Pesticides significantly reduce biodiversity in aquatic environments
The pesticides, many of which are currently used in Europe and Australia, are responsible for reducing the regional diversity of invertebrates in streams and rivers by up to 42 percent, researchers report in the Proceedings of the National Academy of Sciences.

New 'embryonic' subduction zone found
A new subduction zone forming off the coast of Portugal heralds the beginning of a cycle that will see the Atlantic Ocean close as continental Europe moves closer to America.

Submarine springs reveal how coral reefs respond to ocean acidification
Ocean acidification due to rising carbon dioxide levels will reduce the density of coral skeletons, making coral reefs more vulnerable to disruption and erosion, according to a new study of corals growing where submarine springs naturally lower the pH of seawater. The study is the first to show that corals are not able to fully acclimate to low pH conditions in nature.

Global cooling as significant as global warming
International study confirms the link between global cooling and a crash in the marine ecosystem similar to that witnessed as a result of global warming.

Does including parasites upset food web theory? Yes and no, says new paper
A new paper in PLOS Biology this week shows that taking the unusual step of including parasites in ecological datasets does alter the structure of resulting food webs, but that's mostly due to an increase in diversity and complexity rather than the particular characteristics of parasites. The work answers some longstanding questions about the unique role parasites play in ecological networks.

Intense: Navy, civilian planners get big assist in storm predictions
With the arrival of the Atlantic hurricane and Pacific typhoon season -- and the often dangerous storms that can accompany it -- new technology sponsored by the Office of Naval Research will help Navy and civilian officials alike plan for stormy weather. The Coupled Ocean/Atmosphere Mesoscale Prediction System-Tropical Cyclone is a groundbreaking weather prediction model that offers forecasters a detailed look at tropical storms and accurate predictions of a storm's intensity from one to five days out.

Study of oceans' past raises worries about their future
A McGill-led international research team has completed the first global study of changes that occurred in the nitrogen cycle, at the end of the last ice age. Their study confirm that oceans are good at balancing the nitrogen cycle on a global scale. But the data also shows that it is a slow process that may take many centuries, raising worries about the effects of current changes in the ocean.

Dangerous strains of E. coli may linger longer in water than benign counterparts, study finds
A toxin dangerous to humans may help E. coli fend off aquatic predators, enabling strains of E. coli that produce the toxin to survive longer in lake water than benign counterparts, a new study finds. The research may help explain why water quality tests don't always accurately capture health risks for swimmers.

DNA sequencing uncovers secrets of white cliffs of Dover
The University of Exeter recently contributed to a major international project to sequence the genome of Emiliania huxleyi, the microscopic plankton species whose chalky skeletons form the iconic white cliffs of Dover. The results of the project are published this week in the journal Nature.

'Tailing' spiny lobster larvae to protect them
In a new study of spiny lobsters scientists from the University of Miami and Old Dominion studied the larval dispersal of this species in the Caribbean. The goal of the study was to describe the sources, sinks, and routes connecting the Caribbean spiny lobster metapopulation. The results led the team to propose marine resource management strategies that incorporate larval connectivity and "larval lobster credits" to sustain and rebuild exploited marine populations.

Oysters could rebound more quickly with limited fishing and improved habitat
A new study shows that combining improved oyster restoration methods with limits on fishing in the upper Chesapeake could bring the oyster population back to the Bay in a much shorter period of time. The study led by Michael Wilberg of the University of Maryland Center for Environmental Science's Chesapeake Biological Laboratory assessed a range of management and restoration options to see which ones would have the most likelihood of success.

Warm ocean drives most Antarctic ice shelf loss, UC Irvine and others show
Ocean waters melting the undersides of Antarctic ice shelves, not icebergs calving into the sea, are responsible for most of the continent's ice loss, a study by UC Irvine and others has found.

Putting flesh on the bones of ancient fish
This week in the journal Science, Swedish and Australian researchers present the miraculously preserved musculature of 380 million year old fossil fishes, revealed by unique fossils from a locality in north-west Australia. The finds will help scientists to understand how neck muscles and abdominal muscles -- "abs" -- evolved.

New fluorescent protein from eel revolutionizes key clinical assay
Unagi, the sea-going Japanese freshwater eel, harbors a fluorescent protein that could serve as the basis for a revolutionary new clinical test for bilirubin, a critical indicator of human liver function, hemolysis, and jaundice, according to researchers from the RIKEN Brain Science Institute. The discovery also sheds light on the mysterious and endangered Unagi that could contribute to its conservation.

Rapid adaptation is purple sea urchins' weapon against ocean acidification
In the race against climate change and ocean acidification, some sea urchins may still have a few tricks up their spiny sleeves, suggesting that adaptation will likely play a large role for the sea creatures as the carbon content of the ocean increases.

Questions rise about seeding for ocean C02 sequestration
A study suggests that iron fertilization, the process of putting iron into the ocean to encourage the growth of C02 capturing alga blooms, could backfire.

Research shows male guppies reproduce even after death
Performing experiments in a river in Trinidad, evolutionary biologist David Reznick at the University of California, Riverside and colleagues have found that male guppies -- small freshwater fish -- continue to reproduce for at least ten months after they die, living on as stored sperm in females, who have much longer lifespans than males. While it is well known that guppies store sperm, Reznick and his team had never before thought of the extent of the storage.

Moving iron in Antarctica
Georgia Tech research published online in Nature Communications indicates that diatoms stuff more iron into their silica shells than they actually need. As a result, there's not enough iron to go around, and the added iron during fertilization experiments may stimulate less productivity than expected.

Spanish researchers sequence the genome of global deep ocean
A team of Spanish researchers, coordinated by the Spanish National Research Council, has started to sequence the genome of the global deep ocean. They are using more than 2,000 samples of microorganisms collected in the Atlantic, Indian and Pacific Oceans during the Malaspina Expedition. This collection of marine microbial genomic, the first in the world on a global scale, will provide new clues about a reservoir of biodiversity yet to explore.

Harbor porpoises can thank their worst enemy, the killer whale for their success
The harbor porpoise (Phocoena phocoena) is a whale species that is doing quite well in coastal and busy waters. They are found in large numbers throughout the Northern Hemisphere from Mauritania to Alaska, and now researchers from the University of Southern Denmark explain why these small toothed whales are doing so well: The harbor porpoise can thank their worst enemy, the killer whale, for their success.

Genetic maps of ocean algae show bacteria-like flexibility
A seven-year effort by 75 researchers from 12 countries to map the genome of the coccolithophore, Emiliania huxleyi, has revealed a set of core genes that mix and match with a set of variable genes that likely allows E. huxleyi, or Ehux, to adapt to different environments. Their results are described in the latest issue of Nature.
