tailieunhanh - Population genetics of white nest swiftlet aerodramus fuciphagus in Vietnam

This study aimed to construct phylogenetic trees to subspecies of swiftlet, thereby detecting and determining the phylogenetic relationships of swiftlet populations in geographical areas in Vietnam, provide the data for the conservation, sustainable exploitation of the bird nest resources. | Journal of Fisheries science and Technology Special issue - 2015 POPULATION GENETICS OF WHITE-NEST SWIFTLET AERODRAMUS FUCIPHAGUS IN VIETNAM Le Huu Hoang1, Dang Thuy Binh2, Nguyen Thi Anh Thu2, Luong Cong Binh1 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 nest farming in Vietnam”, which was carried out by Khanh Hoa Salanganes Nest Company in coordination with the Institute of Biotechnology and Environment, Nha Trang University. White-nest swiftlets (Aerodramus fuciphagus) are birds of high economic value from their nests. Island and house swiftlets were collected from 5 geographical areas: Khanh Hoa, Trang Bom - Dong Nai, Kien Giang, Binh Phuoc, and Con Dao between 01/2012 - 6/2014. Phylogeographic trees were constructed based on four 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 samples from 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 data from 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 that population in Trang Bom Dong Nai is A. fuciphagus .
