The clock keeps ticking: Circadian rhythms of free-ranging polar bears

Life in the Arctic presents organisms with multiple challenges including extreme photic conditions, cold temperatures, and annual loss and daily movement of sea ice. Polar bears (Ursus maritimus) evolved under these unique conditions where they rely on ice to hunt their main prey, seals. However, very little is known regarding the dynamics of...

About 62,000 dead or dying common murres (Uria aalge), the trophically dominant fish-eating seabird of the North Pacific, washed ashore between summer 2015 and spring 2016 on beaches from California to Alaska. Most birds were severely emaciated and, so far, no evidence for anything other than starvation was found to explain this mass mortality....
