Long-term research reveals how climate change is playing out in real ecosystems Around the world, the effects of global climate change are increasingly evident and difficult to ignore. However, evaluations of the local effects of climate change are often confounded by natural and human induced factors that overshadow the effects of changes in climate on ecosystems. Now, a group of scientists writing in the journal BioScience report a number of surprising results that may shed more light on the complex nature of climate change.

Making sustainability policies sustainable Sweeping environmental policies come with hidden challenges -- not only striving to achieve sustainability and benefit the environment -- but over time ensuring the program itself can endure. Scientists at Michigan State University and their colleagues in China are examining China's massive Grain to Green Program -- an effort to persuade farmers to return cropland to forest through financial incentives. Their results were reported in this week's journal Ecological Indicators. Contact: Sue Nichols Public Release: 30-Nov-2012

How native plants and exotics coexist Exotic plants in many ecosystems may be better competitors, but in a study in Ecology Letters researchers at Winthrop University and Brown University found that exotics can be kept in check by herbivory. Contact: David Orenstein Public Release: 30-Nov-2012
People not hooked on fish could get omega-3 through fortified milk Food science researchers at Virginia Tech may have reeled milk into the fish oil delivery system, showing it is possible to incorporate omega-3 fatty acids into milk and dairy-based beverages in amounts sufficient to promote heart health, without destroying the milk's taste. The innovation may be a way to help people who do not eat fish get some of the heart-healthy benefits of fish oil. Contact: John Pastor Public Release: 30-Nov-2012
A digital portrait for grapes indicates their ripeness Researchers at the University of Seville (Spain) have developed a technique for estimating grape composition and variety using computer imaging. They have also put forward an index for identifying the ripeness of seeds without the need for chemical analysis. This new method can help to decide the best moment for picking.

The colour of love: Zebrafish perform colorful courtship displays Billy Ocean may not have been thinking of fish when he wrote "The Color of Love", but Sophie Hutter, Attila Hettyey, Dustin Penn, and Sarah Zala from the Konrad Lorenz Institute of Ethology of the University of Veterinary Medicine, Vienna were able to show that zebrafish males and females both wear their brightest colors while wooing a mate.

Garbage bug may help lower the cost of biofuel One reason that biofuels are expensive to make is that the organisms used to ferment the biomass cannot make effective use of hemicellulose, the next most abundant cell wall component after cellulose. They convert only the glucose in the cellulose, thus using less than half of the available plant material. University of Illinois researchers have been doing research at the Energy Biosciences Institute on an organism that they think could be used to solve this problem.

Birds may spread, not halt, fever-bearing ticks Turkey raises and releases thousands of non-native guineafowl to eat ticks that carry the deadly Crimean-Congo hemorrhagic fever virus. Yet research suggests guineafowl eat few ticks, but carry the parasites on their feathers, possibly spreading the disease they were meant to stop, says a Turkish biologist working at the University of Utah.

Sources of E. coli are not always what they seem US Department of Agriculture scientists have identified sources of Escherichia coli bacteria that could help restore the reputation of local livestock. Studies by scientist Mark Ibekwe suggest that in some parts of California, pathogens in local waterways are more often carried there via runoff from urban areas, not from animal production facilities.

Insects beware: The sea anemone is coming Insects are becoming resistant to insecticides, presenting a growing need to develop novel ways of pest control. New research in The FASEB Journal shows that the sea anemone's venom harbors toxins that could pose a new generation of environmentally friendly insecticides, which avoid insect resistance. These toxins disable ion channels that mediate pain and inflammation, and could also spur drug development aimed at pain, cardiac disorders, epilepsy and seizure disorders, and immunological diseases.

An ocean away: 2 new encrusting anemones found in unexpected locations A group of marine biologists from Japan has discovered two new species of encrusting anemone, thousands of kilometres away from the single other known species of the group. The first species from Madagascar was found in 1972 and never reported again, while the new species are from the Great Barrier Reef in Australia and southern Japan. The study was published in the open access journal ZooKeys. Contact: James D. Reimer Public Release: 29-Nov-2012
University of Tennessee engineering professor looks to whirligig beetle for bio-inspired robots While many may have found the movements of whirligig beetles curious, scientists have puzzled over the apparatus behind their energy efficiency -- until now, thanks to a study performed by a team led by Mingjun Zhang, associate professor of mechanical, aerospace and biomedical engineering, at the University of Tennessee, Knoxville.

New study shows how climate change could affect entire forest ecosystems The fog comes in, and a drop of water forms on a pine needle, rolls down the needle, and falls to the forest floor. The process is repeated over and over, on each pine needle of every tree in a forest of Bishop pines on Santa Cruz Island, off the coast of Santa Barbara. That fog drip helps the entire forest ecosystem stay alive. Contact: Gail Gallessich Public Release: 28-Nov-2012
Scientists sniff out the substances behind the aroma in the 'king of fruits' The latest effort to decipher the unique aroma signature of the durian -- revered as the "king of fruits" in southeast Asia but reviled elsewhere as the world's foulest smelling food -- has uncovered several new substances that contribute to the fragrance. The research appears in ACS' Journal of Agricultural and Food Chemistry. Contact: Michael Bernstein Public Release: 28-Nov-2012

Tiny algae shed light on photosynthesis as a dynamic property Many of the world's most important photosynthetic eukaryotes such as plants got their light-harnessing organelles (chloroplasts) indirectly from other organisms through endosymbiosis. In some instances, this resulted in algae with multiple, distinct genomes, some in residual organelles (nucleomorphs). To better understand why nucleomorphs persist after endosymbiosis, an international team including researchers at the DOE Joint Genome Institute collaborated to sequence and analyze two tiny algae. Their report appeared online Nov. 29, 2012 in Nature. Contact: David Gilbert |
