Complex causes of amphibian population declines

Article Abstract:

Research is presented in which annual precipitation variation, UV-B exposure and infection by Saprolegnia ferax, a pathogenic oomycete, are studied as possible causes for the declining worldwide population of amphibians. The results show that climate changes have resulted in lower rates of precipitation, which in turn lead to increased exposure to damaging UV-B radiation and, subsequently, increased risk of infection and disease in amphibians.

Climate and amphibian declines

Article Abstract:

Scientists believe that the world's rapidly declining numbers of amphibians may be due to climate changes. Changes in precipation patterns mean less water depth, which exposes amphibian embryos to ultraviolet-B radiation, and this in turn could lead to lethal fungal infection.

Widespread amphibian extinctions from epidemic disease driven by global warming

Article Abstract:

A recent mass extinction associated with pathogen outbreak is tied to global warming. It is described that with the climate change promoting infectious disease and eroding biodiversity, the urgency of reducing greenhouse-gas concentration is undeniable.
