Map details: The predicted distribution of the Anopheles dirus species complex mapped using hybrid data (372 occurrence data plus 500 pseudo-presences weighted at half that of the occurrence data and randomly selected from within the Expert Opinion (EO) range). Pseudo-absences (3720) were generated at a ratio of 10:1 absence to presence points, and were randomly selected from within the 1500 km buffer surrounding the EO (EO shown in the inset map). Predictions are not shown beyond the buffer boundary. The black dots show the 372 occurrence records for the complex. Map statistics: Deviance = 0.1738, Correlation = 0.8793, Discrimination (AUC) = 0.9857, Kappa = 0.8451. Environmental variables: 1. LST (P1), 2. Prec (A1), 3. MIR (P1), 4. NDVI (mean), 5. LST (P2), (see Additional file 2 for abbreviations and definitions). Copyright: Licensed to the Malaria Atlas Project  under a Creative Commons Attribution 3.0 License. Citation: Sinka et al.
