The event caused a die off of up to 95% of marine life along the seabed. The Russia's Academy of Sciences announced that the mass death was due to the effects of toxins from single-cell algae. Environmentalists are conducting their own inquiries and were not yet able to confirm the official probe's findings.

Environmental campaigners said they were conducting their own inquiries and were not yet able to confirm the official probe's findings.

Now believed to be caused by an unprecedented algae bloom, the decimation of bottom-dwelling sea life may have devastating ripple effects.

A broad area of yellow foam is prompting some marine biologists to blame the catastrophe on a harmful algae. However, Governor Vladimir Solodov believes the most likely explanation is a spill. Tests have shown petroleum levels four times higher and phenol levels 2.5 times above normal.

Organizations representing Yukon River communities are drafting a letter to Gov. Mike Dunleavy seeking a fishery disaster declaration for this summer’s

The shrinking of chinook, sockeye, coho and chum salmon has a negative impact on the number of eggs fish lay, but smaller body sizes also mean fewer meals, fewer commercial fishing dollars and fewer nutrients transported into rivers every year.

The size of salmon returning to rivers in Alaska has declined dramatically over the past 60 years because they are spending fewer years at sea, according to a new study led by researchers at the University of California, Santa Cruz, and the University of Alaska Fairbanks.

Asian giant hornets are the largest of all hornet species. This specimen was 1½ inches (four centimetres) long but they can be up to a centimeter longer and have a wingspan the size of a small hummingbird.

A lack of wild bees and managed honeybees is limiting pollination and yields for certain crops on farms in British Columbia and across the United States, a collective of researchers has found.

The number of deaths was more than 13,000

A group advocating for the conservation of wild Atlantic salmon says the number of adult salmon returning to North America rivers fell to near historic lows last year.

The world’s biggest reindeer population is up for big vaccination as regional authorities in the Yamal-Nenets Autonomous Okrug act to stave off outbreaks of anthrax.

Clouds of the insects can stretch for miles, devouring vegetation and destroying crops. Locust experts say time is running out to get the swarms under control because they multiply so quickly.
