New study shows impact of human-made structures on Louisiana's coastal wetlands
As Louisiana's wetlands continue to disappear at an alarming rate, a new study has pinpointed the human-made structures that disrupt the natural water flow and threaten these important ecosystems. The findings have important implications for New Orleans and other coastal cities that rely on coastal wetlands to serve as buffer from destructive extreme weather events.

Pipelines affect health, fitness of salmon
Pipelines carrying crude oil to ports in British Columbia may spell bad news for salmon, according to a new study. Exposure to an oil sands product -- diluted bitumen -- impairs the swimming ability and changes the heart structures of young salmon.

World's first successful artificial insemination of southern rockhopper penguin
DNA tests have confirmed that one of the three southern rockhopper penguin chicks born at Osaka Aquarium Kaiyukan between June 4 and 6 was conceived through artificial insemination. It is the world's first successful case of a southern rockhopper penguin being conceived through artificial insemination.

Philippine fishing and its links to Japan’s 'sea women'
A researcher is studying the ancient Japanese culture of “ama” – women who traditionally free-dive in the sea in search of seaweed, lobsters, snail “turbo” shells and, in the distant past, pearls – and its potential connections to Philippine maritime cultures.

Hidden values of open ocean
A team of scientists has for the first time attached a dollar value to several of the leading 'ecosystem services' -- or natural benefits -- provided by the Eastern Tropical Pacific Ocean, an immense region stretching west from the west coasts of North and South America.

Pterosaur flies safely home after 95 million years
With the help of University of Alberta scientists, a newly described pterosaur has finally flown home. This spectacular fossil material was discovered in a private Lebanese limestone quarry more than a decade ago and has led to what UAlberta paleontologist Michael Caldwell calls “priceless scientific findings.”

Good bacteria vital to coral reef survival
Good bacteria could be the key to keeping coral healthy, able to withstand the impacts of global warming and to secure the long term survival of reefs worldwide, say researchers.

Sea star death triggers ecological domino effect
A new study by marine ecologists has discovered that a mass mortality of sea stars resulted in a domino effect on the B.C. West Coast's Howe Sound marine ecology. In the summer of 2013, millions of sea stars along the West Coast contracted a wasting disease and died in one of the largest wildlife mass mortality events ever recorded.

The call of the sea: Mammalian evolutionary transitions back to the sea
Though mammals adapted on land, a new study has shown that during three major independent evolutionary events, a number of mammals hearkened back to the sea.

Contagious cancers are spreading among several species of shellfish
Direct transmission of cancer among marine animals may be much more common than once thought, new research suggests. The cancer, known as disseminated neoplasia, is a leukemia-like disease that affects bivalves in many parts of the world.

Fish out of water are more common than thought
Fish have evolved the ability to live on land many times, challenging the perception that this extreme lifestyle shift was likely to have been a rare occurrence in ancient times. New research shows 33 different families of fish have at least one species that demonstrates some terrestrial activity and, in many cases, these behaviors are likely to have evolved independently in the different families.

Cosmopolitan snow algae accelerate the melting of Arctic glaciers
The role of red pigmented snow algae in melting Arctic glaciers has been strongly underestimated, suggests a study. The new work shows a 13 percent reduction of the albedo over the course of one melting season caused by red-pigmented snow algal blooms.

'Coral zombies' may spell doom for coral reefs around world
Scientists have known for a while that coral reefs around the world are dying, and in a worst-case scenario they were counting on large, healthy-looking corals to repopulate. But a new study shows that these seemingly healthy colonies are 'Coral Zombies' with no reproductive ability, which makes them useless in a recovery effort.

Coral reefs facing a hot time and increased bleaching, especially along US coasts
A new NOAA outlook shows that many coral reefs across around the world will likely be exposed to higher-than-normal sea temperatures for an unprecedented third year in a row, leading to increased bleaching - and with no signs of stopping. While the bleaching event is global, it will hit the US hard.

Manta rays are local commuters, not long-distance travelers, study finds
Oceanic manta rays -- often thought to take epic migrations -- might actually be homebodies, according to a new study. A research team studied satellite-tracked manta rays to shed light on the lives of these mysterious ocean giants.

Heat sickens corals in global bleaching event
Australian scientists report that many surviving corals affected by mass bleaching from high sea temperatures on the northern Great Barrier Reef are the sickest they have ever seen.
