摘要

本文报道了两个系统发育无关的物种(coypu myastor coypus和池塘滑龟Trachemys scripta，一种淡水池塘龟)之间的第一例性互动，这两个物种都是非原产于意大利中部第勒尼安(41°57'34.0 " N 12°02'58.0 " E)残留沿海湿地的物种。我们归纳地提出了两种不同的假设(由于激烈的精子竞争而产生的手淫行为，或由雌性信息素引起的行为)来解释这一奇特的观察结果。

Attempted copulatory behaviour between two phylogenetically unrelated alien species (Coypu, Myocastor coypus, and Pond slider, Trachemys scripta): first evidence

We report the first case of sexual interaction between two phylogenetically unrelated species (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 act due to intense sperm competition, or behaviour induced by female pheromones) to explain this peculiar observation.
