California State Parks scientists are running tests this week to determine what caused about 1,500 fish to die in Malibu Lagoon last week, but officials suspect higher-than-normal water temperatures may have played a role.

Many of the dead seals that washed ashore in northern New England in the past few weeks tested positive for either avian influenza or phocine distemper virus, but it is still too soon to say if those viruses are the primary causes of the unusual die-off.

Nine whales have been stranded so far this year in East Iceland. Bottlenose whales and Curvier’s beaked whales are members of the family Ziphiidae and it’s often been said that they are more sensitive to noise pollution in the ocean.

A 10-year study on the Pajarito Plateau shows a 73 percent decrease in abundance and a 45 percent decrease in variety of species.

Marine mammal experts are testing tissue samples for a potential common cause of the surge in carcasses found on the state's beaches this year.

Carcasses examined so far have shown no indication of disease, and tests are pending for harmful algal toxins. Seabirds have been found emaciated and starved, and changed ocean conditions may have affected prey.

Sargassum, a type of seaweed, is creating problems as it washes up across the Caribbean.

The smelly carcass, identified as that of an adult male minke whale, is the second large marine animal to turn up on shore in southern Maine in the past week.

Residents of Chevak and Hooper Bay found two species of sea bird either dead or approachable near the mouth of the Kiuqliiviq and Aprun rivers near fish camps. Residents of Hooper Bay also found a dead sea mammal on the beach.

The iconic pine trees blanketing Jasper National Park may never be the same as a mountain pine beetle epidemic has infected nearly half of the park's pine forest.

Three dead gray whales washed up on two different Kodiak Island beaches recently. The strandings happened within the span of a week.

Weak returns forced the latest restriction. Good news: Sockeye fishing at the Russian River is forecast to be good.

More than 300 wild reindeer have been killed by lightning in central Norway.

“The exact reasons why the return fell at the lower end of the forecast range are unknown at this time, but poorer than average marine survival is a leading candidate.”

Large shearwater die-off at a Pilot Point beach.

Drought and high temperatures have dried the creek and caused thousands of pink salmon and Dolly Varden to die before they could spawn. The event raises questions about vulnerability of area salmon streams to climate change, and for local residents food security.

Swimming moose dies

Scientists first caught on to the strange event when they found thousands of purple sea urchins and other organisms dead in their laboratory tanks.
