American Pika (Ochotona princeps) Stress and Habitat Measurements (2018), Niwot Ridge LTER

Description

Niwot Ridge American pika (Ochotona princeps) stress data collected every two weeks from June-September 2018. Stress was measured by observing the amount of glucocorticoid metabolite present in pika feces and sex was determined via genetic analysis of the fecal sample.
