Influence of environmental variables on the models generated using two datasets (SET1 and SET 2) for (a) Notocrangon antarcticus and (b) Nematocarcinus lanceopes.

The top three environmental variables in terms of relative contributions are highlighted in bold for each species. Higher values for the regularised training gain of the jack-knife test indicated greater contribution to the model for a variable (these values were not directly comparable between the different species).*indicates the variable that reduced the gain the most when omitted and therefore contained the most information that was not present in other variables!Indicates the variable with the highest gain when used in isolation and had the most useful information by itself.
