项目摘要
Sympatric distribution of closely related species requires some mechanism to avoid the risk of reproductive interference. Distribution and abundance of sympatric Mnais costalis and M. pruinosa damselflies were studied in a low mountain stream in various locations in Japan, from 2011 through 2013. The reproductive seasons of the two species overlapped almost entirely: both species emerged in early May and disappeared in late June each year. Males of both species hold territories within the same stretch of the river; however, two species show some difference in habitat preference leading to the habitat segregation in a way that M. costalis was more abundant on the lower stream, while M. pruinosa was more abundant on the upper stream. We made physiological and ecological studies on various traits which show character displacements (wing-color polymorphism, body size, and habitat preference) and how they are related to habitat segregation and species recognition.
近缘物种的共域分布需要某种机制来避免生殖干扰的风险。2011-2013年间,在日本不同地点的低山溪流中,研究了同域中肋蝇和粉纹夜蛾的分布和丰度。这两个物种的繁殖季节几乎完全重叠:两个物种都在每年5月初出现,并在6月下旬消失。两种雄性在同一河段内占有领地;然而,两种雄性在栖息地偏好上表现出一定的差异,导致了栖息地的分离,在下游有更多的肋骨沼虾,而在上游有更多的粉纹夜蛾。我们对各种性状(翅色多态、体型和栖息地偏好)以及它们与栖息地分离和物种识别的关系进行了生理和生态学研究。
