Document Summary
In multiple choice format, identify the definitions to the following terms: Biogeography: study of patterns of species composition and diversity across geographic locations as u go up latititude for north america species diversity goes down. Regional scale: areas with uniform climate; the species are bound by dispersal to that region. Gamma diversity: regional species pool all the species contained within a region. Landscape: topographic (hills mountains) and environmental features (wetlands/lakes): of a region. Alpha diversity: local scale equivalent to a community. species physiology and interactions with other species are important factors in the resulting species diversity. Beta diversity: change in species number and composition, or turnover of species, from one community type to another. Global biogeography: global patterns of species diversity and composition are controlled by geographic area and isolation, evolutionary history, and global climate. Laurasia: cretacious period (100 mya) became north america and asia/europe. Gondwanaland (gondwana): cretacious period (100 mya) -> became sa, africa,
