Center: EERC - Center for Ecological Health Research (Cal Davis)
Center Director: Rolston, Dennis E.
Title: Reproduction of Birds and mammals in a terrestrial-aquatic interface
Investigators: Lasley, Bill L. , Fry, D. Michael , Wilson, Barry W.
Institution: University of California - Davis
EPA Project Officer: Levinson, Barbara
Project Period: October 1, 1996 through September 30, 2000
RFA: Exploratory Environmental Research Centers (1992)
Research Category: Targeted Research , Center for Ecological Health Research
Description:
Objective:To establish the rate-limiting factors affecting the reproductive health of wildlife populations on agricultural land and provide site-specific data for testing ecosystem models; more specifically, to determine how and to what degree the same environmental hazards can result in different adverse effects in wildlife when compared to the adverse effects caused in laboratory animal models.
Expected Results:The observation that the interaction of estrogen and TCDD is different in mammalian and avian species may provide an important clue in understanding both the physiologic basis for gender-specific adverse effects and for differentiating adverse versus benign actions of some environmental toxicants. Studies are underway to compare and contrast the action of estrogen in different life-forms. In addition, the recognition of divergent toxic effects in mammals and birds provides a focus for identification of universal biomarkers for toxic exposures and studies are being designed to identify common down-stream events.
