dc.description.abstractSenescence is a process of physiological deterioration observed in individuals advancing in age which is characterized by decreasing rates of survival and reproduction. Selective pressures are thought to eliminate individuals before geriatric ages can be reached and the intensity of pressure believed to shape patterns of survival in a population. My thesis examines how simple environmental stressors may affect senescence in Lemna turionifera, an aquatic macrophyte, and explores the possibility of observing senescence under more realistic circumstances. In these experiments, I observed that survival and reproduction of L. turionifera fronds can be influenced by specific stresses, e.g., salinity, and resilient against others such as tissue damage. With respect to realistic observations of senescence, I attempted to construct an apparatus for such an undertaking that succeeded in early observation attempts.en_US
