Zoogeography - 1 EEMB 106 - Zoogeography I. Principles, definitions, processes A. Study of bio/zoogeography 1. Two goals: a. Delineation and characterization of faunal areas b. Determine the evolutionary history of these faunas, in geographical context c. Textbook devoted mostly to descriptive zoogeography 1. terrestrial/freshwater provinces (~ 41% of all known fishes) 2. marine provinces i) epipelagic, surface dwelling species (~ 1%) ii) deep pelagic species (~ 5%) iii) deep benthic species (~ 6%) iv) littoral/continental shelf species (~ 45%) 2. Distribution of taxa in space explained by: a. Historical factors: evolutionary origin of a taxon on one part of planet, subsequent spread of that taxon over evolutionary time. Can explain distribution on regional, continental and global scales. b. Ecological factors: distribution of abiotic (habitat variables: climate, etc.) and biotic (predators, competitors) can explain distribution of organisms: distribution on a local scale. B. Types of distributions
