Polluted water is a great source of food for harmful algal blooms, which release even more toxins into the water. And now scientists say that algal blooms may give dolphins Alzheimer’s disease-like brain damage. Anastasia YandulskayaI am a PhD candidate at Northeastern University in Boston. I study regeneration of the nervous system in water salamanders […]

Threats to Cetaceans: There’s More than Meets the Eye

They found that while human activity accounted for a large portion, something else was responsible for a much larger percentage of cetacean death. Rishya NarayananRishya is pursuing an […]

Contaminant fingerprints in fat tell all

This tell-all exposé isn’t from the Maury Show…read on to learn about the use of a nifty chemistry technique that paints a picture of all the contaminants found in the fat of Brazilian dolphins, and what this means for you Anna RobuckI am a third year PhD student at the University of Rhode Island Graduate […]

Rachel Carson had the right idea: DDT persists in unexpected ways in dolphins

Rachel Carson was right to focus her novel on the effects of DDT; DDT persists to this day in dolphins off the California coast in forms that are often not monitored by monitoring programs. Anna RobuckI am a third year PhD student at the University of Rhode Island Graduate School of Oceanography in the Lohmann […]

Sound waves: dolphins in a noisy ocean

As human influence in Earth’s oceans increases, so does the background noise. How might dolphins cope with changes in environmental noise levels, particularly in areas where it has seen a substantial, recent increase? Do chattier dolphins have to invest more energy into their aural physiological systems? Brittney G. BorowiecBrittney is a PhD candidate at McMaster […]
