Causes and conservation strategies of amphibian population declination

Abstract

Abstract: Amphibian populations have dramaticly declined globally over the past decades, including a number of species extinction. Causes of amphibian population declination may include ultraviolet radiation, habitat fragmentation and modification, changes of climate, diseases, invasive alien species and predation, environmental contamination and interactions among these factors. Habitat fragmentation and modification is the main cause. Global change leading to changes of these factors may be the basic reason. More studies on amphibian population should focus on the mechanism responsible for their declination. Some strategies should be put forward to stop this declination process.

Key words: Chongqing, Ecological footprint, Available ecological capacity
