2013 Ocean Health Index shows food provision remains an area of great concern
In the 2013 Ocean Health Index an annual assessment of ocean health lead by Ben Halpern, a research associate at UC Santa Barbara's National Center for Ecological Analysis and Synthesis and professor at the Bren School of Environmental Science & Management scientists point to food provision as the factor that continues to require serious attention.

Illinois river otters exposed to chemicals banned decades ago
Researchers report that river otters in Central Illinois are being exposed to polychlorinated biphenyls and pesticides that were banned in the US in the 1970s and '80s. Their analysis appears in the journal Ecotoxicology and Environmental Safety.

How tiny organisms make a big impact on clean water
Nearly every body of water contains microscopic organisms that live attached to rocks, plants, and animals. These sessile suspension feeders are critical to aquatic ecosystems and play an important role in cleaning up environmental contaminants by consuming bacteria. A study reveals that by changing the angle of their bodies relative to the surfaces, these feeders overcome the physical constraints presented by underwater surfaces, maximize their access to fresh, nutrient-rich water, and filter the surrounding water.

Sex over survival: Reproductive trait in fish impedes tissue regeneration
New research on the reproductive habits of zebrafish offers an explanation as to why some animals' bodies repair tissues. The research team previously noticed that male zebrafish regenerate their pectoral fins poorly, as compared to females. Their latest findings reveal the basis for this sex-specific regenerative deficiency: structures that are used to improve reproductive success. The scenario represents an example of the tradeoffs between reproduction and survival.

Predators vs. alien: European shrimps win predatory battles with an American invader
British and Canadian ecologists have discovered that native European shrimps resist the invasion of lakes and rivers by an American shrimp, by killing and eating the colonists. The study was published in the open access journal NeoBiota.

How red crabs on Christmas Island speak for the tropics
Research conducted through Princeton University found that erratic rainfall -- which could become more irregular as a result of climate change -- could be detrimental to animals that migrate with the dry-wet seasonal cycle. The researchers studied the annual mating migration of the land-dwelling Christmas Island red crab in order to help scientists understand the consequences of climate change for the millions of migratory animals in Earth's tropical zones.

Wetland restoration in the northern Everglades: Watershed potential and nutrient legacies
To most people, restoration of Florida's Everglades means recovering and protecting the wetlands of south Florida. What many don't realize is how intimately the fortunes of the southern Everglades are tied to central Florida's Lake Okeechobee and lands even further north. Restoration of this northern Everglades ecosystem will be discussed at the ASA, CSSA, and SSSA Annual Meetings on Nov. 3-6 in Tampa, FL.

Crowdsourcing seahorses: New smartphone app offers hope for seahorse science and conservation
Marine conservationists from the University of British Columbia, Zoological Society of London, and John G. Shedd Aquarium, Chicago today launched a smartphone app that could lead to new discoveries about some of the ocean's most mysterious and threatened animals -- seahorses -- and pave the way for similar efforts with other difficult-to-study species.

Water and lava, but -- curiously -- no explosion
A new study finds that hollow, land-based lava pillars in Iceland likely formed in a surprising reaction where lava met water without any explosion occurring. Formations like these are common in the ocean, where high pressure prevents explosion, but the scientists believe this is the first time such structures have been described on land.

More than 500 million people might face increasing water scarcity
Both freshwater availability for many millions of people and the stability of ecosystems such as the Siberian tundra or Indian grasslands are put at risk by climate change. Even if global warming is limited to two degrees above pre-industrial levels, 500 million people could be subject to increased water scarcity -- while this number would grow by a further 50 percent if greenhouse-gas emissions are not cut soon. At five degrees global warming almost all ice-free land might be affected by ecosystem change.

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.

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.
