• UA Researchers discover the most abundant viruses in all the Earth's oceans

    A group of scientists from several research centres and international universities led by Manuel Martínez García, from the University of Alicante Research Group in Molecular Microbian Ecology has discovered forty-four of the most abundant new viruses in all the Earth's oceans. The finding has been achieved thanks to the application of cutting-edge techniques that mix flow cytometry and genomics and molecular biology techniques. The findings will appear today, 23 June 2017, in the scientific journal Nature Communications.

  • NASA Detects Drop in Global Fires

    Shifting livelihoods across the tropical forest frontiers of South America, the Eurasian Steppe, and the savannas of Africa are altering landscapes and leading to a significant decline in the amount of land burned by fire each year, a trend that NASA satellites have detected from space.

    The ongoing transition from nomadic cultures to settled lifestyles and intensifying agriculture has led to a steep drop not only in the use of fire on local lands, but in the prevalence of fire worldwide, researchers at NASA's Goddard Space Flight Center in Greenbelt, Maryland, and colleagues found.

  • More Milkweeds Located Throughout the Landscape Can Help Conserve Monarchs

    Adding milkweeds and other native flowering plants into midwestern agricultural lands is key to restoring monarch butterflies, with milkweed sowers from all sectors of society being critically needed for success.

  • Bumble bees make a beeline for larger flowers

    Bumble bees create foraging routes by using their experience to select nectar-rich, high-rewarding flowers. A study by Shohei Tsujimoto and Hiroshi Ishii of the University of Toyama in Japan now suggests that bees actually forage more efficiently when flower sizes are large rather than small. This indicates that for these insect pollinators foraging quickly is more efficient than foraging accurately. The research is published in Springer’s journal Behavioral Ecology and Sociobiology and uses a laboratory-based experiment to investigate how aspects of associative learning influence how bumble bees find food among different-sized flowers.

  • Canada +150: DNA Barcodes — Sci-Fi Tech to Safeguard Environment

    A Canadian technology that can identify a substance by scanning it — as a character in Star Trek might — could become a crucial tool to capture DNA data in the environment and protect it.

    DNA barcoding, developed at the University of Guelph by Professor Paul Hebert, uses genetic variations to identify different species. It’s similar to how a supermarket checkout scanner reads variations in a UPC barcode’s lines to identify a product you buy.

  • Fish living in extreme environments adapt ability to see

    Cell biologists at the University of Toronto have discovered animals can adapt their ability to see even with extreme changes in temperature.

    The researchers looked deeply into the eyes of catfish living in cold-water streams at altitudes of up to nearly three kilometres in the Andes Mountains to find out how. Their findings are published in Proceedings of the National Academy of Sciences.

  • Lake Harvests are Likely More Fruitful than We Knew

    Harvests from freshwater fisheries such as the Great Lakes could total more than 12 million tons a year globally and contribute more to global food supplies and economies than previous estimates indicate, according to a study published today by Michigan State University and the U.S. Geological Survey.

  • How grassland management without the loss of species works

    The intensive management of grasslands is bad for biodiversity. However, a study by the Terrestrial Ecology Research Group at the Technical University of Munich (TUM) has brought a ray of hope: If different forms of management are optimally distributed within a region, this can lead to higher yields without the loss of insect species. In ideal cases, this will allow even more species to find habitats that are optimal for them. What is crucial here is that management is planned at the landscape level.

  • The Dust Storm Microbiome

    Israel is subjected to sand and dust storms from several directions: northeast from the Sahara, northwest from Saudi Arabia and southwest from the desert regions of Syria. The airborne dust carried in these storms affects the health of people and ecosystems alike. New research at the Weizmann Institute of Science suggests that part of the effect might not be in the particles of dust but rather in bacteria that cling to them, traveling many kilometers in the air with the storms.

  • Septic systems are a major source of emerging contaminants in drinking water

    A new analysis shows that septic systems in the United States routinely discharge pharmaceuticals, consumer product chemicals, and other potentially hazardous chemicals into the environment. The study, published June 15 in the journal Environmental Science & Technology, is the most comprehensive assessment to date of septic systems as important sources of emerging contaminants, raising health concerns since many of these chemicals, once discharged, end up in groundwater and drinking water supplies.

    Known as contaminants of emerging concern (CECs), these types of pollutants are frequently detected in U.S. rivers, lakes, and drinking water supplies. However, the U.S. Environmental Protection Agency does not currently regulate them in drinking water. Many emerging contaminants are hormone disruptors.
