Abstract
To accompany: Return of the pika: American pikas re-occupy long-extirpated, warm locations by Constance I. Millar and Andrew T. Smith, Nature Notes.
American pika re-colonization sites identified in this study
Bodie State Historic Park – Noonday Mine 38.004 N; -119.1005 W; 2,615 m Site also clearly identified in maps in Smith (1974a), Smith & Gilpin (1997), Smith & Nagy (2015).
North Mono Craters Site 37.9116 N; -118.9985 W; 2,145-2,250 m
Methods
The primary data include temperatures (deg C) from mini-thermochron units placed in American pika habitats. These include temperature data from pika haypile surfaces and ~0.5 m below the haypile in talus matrices.
Usage notes
Comparative temperature data
The following four .txt files contain thermochron temperature data (Maxim iButtons) for summer 2019 through summer 2020 at two pika sites: 1) North Mono Craters (recently re-colonized) and 2) Virginia Canyons (long extant). The files represent a thermochron placed on the surface of the haypiles and a thermochron in the matrix (0.5 m depth) of the talus below the haypile.
