By University of Hawai’i, Manoa 3/5/2020 The Haleakalā silversword, already one of the rarest species in the Hawaiian Islands, has been declining in recent decades due to drier and warmer climate conditions. Efforts to restore the population should focus on outplanting new plants in geographic areas with the most favorable climatic conditions. That’s according to a three-year study by researchers from…
By the National Science Foundation 3/4/2020 Why are there so many species of plants? Why do some plants thrive, while others don’t? Ecologist Noelle Beckman of Utah State University and her colleagues explore these questions in new findings about seed-to-seedling transitions published in the journal Ecology. The research is supported by the National Science Foundation. “This team used a new approach to analyzing spatial…
By University of Central Florida 3/4/2020 Sea level rise and hurricanes are a threat to sea turtle nesting habitat along national seashores in the Southeast, but a new study predicts the greatest impact to turtles will be at Canaveral National Seashore. The University of Central Florida-led study, which was published recently in the journal Ecological Applications, examined loggerhead and green sea turtle nests…
By University of California Riverside 3/4/2020 Entomologists at UC Riverside have documented that a species of native sweat bee widespread throughout North and South America has a daily routine that makes it a promising pollinator. Because the bee can thrive in environments that have been highly modified by humans, such as cities and agricultural areas, it could become a suitable supplement…
By University of Gottingen 3/2/2020 The threat to insects and other small creatures from rainforest clearance and the consequences for the environment in tropical regions are recognised. What has not been studied so far is whether, and how, the oil palm plantations are able to sustain the populations of tiny below-ground animals that work to keep the soil healthy. In a…
By Tufts University 3/2/2020 MEDFORD/SOMERVILLE, Mass. (March 2, 2020)— Using more than 30 years of earth satellite images, scientists at Tufts University and the non-profit conservation organization Defenders of Wildlife have discovered that habitat loss for imperiled species in the U.S. over this period was more than twice as great on non-protected private lands than on federally protected lands. As…
By University of Washington 2/27/2020 The 2014 Carlton Complex wildfire in north central Washington was the largest contiguous fire in state history. In just a single day, flames spread over 160,000 acres of forest and rangeland and ultimately burned more than 250,000 acres in the midst of a particularly hot, dry summer. The wildfire, driven by strong winds and explosive growth,…
By Utah State University 2/27/2020 Utah State University ecologist Noelle Beckman and colleagues Philippe Marchand of the University of Quebec, Liza Comita of Yale University, Joseph Wright of the Smithsonian Tropical Research Institute in Panama, Richard Condit of Chicago’s Field Museum of Natural History and internationally renowned ecologist Stephen P. Hubbell of the University of California, Los Angeles, explore these questions…
By University Of California, Santa Barbara 2/27/2020 Deron Burkepile, a professor in UC Santa Barbara’s Department of Ecology, Evolution and Marine Biology has been working in southern Africa for longer than a decade, monitoring the complex and diverse plant communities which populate the region. Burkepile first began doing field work in Kruger National Park, South Africa about 15 years ago,…
The Ecological Society of America (ESA) is honored to announce this year’s Katherine S. McCarter Graduate Student Policy Award (GSPA) recipients. This award provides graduate students with the opportunity to receive policy and communication training in Washington, DC before they meet lawmakers.
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…
A new study published in the Ecological Society of America’s journal Ecological Applications examines how warming and increased precipitation (rain and snow) harms the seeds in the ground of the Tibetan Plateau and elsewhere.
By University of New Hampshire 2/18/2020 DURHAM, N.H.—Small mammals such as mice and chipmunks who are not picky eaters play a more important role than previously known in dispersing the spores of wild mushrooms and truffles, according to new research from the New Hampshire Agricultural Experiment Station at the University of New Hampshire. Mushrooms and truffles colonize the roots of…
By CU Boulder 2/13/2020 Two words, and a tiny little creature, strike fear in the hearts of many Colorado outdoor enthusiasts: bark beetle. But new research from CU Boulder reveals that even simultaneous bark beetle outbreaks are not a death sentence to the state’s beloved forests. The study, published this month in the journal Ecology, found that high-elevation forests in the southern…
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…
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….
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…
In Brazil there is a plant so strange that researchers predicted – and 27 years later, proved – that opossums are key to its pollination.
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,…
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,…
