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.

研究人员于6月至10月间对鼠兔（pikas）开展捕捉、麻醉、佩戴彩色耳标（ear-tags）标记、非致死性采样操作，随后在捕获原地将其放归。研究样地涵盖海拔与坡向梯度，可为鼠兔对气候及地下微气候变化的响应开展对比研究提供条件。通过在标记鼠兔领地内布设的数据记录仪（data loggers），可采集积雪覆盖度与地下温度的日变化数据。核心研究领地至少会被回访一次，以样带采样法对可用植被进行表征；且每年至少回访一次，以维护数据记录仪并记录鼠兔存活状况。为遗传与生理学研究采集的样本包括体外寄生虫、血液、唾液、尿液、粪便与毛发，同时记录鼠兔的性别、发育阶段、繁殖状态、体重、足长与体温。
