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

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

Marine mammals and sea turtles recovering after Endangered Species Act protection
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.

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

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

New conservation practice could reduce nitrogen pollution in agricultural drainage water
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.

Black mangroves' impact on the salt marsh food web
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.

Marine bacterium sheds light on control of toxic metals
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.

Fossil deposit is much richer than expected
Near the Dutch town of Winterswijk is an Eldorado for fossil lovers. A student has now analyzed pieces from museums and private collections for his master's thesis. He found an amazing amount of almost completely preserved skeletons, between 242 and 247 million years old. The good condition is presumably due to particularly favorable development conditions. These make Winterswijk a cornucopia for paleontology.

Far-ranging fin whales find year-round residence in Gulf of California
Researchers from Mexico and the United States have concluded that a population of fin whales in the rich Gulf of California ecosystem may live there year-round -- an unusual circumstance for a whale species known to migrate across ocean basins.

Fish farmers of the Caribbean
There are only so many fish in the sea. And our appetite for seafood has already stressed many wild fisheries to the breaking point. Meanwhile, the planet's growing population will only further increase the need for animal protein, one of the most resource-intensive types of food to produce.

Murky water keeps fish on edge
Fish become anxious and more cautious when water quality is degraded by sediment, an effect that could stunt their growth and damage their health.

15-meter-long ancient whale Basilosaurus isis was top marine predator
The stomach contents of ancient whale Basilosaurus isis suggest it was an apex predator, according to a new study.

Sunscreen and cosmetics compound may harm coral by altering fatty acids
Although sunscreen is critical for preventing sunburns and skin cancer, some of its ingredients are not so beneficial to ocean-dwelling creatures. In particular, sunscreen chemicals shed by swimmers are thought to contribute to coral reef decline. Now, researchers say that one such chemical, octocrylene (OC), which is also in some cosmetics and hair products, accumulates in coral as fatty acid esters that could be toxic to the marine organism.

Giant singers from neighboring oceans share song parts over time
Singing humpback whales from different ocean basins seem to be picking up musical ideas from afar, and incorporating these new phrases and themes into the latest song, according to a newly published study that's helping scientists better understand how whales learn and change their musical compositions.

Algae thrive under Greenland sea ice
Microscopic marine plants flourish beneath the ice that covers the Greenland Sea, according to a new study. These phytoplankton create the energy that fuels ocean ecosystems, and the study found that half of this energy is produced under the sea ice in late winter and early spring, and the other half at the edge of the ice in spring.

Variable venom: Why are some snakes deadlier than others?
By comparing records of venom potency and quantity for over 100 venomous snake species, researchers have discovered that the potency of a snake's venom depends on what it eats.

Female penguins are getting stranded along the South American coast
Every year, thousands of Magellanic penguins are stranded along the South American coast -- from northern Argentina to southern Brazil -- 1,000 kilometers away from their breeding ground in northern Patagonia. Now researchers have new evidence to explain the observation that the stranded birds are most often female: female penguins venture farther north than males do, where they are apparently more likely to run into trouble.
