Temporal trends in population density and mean growing season temperature. Long-term variation in a) mean growing season daily maximum temperature, between 1982 and 2007, and b) population density, between 1981 and 2009, in Adamello (black), Presanella (red) and Brenta (green). Gaps show years with missing data. Whilst the three study areas do differ in their climate, some of the observed inter-site differences in temperature in a) are due to variation in the elevation of weather stations among areas.
