Many species in mountains have to choose between higher temperatures or decreased oxygen levels

By University of Copenhagen 2/11/2020    As a result of global warming many species are currently shifting altitudinal distribution in mountain areas. Even though most move to higher altitudes, there are large differences among species, and some even shift downward to lower altitudes. A recently published paper in the acclaimed journal Frontiers in Ecology and the Environment from the Ecological…

Polar bears in Baffin Bay skinnier, having fewer cubs due to less sea ice

By University of Washington 2/12/2020 Polar bears are spending more time on land than they did in the 1990s due to reduced sea ice, new University of Washington-led research shows. Bears in Baffin Bay are getting thinner and adult females are having fewer cubs than when sea ice was more available. The new study, recently published in Ecological Applications, includes satellite tracking…

Predators to Spare

By UC Santa Barbara 2/12/2020 In 2014, a disease of epidemic proportions gripped the West Coast of the U.S. You may not have noticed, though, unless you were underwater. Fueled by abnormally hot ocean temperatures, sea star wasting disease ravaged these echinoderms from Alaska to Mexico. The condition, still not fully understood, wiped out a significant marine predator, the sunflower star….

Everglades ‘remembers’ severe weather

By National Science Foundation 2/6/2020 The chemical signature left behind by hurricanes, fires, cold snaps and droughts can linger in the slow-moving water of the Florida Everglades for up to a decade, researchers report. No one expected evidence of these disturbances to be detectable in the water for so long and to spread across different areas of the Everglades, the…

The Everglades remember

By Florida International University 2/3/2020 The chemical signature left behind by hurricanes, fires, cold snaps and droughts can linger in the slow-moving water of the Florida Everglades for up to a decade. No one expected evidence of these disturbances to be detectable in the water for so long and spread across different areas of the Everglades. Increased levels of phosphorus, nitrogen,…

Scientists improve understanding of Mount St. Helens eruption recovery

By National Science Foundation 1/29/2020 Through research in the blast zone of Mount St. Helens, Evergreen State College scientists have discovered that plants are influencing the ecosystem’s recovery. A new paper reporting the results, “Plant sex influences terrestrial-aquatic interactions,” was published in the journal Ecosphere by Carri LeRoy and her collaborators at the U.S. Forest Service and the Science Museum of Minnesota. The research,…
