BiogeographyBiogeography, Second Edition combines ecological and historical perspectives to show how contemporary environments, earth history, and evolutionary processes have shaped the distributions of species and the patterns of biodiversity. It illustrates general patterns and processes using examples from different groups of plants and animals from diverse habitats and geographic regions. Written primarily for use in undergraduate and graduate courses in plant and/or animal geography, the book serves as a general synthesis and reference as well. |
