Joan Ruderman's Evaluation of this article at Faculty of 1000 Biology

Posted by NiyazAhmed on 29 Jun 2008 at 08:31 GMT

Joan Ruderman (Harvard Medical School, United States of America) evaluated, rated and endorsed this article at the Faculty of 1000 Biology. His interesting comments are as under:

"Wow! This paper shows that wild-caught male starlings that forage for earthworms in sewage leachfields, which contain high levels of natural and synthetic estrogenic compounds including Bisphenol A, show dramatic changes in song output and song complexity, and changes in regions of the brain thought to control song patterns critical for attracting females. These changes can be reproduced in the lab by feeding the males with worms injected with the environmentally relevant levels of the estrogenic compounds. Of further concern are the findings that (i) the treated males show depressed immune functions and (ii) untreated female starlings prefer the song output from males exposed to these endocrine-disrupting compounds, raising the possibility that birds in the wild might bias their reproductive behavior towards males in poor physiological condition, thus leading to population declines. Makes you think twice about eating worms that come from the sewage treatment plant".
