Geographic range size, life history and rates of diversification in Australian mammals

Cardillo, Marcel; Huxtable, J.S.; Bromham, Lindell


What causes species richness to vary among different groups of organisms? Two hypotheses are that large geographical ranges and fast life history either reduce extinction rates or raise speciation rates, elevating a clade's rate of diversification. Here we present a comparative analysis of these hypotheses using data on the phylogenetic relationships, geographical ranges and life history of the terrestrial mammal fauna of Australia. By comparing species richness patterns to null models, we show...[Show more]
