Chemical ecologists translate the language of the sea
If Dr. Dolittle could talk to the animals, it's more likely he was a chemical ecologist than a linguist, says marine scientist Mark Hay of the Georgia Institute of Technology in Atlanta—at least when it ...
Study shows depleted fish stocks can come back from the brink
(Phys.org) —Nature is a lot more resilient than we sometimes think. A study by Rutgers marine scientists published recently in Science shows that species of fish that have been overfished for decades can of ...
Trawling is changing seafloor habitats: study
Bottom trawling is dramatically altering the ocean floor and harming habitats, similar to the way that farming has permanently changed the landscape, a study said on Wednesday.
