Forensic investigation of a hunting incident of Indian porcupine (Hystrix indica) in Uttarakhand: A study to help rein in biodiversity loss

Abstract

Across the world, hunting is one of the main causes of the decline in populations of wild vertebrates. This activity has serious effects not only on the specific, target populations but also on the dynamics and structures of other animal populations. Often the only evidence available for successful prosecution of poachers is in the form of small pieces of skin, bone, and meat. In such cases, forensic investigations can irrefutably establish the identity of the species involved in the illegal hunting by using genetic technologies.

This articles describes an investigative study in a suspected wildlife hunting incident in which molecular biology techniques were employed to identify the species involved. Using fragments of cytochrome b (Cyt b) and 12S ribosomal RNA (12S rRNA) mitochondrial markers, the samples were confirmed to be from an IUCN Red List species, the Indian porcupine (Hystrix indica).This is the first genetic record of an Indian porcupine from the Uttarakhand population.

The genetic analysis in this study was suitable for diagnosing the species and concluding a criminal investigation. Molecular forensic techniques can, therefore, provide an important tool that enables local law enforcement agencies to apprehend poachers. Meanwhile the present study represents a small step in reducing the hunting of porcupine in Uttarakhand as well as other adjoining states, with the aim of conserving biodiversity.
