Table 3.

Relative support for models of fecal GCM concentration (n = 31) including effects defined in Table 2 as well as effects of available forage on physiological stress in pikas. Postdeposition predictors are defined in Table 2. Pre‐deposition predictors include average maximum summer temperature (PreDepMaxSumTemp, °C), and total winter precipitation (PreDepWinPrecip, mm) measured during the year preceding deposition of the sample, and factors predictive of pika dynamics in previous studies such as cover of forbs (ForbCover), graminoids (GrassCover), and their ratio. Column headings are described in Table 2
