Warming in the land of the midnight sun: breeding birds may suffer greater heat stress at high- vs low-Arctic sites ...
Rising global temperatures are expected to increase reproductive costs for wildlife as greater thermoregulatory demands interfere with reproductive activities. However, predicting the temperatures at which reproductive performance is negatively impacted remains a significant hurdle. Using a thermore...
