Table 3. Model results for latitude effects on characteristics of rodent population dynamics. Values in parentheses show 95% confidence limits; predictor variable estimates for which the 95% confidence intervals do not cross zero are denoted in bold. Random effects are given as standard deviation of variation; in parentheses is the proportion of variance assigned to location effect. Stars denote effects of latitude that were statistically significant when data from fall only was included in the models. Unit of latitude is 100 km; the effect size estimate corresponding to a 100 km northwards movement. In all models for community contribution, we log-transformed the response variable to achieve close to normal distribution. Reference level for the factorial variable sampling season is fall; the effect size estimate corresponds to a difference between fall and spring. The community-level models and models for community contribution include all available sampling units, while the other models include only the sampling units where the target genus was present, sample size given in parenthesis.
