We report the first case of sexual interaction between two phylogenetically unrelatedspecies (coypu Myocastor coypus and pond slider Trachemys scripta, a freshwater pond turtle),both of them non-native in the study area, a remnant coastal wetland of Tyrrhenian, central Italy(41°57'34.0''N 12°02'58.0''E). We inductively propose two different hypotheses (masturbatory actdue to intense sperm competition, or behaviour induced by female pheromones) to explain thispeculiar observation.

Abstract
We report the first case of sexual interaction between two phylogenetically unrelatedspecies (coypu Myocastor coypus and pond slider Trachemys scripta, a freshwater pond turtle),both of them non-native in the study area, a remnant coastal wetland of Tyrrhenian, central Italy(41°57'34.0''N 12°02'58.0''E). We inductively propose two different hypotheses (masturbatory actdue to intense sperm competition, or behaviour induced by female pheromones) to explain thispeculiar observation.File in questo prodotto:
