Abstract:

Seven Apis mellifera carnica queens were instrumentally inseminated with the semen of their own sons. Diploid drone offspring of these queens were raised using two established techniques including elaborate laboratory manipulations, and a new approach. The new approach, based on routine beekeeping, uses small mating nuclei, which rear diploid drones to the adult stage late in the season. No labour and cost intensive feeding, nor grafting and incubation steps are needed. The ploidy level of the drone offspring was evaluated using seven DNA microsatellites. All drones reared by the elaborate techniques and more than 90% of the drones reared in a small mating nucleus were definitely diploid. This technique allows for easy and simple diploid drone rearing even in research groups with no sophisticated equipment.

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.
