Orthione griffenis, or O. griffenis, eventually kills its host shrimp, and soon the remaining shrimp can’t find each other to reproduce, rendering a blue mud shrimp population extinct.
From the coast of Mexico to the Gulf of Alaska, ocean habitats have seen a startling change recently. Invisible from land, beneath the waves of the Pacific, kelp forests have been fighting a losing battle.
Researchers have found a way to determine the ages of living Cook Inlet belugas using skin samples.
Bears play a well-known role in fertilizing Alaska’s temperate forests. They catch, carry, and digest fish, spreading nutrients through the undergrowth. But two scientists using remote control cameras near Haines show that bears are making contributions on a different front.
When commercial fishermen spool out long lines in pursuit of sablefish— better known to consumers as black cod — seabirds looking for an easy meal dive to steal the bait off the series of hooks. Some unlucky birds get hooked and drown as the line sinks to the deep. And when the drowned bird is an endangered species such as the short-tailed albatross, it triggers scrutiny.
Scientists in Oregon and Washington are noticing a disruptive ocean phenomenon is becoming more frequent and extreme. It involves a suffocating ribbon of low oxygen seawater over our continental shelf. The technical term is hypoxia, sometimes called “dead zones.”
Climate change may be throwing off the Kodiak bear’s eating equilibrium. Oregon State University postdoctoral researcher William Deacy just published findings from a multi-year study of bears on the southwest side of Kodiak Island.
A lot of science involves happy accidents. A retired scientist from Oregon stepped off the ferry in Sitka late last month, and on a hunch decided to look around the woods for an old friend.
Kelly Nesvacil is by the Lily Pond near downtown Dillingham.
because she, like many biologists who study seabirds, wants to know, where have the Aleutian terns gone?
New research suggests Pacific halibut may adapt favorably to increased ocean temperatures. Greenland halibut may not be so lucky.
