Abstract
Adaptive radiations can result from ecological processes such as changes in microhabitat availability or topographic complexity that cause shifts in diversification rates. Naesiotus land snails of the Galápagos Islands have undergone such a radiation, with species spread across the archipelago and in many different microhabitats within islands. Though there has been some work to resolve the evolutionary relationships of Galápagos Naesiotus, factors that drive this radiation have yet to be tested in a phylogenetic framework. Examining the relationships between evolutionary patterns and ecological processes can uncover forces driving speciation. Further, in island systems, these relationships often form independently several times, providing a rich data set for comparative analyses. Herein, we employ phylogenetic comparative methods to elucidate some of the ecological factors driving rapid diversification across the archipelago.
