Table 1 Importance of the environmental and anthropogenic variables and the variance explained by traits for each variable. The importance of each variable is described as relative importance. The responses of IAPs to the variables can be partially explained by their traits. This was quantified by the portion of the variance explained by traits (%Var explained by traits)
Variable | Relative importance | %Var explained by traits |
|---|---|---|
bio 3 (isothermality) | 3% | 44% |
bio 4 (temperature seasonality) | 10% | 30% |
bio 5 (max temperature of warmest month) | 11% | 67% |
bio 14 (precipitation of driest month) | 5% | 22% |
bio 18 (precipitation of warmest quarter) | 3% | 22% |
Distance from river | 4% | 67% |
Distance from sea | 3% | 29% |
Road density | 3% | 39% |
