Table 3 Statistics of linear mixed-effects models to test the effects of landscape metrics on the maximum flight distances between roost and foraging sites and home range sizes of mallards in Western Europe

From: Movement patterns of a keystone waterbird species are highly predictable from landscape configuration

  1. Test results are shown for the top model for maximum flight distances, containing both water surface area and total shore length (A), and for univariate models for maximum flight distance and home range size (B). P-values were computed using likelihood ratio tests between the null models and the models containing the metric of interest as only independent variable. Marginal and conditional R2 values were calculated following [52]
