• Deadly Fungus Affecting Hibernating Bats Could Spread During Summer

    The cold-loving fungus (Pseudogymnoascus destructans, or Pd) that causes white-nose syndrome, a disease that has killed millions of North American bats during hibernation, could also spread in summer months. Bats and humans visiting contaminated caves and mines can inadvertently contribute to the spread of the fungus, according to a recently published study by the U.S. Geological Survey.

    USGS scientists tested samples collected from bats, the environment and equipment at eight bat hibernation sites in Kentucky, Indiana, Ohio, Tennessee and Virginia. They found that bats occupying such sites in summer can harbor the Pd fungus on their skin, and that Pd is more readily detectable in their guano, or feces.

  • A Dolphin Diet

    The health of dolphin populations worldwide depends on sustained access to robust food sources.

    A new report by UC Santa Barbara researchers and colleagues at UC San Diego and the National Oceanic and Atmospheric Administration looks at three different dolphin species, studying what they eat and how they divide ocean resources and space -- important information for conservation and management. The team's findings appear in the journal PLOS ONE.

    "We used the principle of 'you are what you eat' to unlock some of the secrets of dolphin diet," said lead author Hillary Young, an assistant professor in UCSB's Department of Ecology, Evolution, and Marine Biology (EEMB). "All of the foods that we or any animal eat are incorporated after digestion into body tissues. Most Americans, for example, chemically look like walking corn cobs because the foods we eat contain so much corn syrup."

  • Financial Incentives Could Conserve Tropical Forest Diversity

    The past few decades have seen the rise of global incentive programs offering payments to landowners to help reduce tropical deforestation. Until now, assessments of these programs have largely overlooked decreases in forest diversity. In what might be a first of its kind study, University of Missouri researchers have integrated forest imaging with field-level inventories and landowner surveys to assess the impact of conservation payments in Ecuador’s Amazon Basin forests. They found that conservation payment programs are making a difference in the diversity of tree species in protected spaces. Further, the species being protected are twice as likely to be of commercial timber value and at risk of extinction.

  • Loss of 350 miles of Great Plains streams causing changes in aquatic food web

    The food web in Great Plains streams could be unraveling, according to a Kansas State University ecologist.

    Keith Gido, professor of biology, and Josh Perkin, a Kansas State University alumnus, recently published "Groundwater declines are linked to changes in Great Plains stream fish assemblages" in the Proceedings of the National Academy of Sciences. The research maps the loss of stream habitat for many small fish in the Great Plains region and attributes it to declining groundwater sources.

  • Geoscientists explain puzzling pockets of rock deep in Earth's mantle

    A team led by geoscientists from Arizona State University and Michigan State University has used computer modeling to explain how pockets of mushy rock accumulate at the boundary between Earth's core and mantle.

  • Historical wildlife trends reliable for predicting species at risk

    Scientists at the University of York have shown that using historical wildlife data provides a more accurate measure of how vulnerable certain species might be to extinction from climate change.

    Some of the methods used to predict at risk species are trend-based – an indicator of what happens gradually over time – while others are trait based, which uses signs of climate change in the current environment.

  • Impact of giant Antarctic iceberg – update on Larsen-C

    The largest remaining ice shelf on the Antarctic Peninsula lost 10% of its area when an iceberg four times the size of London broke free earlier this month.

    Since the 12 July 2017 breakaway Dr Anna Hogg, from the University of Leeds, and Dr Hilmar Gudmundsson, from the British Antarctic Survey (BAS), have continued to track the iceberg – known as A68 – using the European Space Agency (ESA) and European Commission’s Copernicus Sentinel-1 satellite.

  • Wildfires Continue to Beleaguer Western Canada

    Like tourist season, wildfire season is also in full swing in British Columbia.  Whereas tourists are welcomed to the Canadian province, wildfires are not.  In British Columbia alone there are close to 500 wildfires active to date.  Most of these wildfires are located in three general areas--in the Caribou Fire Centre located in the Frasier Plateau directly north of Vancouver, in the Kamloops Fire Centre in the Thomas Plateau, which is east of Whistler, and the Southeast Fire Centre which is east of Kamloops.  All current fires of note can be viewed on this interactive map:  http://governmentofbc.maps.arcgis.com/apps/webappviewer/index.html?id=a1e7b1ecb1514974a9ca00bdbfffa3b1 

    Wildfires in British Columbia are common at this time of year due to rising temperatures, however, this year is the third worst year in the region for forest fires.  To date 840 fires have broken out since April 1 of this year.  Although it started slow, 2017 is shaping up to be a record breaking fire season if not for numbers of fires, then for the sheer amount of hectares burned.  In an area where rainfall is the norm, to have days and weeks without rainfall is unusual and helps to create a hot, dry environment with plenty of underbrush that fires use as fuel.

  • New NOAA Fisheries Research Reveals Ecosystem Cascades Affecting Salmon

    Interpreting relationships between species and their environments is crucial to inform ecosystem-based management (EBM), a priority for NOAA Fisheries. EBM recognizes the diverse interactions within an ecosystem — including human impacts — so NOAA Fisheries can consider resource tradeoffs that help protect and sustain productive ecosystems and the services they provide.
