Ecology Disease El Nino ecology population biology sea lion This thesis addresses the threats to two closely related species of sea lion, the Galapagos sea lion (Zalophus wollebaeki) and the California sea lion (Zalophus californianus) using mathematical modeling and statistical methods. We address the potential for a novel disease outbreak in the endangered Galapagos sea lion using a simulation model, which predicts the combined effect of El Nino and disease and how this influences the efficacy of options for management practices. We then characterize how El Nino influences life history traits, including birthweight and survival, in the California sea lion, and examine the characteristics that shape dispersal. We test these effects using statistical methods and identify how and at which life stages sea lions are susceptible to stressors. The broader implications for this work are to make recommendations for management and highlight the importance of understanding the threats facing these species. 2017-06-01 English text Case Western Reserve University School of Graduate Studies / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=case1491654430053451 http://rave.ohiolink.edu/etdc/view?acc_num=case1491654430053451 unrestricted This thesis or dissertation is protected by copyright: some rights reserved.
