Researchers from FSU's Department of Earth, Ocean and Atmospheric Science suggest that projected increases in air temperatures, rainfall inundation and blistering solar radiation could significantly reduce hawksbill hatching success at a selection of major nesting beaches.
Hundreds of dams are being proposed for Mekong River basin in Southeast Asia. The negative social and environmental consequences -- affecting everything from food security to the environment -- greatly outweigh the positive changes of this grand-scale flood control, according to new research by Michigan State University.
Team praises widespread commitment but calls for broader participation to better protect global marine ecosystems.
Four growing seasons after the engineered spring flood of the Colorado River Delta in March 2014, the delta's birds, plants and groundwater continue to benefit. The diversity and abundance of birds of special conservation concern remains high in the restoration sites, groundwater was recharged and some of the trees are now more than 14 feet (4.2 meters) tall, according to an International Boundary and Water Commission report prepared by a University of Arizona-led team.
Medical University of Vienna professor Leopold Eckhart and colleagues have performed one of the largest comparative genomic studies to help determine the key molecular and evolutionary origins of mammalian adaptations seen in skin proteins. "The results of the present study provide important new data on the evolution of keratins that control the mechanical stability of the epidermis, the outermost layer of the skin," said Eckhart.
Researchers at the Salk Institute report which genes are turned on or off, and in which order, to orchestrate the cellular processes required to protect and repair the genome in response to DNA damage. The research, appearing in PNAS, reveals the genetic framework controlling a complex biological process that has broad implications for understanding how plants in particular, and organisms in general, cope with DNA damage to ensure long-term health and fitness.
When humans experience stress, their inner turmoil may not be apparent to an outside observer. But many animals deal with stressful circumstances -- overcrowded conditions, not enough food -- by completely remodeling their bodies. These stress-induced forms, whether they offer a protective covering or more camouflaged coloration, can better withstand the challenge and help the animal survive until conditions improve.
Researchers have developed genetically modified pigs that are protected from classical swine fever virus (CSFV), according to a study published December 13 in the open-access journal PLOS Pathogens by Hongsheng Ouyang of Jilin University, and colleagues. As noted by the authors, these pigs offer potential benefits over commercial vaccination and could reduce economic losses related to classical swine fever.
Michigan State University scholar Andrea Glassmire and her colleagues have revealed how the mixture of chemical weapons deployed by plants keeps marauding insects off base better than a one-note defense. This insight goes beyond the ecological convention of studying a single chemical compound a plant is packing and offers new ways to approach agricultural pest management. The research was published in today's Ecology Letters.
A new study shows that fecal bacteria from sewage are living in far greater quantities in near-shore sediments of the Hudson River than in the water itself. The river's pollution levels are generally monitored based on samples of clear water, not sediments, so the findings suggest that people stirring up the bottom while wading, swimming or kayaking may face previously unrecognized health risks.
