Poor outlook for biodiversity in Antarctica

Wed, 29 Mar 2017 09:16:06 EDT ~ The popular view that Antarctica and the Southern Ocean are in a much better environmental shape than the rest of the world has been brought into question in a new study. Find out more...

Seasonal warming leads to smaller animal body sizes

Tue, 28 Mar 2017 19:06:43 EDT ~ Changes in the body size of animals measured under controlled laboratory conditions have been shown to closely match changes in body size with seasonal warming in nature, according to research. Find out more...

Polar fronts oceanographic barrier is not as impermeable for bryozoans of the Southern Ocean as thought

Fri, 24 Mar 2017 10:55:20 EDT ~ The polar front, an oceanographic barrier between the Austral Ocean and its surrounding water masses, is not the impermeable biogeograpgical barrier it was thought to be, according to a new article. Find out more...

Evolutionary advantage of the common periwinkle

Fri, 24 Mar 2017 10:48:45 EDT ~ A special kind of small sulfur-rich proteins, the metallothioneins, have an extraordinarily large capability for binding heavy metals. An international team of scientists has now discovered that the marine common periwinkle, which is widely considered a delicacy, contains the largest version of the protein found yet, with one additional cadmium-binding domain and a one-third higher detoxification capacity. This feature may help the snail survive in heavy-metal-polluted environments. Find out more...

Climate change and an 'overlooked' nutrient: Silica

Thu, 23 Mar 2017 12:55:19 EDT ~ Sugar maples may have far greater silica pumping power than expected, and also may be more profoundly affected by climate change as warmer winters damage their vulnerable roots. Find out more...

Corals die as global warming collides with local weather in the South China Sea

Thu, 23 Mar 2017 10:58:24 EDT ~ In the South China Sea, a 2C rise in the sea surface temperature in June 2015 was amplified to produce a 6C rise on Dongsha Atoll, a shallow coral reef ecosystem, killing approximately 40 percent of the resident coral community within weeks, according to a study.

Sea urchin spines could fix bones

Wed, 22 Mar 2017 10:37:14 EDT ~ More than 2 million procedures every year take place around the world to heal bone fractures and defects from trauma or disease, making bone the second most commonly transplanted tissue after blood. To help improve the outcomes of these surgeries, scientists have developed a new grafting material from sea urchin spines. Find out more...

Salmon with side effects: Aquacultures are polluting Chile's rivers with a cocktail of dissolved organic substances

Wed, 22 Mar 2017 09:45:20 EDT ~ Tasty, versatile, and rich in essential omega-3 fatty acids: salmon is one of the most popular edible fish of all. Shops sell fish caught in the wild, but their main produce is salmon from breeding farms which can pollute rivers, lakes and oceans. Just how big is the problem? Scientists are working to answer this question by examining the dissolved organic compounds which enter Chiles rivers from salmon farms. They warn that these substances are placing huge strain on ecosystems and are changing entire biological communities. Find out more...

430 million-year-old fossil named in honor of Sir David Attenborough

Wed, 22 Mar 2017 09:23:43 EDT ~ A new 430 million-year-old fossil has been discovered by scientists, and has been named in honor of Sir David Attenborough. The discovery is a unique example of its kind in the fossil record, say the authors of a new report. Find out more...

A new species of hard coral from the World Heritage-listed Lord Howe Island, Australia

Wed, 22 Mar 2017 09:20:18 EDT ~ The discovery of a new species of hard coral, found on Lord Howe Island, suggests that the fauna of this isolated location in the Tasman Sea off south eastern Australia is even more distinct than previously recognized. Even though the World Heritage-listed site has been long known for its biodiversity, the new species is the first coral known to live exclusively in the region. Find out more...
