Long-term patterns in European brown hare population dynamics in Denmark: effects of agriculture, predation and climate

Table 2 Summarised results from the analysis of the impact of agricultural land-use, red fox and winter climate on European brown hare harvest records from 11 Danish counties, 1955–2000. Also given is the change in model deviance (Δ deviance) explained by the variable when fitted last. Type 3 sums of squares.

Note: Due to the standardization of model variables, regression coefficients and Δ deviance values are directly comparable.
