Abstract - Mitochondrial DNA from 62 samples of Apis mellifera carnica and A m ligustica collected from within areas of endemism and an area of known introgression was extracted and digested with the restriction enzymes Accl, Bc/l, Bg/II, EcoRI and Xbal. Digestion with Xbal revealed a polymorphism with an asymmetrical distribution between the subspecies. This polymorphism occurs primarily in Austrian and Slovenian A m carnica and may be useful for studying introgression between this race and A m ligustica.

Key words: Apis mellifera / mitochondrial DNA / subspecies / population genetics

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.
