Title	Challenges Identifying Endocrine Disruption in Amphibian Field Studies
Contact	mailto:nctcimages@fws.gov
Producer	USFWS/NCTC
Description	Conservation Science Webinar Series: Presented by: Dr. Diana Papoulias, Research Fish Biologist, Columbia Environmental Research Center (USGS). April 17, 2013. During this webinar I will present a case study from research we conducted in Nebraska’s Rainwater Basin (RWB). The area has a high density of wetlands in the midst of intensive agriculture. Concern exists that pesticide and nutrient runoff from surrounding row-crops enters wetlands degrading water quality and adversely affecting birds and wildlife. Frogs may be especially vulnerable. Our objective was to determine whether there was an association between the environmental presence of endocrine disrupting chemicals and biomarkers previously shown to result from exposure to such chemicals. Despite our finding of a number of gonadal abnormalities, data interpretation was hindered because of several factors. I will discuss the results of the study and gaps in our understanding of amphibian biology that make interpretation of field-collected specimens difficult.
