• Lost ecosystem found buried in mud of southern California coastal waters

    Paleontologists investigating the sea bed off the coast of southern California have discovered a lost ecosystem that for thousands of years had nurtured communities of scallops and shelled marine organisms called brachiopods.

    These brachiopods and scallops had thrived along a section of coast stretching approximately 250 miles from San Diego to Santa Barbara for at least 4,000 years. But they had died off by the early 20th century, replaced by the mud-dwellling burrowing clams that inhabit this seabed today. Paleontologists Adam Tomašových of the Slovak Academy of Sciences and Susan Kidwell of the University of Chicago examine the lost ecosystem in a study published online June 7 in the Royal Society Proceedings B.

  • Great Lakes research centre provides state-of-the-art facility in LaSalle

    Students at the University of Windsor can now measure the stress levels of a pickerel swimming against a strong current, the turbidity of hazy tributaries feeding into the Great Lakes, and the behaviour of the invasive sea lamprey without wading into remote and distant waters.

    The Freshwater Restoration Ecology Centre in LaSalle is the only research facility of its kind in the Great Lakes Basin and provides students with state-of-the-art technology to study the restoration of damaged ecosystems, invasive species biology and water quality.

  • Scientists Discover New Species of Fijian Iguana

    Researchers from the U.S. Geological Survey, Taronga Conservation Society Australia, The National Trust of Fiji and NatureFiji-MareqetiViti have discovered a new species of banded iguana.

    The new species of lizard, Brachylophus gau, is one of only four living species of South Pacific iguana, and is restricted to the island of Gau, Republic of Fiji. The scientists describe this new addition in an article released with the journal Zootaxa.

  • Sahara greening intensify tropical cyclone activity worldwide

    Future climate warming could lead to a re-greening of the southernmost Sahara (Sahel), with decreased dust emissions and changes in land cover. In a recent study, researchers at the Department of Meteorology have found that tropical cyclone activity may have increased during past warm climates in connection with a greening of the Sahara.

  • Climate Change Misconceptions Common Among Teachers, Study Finds

    Recent studies have shown that misconceptions about climate change and the scientific studies that have addressed climate change are pervasive among the U.S. public. Now, a new study by Benjamin Herman, assistant professor in the Department of Learning, Teaching and Curriculum in the University of Missouri College of Education, shows that many secondary school science teachers also possess several of these same misconceptions.

  • Fungi awake bacteria from their slumber

    When a soil dries out, this has a negative impact on the activity of soil bacteria. Using an innovative combination of state-of-the-art analysis and imaging techniques, researchers at UFZ have now discovered that fungi increase the activity of bacteria in dry and nutrient-poor habitats by supplying them with water and nutrients. The ability of fungi to regulate drought stress in soil and thus sustain ecosystem functions is an important insight in the context of climate change.

  • Motor-boat noise makes fish bad parents, leading to the death of their babies

    Noise from motorboats is making fish become bad parents, and reducing the chance of their young surviving, research led by marine experts at the University of Exeter has shown.

    The sound of motorboat engines disturbed coral reef fish so acutely it changed the behaviour of parents, and stopped male fish properly guarding their young, feeding and interacting with their offspring.

  • Genetic study shakes up the elephant family tree

    New research reveals that a species of giant elephant that lived 1.5 million to 100,000 years ago – ranging across Eurasia before it went extinct – is more closely related to today’s African forest elephant than the forest elephant is to its nearest living relative, the African savanna elephant.

  • Why do Antarctic krill stocks fluctuate?

    It is only six centimetres long, but it plays a major role in the Antarctic ecosystem: the small crustacean Euphausia superba (Antarctic krill). It's one of the world's most abundant species and the central diet of a number of animals in the Southern Ocean. For a long time, scientists have been puzzled why the size of krill stocks fluctuates so widely. In a new study headed by Prof. Bernd Blasius and Prof. Bettina Meyer, a group of scientists from the University of Oldenburg's Institute for Chemistry and Biology of the Marine Environment (ICBM) and the Bremerhaven-based Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) have shown that the competition for food within the population is responsible for the variability.

  • Breeding pairs of birds cooperate to resist climate change

    Climate change causes ecological variation and affects the lives of animals. The ever-earlier springs and later autumns caused by rising temperatures cause changes to animals’ physiology, breeding seasons and even population distributions. However, little is still known about how animals behave in response to these disturbances.
