Abstract

A first insight into the transatlantic population genetic structure of the beach flea, Platorchestia platensis (Krøyer, 1845).

Abstract

Platorchestia platensis (Krøyer, 1845) is a cosmopolitan and cryptogenic semiterrestrial amphipod species inhabiting marine coasts all over the temperate and tropical regions of the world. Very little is known about its dispersal mechanisms, and there is little data on the genetic relatedness among local populations in various regions of the world. In this study, we provide first and preliminary molecular evidence that suggests conspecificity of P. platensis populations inhabiting European and North American marine coasts and potentially some genetic isolation of Mediterranean populations.
