SignificanceClimate change impacts on wildlife populations are likely to be accentuated by pollution. Small (inbred) populations may be more vulnerable to these effects, but empirical data supporting these hypotheses are lacking. We present the first substantial empirical evidence, to our knowledge, for interactive effects on population viability of elevated temperature (climate); an endocrine disrupting chemical, clotrimazole (pollution); and inbreeding. Using the zebrafish (Danio rerio) as a model, we show these three factors interact to skew population sex ratios toward males and that this interaction can lead to increased risk of extinction. Our results suggest that climate change and pollution impacts are likely to pose significant extinction risks for small, endangered populations exhibiting environmental sex determination and/or differentiation.
