Abstract
Abstract Swamp deer (Rucervus duvaucelii) is an endemic, Scheduled I species under the Wildlife (Protection) Act 1972, India. According to variations in antler size, it has been classified into three subspecies, namely Western (R. duvaucelii duvaucelii), Central (R. duvaucelii branderi), and Eastern (R. duvaucelii ranjitsinhii). For planning effective ex situ and in situ conservation of a wide-ranging species in different bioclimatic regions and in wildlife forensic, the use of genetic characterization in defining morpho/ecotypes has been suggested because of the geographic clines and reproductive isolation. In spite of these morphotypes, very little is known about the genetic characteristics of the three subspecies, hence no strict subspecies-based breeding plan for retaining the evolutionary characteristics in captive populations for subsequent re-introduction is available except for a few studies. We describe the genetic characteristics of these three subspecies using cytochrome b of the mtDNA genome (400 bp). The DNA sequence data indicated 11 variable sites within the three subspecies. Two paraphyletic clades, namely the Central India and Western-Eastern populations were found, whereas the Western and Eastern populations are monophyletic with a bootstrap value of 69% within the clade. We suggest the need of sorting these three subspecies using different molecular mtDNA markers in zoos for captive breeding purposes so as to retain the genetic diversity of the separate geographic clines and to use a subspecies-specific fixed-state nucleotide to assess the extent of poaching to avoid any population demography stochastically in India.
期刊介绍:
Mitochondrial DNA Part A publishes original high-quality manuscripts on physical, chemical, and biochemical aspects of mtDNA and proteins involved in mtDNA metabolism, and/or interactions. Manuscripts on cytosolic and extracellular mtDNA, and on dysfunction caused by alterations in mtDNA integrity as well as methodological papers detailing novel approaches for mtDNA manipulation in vitro and in vivo are welcome. Descriptive papers on DNA sequences from mitochondrial genomes, and also analytical papers in the areas of population genetics, phylogenetics and human evolution that use mitochondrial DNA as a source of evidence for studies will be considered for publication. The Journal also considers manuscripts that examine population genetic and systematic theory that specifically address the use of mitochondrial DNA sequences, as well as papers that discuss the utility of mitochondrial DNA information in medical studies and in human evolutionary biology.
