Lind, Owen T., 1934-Baylor University.2021-10-112021-10-111998https://hdl.handle.net/2104/11670This study reports on bacterial cell size and abundance change during oxygen depletion of Belton and Stillhouse Hollow reservoir. Bacterial cell size and abundance are compared with amount of heterotrophic nanoflagellates, dissolved oxygen, temperature, and time. The Relative Areal Hypolimnetic Oxygen Demand (RAHOD) was calculated for Belton and Stillhouse Hollow reservoir. Bacterial abundance in Belton and Stillhouse Hollow Reservoir was not greater than bacterial abundance in natural, northern lakes. Bacterial abundance's were not correlated with time, dissolved oxygen, temperature, and nanoflagellate abundance. Bacteria cell sizes in Belton and Stillhouse Hollow Reservoir were smaller than bacterial cell sizes in natural, northern lakes. Bacteria cell sizes were not correlated with temperature or nanoflagellate abundance. The RAHOD of Belton and Stillhouse Hollow Reservoir were lower than the RAHODs of natural northern lakes.application/pdfen-USBaylor University theses are protected by copyright.
