Abstract: The purpose of this study is to determine the effects of nitrates and phosphates on larval Copes 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.
