温度对剑尾鱼性逆转的影响

THE EFFECTS ON SEXUAL REVERSION OF XIPHOPHRUS HELLERI BY TEMPERATURE

本文研究了剑尾鱼（Ｘｉｐｈｏｐｈｒｕｓｈｅｌｉｅｒｉ）在体型和性行为方面，雌鱼生殖后在不同温度下转变为雄性的现象．雌剑尾鱼在能生存的温度范围内，都有性逆转现象，但在生存温度的上限和下限内性逆转率较高，其余温度内性逆转率较低，甚至为零．

The phenomenon that femal xiphophrus nelleri can mutate male xiphophrus nelleri in body shape and sexual behavior after reproducing in different temperature conditions was researched in this paper. In survival temperature scope, all of xiphophrus helleri have the capbility of sexual reversing, but the reversing ratio is high in upper limit and floor level, otherwiseis lower, even orrives at zero.
