This project was desinged to aid the Missouri Department of Conservation in characterizing and quantifying the: 1) interactions between biological and non-biological components of the ecosystem; 2) ecosystem variability as caused by natural and anthropogenic influences; and 3) vulnerabilities of ecosystems to land-use practices, disease, and contaminants. The project has an expected completion date of 2009.

This project will provide non-lethal methods for resource managers to assess the reproductive health of razorback sucker populations in the Colorado River basin. Objectives are to develop ELISA bioassay specific to razorback sucker for measuring vitellogenin and to determine “normal” concentrations of vitellogenin and steroid hormones (17b-estradiol and 11-ketotestosterone) to help evaluate these reproductive biomarkers in few populations that are reproductively viable (eg Las Vegas Wash and Lake Mohave). To date, the ELISA bioassay to measure vitellogenin in razorback sucker has been developed and samples to characterize the annual cycle of vitellogenin and steroid hormones are being collected. This project has an expected complete date of 2010.
