  1. %VC, variable percentage contribution; TGW, training gain without; TGWO, training gain with only. Data of Discocyrtus prospicuus are from Acosta and Guerrero ([2011]). For each species, variables without values were those not selected to build the MaxEnt model. In each column, the highest values are denoted with italics.
