TABLE 1.

Summary of mean temperatures and standard deviations (SD) during summer (15 June–15 September; measurement period 2018‐2020) from data loggers at the North Mono Craters site (re‐occupied in 2021) and five mid‐elevation sites (continuously occupied “typical” pika sites in the adjacent Sierra Nevada).

Pika sites	Elevation (m)	Summer temperatures °C
		Mid‐day		SD		Night		SD
		Surf	Mx	Surf	Mx	Surf	Mx	Surf	Mx
North Mono Craters (1 site)	2195	33.2	7.3	4.1	1.5	12.4	6.7	4.2	1.0
Sierra Nevada (5 sites)	X = 2835	24.4	16.9	6.3	4.3	15.4	15.9	3.9	4.1

Note: Temperatures are given for the talus/lava surface (Surf) at a resident pika's haypile and the talus/lava matrix (Mx; 0.5–0.75 m below the talus surface). Summer mid‐day readings taken at 1200, 1600 h; Summer night readings taken at 2000, 2400, 0400 h.
