Abstract
An analysis of the infraspecific categories of Apis cerana was prepared from the relevant literature on taxonomy, morphometrics, allozyme polymorphism and mtDNA diversity. About 31 putative biometric groups have been proposed and assigned to about eight equivocal "subspecies"and various ecotypes. However nearly half of the area of distribution of A. cerana remains unexamined. Allozyme polymorphism is greatest in southeast and lowest in northern and western Asia. About four major mtDNA groups are discernable. There is a very low overall geographic congruity amongst the morphoclusters, allozyme polymorphs and mtDNA clusters. The greatest problems in resolving infraspecific categories in A. cerana are inadequate sampling, incompatible differences in sample sizes, character suites, sampling distance, confidence limits and range of geographical scales employed in different studies.

Key words: Apis cerana / taxonomy / biogeography / Asia / honeybees

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.
