Penguins, starfish, whales: Which animals will win and lose in a warming Antarctic?

Thu, 17 Jan 2019 09:05:04 EST ~ Using risk assessments, like those used for setting occupational safety limits in the workplace, researchers determined the winners and losers of climate change in the Antarctic. They show that marine animals associated with sea ice for food or breeding, such as some whales and penguins, are most at risk from the effects of climate change, while seafloor predators and open-water feeding animals like starfish and jellyfish will benefit from the opening up of new habitat.

Emperor penguins' first journey to sea

Thu, 17 Jan 2019 09:04:41 EST ~ New research reveals the previously unknown behaviors of juvenile Emperor penguins in their critical early months when they leave their birth colony and first learn how to swim, dive, and find food. Find out more...

Full carbonate chemistry at the site of calcification in a tropical coral

Wed, 16 Jan 2019 15:06:27 EST ~ Researchers have succeeded in directly measuring three key parameters necessary for skeleton formation in a live tropical coral. This way, they completely characterized the carbonate chemistry at the site of calcification. Find out more...

Marine mammals and sea turtles recovering after Endangered Species Act protection

Wed, 16 Jan 2019 14:06:26 EST ~ More than three-quarters of marine mammal and sea turtle populations have significantly increased after listing of the US Endangered Species Act (ESA), according to a new study. Find out more...

Jellyfish map could be the future to protecting UK waters and fish

Wed, 16 Jan 2019 11:10:42 EST ~ Researchers have developed a map of chemicals found in jellyfish caught across 1 million square kilometers of UK waters. The same chemicals are found in other marine animals such as birds and fish. These findings can support conservation efforts by helping track an animals movements and also be used as a tool to detect food fraud by identifying where seafood products were sourced from.

Coralline red algae have existed for 300 million years longer than presumed

Wed, 16 Jan 2019 11:10:08 EST ~ Coralline red algae have existed for 130 million years, in other words since the Cretaceous Period, the time of the dinosaurs. At least this was the established view of palaeontologists all over the world until now. However, this classification will now have to be revised after fossils prove that coralline red algae existed as far back as 430 million years ago. Find out more...

Ocean giant gets a health check: Combination blood, tissue test reveals whale shark diets

Wed, 16 Jan 2019 09:06:36 EST ~ Whale sharks, the world's largest fish, likely endure periods of starvation and may eat more plants than previously thought, according to the first results of a new health check. Ocean scientists now have a powerful, simple tool to discover the diets, migrations, and conservation needs of this endangered species. Find out more...

New conservation practice could reduce nitrogen pollution in agricultural drainage water

Tue, 15 Jan 2019 16:23:09 EST ~ In a new study, scientists have estimated that a new conservation practice known as saturated buffers could reduce nitrogen from agricultural drainage by 5 to 10 percent. Find out more...

Black mangroves' impact on the salt marsh food web

Tue, 15 Jan 2019 13:29:07 EST ~ Warmer temperatures are causing more tropical species to move northward. Among these are black mangroves, whose abundance is steadily increasing in the northern Gulf of Mexico. A new article examines how this tropical species is impacting the salt marsh food web. Find out more...

Marine bacterium sheds light on control of toxic metals

Mon, 14 Jan 2019 16:11:31 EST ~ An ocean-dwelling bacterium has provided fresh insights into how cells protect themselves from the toxic effects of metal ions such as iron and copper. Although essential to life, metal ions can also generate reactive oxygen species (ROS) -- highly reactive molecules that damage cells as they try to form bonds with other molecules. In humans, reactive oxygen species are linked to aging and also to diseases such as cancers. Find out more...
