Temperate ectotherms have been predicted to benefit from climate change, but few data yet exist to verify these predictions, and most studies utilize a model of uniform annual temperature increase. In this study, I examine the effects of asymmetric climate warming in temperate ectotherms by subjecting female Uta stansburiana to differing nighttime temperature treatments during their reproductive cycle. I found that higher temperature s during the ovarian cycle increased the proba bility of reproductive success and decreased the duration of the cycle , but did not affect clutch size, egg mass, or relative clutch mass. Higher incubation temperatures increased h atchling size, and decreased the incubation period, but had no effect on incubation success . These findings indicate that higher temperatures during the breeding season could increa se reproductive output and subsequent fitness in temperate ectotherms .
