Overwintering and Resident Birds in Qatar: Explorations With DNA Barcoding. [PDF]
We obtained DNA barcodes for 115 birds (34 species, 12 orders) in Qatar, a country with no previous barcode sequence data for wild birds. We provide insights on locally breeding species and overwintering migrants. ABSTRACT Genetic research is unevenly distributed across the globe, with most research done in temperate zones.
