populations of amphibians in several high-altitude regions since the 1970s suggests that they may have suffered a global decline, perhaps with a common cause or causes¹⁻³. Houlahan et al.⁴ examined means of trends for 936 amphibian populations and concluded that global declines began in the late ...

Quantitative evidence for global amphibian population declines

Nature, 2000
Although there is growing concern that amphibian populations are declining globally, much of the supporting evidence is either anecdotal or derived from short-term studies at small geographical scales. This raises questions not only about the difficulty of detecting temporal trends in populations which are notoriously variable, but also about the ...

Amphibian declines: an immunological perspective

Developmental & Comparative Immunology, 1999
Many, but not all, amphibian populations have been declining on all six continents on which they live. Although habitat destruction, direct application of toxicants, and introduction of predators/competitors are obvious causes of amphibian declines, many amphibians are dying of infectious diseases in relatively pristine habitats on several continents ...
