However, despite its wide distribution, there is a need for genetic studies to clarify its evolutionary history and population structure. This research employs DNA barcoding, focusing on the mitochondrial gene cytochrome oxidase subunit I (Cox1), which is effective for species identification and phylogenetic analysis. Blood samples were collected from 70 C. splendens specimens across seven cities in Punjab, Pakistan: Lahore, Kasur, Sialkot, Narowal, Pakpattan, Gujranwala, and Bahawalpur. Genomic DNA extraction was performed, and a partial sequence of the COX1 gene was amplified using PCR techniques. Sequencing of the Cox1 marker from 10 randomly selected specimens revealed nine distinct genetic variants. Interspecific analysis positioned our C. splendens sequences alongside various Corvus species available in GenBank, while intraspecific analysis identified a total of 15 genetic variants. These variants showed nucleotide identity rates ranging from 98.7 to 99.8%, with genetic distances between 0.002 and 0.013. The analysis indicated that the C. splendens group consists of a single heterogeneous clade with variants from multiple countries, including Pakistan, Tanzania, Nepal, South Africa, Malaysia, Sri Lanka, Bangladesh, Kenya, Australia, and Singapore. This study significantly enhances our understanding of genetic diversity and evolutionary relationships within C. splendens populations, highlighting the necessity of genetic research to inform conservation strategies. Further research employing advanced molecular techniques and broader geographic sampling is essential to assess the genetic diversity and population dynamics of this adaptable species. | |
