Abstract - Nucleus colonies (nucs) of = 4 500 honey bees (Apis mellifera L) were evaluated as an alternative to full-size colonies for monitoring pollution impacts. Fifty nucs were deployed at 5 sites along a transect on Vashon Island, Washington. This provided a gradient of exposure to arsenic and cadmium from industrial sources. After 40 d, statistically significant differences were observed among sites for mean mass and numbers of bees (P ≤ 0.01), honey yield (P ≤ 0.07), and arsenic and cadmium content of forager bees (P ≤ 0.001). These findings are discussed in terms of exposure to heavy metals and observed changes in colony dynamics, especially brood rearing and hoarding of pollen, nectar, and honey.

Key words: Apis mellifera / population dynamics / biological indicator / pollutant

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.
