POPULATION GENETICS OF WHITE-NEST SWIFTLET Aerodramus fuciphagus. SUB SPECIES IN VIETNAM
Le Huu Hoang, Dang Thuy Binh, Nguyen Thi Anh Thu S u m m a r y
To address bird nest farming development in Vietnam today, on the basis of scientific research state
"Science-based research and propose solutions for sustainable development in the bird nest fanning in
Vietnam ". Salanganes Nest Khanh Hoa Company is the coordination with the Institute of Biotechnology
and Environmental Nha Trang University conducted the study on population genetic of white-nest swiftlet
subspecies in Vietnam, between 01/2012 - 6/2013. White- nest swifdet (Aerodramus) are birds of high
economic value from nests collected. Samples were collected from 4 geographical area: Khanh Hoa, Trang
Bon-Dong Nai, Kien Giang and Con Dao. Phylogeographic tree is based on four algorithms. Maximum
Parsimony and Maximum Likelihood, and Bayesian Inference and Neightbour joining using cytochrome b
gene sequences (Cytb) of the mitochondnal D N A from subspecies Aerodramu 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 three major groups. Among these,
the samples from Trang Bom - Dong Nai and Kien Giang have close relationship with the subspecies of A
fuciphagus amechanus and A fuciphagus vestitus, respctively. Khanh Hoa and Con Dao swiftlet showed
clear separation from the subspecies in Trang Bom - Dong Nai, Kien Giang and subspecies data from
GenBank. Common haplotype was shared by the Khanh Hoa house-switflet populations, Trang Bom -
Dong Nai, Kien Giang and subspecies vestitus, germani and amechanus. Analysis based on gene Cytb
mtDNA has showed that population in Trang Bom - Dong Nai is capable A fuciphagus vestitus subspicies,
Kien Giang population is capable A fuciphagus amechanus, population from Khanh Hoa Island and Con
Dao is likely endemic subspecies in Vietnam.
Key word: Aerodramus fuciphagus, mitochondrial D N A genetic diversification.
