Methane seeps of the deep sea: A bacteria feast for lithodid crabs
Cold seeps are the basis for a surprising diversity in the desert-like deep sea. Off the coast of Costa Rica, an international team of scientists documented lithodid crabs of the genus Paralomis sp. grazing bacterial mats at a methane seep. The analysis results and a time-lapse video, published in the online journal PLOS ONE, show that not only sessile organisms benefit from the productivity around the cold seeps.

Exceptional fossil fish reveals new evolutionary mechanism for body elongation
The elongated body of some present-day fish evolved in different ways. Paleontologists from the University of Zurich have now discovered a new mode of body elongation based on a discovery in an exceptionally preserved fossilfish from Southern Ticino. In Saurichthys curionii, an early ray-finned fish, the vertebral arches of the axial skeleton doubled, resulting in the elongation of its body and giving it a needlefish-like appearance.

Plastic waste is a hazard for subalpine lakes too
Many subalpine lakes may look beautiful and even pristine, but new evidence suggests they may also be contaminated with potentially hazardous plastics. Researchers say those tiny microplastics are likely finding their way into the food web through a wide range of freshwater invertebrates too. The findings, based on studies of Italy's Lake Garda and reported on October 7th in Current Biology, suggest that the problem of plastic pollution isn't limited to the ocean.

Giant channels discovered beneath Antarctic ice shelf
Scientists have discovered huge ice channels beneath a floating ice shelf in Antarctica. At 250 meters high, the channels are almost as tall as the Eiffel tower and stretch hundreds of kilometers along the ice shelf. The channels are likely to influence the stability of the ice shelf and their discovery will help researchers understand how the ice will respond to changing environmental conditions.

Extrusive volcanism formed the Hawaiian Islands
A recent study by researchers at the University of Hawaii, Manoa and the University of Rhode Island changes the understanding of how the Hawaiian Islands formed. Scientists have determined that it is the eruptions of lava on the surface, extrusion, which grow Hawaiian volcanoes, rather than internal emplacement of magma, as was previously thought.

Warmer oceans could raise mercury levels in fish
Rising ocean surface temperatures caused by climate change could make fish accumulate more mercury, increasing the health risk to people who eat seafood, Dartmouth researchers and their colleagues report in a study in the journal PLOS ONE.

Genetic study of river herring populations identifies conservation priorities
A genetic and demographic analysis of river herring populations along the US east coast has identified distinct genetic stocks, providing crucial guidance for efforts to manage their declining populations. River herring include two related species, alewife and blueback herring, which migrate between freshwater spawning grounds and the ocean. The species are important for both ecological and economic reasons.

Accurate maps of streams could aid in more sustainable development of Potomac River watershed
Where a stream ends is clear, but where it begins can be more difficult to discern. Researchers from the University of Maryland Center for Environmental Science have developed a new method to solve this problem, resulting in a new map of the Potomac River watershed stream network that significantly improves the information needed for assessing the impact of urbanization on aquatic ecosystems.

Rare research into false killer whales reveals anti-predator partnerships
False killer whales (Pseudorca crassidens) are one of the least studied species of ocean dolphin, but new light has been cast on their behavior by a team of marine scientists from New Zealand. The research, published in Marine Mammal Science, reveals how a population off the coast of New Zealand has developed a relationship with bottlenose dolphins to defend themselves from predation.

Coral Reefs in the 21st Century
Exploring the future of our coral reefs
The current condition and future prospects of the world's coral reefs will be in the spotlight at a symposium of leading marine scientists in Townsville on 10-11 October 2013. Coral Reefs in the 21st Century will present the latest research, management and policy developments in coral reef systems in Australia, our region, and globally. It will feature talks by more than 30 eminent coral reef and fish scientists on these vital marine ecosystems.

October GSA Today: Earth upon Impact
In the October issue of GSA Today, Grant Young of the University of Western Ontario discusses the possible causes of the numerous glaciations that characterized the Neoproterozoic and concludes that a dramatic shift in Earth's climate may have occurred during the Ediacaran, in part due to a large marine impact. According to Young, this shift separates Proterozoic glaciations, which were likely triggered by the effect of supercontinent assembly and breakup on atmospheric carbon dioxide levels.

Longline fishery in Costa Rica kills thousands of sea turtles and sharks
The second-most-common catch on Costa Rica's longline fisheries in the last decade was not a commercial fish species. It was olive ridley sea turtles. These lines also caught more green turtles than most species of fish. These findings and more, reported in the Journal of Experimental Marine Biology and Ecology, indicate that the Costa Rican longline fishery represents a major threat to the survival of eastern Pacific populations of sea turtles as well as sharks.

Understanding soil nitrogen management using synchrotron technology
Increasing the organic matter in soils is key to growing crops for numerous reasons, including increased water-holding capacity and improved tilth. Scientists have recently used the Canadian Light Source to evaluate the effects of various sources of supplemental nitrogen fertilizer on the chemical composition of soil organic matter. Results of their experiments to study this question were recently published in the journal Biogeochemistry.

New technique helps biologists save the world's threatened seagrass meadows
Danish and Australian biologists have developed a technique to determine if seagrass contain sulfur. If the seagrass contains sulfur, it is an indication that the seabed is stressed and that the water environment is threatened. The technique will help biologists all over the world in their effort to save the world's seagrass meadows.

Cold, salty and promiscuous -- Gene-shuffling microbes dominate Antarctica's Deep Lake
Antarctica's Deep Lake is a saltwater ecosystem that remains liquid in extreme cold. For the first time, researchers describe a complete ecological picture of the microbial community thriving in Deep Lake. The detailed analysis appeared in the journal Proceedings of the National Academy of Sciences the week of September 30, 2013 and was led by scientists from the University of New South Wales, Australia partnered with the US Department of Energy Joint Genome Institute.

Breathing underwater: Evidence of microscopic life in oceanic crust
Scientists have recently documented that oxygen is disappearing from seawater circulating through deep oceanic crust, a significant first step in understanding the way life in the "deep biosphere" beneath the sea floor is able to survive and thrive. The new research findings were published in the journal Nature Communications on September 27, 2013, and are helping to redefine our concepts of the limits of life on our planet.
