These are not good times for the North Atlantic right whale. Ship strikes and gear entanglement play major roles in the mortality of these highly endangered mammals, which now number fewer than 500. Making matters worse, climate-mediated shifts are pushing their prey out of the whales' usual feeding grounds, rendering traditional habitat-focused protection policies less...

Scientists are gaining a better understanding of Pierce's disease and how it affects grapevines. The disease, which annually costs California more than $100 million, comes from a bacterium called Xylella fastidiosa. While the bacterium has been present in the state for more than 100 years, Pierce's disease became a more serious threat to agriculture with...

A study has uncovered the secret to why endangered whale sharks gather on mass at just a handful of locations around the world.

Research led by the University of Sydney shows that under warm water events the nutritional balance of fish and squid changes and is of lower quality, while under cold water events it is of higher quality.

University of Sydney researchers have found monkeys living in the wild in cold snowy habitats adjust their nutrient intake to match the elevated costs of thermoregulation.

Fossils representing two new species of saber-toothed prehistoric predators have been described by researchers from the North Carolina Museum of Natural Sciences (Raleigh, USA) and the Vyatka Paleontological Museum (Kirov, Russia). These new species improve the scientists' understanding of an important interval in the early evolution of mammals -- a time, between mass extinctions, when...
