Phylogeographic analysis reveals genetic structure of blackbuck (Antilope cervicapra) in India
The blackbuck (Antilope cervicapra) is endemic to the Indian subcontinent. It occurs in a wide variety of habitats that range from open plains, grasslands, scrublands, and lightly forested areas. The current study provides insights into the existing genetic variation in blackbuck populations, which is crucial for enhancing population fitness and long-term survival. To understand the phylogeny and genetic diversity of blackbuck, we processed the pellet samples (n = 233) from 18 locations across their distribution range in India for MtDNACytb and control region. High haplotype (0.991) and nucleotide diversity (0.033) were observed in the populations. The mtDNA-based AMOVA indicated 41.73% genetic variations among the blackbuck populations of India. The results confirmed that the blackbuck has a unique haplotype in different locations that is not shared by other populations. Geographically, our results identified four genetically distinct clusters: Northern, Southern East, Southern West and Eastern central regions of India. The study reveals that an ancestral population initially separated into two groups, leading to the formation of the North and South clusters. Subsequently, the South population diverged further into three clusters: Southeast, Southwest, and Eastern-central populations. Neighbor-joining analysis suggested the Eastern-central region as part of the Southern East region, while Bayesian phylogeny indicated a separate clade emerging from the Eastern-central region at a later time. Bayesian skyline plots revealed a history of population equilibrium in the Northern region followed by a recent population expansion in Southern East, Southern West and Eastern-central regional populations. Demographic analysis suggests that blackbucks have effectively adapted to their respective landscapes.
期刊介绍:
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
