Ant presence-absence in response to the plot coordinates (Fig 2), log of the sown plant richness, flood index (only 2013), plant cover, soil porosity (only 2013), soil temperature and interaction between the plant richness and the flood index (only 2013).

Reported are the model coefficients (with standard error in brackets), the p-values associated with the model coefficients, the drop in residual deviance as each term is sequentially added to the model (Deviance) and the p-values associated with this drop based on a chi-square test. The degrees of freedom used in the chi-square test are depicted in subscripts.
