Response curves of MaxEnt models. Response curves of MaxEnt models created using only the corresponding variable for (A) P. fallax; (B) Marmorkrebs in Madagascar and Germany; (C) Marmorkrebs in Madagascar, Germany, and Sapporo; (D) P. fallax and Marmorkrebs in Madagascar and Germany (E) P. fallax and Marmorkrebs in Madagascar, Germany, and Sapporo. Note that the variables used in this study are not correlated, and thus the graphs reflect the dependence of predicted suitability on the selected variable. The inclusion of the individual Marmorkrebs found in Sapporo has virtually no effect on the response curves (compare column B to C, or column D to E). Wild P. fallax and parthenogenetic Marmorkrebs show different optimal responses to variables, except for mean temperature of driest quarter. Such different responses would explain the bimodal curves of mean temperature of wettest quarter, the hump-shaped curves of precipitation seasonality or precipitation of wettest quarter, or the asymmetrically humped curves of precipitation of driest quarter in rows D and E.
