Insect populations are declining dramatically in many parts of the world, recent studies show. Researchers say various factors, from monoculture farming to habitat loss, are to blame for the plight of insects, which are essential to agriculture and ecosystems.
Water quality in Anchorage's lakes is generally good, but swimmer's itch is a risk.

The divide between Atlantic and Arctic isn’t just geographical, it’s physical. And the physics are changing.
Warming waters have reduced the harvest of Alaska's prized Copper River salmon to just a fraction of last year's harvest, Alaska biologists say.
Single-family homes near sea level in Miami-Dade County are increasing in value at a slower rate than ones at elevation, according to a new research study
Bird Notes columnist Julian Hughes of RSPB Conwy reveals how the Snowy Owl got twitchers in a flap, and outlines 11 birding events in the coming days
Over 30 years the world’s annual temperature has warmed nearly 1 degree according to the National Oceanic and Atmospheric Administration
Bill Cissel, Extension Agent – Integrated Pest Management; bcissel@udel.edu and David Owens, Extension Entomologist, owensd@udel.edu We have recently captured a large number of green stink bug adults in our black light traps. While there are no established thresholds or recommendations based on trap catches for stink bugs, this does alert us to the fact that …
It’s well established that Arctic ice is changing in dramatic ways. As the climate warms, ice coverage is decreasing, the amount of multiyear ice has gone down significantly and in
ANCHORAGE — The commercial salmon harvest in Alaska's Copper River is so far the second lowest in 50 years, state officials said. The Alaska Department of Fish and Game's fish...
In the fall of 2014, West Coast residents witnessed a strange, unprecedented ecological event. Tens of thousands of small seabird carcasses washed ashore on beaches from California to British Columbia, in what would become one of the largest bird die-offs ever recorded.

The frequency of high-tide flooding has doubled in 30 years. Some cities faced more than 20 days of it in the past year, and not just during hurricanes.
Fairbanks International Airport and Eielson Air Force Base no longer use a type of firefighting foam containing a chemical compound that’s contaminated groundwater around the city, and that poses a potential threat to human health.
The combination of abundant rain and snowfall and extremely warm mean annual air temperatures may have led to the destabilization of permafrost around lake margins. Rapid snow melt and high amounts of excess meltwater further promoted rapid lateral breaching at lake shores and consequently sudden drainage of some of the largest lakes of the study region.
An oxygen-starved area of almost 165,000 square kilometres in the Gulf of Oman is now the world’s largest marine “dead zone.” Incapable of supporting
Every year, billions of animals migrate across the globe, carrying parasites with them and encountering parasites through their travels.
Considered the most destructive pest slug in Europe, the Spanish slug, or Arion lusitanicus, or Arion vulgaris, or sometimes Geoff (there’s some controversy over the name, thanks to the fact that the Arion genus contains up to 50 species and they all look a lot like one another) is between 7-15cm long and can weigh up to 15kilos if it’s sitting on a dog.
April should be prime walrus hunting season for the native villages that dot Alaska's remote western coast. In years past the winter sea ice where the animals rest would still be abundant, providing prime targets for subsistence hunters. But this year sea-ice coverage as of late April was more like what would be expected for mid-June, well into the melt season. These conditions are the continuation of a winter-long scarcity of sea ice in the Bering Sea-a decline so stark it has stunned researchers who have spent years watching Arctic sea ice dwindle due to climate change.
