Fig 4. Predictions of environmentally suitable areas for the occurrence of Allobates femoralis and Allobates nidicola at the scale of the Brazilian Amazon Basin.

Occurrences for each species were separated into 3 groups based on distance for evaluating predictions using model interpolation and extrapolation when sampling was incomplete. Training records for the simulation models are black and validation points are white. Models D and H included all available occurrences of which 20% were randomly assigned by the algorithm to test the models.
