Terrestrial vertebrates like amphibians, birds, mammals, and reptiles have different factors influencing their species richness globally. A study found that precipitation is the main predictor of species richness overall, but temperature plays a bigger role in areas with both cold and warm conditions. In the Indomalayan realm, elevation range is crucial. Mammals, birds, and amphibians are more affected by precipitation, while reptiles are more influenced by temperature. This shows that understanding biodiversity requires looking at more than just climate, like elevation, to get a complete picture of how the environment affects different types of animals.
