Across the western U.S., wildfires are becoming larger and more severe — and even trees that initially survive are dying in subsequent years, making it harder for forests to regenerate, according to new research from Portland State University.

New research found that the cold, low salinity inshore waters of Icy Strait in Southeast Alaska may have provided a temporary buffer from marine heatwave conditions in the Gulf of Alaska for four species of migrating juvenile salmon.

Oregon State University scientists have improved artificial intelligence’s ability to identify wildlife species in photos taken by motion-activated cameras.

The largest grant in University of Idaho’s history, intended to provide payment directly to Idaho producers for developing sustainable agricultural practices, was terminated last week as a result of new criteria implemented by the United States Department of Agriculture.

President Trump’s proposed budget would end funding of research for America’s bees coordinated by the U.S. Geological Survey Bee Lab. The budget proposal eliminates all $307 million in funding to the Ecosystem Management Area, a division within the USGS that funds biological research, including the Bee Lab.

Scientists say human-caused climate change led to 15,000 additional deaths from wildfire air pollution in the continental United States during the 15-year period ending in 2020.

University of Idaho researchers have developed a mathematical model that simplifies the way scientists understand changes in glacier movement. This new approach demonstrates that diverse patterns of ice flow — ranging from short-term fluctuations to multiyear trends — can be explained using a single set of fundamental equations. 

The blue whale is the largest animal on the planet. It consumes enormous quantities of tiny, shrimp-like animals known as krill to support a body of up to 100 feet (30 meters) long. Blue whales and other baleen whales, which filter seawater through their mouths to feed on small marine life, once teemed in Earth’s oceans. Then over the past century they were hunted almost to extinction for their energy-dense blubber.

Northern pike are moving through salt water to invade freshwater habitats in Southcentral Alaska, according to a new study.

Oregon is becoming warmer and more prone to drought and will see less snow due to climate change, but people and businesses are also adapting to the challenges of a warming planet, the latest Oregon Climate Assessment indicates.

Emissions of carbon caused by fossil fuel pollution continued to grow slightly in 2023 to 36.8 billion metric tons of carbon dioxide, setting yet another new record despite increasingly urgent warnings from scientists about the need for steep and immediate decreases.
