Does the public trust what scientists say?
October 6, 2014 03:58 PM - Princeton University
If scientists want the public to trust their research suggestions, they may want to appear a bit "warmer," according to a new review published by Princeton University's Woodrow Wilson School of Public and International Affairs. The review, published in the Proceedings of the National Academy of Sciences (PNAS), shows that while Americans view scientists as competent, they are not entirely trusted. This may be because they are not perceived to be friendly or warm.
Rusty-Patched bumble bee "re-discovered" in Virginia state park
October 4, 2014 08:45 AM - Smithsonian Science
The rusty-patched bumble bee (Bombus affinis), which has not been seen in the eastern United States in five years, has been found by a Smithsonian Conservation Biology Institute research team at Sky Meadows State Park in Delaplane, Va. This formerly common bee has disappeared from 87 percent of its range in the Upper Midwest and Eastern Seaboard and is feared headed for extinction. The research team, led by Bill McShea and Tom Akre of the Smithsonian Conservation Biology Institute and T'ai Roulston from the University of Virginia, surveyed bee populations at 17 Virginia sites from May through August to study the influence of land management on bee diversity. Only one individual of this now rare species was found among nearly 35,000 bees belonging to 126 species collected and examined by the study.
No longer able to find sea ice, walruses turn to land
October 2, 2014 09:24 AM - Morgan Erickson-Davis, MONGABAY.COM
A mass of thousands of walruses were spotted hauled up on land in northwest Alaska during NOAA aerial surveys earlier this week. An estimated 35,000 occupied a single beach — a record number illustrating a trend in an unnatural behavior scientists say is due to global warming. Walruses (Odobenus rosmarus)—iconic arctic mammals that are only distantly related to seals—traditionally use sea ice to rest, breed, and give birth, and as a vantage from which to spot mollusks and other food sources. However, as their habitat warms and sea ice melts, walruses are forced to come to land more often and in greater numbers.
Dog waste contaminates our waterways
October 1, 2014 10:50 AM - American Chemical Society
Americans love their dogs, but they don't always love to pick up after them. And that's a problem. Dog feces left on the ground wash into waterways, sometimes carrying bacteria — including antibiotic-resistant strains — that can make people sick. Now scientists have developed a new genetic test to figure out how much dogs are contributing to this health concern, according to a report in the ACS journal Environmental Science & Technology.
Yellowstone Aspen recovering thanks to the Wolves
October 1, 2014 08:47 AM - Oregon State University
Wildlife in Yellowstone National Park is undergoing dramatic shifts with consequences that are beginning to return the landscape to conditions not seen in nearly a century, according to a series of new studies. In the park's northeast section, elk have decreased in number in their historic winter range in the Lamar Valley and are now more numerous outside the park. This change in elk numbers and distribution can be traced back to the reintroduction of wolves in 1995-96. Scientists have hypothesized that wolves affect both the numbers and the behavior of elk, thereby reducing the impact of browsing on vegetation, a concept known as a "trophic cascade."
New research in Thailand finds birds and bats key to reforestation efforts
September 30, 2014 08:37 AM - Heather D'Angelo, MONGABAY.COM
Tropical forest restoration projects are exciting research sites for scientists studying factors that affect ecosystem recovery. Here, scientists are trying to understand plant community succession, i.e. the process of recovery after cleared lands are abandoned and allowed to regrow naturally. One of the most important components of this recovery process is seed dispersal, since seeds from nearby forests allow a deforested habitat to become populated again by native plants and trees.
Some good news for the oceans!
September 28, 2014 08:04 AM - Kevin Mathews, Care2
Good news for aquatic life: the oceans just got a little bit safer. Okay, so most of the ocean remains vulnerable to human devastation, but on Thursday, President Barack Obama used his authority to create the most massive ocean reserve in the world. In a single day, the amount of the world’s ocean protected from commercial interests has effectively doubled. Originally, the Pacific Remote Islands Marine National Monument was something that George W. Bush established during his last weeks in office. However, Obama has taken the symbolic ocean protection and turned it into something useful by growing the area to six times its original size.
Goats found to be better than chemicals when it comes to curbing invasive marsh grass
September 25, 2014 01:01 PM - Duke University via EurekAlert!
Herbivores, not herbicides, may be the most effective way to combat the spread of one of the most invasive plants now threatening East Coast salt marshes, a new Duke University-led study finds. Phragmites australis, or the common reed, is a rapid colonizer that has overrun many coastal wetlands from New England to the Southeast. A non-native perennial, it can form dense stands of grass up to 10 feet high that block valuable shoreline views of the water, kill off native grasses, and alter marsh function.
A new treaty to restore Buffalo herds and grazing land
September 24, 2014 01:29 PM - Wildlife Conservation Society
This week, dignitaries from U.S. Tribes and Canadian First Nations signed a treaty-the first among them in more than 150 years-to establish intertribal alliances for cooperation in the restoration of American buffalo (or bison) on Tribal/First Nations Reserves or co-managed lands within the U.S. and Canada. This historic signing of the "Northern Tribes Buffalo treaty" occurred in Blackfeet territory in Browning, Montana, and brought together members of the Blackfeet Nation, Blood Tribe, Siksika Nation, Piikani Nation, the Assiniboine and Gros Ventre Tribes of Fort Belknap Indian Reservation, the Assiniboine and Sioux Tribes of Fort Peck Indian Reservation, the Salish and Kootenai Tribes of the Confederated Salish and Kootenai Indian Reservation, and the Tsuu T’ina Nation.
Whooping Cranes being raised and released by the US Geological Survey
September 24, 2014 07:51 AM - USGS Newsroom
Four whooping crane chicks raised in captivity began their integration into the wild Saturday as part of the continuing effort to increase the wild population of this endangered species. The cranes, hatched and raised by their parents at the U.S. Geological Survey's Patuxent Wildlife Research Center in Laurel, Maryland, were released on the U.S. Fish and Wildlife Service's Necedah National Wildlife Refuge in Wisconsin.
