Figure 1: ROC and TSS Score of the models of a. Ganges River Dolphin and b. Indus Dolphin

The distribution modeling of both the dolphins are very much restricted to its own basin (Figure 2). Habitat of the species are mostly concentrated in the mainstem for both the species. The potentially suitable current habitat of Indus dolphin are concentrated in the south-western Indus Basin whereas the Ganges River Dolphin are concentrated in southern and central GBM basin.

The niche overlap is concentrated more in GBM basin than the Indus basin. In the Indus only the mainstem features low habitat suitability overlap (falling in 0-250 score range against an index of 0 - 1000 habitat suitability score, higher the score higher the habitat suitability prediction). The model is a projection and does not actually represent the actual distribution. The presence of dams and canals which have been catastrophic to the dolphin population has not been accounted here.
