Exposure to warmer water can greatly increase the reproductive powers of the common pest fish gambusia, a new study shows. Male gambusia exposed to higher temperatures produced more and faster-swimming sperm than those exposed to lower temperatures.

The study is the first to demonstrate the effects of temperature on the sperm cells of adult fish, and may have significant implications for the impact of climate change on fish fertility.
