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.

Native tribes' traditional knowledge can help US adapt to climate change
New England's Native tribes, whose sustainable ways of farming, forestry, hunting and land and water management were devastated by European colonists four centuries ago, can help modern America adapt to climate change.

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.
