Island Biogeography Of Small Mammals And Associated Ectoparasites In The Ozark Glades, Emily M. Beasley

MSU Graduate Theses

Island Biogeography Theory (IBT) explains and quantifies broad-scale ecological patterns among islands and isolated habitat patches. IBT predicts that the number of species per habitat patch varies as a function of area and isolation as a result of local colonization and extinction. IBT has been extended to habitat islands and hosts as islands for their associated parasites. In the latter system, host body mass acts as a substitute for island area, whereas host population density is used as a measure of isolation. Using the fragmented Ozark glades and the small mammals therein as a model system, I 1) used a …
