General linear model (type 3) showing the effects of hemisphere, habitat typea, and temperature on ant species richnessb (Akaike weight: 0.656241c).

aHabitat types: arid shrubland, other shrubland (including a variety of shrublands, scrublands and thickets and other bush dominated habitat types), desert, forest, grassland, savanna, wetland, woodland), and temperature on ant species richness.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. The model shown is the best model based on Akaike weights from a set of all possible models testing the above factors and also the effects of linear and squared terms of latitude (absolute value rounded to the nearest degree) and NDVI (productive energy).
