Causes of Amphibian Declines A striking feature of amphibian population declines, and what sets them apart from the general biodiversity crisis, is that they have occurred in some of the best-protected natural areas. For example, Sierra Nevada Yellow-legged Frogs have disappeared from wilderness ...
这种真菌名为Batrachochytrium dendrobatidis,属于真菌的壶菌科,是已知的唯一脊椎动物病原体(致病原因)。壶菌的发现被证明是一个转折点,现在疾病,特别是壶菌引起的疾病,已经成为两栖动物数量迅速下降的主要解释。Chytrid真菌目前已在400多种两栖动物中发现,并与北美洲、中美洲和南美洲以及非洲、欧洲、澳大利亚和新西兰的种...

Amphibian populations have suffered widespread declines and extinctions in recent decades. Although climatic changes, increased exposure to ultraviolet-B (UV-B) radiation and increased prevalence of disease have all been implicated at particular localities, the importance of global environmental change remai...
