ABSTRACT
To address bird nest farming development in Vietnam today, a study on the population genetics of white-nest swiftlet subspecies in Vietnam was conducted under the scientific research project "Science-based research and propose solutions for sustainable development in the bird nestfarming in Vietnam", which was ca"ied out by Khanh Hoa Salanganes Nest Company in coordination with the Institute of Biotechnology and Environment, Nha Trang University. White-nest swiftlets {Aerodramusfuciphagus) are birds ofhigh economic valuefrom their nests. Island and house swiftlets were collectedfrom 5 geographical areas: Khanh Hoa, Trang Bom- Dong Nai, Kien Giang, Binh Phuoc, and Con Dao between 0112012- 612014. Phytogeographic trees were constructed based onfour algorithms. Maximum Parsimony, Maximum Likelihood. Bayesian Inference and Neighbour Joining using cytochrome b (mitochondrial DNA), and GAPDH (genomic DNA) from the subspecies Aerodramus fuciphagus in combination with sequences from GenBank Haplotype network was built based on Network use Netwoek Draw. The results showed that Vietnamese white- nest swiftlet was classified into two major groups. The samplesfrom Trang Bom -Dong Nai. Binh Phuoc, and Kien Giang have close relationship with the subspecies A. fuciphagus amechanus and A. fuciphagus vestitus. Island swiftlets from Khanh Hoa and Con Dao show clear separation from the subspecies in Trang Bom - Dong Nai, Kien Giang, Binh Phuoc and subspecies datafrom GenBank A common haplotype was shared by the house-switflet populations from Khanh Hoa. Trang Bom - Dong Nai, Binh Phuoc, Kien Giang and subspecies vestitus, germanium and amechanus. Analyses based on gene Cyt-b and GAPDH show thatpopulation in Trang Bom - Dong Nai is A.fuciphagus vestitus, the Kien Giangpopulation isprobably A. fuciphagus amechanus, and, the population from Khanh Hoa and Con Dao is likely endemic subspecies in Vietnam.
