WATER RESOURCES RESEARCH GRANT PROPOSAL

Project ID: 2006KY65B

Title: Lethal and Sublethal Effects of Agricultural Nutrient Pollution on Tadpoles

Project Type: Research

Start Date: 03/01/2006

End Date: 02/28/2007

Congressional District: KY 6th

Focus Categories: Ecology, Agriculture, Nutrients

Keywords: amphibian toxicology, developmental stability, nitrate, phosphate

Principal Investigator: Whiteman, Howard H.

Federal Funds: $5,000

Non-Federal Matching Funds: $10,000

Abstract: The purpose of this study is to determine the effects of nitrates and phosphates on larval Cope's gray treefrogs, Hyla chrysoscelis, by measuring survival, growth, time to metamorphosis, and developmental stability (as measured by deviations from a normal phenotype). This study will examine both the lethal and sublethal effects of these nutrients in constant concentrations and in pulses, to better understand how such pollutants might actually affect amphibians in nature.
