  • News about a plant hormone
    on December 7, 2018 at 4:27 pm

    The plant hormone jasmonic acid also performs a function that was previously unknown. It ensures that the leaf pores close when leaves are injured. For the plant, this could be an emergency signal. […]

  • Snowpack declines may stunt tree growth and forests' ability to store carbon emissions
    on December 1, 2018 at 5:06 pm

    Researchers conducting a 5-year-long study examining snow cover in a northern hardwood forest region found that projected changes in climate could lead to a 95 percent reduction of deep-insulating snowpack in forest areas across the northeastern United States by the end of the 21st century. The loss of snowpack would likely result in a steep reduction of forests' ability to store climate-changing carbon dioxide and filter pollutants from the air and water. […]

  • Historical climate important for soil responses to future climate change
    on November 30, 2018 at 2:43 pm

    Researchers examined how 18 years of drought affect the billions of vital bacteria that are hidden in the soil beneath our feet. The results show that this type of extreme weather determines how soils respond to future climate change. […]

  • For arid, Mars-like Peruvian desert, rain brings death
    on November 14, 2018 at 7:43 pm

    When rains fell on the arid Atacama Desert, it was reasonable to expect floral blooms to follow. Instead, the water brought death. Planetary astrobiologists has found that after encountering never-before-seen rainfall three years ago at the arid core of Peru's Atacama Desert, the heavy precipitation wiped out most of the microbes that had lived there. […]

  • Availability of nitrogen to plants is declining as climate warms
    on October 22, 2018 at 5:57 pm

    Researchers have found that global changes, including warming temperatures and increased levels of carbon dioxide in the atmosphere, are causing a decrease in the availability of a key nutrient for terrestrial plants. This could affect the ability of forests to absorb carbon dioxide from the atmosphere and reduce the amount of nutrients available for the creatures that eat them. […]

  • Genetic basis for how harmful algae blooms become toxic
    on September 28, 2018 at 5:13 pm

    Scientists have uncovered the genetic basis for the production of domoic acid, a potent neurotoxin produced by certain harmful algae blooms. […]

  • New, highly stable catalyst may help turn water into fuel
    on September 28, 2018 at 5:13 pm

    Breaking the bonds between oxygen and hydrogen in water could be a key to the creation of hydrogen in a sustainable manner, but finding an economically viable technique for this has proved difficult. Researchers report a new hydrogen-generating catalyst that clears many of the obstacles -- abundance, stability in acid conditions and efficiency. […]

  • Weathering rates for mined lands exponentially higher than unmined sites
    on September 25, 2018 at 6:04 pm

    A new study found a dramatic increase in the chemical weathering rates of mined landscapes, which are melting away bedrock up to 45 times faster than unmined areas. The weathering has global consequences for the cycling of sulfur, a key nutrient for all life forms. […]

    on September 19, 2018 at 3:58 pm

    The amount of carbon dioxide released from thawing permafrost might be greater than previously thought, according to a new study by ecologists. The research is the first to document the potential for substantial contributions of CO2 from thawing permafrost to the atmosphere through an inorganic process called mineral weathering. […]

  • California: Global warming, El Niño could cause wetter winters, drier conditions in other months
    on September 4, 2018 at 7:04 pm

    New research indicates that what future precipitation California gets will be pretty much limited to the winter months -- think deluge-type rainfall rather than snow -- and non-winter months will be even dryer than usual, with little or no rain at all. […]

  • Ancient African herders had lasting ecological impact on grazed lands
    on August 29, 2018 at 5:32 pm

    Ancient animal herders added to the ecological richness and diversity of the African savanna thousands of years ago -- an effect that persists to the present day, a new study finds. The herders' practice of penning their cattle, goats and sheep at night created nutrient-rich grassy glades that still attract wildlife and have increased habitat diversity in the region, researchers report. […]

  • Invasive plants: Scientists examine the relative impact of proximity to seed sources
    on August 17, 2018 at 4:53 pm

    A new study tackles an important, unresolved question in the biology of invasive plants. Which is most important to the establishment of new invasive communities -- proximity to seed sources, canopy disturbance, or soil disturbance? […]

    on August 10, 2018 at 1:15 pm

    There are many factors that play a role in whether or not it rains, and new research shows that human activity may be one of them. […]

  • Rain-on-snow flood risk to increase in many mountain regions of the western U.S., Canada
    on August 6, 2018 at 8:27 pm

    Flooding caused by rain falling on snowpack could more than double by the end of this century in some areas of the western United States and Canada due to climate change. […]

  • Wetter soil is leading to reduced methane gas absorption
    on August 6, 2018 at 7:20 pm

    A new paper finds that the existing effects of global warming are decreasing the soil's ability to absorb methane gas. The paper details findings from a study that measured forest-soil uptake of methane gas in a variety of locations and settings over a 13- to 27-year span and detected decreases of 53 to 89 percent. […]

  • Soil phosphorus availability and lime: More than just pH?
    on August 1, 2018 at 12:40 pm

    Plants can't do without phosphorus. But there is often a 'withdrawal limit' on how much phosphorus they can get from the soil. A new study looks at how liming, soil management history and enzymes relate to plants' access to phosphorus. […]

  • Why eastern U.S. air pollution levels are more stagnant in winter
    on July 23, 2018 at 7:25 pm

  • Reining in soil's nitrogen chemistry
    on July 11, 2018 at 4:24 pm

    The compound urea is currently the most popular nitrogen soil fertilizer. It's a way to get plants the nitrogen they need to grow. There's just one problem with urease: it works too well! New research suggests farmers may have a choice in how they slow the release of nitrogen, depending on their soil's acidity. […]

  • Dust carried by rainwater across Texas: Study sheds light on composition
    on July 10, 2018 at 12:29 am

    Across the US Southwest, severe drought and land?use change are projected to increase in the future, contributing to more frequent and intense dust storms and eventually dry dust fallout and dust washout from the atmosphere with rain. How will Dust Bowl-like conditions affect raining dust events? […]

  • Utah soil's slippery grip on nutrients
    on July 2, 2018 at 6:56 pm

    Lawns in the Salt Lake Valley up to 100 years old are not yet saturated in the nutrient nitrogen, which is added by fertilizer, according to a new study. The result is surprising, since previous studies in the Eastern US suggested that fertilized soil would become saturated with nitrogen within a few decades. […]

  • Simple chemical process that may have led to the origin of life on Earth
    on June 13, 2018 at 2:19 pm

    Research has shown that reactions of alpha-hydroxy acids, similar to the alpha-amino acids that make up modern proteins, form large polymers easily under conditions presumed prevalent on early Earth. These alpha-hydroxy acid polymers may have aided in the formation of living systems on early Earth. […]

  • Surprising resurgence of red spruce likely result of cleaner air and warmer winters
    on June 5, 2018 at 4:08 pm

    When scientists found a resurgence of red spruce in northeastern forests, they had a lot of questions. Fifty years ago, red spruce was the equivalent of a canary in the coalmine signaling the effects of acid rain on forests. Researchers have identified two factors behind the tree's surprising recovery: reduced inputs of acid rain and warmer fall, winter and spring temperatures. […]
