Biogeography is the scientific study of the spatial and temporal patterns of biodiversity, examining how and why the distributions of species, populations, communities, and ecosystems vary across geographical areas and through evolutionary time. It integrates principles from ecology, evolution, geology, and climatology to analyze processes such as dispersal, speciation, extinction, vicariance, and range shifts. Biogeography encompasses subfields including historical biogeography, which reconstructs past distributions using phylogenetic and paleontological data, and ecological biogeography, which investigates how current environmental gradients, habitat structure, and biotic interactions shape present-day distributional patterns and biodiversity gradients, such as latitudinal diversity clines and island faunas.
A new study published in the Proceedings of the National Academy of Sciences reveals that smaller islands within the Wallacea biodiversity hotspot are crucial refuges for endangered vertebrates, providing higher-quality habitats ...
