Description

Abstract. -- The statistical correlation between mammalian species richness and a suite of twelve climatic variables is examined for the state of Texas. The taxa include the total number of native land mammals studied (141 sp.) as well as the number of species of the orders Chiroptera (31 sp.), Rodentia (62 sp.) and Carnivora (29 sp.). At the taxonomic and geographical scales of this analysis, climate is a weak predictor of mammalian species richness. Many of the climatic variables are not orthogonal to each other. The presence of variables that are not mutually orthogonal, introduces multicollinearity into regression models, when these parameters are used as independent variables. It is suggested that these results may be scaling effects. **********
