University of Exeter researchers measured "stable isotope ratios" - a chemical signature also...
The best way to protect corals threatened by climate change is to conserve a wide range of their habitats, according to a study in Nature Climate Change. The finding likely applies to conservation efforts for many other species in...
Even though European nudibranchs are some of the best studied in the world, scientists have now identified three new species. Divers searched around Europe for Trinchesia sea slugs – in the UK, Ireland, Norway, Sweden, Spain, Italy, France, Croatia and Russia.
