Sierra Nevada Aquatic Research Laboratory

30 Sep, 06 PM - 05 Oct, 01 PM

The purpose of this visit is to understand the selective forces that snow cover exerts on overwintering insects. Climate change is dramatically altering environments across the planet, and the high Sierra is no exception. In the Sierra Nevada Mountains there is predicted to be warmer winters and decreased precipitation. This will impact organisms that overwinter in soil, by decreasing snow cover, which acts as an insulator from air temperatures. Decreasing winter snow paradoxically means decrease in winter temperatures. I plan to test if the willow beetle Chrysomela aeneicollis will have differential selection acting between conditions. This was done by burring beetles at the Rock Creek Lodge in a plot with snow removed and one exposed to ambient snow fall. During this visit I plan to collect the overwintering beetles (Chrysomela aeneicollis) as they terminate diapause.
