What caused roughly 60,000 dead murres to wash ashore in Alaska? The answer to this could be very important to the murre (or turr) populations in the Atlantic.

An increasing number of marine researchers say the voracious eaters are thriving at the expense of higher-value sockeye salmon, seabirds and other species with whom their diet overlaps.

Two separate pods of pilot whales have gotten beached on Icelandic shores this summer, RÚV reports, leading experts to apprise locals of how best they can respond to such situations. Marine biologist Edda Elísabet Magnúsdóttir says that such beachings are becoming a yearly occurrence – an indirect result of warming ocean temperatures – and likely […]

For example, when looking at water in some areas around St. Lawrence Island, from 2010 to 2017, the bottom temperature went up by eight degrees Celsius (about 14° Fahrenheit).

Stop land damage and change food production to halt climate crisis, United Nations scientists warn in second IPCC report

Somewhere between the size of a sewer rat and a beaver, with a tail resembling that of an opossum and protruding, nacho cheese-colored teeth, the nutria is both impressively unattractive and highly destructive.

Average temperature for month amid Arctic heatwave was 58.1F (14.5C), nearly 1F above previous high set in July 2004

These tiny, black, thread-like pests dig into plants and like to hang about in gangs, which is why you see so many of them. It is as if they want to be as annoying as possible.

More than a month’s worth of rain has soaked parts of the state in just a few days, setting records.

Bees, butterflies, and other insects are under attack by the very plants they feed on as U.S. agriculture continues to use chemicals known to kill.

Around the world, 17 countries are currently facing extremely high water stress. Climate change is making the problem worse.

Global warming is shrinking the permanently frozen ground across Siberia, disrupting everyday life in one of the coldest inhabited places on earth.

These changes seem to be heralding population spikes and downturns for a number of species like walleye pollock and Pacific cod, and even more pronounced in small, fatty forage species.

A total of 161 great white sharks have been spotted off the coast of Cape Cod, Massachusetts, since June. Experts say attacks on people are unlikely as the sharks are looking for seals.

Salmon have been found dead in rivers across Western Alaska this summer. The largest die-off reported comes from the Koyukuk River, a tributary of the Yukon.

We isolated Japanese encephalitis virus (JEV) from brain samples of 2 seals with lethal encephalitis at Weihai Aquarium, Weihai, China, in 2017. We confirmed our findings by immunohistochemical staining and electron microscopy. Phylogenetic analysis showed this virus was genotype I. Our findings suggest that JEV might disseminate though infected zoo animals.
