Results of GLMs analyzing relationships between considered variables at different scales and seasons with abundance of <i>L. ampullacea</i>.

The sense of the relationships is shown with + in case of positive relationships and – for negative relationships (i.e. lower abundance with high values for the variable). When the regression was almost flat (scale parameter value<±0.001), we considered it unclear. Statistically significant relationships are shown with an asterisk (*), and the deviance explained in each case is shown in bottom row (in percentage). We used n = 55 in the 100 m scale, n = 50 in 500, and n = 36 in 2500 m.
