Ectotherms and climate change

Proceedings of the National Academy of Sciences

A model based on life history trait data from different latitudes predicts that ectotherm populations are likely to peak earlier in the year as mean local temperatures rise, but that the populations are likely to peak later in the year if the intensity of seasonal temperature fluctuations increases; warming was not associated with longer activity periods in high-latitude species, because summer temperatures often rose above the animals' physiological limits, providing insights into the potential influence of temperature on the seasonal timing of life history events for ectotherms.
