Abstract - We investigate genetic variation and biogeography of the cavity-nesting honey bee, Apis cerana, F. in Burma, to add them to the larger picture of A. cerana biogeography in Asia. Non-coding regions of mitochondrial DNA (mtDNA) of 23 colonies collected from 12 localities are sequenced to identify their genetic lineages. Six haplotypes were found (Japan1, Nepal1, ThaiS1, BurmaN1, BurmaN2, and BurmaN3) belonging to two A. cerana mtDNA lineages: Mainland Asian and Sundaland. The Mainland lineage was found in most parts of Burma except the Southeast, where a Sundaland population was found. Studies in Thailand suggested that the Sundaland lineage was not found north of 10° 34' N; this study shows there is a Sundaland population in Burma at 19°-20° N latitude. We propose three hypotheses to explain the presence of the Sundaland lineage in Burma: (1) Burma Sundaland bees are a relict of a formerly more widespread Sundaland population; (2) Sundaland bees migrated to this part of Burma from the southern Thai-Malay peninsula; or (3) transportation by humans.

Key words: Apis cerana / Myanmar / Burma / mitochondrial DNA / biogeography

What is OpenURL?

The OpenURL standard is a protocol for transmission of metadata describing the resource that you wish to access. An OpenURL link contains article metadata and directs it to the OpenURL server of your choice. The OpenURL server can provide access to the resource and also offer complementary services (specific search engine, export of references...). The OpenURL link can be generated by different means.

If your librarian has set up your subscription with an OpenURL resolver, OpenURL links appear automatically on the abstract pages.
You can define your own OpenURL resolver with your EDPS Account. In this case your choice will be given priority over that of your library.
You can use an add-on for your browser (Firefox or I.E.) to display OpenURL links on a page (see http://www.openly.com/openurlref/). You should disable this module if you wish to use the OpenURL server that you or your library have defined.
