Scientists find the first evidence of genetically modified plants in the wild
Date:8/5/2010

These observations have important implications for the ecology and management of native and weedy species, as well as for the management of biotech products in the U.S."

The poster session "Evidence for the establishment and persistence of genetically modified canola populations in the U.S.," led by Meredith G. Schafer from the University of Arkansas, will be held Friday, August 6, 2010.

Other sessions on invasive species include:

The contributed oral session "Bioeconomic approach to risk assessment for invasive animals in trade in the United States" led by Reuben P. Keller, University of Chicago; the poster session "Hurricane Katrina and the potential replacement of one ecosystem engineer by another on two Mississippi barrier islands" by Christine A. Bertz and J. Stephen Brewer, University of Mississippi; and the poster session "Early detection of invasive plant species: linking management needs with invasive species science" led by Daniel A. Sarr, Klamath Network-National Park Service.

Detecting mercury in bottlenose dolphins

Since 1997, researchers have been collecting skin biopsies from the Sarasota Bay, Florida bottlenose dolphin population as part of an ongoing health monitoring program. Debra L. Miller from the University of Georgia and colleagues performed the first histopathological examination of the biopsies to determine the possible adverse effects and mechanisms of tissue distribution of mercury in the bottlenose dolphin population.

In their upcoming presentation at ESA's Annual Meeting, the scientists will report, among other findings, that mercury concentrations increased in dolphin biopsy samples as the dolphins aged. Results also suggest greater binding of mercury in the skin during the winter season and a possible link between mercury concentration and keratin production. Miller will discuss implications for the conservation of dolphins and other animals and for future knowledge on mercury
