Climate stability drives multidimensional nestedness of amphibian assemblages in a Chinese sky island system

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The nested subset pattern (nestedness) has been widely used to explain species distributions in island and fragmented systems. Mountain sky islands serve as critical natural laboratories for understanding the evolutionary consequences of geographic isolation and climate
