A new paper in Proceedings of the Royal Society B using data from the Continuous Plankton Recorder shows recruitment of young North Sea cod is stronger in cold years than warm years, leading the authors to predict that a full recovery of this stock is unlikely until our warming world cools again.
A study in PLoS ONE suggests the meat of game animals (red-legged partridge) killed with controversial lead shot is more dangerous to people if eaten cooked rather than raw—and even worse if cooked in acidic recipes, say, with vinegar or wine.
Forthcoming in Marine Ecology Progress Series, a paper hypothesizing that emperor penguins gain enough speed underwater to launch into the air and onto sea ice by using “air lubrication”—air bubbles trapped in feathers at dive onset then shed during ascent—a form of drag reduction engineers have learned to use to speed ships and torpedoes through the water.
