How does species richness vary with latitude
WebThe islands vary in almost all relevant environmental variables: size, degree of isolation, geological history, climate, topography and bedrock type. The almost thousand-fold variation in island area is accompanied by a 40-fold difference in vascular species richness. The islands differ widely in degree of Pleistocene glaciation. WebJun 20, 2024 · Identifying indicator taxa is a solution to the problem of a lack of diverse data. However, the variation between studies on richness correlations (RCs) among taxa from different climate regions makes the application value of indicator taxa questionable. Few studies have compared the RCs among climatic regions in a single study, leaving the …
