Culturally vital, ecologically unique, and economically valuable, the yellow cedar’s fate is closely tied to snow
Coastal sand ecosystem returning to health after 1.5 years of work
Warmer temperatures and declining sea ice pulls foreign animals and plants to the Arctic, with drastic consequences for these sensitive ecosystems.
Creamy jasmine wildflowers once common in the Colorado high country may be vanishing as climate change brings warmer and drier conditions.
A scientific paper published recently hints at how increasing winter rainfall will affect the Arctic muskox. An N.W.T. biologist says winter rain isn't good for the mammal, but it's actually warmer summers that could prove detrimental.
Habitat of the endangered Vancouver Island marmot is disappearing as the warming climate allows trees to grow higher up mountainsides, turning alpine meadows into forest. Adam Taylor, executive . . .
Serious and unusual outbreaks of illness from eating raw or undercooked walrus to call attention to the risks.
Longer hot, dry spells in the boreal forests that stretch across Alaska and the Northwest Territories create the conditions for wildfires triggered by lightning strikes.
In the Arctic, brown bears (Ursus arctos) are expanding their range northward, in some cases competing with and even mating with polar bears (Ursus maritimus). Beavers (Castor canadensis) have been found as far north as the coast of the Beaufort Sea. The list includes mammals, amphibians, fish and insects.
A new report breaks down climate impacts on health by US region
Some farmers in the United States and Canada have noticed that the quantity and quality of their maple syrup is changing with climate variability. Now researchers who are investigating these observations.
Somebody is poisoning the moose of Anchorage. It's probably you. And many of your relatives, friends, and neighbors. Because the entire city is a garden laced with poisonous plants.
Dust. Trees. Grasses. Mold. How to read the signs about whether 2016 will be gentle or monstrous for allergy sufferers.
Trace 134Cs in northern fur seal tissue suggests that the population under study had been minimally exposed Fukushima-derived radionuclides. Despite this inference, the radionuclide quantities detected are small and no impact is expected as a result of the measured radiation exposure, either in northern fur seal or human populations consuming this species.
A new study from USGS, ANTHC, and the Local Environmental Observer (LEO) Network, provides a view statewide trends in wild berry harvests. The authors conclude that monitoring and experimental studies are needed to understand how climate change may affect the species of wild berries that are important to Alaskans. They also recommended that methods by which rural communities can increase their resilience to declining or more variable berry harvests be explored.
Populations of marine wildlife have plummeted by a half on average over the past 40 years with some species suffering far greater declines as a result of habitat loss, overfishing, rising sea temperatures and worsening ocean acidity, a major report has found.
Since 1976, the distribution of molting Black Brant ( Branta bernicla nigricans ) on the Arctic Coastal Plain has shifted from inland freshwater lakes to coastal marshes, such as those occupying the Smith River and Garry Creek estuaries.
Phytoplankton blooms are increasingly conspicuous along the world's coastlines, and the toxic effects of these blooms have become a major concern. Nutrient enrichment often causes phytoplankton blooms, which decrease water transparency, but little is known about the effects of such light regime changes on whole communities of the continental shelf. A series of simulations designed to evaluate the potential effects of shading by phytoplankton blooms on community organization were conducted using a balanced trophic model of the West Florida Shelf ecosystem and the Ecopath with Ecosim modeling approach. Many functional groups in the system were predicted to decline as benthic primary production was inhibited through shading by phytoplankton, especially when associated biogenic habitat was lost. Groups that obtain most of their energy from planktonic pathways increased when shading impact and associated structural habitat degradation were complemented by enhanced phytoplankton production. Groups predicted to decline as the result of shading by plankton blooms include seabirds, manatees, and a variety of demersal and benthic fishes and invertebrates. Some counterintuitive predictions of declines (mackerel, seabirds, and surface pelagics) resulted because these groups are somewhat dependent on benthic primary production. The overall effect of the simulated bloom-associated shading of benthic primary producers resembled a trophic cascade where the number of full cycles of biomass gains and losses was approximately equal to the number of trophic levels in the system (4.7).

Demonstration of how easy ponderosa pine tree tops can be broken due to the effects of climate change.
Lake Fortune which has unusual under-ice cyanobacterial growth and Lake Beauchamp which is supposed to be low in nutrients as it is mainly fed by groundwater. Cyanobacterial toxicity level is increasing in these two lakes threatening life and livelihood of the local community.
