Table 1 Unpredictability and average value (range) of daily average temperature, daily average active time (between 0600 and 2000) temperature, daily maximum temperature, and the length of the breeding season (proxy of reproductive bvalue) for the field sites in Tennessee, New York, Wyoming and Alaska. Higher SDres value indicates greater unpredictability.
