Figure 2. Relationships between latitude and characteristics of small rodent population dynamics in the small rodent community of Fennoscandian tundra, based on 385 sampling units from 22 locations (Table 1a). The plots for peak interval and community contribution include all sampling units. The plots for mean density, cycle amplitude and skewness include only the sampling units where a given genus was present (n=334, 367, and 305 for lemmings, grey-sided voles and Microtus , respectively). For definitions of population dynamics characteristics variables see Table 2. Lines show fitted values from a loess-smoother and its 95% confidence intervals.
