Understanding the means by which ectothermic animals are affected by, and respond to, global climate change is of paramount importance to predicting their future distribution and survival. Physiological research in this area has identified three quantifiable parameters that are useful in estimating the effects of temperature on the survival and distribution of ectothermic animals. These are 1/ the upper lethal temperature or critical thermal maximum (CTMax), 2/ the effect of ambient temperature on resting and maximal metabolic rates, and 3/ the effect of temperature on water balance. The objectives of this proposal are to examine these parameters, as well as their ability to change in the short- and long-term (i.e., acclimatization within a generation and adaptation across generations), in populations of the broadly distributed mosquito species Culex tarsalis. The wide range of this species, stretching throughout western North America, is suggestive of an intrinsic ability to withstand a wide range of thermal environments. By examining populations deriving from sites varying in both latitude and elevation throughout the species? range, the goal of the study is to understand how this species is responding physiologically to climate change.
