The diversity of Apis cerana Fabr. in the Philippines was studied using morphometric methods. A total of 101 samples of A. cerana from feral and hived colonies, and foragers were collected throughout the Philippine archipelago. The 39 morphometric characters recommended by Ruttner and Ruttner et al. were measured. The data were statistically analyzed by means of factor analysis, discriminant analysis, and cluster analysis. The bees from Palawan were unequivocally distinct and separate from the other Philippine samples. The bees from the other Philippine islands still showed a high degree of variation. The bees of Luzon differed clearly from those of Visayas and Mindanao. Within Luzon, the bees from the highland differed clearly from those in the lowland and were regarded as separate groups. Bees from Visayas and Mindanao were still very variable and showed potential for further sub-structuring. The present analysis could not distinguish whether the difference between Luzon and Visayas-Mindanao was based on a north-south clinal structure, or on distinct groups.

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 You should disable this module if you wish to use the OpenURL server that you or your library have defined.
