The field study has been completed and we are now analysing the data we have collected. While the discovery has been an interesting and important, even though unexpected, milestone, the investigation into the impact of global warming on the pika population is still going on. We have published our finding in the journal Molecular Phylogenetics and Evolution and have proposed that the new species be named Ochotona sikimaria. And the genes of each of the species within the family are still to be mapped. But pikas, especially in the Himalayan region, have not been studied extensively. It is quite common in Sikkim, and its specimens are found not just in India but also in museums abroad. It was a surprising find considering that the pika that we were studying was not rare by any means. Surprisingly, this pika’s DNA sequence was nowhere close to its sister species, those it resembled the most within the family.īy this time, it was becoming clear to us that we were looking at a new species in the pika family that was so far being wrongly labelled a sub-species. The differences in DNA sequences remained. We then decided to extract the DNA directly from the pika, for which we captured a few of these animals. But the differences in the DNA sequences of the samples collected by us and in existing repositories forced us to look at our methods more closely. Since pikas are herbivores, this was not a very big concern. In carnivorous animals, the faeces can also contain the DNA of the prey. Now, faecal matter as a source of DNA can be a tricky affair. ![]()
