“The rover helps us understand how much of that carbon might actually make its way into the sediments in the deep sea,” says MBARI marine biologist Crissy Huffard, who coauthored the new paper.
at the University of Washington’s School of Aquatic and Fishery Sciences, with a focus on studying the life histories of rainbow trout in streams and lakes of the Bristol Bay drainage.In the Bristol Bay watershed, lake-migrant rainbow trout swim alongside stream-resident forms.
That, though, would require forest management across swaths of the Arctic, a kind of management we in the US can’t even do right on a small scale .What we’re looking at, then, is yet another complicating factor in the massive complexity that is climate change: When peat burns, it emits lots of CO2, and when peatlands aren’t healthy, they don’t capture any.
A historic slow-moving flood of polluted Mississippi River water loaded with chemicals, pesticides, and human waste from 31 states and two Canadian provinces is draining straight into the marshes and bayous of the Gulf of Mexico —the nurseries of Arnesen’s fishing grounds—upsetting the delicate balance of salinity and destroying the fragile ecosystem in the process.
The International Institute for Sustainable Development’s Experimental Lakes Area, or ELA, are testing grounds that allow researchers to isolate a pocket of water within a lake and add pollutants like hormones and flame retardants—and now potentially microplastics—and watch how the ecosystem responds.
Say hello to your new speaker-lamp. A cervix-navigating robot could save the rhinos. To be fair, these rhinos will need a lot more than a cervix-navigating robot to survive.
On Seymour Norte, officials and conservationists are once again banishing the rats, but the war against invasive species for the purity of the world’s islands has only just begun. Fighting invasive species demands constant vigilance, as the return of rats to Seymour Norte shows.
Looking at streams on Alaska’s Kodiak Island, the researchers found that the varied timing of salmon migrations likely matters as much as abundance. Previous research found that this variance in migration timing among streams matters a lot to brown bears and other wildlife that feed on salmon.
“But we could use aquaculture to replace some of those water filtration benefits, and at the same time grow food.” In places where excess nutrients are a problem, like the Chesapeake Bay, shellfish aquaculture could even help offset the negative environmental impacts of other industries.
A new NASA-led study using data from the Arctic Boreal Vulnerability Experiment (ABoVE) shows that carbon in Alaska's North Slope tundra ecosystems spends about 13 percent less time locked in frozen soil than it did 40 years ago.
While barn owls and western meadowlarks were “losers” during the drought, killdeer and greater roadrunners were “winners.” The blunt-nosed leopard lizard suffered; the side-blotched lizard came up in the world.“The drought kind of knocked down the species that were dominating and allowed the underdogs to do better and stay in the system,” says wildlife ecologist Laura Prugh of the University of Washington, lead author on the new paper in Nature Climate Change.For all the winners and losers, nearly three quarters of species weren’t strongly affected by the drought.
Building on a large body of existing research, they divided natural carbon sinks into 20 different pathways and then calculated both their potential for emissions reductions and the associated costs.
