Outcome of the spatial autocorrelation analyses for andromorph frequency, male density, annual temperature and precipitation normals, using Morans' I index.

Latitudinal and longitudinal effects in these ecological parameters are tested with mixed models. Significant effects are indicated in bold. Given that we tested each parameter four times, we also provide between brackets the adjusted α threshold values based on the sequential Bonferroni correction [91]. Similar patterns were observed for other population and weather parameters (see results).
