Heterogeneous distributional responses to climate warming: evidence from rodents along a subtropical elevational gradient

Table 2 Model selection and model averaging results of models relating the upslope shifts (m) of 11 rodent species’ abundance-weighted range centres to four species traits (body mass, habitat breadth, diet and daily activity pattern), in the Wolong Nature Reserve between 1986 and 2014–2015

The relationships between range shifts and different sets of trait variables were examined with generalized linear regression models, with models sorted by increasing Akaike’s information criterion (AIC_C). Only models with ΔAIC_C ≤2 from the best model are shown in the table. Model-averaged standardized coefficients indicate the relative importance of four traits in predicting the upslope shifts in species’ range centres. The 95% confidence intervals are given below the standardized coefficients
