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

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 change, but their species distribution patterns remain poorly understood. Compared to lowland fragmented habitat islands, biodiversity patterns in mountainous regions are more complex, and traditional drivers may not adequately explain the nestedness of sky islands. To uncover the underlying mechanisms of mountain biodiversity, this study sampled amphibians across 30 sky islands in the Dabie Mountains, China, aiming to explore the nestedness of amphibian assemblages and their formative mechanisms from taxonomic, functional, and phylogenetic perspectives. Taxonomic nestedness was quantified by constructing species incidence matrices and calculating nestedness metrics, while functional and phylogenetic nestedness were asse..., , # Data from: Climate stability drives multidimensional nestedness of amphibian assemblages in a Chinese sky island system
