The 2008 Edwin W. Pauley Summer Program in Marine Biology, entitled “Hormones and Environment”, focused on developing a better understanding of the mechanisms by which marine vertebrates are able to adapt to changing environments and environmental conditions and developing techniques to measure these adaptations both qualitatively and quantitatively. An important component for our consideration was how environmental salinities affect teleosts on the levels of the cell, organ, and whole organism.
Thirteen visiting researchers and 18 graduate, undergraduate students and post-doctoral fellows from Japan and the U.S. participated in the 24th Annual Edwin W. Pauley Foundation Summer Program in Marine Biology at Coconut Island. Besides providing opportunities for students to conduct research in environmental physiology of marine animals, we had three major goals. The first goal was to review current information and discuss future research directions. This goal was met through attendance of 20 high quality lectures covering cutting edge research on a variety of fields including islet cell transplant for diabetes research, large scale breeding of hybrid striped bass, passive tracking of hammerhead sharks, and cellular adaptation to changing salinities in several organs and organisms. Our second goal was to provide students with the cognitive and technical skills that will enable them to thrive in their profession. This goal was met by a variety of different workshops throughout the summer; these included establishing ovulation stage and manual stripping of female tilapia, developing a novel technique to cannulate the esophagus of tilapia, comparative anatomy of reef fishes, gen cloning techniques, and establishment of a reporter gene assay system. Also, the graduate and undergraduate students participated in several on going research projects that were being conducted throughout the summer. Our last goal was to advance the state of knowledge through the publication of results of student research in peer-reviewed scientific journals. We have 3 original papers either in press or submitted and 3 (Lori feed, Jason, Kai) original papers in preparation as a result of the experiments conducted during the summer program. Furthermore, we have 4 (Lori, Andre, Jason) follow-up experiments in progress.
We thank the Pauley Foundation for their generous and continuing support of this summer program. The Pauley funds helped support the research as well as travel, housing costs and meal allowance for all visiting faculty and students. Dr. Stephen Pauley covered the travel expenses for two students from Pomona College. In addition, several participants were able to cover their own travel expenses.
