Caldwell, Chair Professor Eileen Lacey Professor David Lindberg Professor Steve Beissinger Fall 2015 Abstract Movement, Abundance Patterns, and Foraging Ecology of the California Two Spot Octopus, Octopus bimaculatus by Jennifer Krista Kaulalani Hofmeister Doctor of Philosophy in Integrative Biology University of California, Berkeley Professor Roy L. Caldwell, Chair Understanding the reciprocal interactions between animal behavior and other inter-related systems such as physiology, morphology, ecology, and evolution has been called a “Grand Challenge” for organismal biology. Behavior offers two unique contributions to our understanding of organism response to environmental change: 1) behavior is a rapid and reversible response, and 2) organisms can directly influence their surrounding environment, and thus the stimuli their physiological and morphological systems are exposed to, by “choosing” their environment. My dissertation utilizes the temperate octopus Octopus bimaculatus to understand the reciprocal interactions between behavior and ecology in a human-altered landscape. I use a combination of animal population surveys, dietary analysis, mathematical models, and acoustic telemetry to understand the feedback loops been behavior and ecology.
