Revisiting talus and free-air temperatures after 50 years of change at an American pika (Ochotona princeps) study site in the Southern Rockies
Fig 3
Recent and historical monthly maximum and minimum temperature metrics.
Values shown are absolute monthly maximum or minimum temperatures (panels A-C) as well as monthly averages of daily maximum or minimum temperature (panels D-F). All data were recorded at K1 in a pika study site on Niwot Ridge (Boulder County, Colorado, USA). Time periods for historical data (black symbols) and recent data (colored symbols) are shown in Table 1. Historical maximum temperatures (black dots) and minimum temperatures (black triangles) are compared with recent maximum temperatures (red dots) and minimum temperatures (blue triangles) using a cubic-spline smooth to estimate recent means (colored curves) and 95% confidence intervals (shaded regions).
