The study at varying spatial and temporal scales also showed that while the rivers are very similar to each other in terms of the SR values, they do vary with respect to the species composition.

It consists mainly of plateau which has higher elevation of 600 to 900 metres above mean sea … Read more, Karnataka is situated on the western edge of the Deccan Peninsular region of India. Though much of the information of the feeding and habitat preferences of the fishes in this region is lacking, it is speculated that the differences in their activity patterns could be related to feeding and predator avoidance. In our case, the highly diverse and narrowly distributed invertebrates were more efficient as predictors than the less diverse and more broadly distributed vertebrates.

However, despite an overall correlation of the patterns of species richness and complementarity, the efficiency of surrogacy was highly asymmetric; snails and insects were strong predictors of conservation priorities for vertebrates, but not vice versa.
