摘要

摘要:在同种动物、同族动物、不同两栖动物科之间以及两栖动物和非两栖动物之间，已经报道了误导振幅。我们观察到太平洋树蛙和西部蟾蜍之间的误肢，其中树蛙放大了蟾蜍的腿。这些类型的事件可能导致生殖干扰，也被认为是某些物种的进化陷阱。

MISDIRECTED AMPLEXUS BETWEEN A PACIFIC TREEFROG (PSEUDACRIS REGILLA) AND A WESTERN TOAD (ANAXYRUS BOREAS) IN A NORTHERN CALIFORNIA UPLAND

Abstract Misdirected amplexus has been reported between conspecifics, congeners, between different amphibian families, and between amphibians and non-amphibian objects. We observed misdirected amplexus between a Pacific Treefrog and a Western Toad, wherein the treefrog amplexed the toad's leg. These types of events can result in reproductive interference and have also been considered an evolutionary trap for some species.
