Chesapeake Bay Field Office Environmental Contaminants staff, Sherry Krest and Fred Pinkney, presented findings from two studies at the 2009 SETAC Meeting in New Orleans held November 19-23.  A platform presentation entitled "Effects of lead exposure to southern leopard frogs (Rana sphenocephala) - a biomonitoring project" discussed the results of a 3 year study conducted on Prime Hook National Wildlife Refuge. Sherry Krest presented results showing the level of lead in tadpoles raised in enclosures was declining annually following the removal of 1 acre of soil covered in lead shot.  Sherry also co-chaired a session entitled "Recent Developments in Amphibian and Reptile Ecotoxicology" which included 18 platform presentations and several posters on the subject. 

 

Fred Pinkney presented his findings during a platform presentation entitled "Population Declines in Yellow Perch (Perca flavescens) from Chesapeake Bay Tributaries:  Is there evidence of reproductive impairment?" In this study, he compared the reproductive health of spawning males and females from five tributaries. Abnormal eggs were found in the South and Severn Rivers, both of which have undergone serious population declines.

 

During the conference, U.S. Fish and Wildlife Service Environmental Contaminants biologists were lead authors on 11 platform presentation and 23 posters. The Environmental Contaminants Program also had a booth this year displaying materials and brochures.
