• Swarms of tiny oceanic organisms known collectively as zooplankton may have an outsize influence on their environment. New research at Stanford shows that clusters of centimeter-long individuals, each beating tiny feathered legs, can, in aggregate, create powerful currents that may mix water over hundreds of meters in depth.

  • Thanks to mom and dad, baby reef fish may have what it takes to adjust to hotter oceans.

    In a rapidly changing climate, the decline of animal populations is a very real concern. Today, an international team of researchers report new evidence of reef fish adjusting to global warming conditions at the genetic level.

  • More than 70 years after the end of the Second World War, countless pieces of ammunition from this time are still lying – and corroding – in all oceans. Once the casings are damaged, the explosives can release toxic substances into the seawater. A new review study, published by scientists from the GEOMAR Helmholtz Centre for Ocean Research Kiel and the Schleswig-Holstein Ministry of the Environment in the journal Frontiers in Marine Science, points to considerable knowledge gaps regarding the spread and effects of these chemicals on marine ecosystems.

  • It’s not easy to catch an Egyptian vulture.

    Evan Buechley knows. He’s hunkered down near garbage dumps from Ethiopia to Armenia, waiting for the highly intelligent birds to trigger a harmless trap. But no matter how well he and other researchers hid the traps, he says, “somehow the birds could always sense that something was up.”

  • Drop an electric motor into a ship and you’re all set to sail into a cleaner environment, right?

    If only it were that simple, says a University of Victoria mechanical engineer whose research focuses on hybrid electric propulsion systems.

  • Last year, University of British Columbia zoologist Wayne Maddison travelled to the highlands of southern Mexico in pursuit of undiscovered species of jumping spiders. He kept a journal of his adventures, documenting his encounters with resplendently beautiful arachnids.

  • NOAA scientist Carol Stepien will present research results at a public forum this week in Toledo, Ohio, on how local bait shops, anglers and the public can prevent invasive fish from accidentally being released into the Great Lakes.

  • A population of exotic invasive Cuban treefrogs has been discovered in New Orleans, more than 430 miles (700 kilometers) from the nearest known population in Florida, making this the first known breeding population in the mainland United States outside that state, reports a new study by the U.S. Geological Survey.

  • Nitrogen is essential to marine life and cycles throughout the ocean in a delicately balanced system. Living organisms—especially marine plants called phytoplankton—require nitrogen in processes such as photosynthesis. In turn, phytoplankton growth takes up carbon dioxide from the atmosphere and helps regulate global climate.

  • Primatologist Jane Goodall came to the University of Toronto over the weekend to mark Earth Day with a discussion about her life, work and the need to protect the planet.
