DNA Barcoding as a Tool for Species Identification in Freshwater Ecosystems
Abstract: Freshwater ecosystems are biodiversity hotspots but remain under constant threat from anthropogenic activities. Traditional taxonomy often struggles with cryptic species and morphological variability. DNA barcoding, particularly using mitochondrial cytochrome c oxidase I (COI), has emerged as a standardized molecular tool for species identification. This paper reviews the methodology, applications and limitations of DNA barcoding in freshwater ecosystems, highlighting its role in conservation, bio monitoring, and ecological restoration.
Keywords: DNA barcoding, freshwater ecosystems, COI gene, biodiversity monitoring, molecular taxonomy, conservation genetics
