Chai HallDissertation-Behavioral-plasticity-and-resiliance-of-a-montane-mammal-in-a-changing-climate to which species can alter behaviors to deal with climate variability is largely an open question. I examined how well thermally specialized animals can proximately buffer warming temperatures through changes in behavior (hereafter behavioral plasticity), using the American pika (Ochofona princeps) HallDissertation-Behavioral-plasticity-and-resiliance-of-a-montane-mammal-in-a-changing-climate as a model species. Pikas are a food-hoarding lagomorph that is sensitive to ambient temperatures, and active year-round in the alpine where conditioHallDissertation-Behavioral-plasticity-and-resiliance-of-a-montane-mammal-in-a-changing-climate

My results indica HallDissertation-Behavioral-plasticity-and-resiliance-of-a-montane-mammal-in-a-changing-climatete that microrefuges were essential to pika occurrence, independent of other critical habitat characteristics, such as forage availability.

Taken together my findings suggest that behavioral plasticity, coupled with adequate accesses to suitable microrefuges and quality vegetation, may provide pikas, and perhaps HallDissertation-Behavioral-plasticity-and-resiliance-of-a-montane-mammal-in-a-changing-climate other thermally specialized animals with a tool to proximately modulate increasing temperatures.
