Deployment could lead transformation of toxic HAB monitoring

A new robotic sensor deployed by Woods Hole Oceanographic Institution (WHOI) in Gulf of Maine coastal waters may transform the way red tides or harmful algal blooms (HABs) are monitored and managed in New England. The instrument was launched at the end of last month, and a second such system will be deployed later this spring.

The results will add critical data to weekly real-time forecasts of New England red tide this year distributed to more than 150 coastal resource and fisheries managers in six states as well as federal agencies such as NOAA, the FDA and the EPA. Researchers also plan to add data from the sensor to regular updates provided on the “Current Status” page of the Northeast PSP website. (more…)

Cheating is a behavior not limited to humans, animals and plants. Even microscopically small, single-celled algae do it, a team of UA researchers has discovered.

Humans do it, chimpanzees do it, cuckoos do it – cheating to score a free ride is a well-documented behavior by many animals, even plants. But microscopically small, single-celled algae? Yes, they do it too, biologists with the University of Arizona’s department of ecology and evolutionary biology have discovered.

“There are cheaters out there that we didn’t know of,” said William Driscoll, lead author of a research report on the topic who studied an environmentally devastating toxic alga that is invading U.S. waters as part of his doctoral research in the lab of Jeremiah Hackett, an assistant professor of ecology and evolutionary biology.
