This book was released on 2016 with total page 103 pages. Available in PDF, EPUB and Kindle. Book excerpt: Molecular diet analysis has the potential to overcome the limitations of traditional methods. I used prey hard parts and molecular methods to examine sex-specific diet trends and rockfish consumption of California sea lions (Zalophus californianus, CSL). Fresh scat samples (n=219) were collected from Año Nuevo Island, CA (ANI), during the summers of 2013 and 2014. Prey taxa were identified from fish otoliths and cephalopod beaks recovered from cleaned scats. Sex of the CSL depositing the scat was assigned via multiplex PCR of a CSL microsatellite and a carnivore Y chromosome marker. Prey species also were identified using multiple loci in a Next Generation Sequencing framework. Twenty-two fish and 4 cephalopod taxa were identified from hard parts; additionally, 38 fish and 7 invertebrate taxa were identified from molecular data including 16 rockfish species. Hard parts data overestimated the occurrence of prey with robust hard parts whereas molecular data identified additional taxa that lacked diagnostic hard parts. More scats were assigned to females than males in both years, which may be indicative of greater female use of ANI or an increased presence of non-reproductive females within the Monterey Bay region during summer. Estimates of rockfish consumption in 2013 were similar to previous studies, but fewer rockfish were eaten in 2014 than previously reported. The increased presence of benthic and midwater prey indicated a greater prey base in Monterey Bay compared with previous studies.

This book was released on 2016 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: The United States Marine Mammal Protection Act (MMPA 1972) resulted in federal protection and enhanced the recovery of California sea lion (CSL--Zalophus californianus) populations in the United States. As an unintended consequence of their protection, sea lion populations have expanded their range, negatively interacting with every commercial fishery on the west coast of the United States, predating endangered Pacific salmonids at upriver dams, and damaging docks/fishing vessels. Conservation and management problems with California sea lions can benefit from mechanistic insights into how individuals respond to stimuli and learn about biologically important events. This dissertation provides an in depth examination into how animal learning theory can be applied to conservation issues. I apply learning mechanisms to enhance management of two conservation issues involving sea lions; depredation (removal of fish from fishing lines) and predation of endangered salmonids at the fish ladders below the Bonneville Dam. This dissertation is structured into two reviews, an empirical test of learning on deterrents on California sea lions (Zalophus californianus) interacting with fisheries, an analysis of social transmission and the impact of culling of California sea lions foraging at the Bonneville Dam. Chapter two unpacks the behavioral mechanisms involved in non-lethal deterrents and reviews their application for depredating marine mammals. This review makes the argument that Pavlovian fear conditioning can applied to deterrents to enhance success in cases of human wildlife conflict and reduce management concerns over non-target animals. Chapter three presents a field experiment on Pavlovian fear conditioning for deterrents on wild California sea lions which examines whether conditioned individuals exhibit greater avoidance compared to control animals. Chapter four reviews how learning can be applied to solve conservation problems. Social learning, for instance, functions as a multiplier, rapidly spreading undesirable wildlife behaviors through populations, suggesting that target lethal or non-lethal management strategies may be necessary. Chapter five uses social network based diffusion analysis to show that social transmission is driving foraging of endangered salmonids by California sea lions. Social transmission has implications for management measures, and we used epidemiological models of behavioral transmission to assess current and potential lethal removal strategies.
