Species Composition and Population Dynamics of Amphibian Species Diversity in Leigongshan, Guizhou

The biodiversity and population dynamics of amphibians are the basis of amphibians conservation. During the period of 2014-2018, amphibian species composition and population dynamics in Leigongshan National Reserve of Guizhou Province were investigated by using the transect sampling method.
