Dataset: Impact of extreme temperature event on life history and behaviour in newt embryos

Dataset: Impact of extreme temperature event on life history and behaviour in newt embryosCurrent climate change is increasing the frequency and intensity of extreme temperature events. We exposed three- or ten-day-old embryos to different regimes of extreme temperatures for three days. Our results show that exposure to different extreme temperature regimes led to a shortened embryonic development time and an increase in hatchling length, while not significantly affecting embryonic survival. The duration of development was sensitive to the timing of temperature extremes, as early exposure accelerated embryo development. Exposure to temperature extremes during embryogenesis heightened the exploratory activity of hatched larvae.
