San Diego Fellowship awards record number of Scripps students, including Garfield Kwan

The San Diego Fellowship awards graduate students disadvantaged backgrounds who have defied odds and overcome adversity. This year, the San Diego Fellowship awarded four Scripps students, one of whom is Garfield Kwan. Garfield is a newly admitted student who has a background in helping the Karen people from the City Heights community. He created and directed the City Heights Outreach Ministry Program to tutor Karen families for three years. He has since stepped down to begin his PhD in the Tresguerres lab.

Dr. Katie Barott wins the Scholander Award from the American Physiological Society

Katie Barott, a postdoctoral scholar at the Tresguerres lab (SIO), has been honored with the Scholander Award for her research in coral physiology during the 2014 American Physiological Society’s Meeting in San Diego. Her talk was titled “Cellular Mechanisms by Which Coral Cells Can Promote Photosynthesis by Their Symbiotic Algae” based on work done in collaboration with Alex Venn and Sylvie Tambutte at Centre Scientifique de Monaco. We are so proud of her accomplishments.

Rising Ocean Acidification Leads to Anxiety in Fish

Scripps News. February 24th, 2014 //

A new research study combining marine physiology, neuroscience, pharmacology, and behavioral psychology has revealed a surprising outcome from increases of carbon dioxide uptake in the oceans: anxious fish.

A growing base of scientific evidence has shown that the absorption of human-produced carbon dioxide into the world’s oceans is causing surface waters to decline in pH, causing a rise in acidity. This ocean acidification is known to disrupt the growth of shells and skeletons of certain marine animals but other consequences such as behavioral impacts have been largely unknown.

In a study published in the journal Proceedings of the Royal Society B (Biological Sciences), scientists at Scripps Institution of Oceanography at UC San Diego and MacEwan University in Edmonton, Canada, have shown for the first time that rising acidity levels increase anxiety in juvenile rockfish, an important commercial species in California. Using a camera-based tracking software system, the researchers compared a control group of rockfish kept in normal seawater to another group in waters with elevated acidity levels matching those projected for the end of the century. They measured each group’s preference to swim in light or dark areas of a testing tank, which is a known test for anxiety in fish. The researchers found out that normal juvenile rockfish continuously moved between the light and dark areas of the tank. However, experiments have shown that fish administered with an anxiety-inducing drug (anxiogenic) prefer the darker area and seldom venture into the light. Hence, dark-preference is indicative of increased anxiety in juvenile rockfish …
