摘要：

We present a field study to test the hypothesis that intersexuality is a cost of environmental sex determination in Gammarus duebenii. Intersexes are more frequent in a population with a high level of environmental sex determination (ESD) than in a population where few individuals respond to environment cues for sex determination. In a population with a high level of ESD, intersexes are significantly positively correlated with the sex ratio produced under ESD. Intersex frequency is significantly related to the interaction of photoperiod and temperature which the young experience during sex determination.
