Abstract - Colonies belonging to 4 subspecies of Apis mellifera, namely A. m. capensis, A. m. ligustica, A. m. carnica and A. m. mellifera were placed, one colony per subspecies, at 5 sites with a high floral diversity in the Taunus region in Germany. A total amount of 4008.3 g of pollen loads were trapped during 3 seasons and 214 different pollen types were identified. The comparison of pollen spectra did not result in a separation of the subspecies. Date of sampling and sampling site, however, had a major effect on the composition of pollen samples. Furthermore, subspecies were not significantly different in the structure of dominance, evenness and diversity of pollen types. We conclude that the investigated subspecies of Apis mellifera follow a generalist pollen foraging strategy which may be mainly shaped by natural selection to meet the nutritional and social requirements of populous colonies.

Key words: Apis mellifera / pollen sources / honey bee / subspecies / foraging strategy

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.
