Sediment samples were collected from the North Bosque River and South Bosque River which drain into Lake Waco for five months during flood events and low water flow. Measurements for population parameter changes were made after the rotifer cysts were subjected the materials leached off the floodborne sediment (elutriates). B. calyciflorus population growth and birth rates were inhibited and their death rates were stimulated when subjected to ambient elutriate concentrations containing contaminants from the North Bosque River. Population parameters remained statistically unaltered for the South Bosque River samples.application/pdfen-USBaylor University theses are protected by copyright.
