Revisiting talus and free-air temperatures after 50 years of change at an American pika (Ochotona princeps) study site in the Southern Rockies
Fig 8
Recent and historical free-air temperatures at K1 and D1.
Data recorded at the K1 pika study site and D1 alpine weather station on Niwot Ridge (Boulder County, Colorado, USA). Means (curves) and 95% confidence intervals (shaded regions) were estimated using a cubic-spline smooth. See Table 1 for years associated with each period, and Table 2 for temperature metrics.
