Unformatted text preview: 11/13/08 2 Two key factors correlated with a community’s species diversity A. geographic location (i.e. latitude) B. size Area Effects Species-area curve Breeding birds in North America Summary (1) - Community Ecology I. Communities may be interdependent (Clements) or independent (Gleason) assemblages of species II. Many interspecific interactions (competition, predation, herbivory, parasitism, mutualism, & commensalism) III. Species Diversity richness vs. relative abundance dominant species, keystone species, ecosystem engineers IV. Trophic Structure Summary (2) - Community Ecology V. Top-down and Bottom-up control mesopredator release hypothesis (cats in SD) VI. Disturbance human, ecological succession (early species facilitate, inhibit, or tolerate succession) VII. Patterns of species diversity A. location (latitudinal gradient) age, climate B. size (species area curves)...
