General linear model (type 3) showing the effects of hemisphere and latitudea on ant species richnessb (Akaike weight: 6.77 * 10−13c).

aLatitude is the absolute value rounded to the nearest degree.bSpecies richness was ln(x+1)-transformed for analysis.cA global dataset on ant species richness derived from the literature that excludes sites from the FB and SKB is used. Akaike weights are based on a set of all possible models testing effects of hemisphere, latitude (linear and squared terms), habitat type (see Table 2 for a list of habitat types), temperature (linear and squared terms), and NDVI (linear and squared terms) on ant species richness. This simple model is a much worse fit than the model including habitat type and temperature shown in Table 2.
