Genetic differentiation independent of intertidal gradients in the pulmonate limpet Siphonaria kurracheensis

Abstract

The intertidal limpet Siphonaria kurracheensis (Reeve, 1856) has a bimodal vertical distribution of abundance on rocky shores at Rottnest Island, Western Australia. An electrophoretic study of 5 polymorphic enzymes revealed no consistent genetic differences between adults high and low on the shore. Contrasting with this absence of a detectable genetic response to the steep environmental gradients in the intertidal zone, there were genetic differences among low-shore adults from different sites, and between adults and recruits. This genetic differentiation could be due to either localized selection or temporal variation in the genetic makeup of recruits.
