Fig. 1. Representative microhabitat (red) and air (black) temperatures experienced by C. clavipes in Alaska and Indiana over the three years of the study. Examples were chosen to illustrate the extremes of insulated and uninsulated microhabitats. Note how microhabitat temperatures in poorly insulated sites (in logs above snow levels) closely track air temperatures, while those in well-insulated sites (in logs below snow level) generally remain warmer than air temperatures after snow arrives in winter. (A) Temperatures in a poorly insulated log (off the ground) near Fairbanks, Alaska. (B) Temperatures at a well-insulated site near Wiseman, Alaska. (C) Temperatures in a poorly insulated log near South Bend, Indiana.
