  • Rising Temperatures Threaten Stability of Tibetan Alpine Grasslands

    A warming climate could affect the stability of alpine grasslands in Asia’s Tibetan Plateau, threatening the ability of farmers and herders to maintain the animals that are key to their existence, and potentially upsetting the ecology of an area in which important regional river systems originate, says a new study by researchers in China and the United States.

  • EPA Asked to Reject Expanded Use of Medically Important Antibiotic on Citrus Crops

    The Center for Biological Diversity and Johns Hopkins Center for a Livable Future today asked the Environmental Protection Agency to reject a pesticide company’s request to permanently approve the use of a medically important antibiotic called oxytetracycline as a herbicide on citrus crops.

  • MIT researchers develop new way to clear pollutants from water

    When it comes to removing very dilute concentrations of pollutants from water, existing separation methods tend to be energy- and chemical-intensive. Now, a new method developed at MIT could provide a selective alternative for removing even extremely low levels of unwanted compounds.

  • Neonic Pesticides Threaten Wild Bees' Breeding: Study

    Neonicotinoid pesticides hinder wild queen bumblebees’ reproductive success, according to a new University of Guelph study.

    The study is the first to link exposure to thiamethoxam — one of the most commonly used neonicotinoid pesticides — to fewer fully developed eggs in queens from four wild bumblebee species that forage in farmland.

  • All the Trees Will Die, and Then So Will You

    The Polyphagous shot hole borer, a brown-black beetle from southeast Asia, never gets bigger than a tenth of an inch. It breeds inside trees; pregnant females drill into trunks to create networks of tunnels where they lay their eggs. The beetles also carry a fungus called Fusarium; it infects the tunnels, and when the eggs hatch, the borer larvae eat the fungus.

  • Tillage farming damaging earthworm populations, say scientists

    The digging, stirring and overturning of soil by conventional ploughing in tillage farming is severely damaging earthworm populations around the world, say scientists.

  • Migrating mule deer track green waves of spring forage

    Migratory mule deer in Wyoming closely time their movements to track the spring green-up, providing evidence of an underappreciated foraging benefit of migration, according to a study by University of Wyoming and U.S. Geological Survey scientists at the Wyoming Cooperative Fish and Wildlife Research Unit.

  • Leaf litter has slower decomposition rate in warm temperatures than previously thought

    The time it takes for a leaf to decompose might be the key to understanding how temperature affects ecosystems, according to Kansas State University ecologists.

  • Scientists track porpoises to assess impact of offshore wind farms

    A new study by scientists at the University of Maryland Center for Environmental Science’s Chesapeake Biological Laboratory, Cornell University and Duke University is the first in a series to understand how marine mammals like porpoises, whales, and dolphins may be affected by the construction of wind farms off the coast of Maryland. The new research offers insight into previously unknown habits of harbor porpoises in the Maryland Wind Energy Area, a 125-square-mile area off the coast of Ocean City that may be the nation’s first commercial-scale offshore wind farm.

  • Wind Turbines Affect Behavior of Desert Tortoise Predators

    How a wind energy facility is designed can influence the behavior of animal predators and their prey, according to a recent study published in The Journal of Wildlife Management by researchers at the University of California, Davis, and the U.S. Geological Survey.

    Scientists placed motion-activated cameras facing the entrances of 46 active desert tortoise burrows in a wind energy facility near Palm Springs, California. Video recordings showed that visits to burrows from five predators -- bobcats, gray foxes, coyotes, black bears and western spotted skunks -- increased closer to dirt roads, and decreased closer to wind turbines.
