Geology
Oxygen-depleted toxic oceans had key role in mass extinction over 200 million years ago
Changes in the biochemical balance of the ocean were a crucial factor in the end-Triassic mass extinction, during which half of all plant, animal and marine life on Earth perished, according to new research involving the University of Southampton.

Agricultural contaminant impacts fish reproductive behavior
A common growth-promoting hormone used worldwide in the cattle industry has been found to affect the sexual behaviors of fish at a very low concentration in waterways -- with potentially serious ecological and evolutionary consequences.

Polar bears unlikely to thrive on land-based foods
Polar bears, increasingly forced on shore due to sea ice loss, may be eating terrestrial foods including berries, birds and eggs, but any nutritional gains are limited to a few individuals and likely cannot compensate for lost opportunities to consume their traditional, lipid-rich prey -- ice seals.

New study highlights the value of local knowledge in recovering endangered species
The study, co-authored by NOAA Fisheries, the University of Washington, and researchers from the University of Alaska, Fairbanks, explores how recreational anglers' understanding of the ecosystem and fishing practices influence their views of conserving bocaccio, canary rockfish, and yelloweye rockfish in Puget Sound.

Better method for forecasting hurricane season
A better method for predicting the number of hurricanes in an upcoming season has been developed by a team of University of Arizona atmospheric scientists. The UA team's new model improves the accuracy of seasonal hurricane forecasts for the North Atlantic and the Gulf of Mexico by 23 percent. The team's research paper was published online in the journal Weather and Forecasting on March 25.

Bacteria play an important role in the long term storage of carbon in the ocean
The ocean is a large reservoir of dissolved organic molecules, and many of these molecules are stable against microbial utilization for hundreds to thousands of years. They contain a similar amount of carbon as compared to carbon dioxide in the atmosphere. Researchers at the Helmholtz Centre for Environmental Research, the University of South Carolina and the Helmholtz Centre Munich found answers to questions about the origin of these persistent molecules in a study published in Nature Communications.

The 'intraterrestrials': New viruses discovered in ocean depths
The intraterrestrials, they might be called. Strange creatures live in the deep sea, but few are odder than the viruses that inhabit deep ocean methane seeps and prey on single-celled microorganisms called archaea.

Scientists discover elusive secret of how continents formed
An international research team, led by a Virginia Tech geoscientist, has revealed information about how continents were generated on Earth more than 2.5 billion years ago -- and how those processes have continued within the last 70 million years to profoundly affect the planet's life and climate.

Discovery of 2 new species of primitive fishes
Working with an international team, paleontologists at the University of Zurich have discovered two new species of Saurichthys. The ~242 million year old predatory fishes were found in the fossil Lagerstätte Monte San Giorgio, in Ticino. They are distinct from previously known Saurichthys species in the shape of the head and body, suggesting different habitats and diet.
