Dissertation/Thesis Abstract

Physiological consequences of temperature stress on the marine snail, Lottia gigantea
by Gray, Victoria A., M.S., California State University, Long Beach, 2012, 53; 1521623
Abstract (Summary)

Marine intertidal invertebrates are likely to be especially vulnerable to global warming as their physiology, behavior, and demography are all critically inf1uenced by local extreme environmental temperatures. I used the owl limpet, Lottia gigantea, as a model organism to identify the physiological consequences of thermal stress on key demographic parameters. Growth and survival were reduced in response to heat stress in the field but the performance decrement was smaller for limpets with access to more food compared to individuals with access to less. Individual protein expression profiles differed as a function of temperature stress suggesting that limpets were responding to stress by preferentially synthesizing a variety of different proteins as part of the so-called "heat shock response." My results highlight the importance of considering not just one factor in isolation, but rather the potentially complex interactions among multiple environmental drivers of organismal performance.
