The genetic drivers for the successful invasive potential of a generalist bird, the House crow

Abstract

What kind of genetic structure helps the rapid range expansion of the invasive species is fundamental to understand spread of invasion. The House crow (Corvus splendens), an ecological generalist, having a large native and introduced distribution range, is a good study model to investigate the genetic structure and adaptations underpinning the evolutionary potential for successful biological invasion. Thirteen mainland and one island native population from the Indian subcontinent were studied using four nuclear introns and mitochondrial genome to determine the phylogeographic structure and demographic history. A large, panmictic long-term expanding native population dating from the last glacial period (* 30,000 ya) was inferred leading to great genetic diversity across the whole native range. The thirteen mitochondrial encoded proteins, directly involved in the energy supplying pathway, could underlie

“…It has a steady population through an enormous range (Iqbal et al, 2022). Its native countries include Nepal, Bangladesh, India, Pakistan, Sri Lanka, the Maldives, the Laccadive Islands, South West Thailand, and coastal southern Iran.…”
