A pioneering Cornish research partnership is providing invaluable information to the UK’s shellfish industry by improving understanding of what seafood people choose to eat and why.
University of Exeter Medical School PhD student, Nick Boase, is conducting surveys across the country to shed light on what people understand about shellfish, and uncover reasons why they might shy away from consuming produce grown in the UK. (more…)
The public is invited to help identify objects they see in images of the seafloor through a new interactive website called “Seafloor Explorer.” The result of a unique collaboration between oceanographers studying seafloor habitats, Web programmers and social scientists, Seafloor Explorer (www.seafloorexplorer.org) launches September 13.
The team has more than 40 million images, but are launching the site with a preliminary set of 100,000 – all of them taken by HabCam, a habitat mapping underwater vehicle. HabCam was developed and built by the HabCam group, which comprises marine biologists and engineers from the Woods Hole Oceanographic Institution (WHOI) as well as fishermen and other scientists. The Seafloor Explorer interactive website was funded by a grant from the Alfred P. Sloan Foundation, and built in collaboration with the HabCam Group by the Citizen Science Alliance (CSA), the developers behind interactive sites found on Zooniverse.org. (more…)
A new study indicates that mass extinctions affect the pace of evolution, not just in the immediate aftermath of catastrophe, but for millions of years to follow. The study’s authors, University of Chicago’s Andrew Z. Krug and David Jablonski, will publish their findings in the August issue of the journal Geology.
Scientists expected to see an evolutionary explosion immediately following a mass extinction, but Krug and Jablonski’s findings go far beyond that.
“There’s some general sense that the event happens, there’s some aftermath and then things return to normal,” said Krug, a research scientist in geophysical sciences at UChicago. But in reality, Krug said, “Things don’t return to what they were before. They operate at a different pace, sometimes more rapidly, other times more slowly. Evolutionary rates shift, and that shift is permanent until the next mass extinction.” (more…)
