Pika demography data for west knoll and Indian Peaks wilderness, 2008 - ongoing.

Pikas are captured, anesthetized, marked with colored ear-tags,
non-lethally sampled, and released at point of capture during
June-October. Study sites include a gradient of elevation and slope
aspect, allowing a comparative study of pika response to variation
in climate and sub-surface microclimate. Daily variation in snow
cover and sub-surface temperatures are measured using data loggers
placed within the territories of marked pikas. Focal territories are
revisited at least once to characterize available vegetation via
transect sampling and at least annually to service data loggers and
record pika survival. Samples collected for genetic and
physiological studies include ectoparasites, blood, saliva, urine,
feces and hair as well as records of sex, stage, reproductive
status, weight, foot length and body temperature.
