  • Fish tale: New study evaluates antibiotic content in farm-raised fish
    Antibiotic use in the rapidly expanding world of global aquaculture has been examined in a new study. Results of the research evaluated the presence of antibiotics in shrimp, salmon, catfish, trout, tilapia and swai, originating from 11 countries. Data showed traces of 5 of the 47 antibiotics evaluated.
  • Secrets of dinosaur ecology found in fragile amber
    Ryan McKellar’s research sounds like it was plucked from Jurassic Park: he studies pieces of amber found buried with dinosaur skeletons. But rather than re-creating dinosaurs, he uses the tiny pieces of fossilized tree resin to study the world in which the now-extinct behemoths lived. New techniques for investigating very tiny pieces of fragile amber buried […]
  • Mediterranean, semi-arid ecosystems prove resistant to climate change
    Climate change predictions for the Middle East, like other arid regions of the world, are alarming. But in testing these dire predictions, ecologists found that, contrary to expectations, no measurable changes in annual vegetation could be seen. None of the crucial vegetation characteristics -- neither species richness and composition, nor density and biomas […]

    Biologists have documented fish playing with a bottom-weighted thermometer and other objects. Play, like much of animals' psychology including emotions, motivations, perceptions and intellect, is part of their evolutionary history and not just random, meaningless behavior.
  • Breathing sand: New measurement technique detects oxygen supply to bottom of North Sea
    New analytical methods show for the first time, how the permeable, sandy sediment at the bottom of the North Sea is supplied with oxygen and which factors determine the exchange. Based on the detailed investigation and new measurement technology, the turnover of organic matter and nutrients at the sea floor as well as future changes within the dynamic ecosys […]
