Scientists studying data from the top of the Greenland ice sheet have discovered that during winter, temperature inversions and other low-level atmospheric phenomena effectively isolate the ice surface from the atmosphere -- recycling water vapor and halting the loss or gain of ice.
Dr. Michael Steinberg, a University of Alabama associate professor in New College and geography, is conducting a study of the coastal mangrove forests in Cuba’s Zapata Peninsula and the Jardines de la Reina Garden of the Queen Marine Reserve national parks. The study is using satellite maps of the park’s coastal mangrove forests from the past 20 years to examine the forests growth or decline during that time frame. The mangrove forests of Cuba are important because they provide natural habitat for many species of aquatic fish, crabs and shrimp. They also serve as homes for migratory birds and stabilize the coast from waves, tides and tsunamis. Without them, coastal erosion would occur. The study is the first cooperate conservation mapping project between Cuba and the U.S. since the Cuban embargo.
With only three living individuals left on this planet, the northern white rhinoceros could be considered doomed for extinction. But now researchers have proposed a road map for preserving such endangered species through techniques that use stem cells and assisted reproduction technology.
Current estimates of the number of cheetahs in the wild are 'guesswork', say the authors of a new study which finds that the population in the cheetah stronghold of Maasai Mara, Kenya, is lower than previously thought.
The American Association of Occupational Health Nurses is pleased to announce the AAOHN 2017 National Conference, April 24-27, 2017, in New Orleans, La., where the theme will be “History, Passion, Performance: Together Towards Tomorrow.”
The Royal Entomological Society has awarded its 2016 Best Paper Award to a paper written by University of Florida Institute of Food and Agricultural Sciences researchers. Lukasz Stelinski, an associate professor of entomology at the UF/IFAS Citrus Research and Education Center, spearheaded the study in which investigators came up with a synthetic aroma to lure redbay ambrosia beetles into traps. “Identifying an effective lure for the beetle is an important step in developing management tools for this pathogen-spreading insect in Florida,” Stelinksi said.
Robert Manning, a natural resources professor at the University of Vermont, has conducted research for the National Park Service for 35 years and is the co-editor of a thoughtful book of essays on the national parks. He would provide wide-ranging perspective for stories pegged to the 100th anniversary of the National Park Service.
A combination of drought and fire has put the Arizona black rattlesnake on an “extinction trajectory,” according to University of Arkansas researchers.
Twenty years ago, there were only two species of mouse lemurs. Today, including the newly-discovered species, mouse lemurs comprise 24 species. According to the International Union for Conservation of Nature's Red List, 94 percent of lemurs are threatened with extinction.
Earth could contain nearly 1 trillion species, with only one-thousandth of 1 percent now identified, according to a study from biologists at Indiana University. The estimate, based on the intersection of large datasets and universal scaling laws, appears today in the Proceedings of the National Academy of Sciences.
Global Food Summit: Sustainable Solutions is the second of a two-part Global Food Security conference held at University of California, Irvine.

As world leaders convene in Washington, DC this week for the Climate Action 2016 summit, a new report by Maryland public health leaders, the Maryland Climate and Health Profile report, details the impacts of climate change on the health of Marylanders now and in the future.
A group of researchers concluded today in a study in the journal BioScience that "hydropeaking" of water flows on many rivers in the West has a devastating impact on aquatic insect abundance.
In a new study, University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science researchers found that the limestone that forms the foundation of coral reefs along the Florida Reef Tract is dissolving during the fall and winter months on many reefs in the Florida Keys. The research showed that the upper Florida Keys were the most impacted by the annual loss of reef.
An analysis of more than 40 climate-adaptation plans from across the U.S. shows that local communities are good at developing strategies to combat the harmful effects of climate change but often fail to prioritize their goals or to provide implementation details.
Scientists have found that rain triggers the release of a mist of particles from wet soils into the air, a finding with consequences for how scientists model our planet’s climate and future. The evidence comes in the form of tiny glassy spheres, less than one-hundredth the width of a human hair, discovered in the Great Plains.
The lady salamander that shuns male companionship may reap important benefits.
For instance, when a predator snaps off her tail. New research from The Ohio State University compared an all-female population of mole salamanders to a related heterosexual species and found they grew their tails back 36 percent faster. The unisexual salamanders (part of the Ambystoma genus) contain DNA of up to five species and reproduce primarily by cloning themselves.
