Loss of large carnivores poses global conservation problem
In ecosystems around the world, the decline of large predators such as lions, dingoes, wolves, otters, and bears is changing the face of landscapes from the tropics to the Arctic -- but an analysis of 31 carnivore species published today in the journal Science shows for the first time how threats such as habitat loss, persecution by humans and loss of prey combine to create global hotspots of carnivore decline.

Radiocarbon dating suggests white sharks can live 70 years and longer
Adult white sharks may live far longer than previously thought, according to a new study that used radiocarbon dating to determine age estimates for white sharks, also known as great whites, in the Northwest Atlantic Ocean. This first successful radiocarbon age estimate study analyzed vertebrae samples from eight white sharks; the oldest male was 73, the oldest female 40, suggesting previous studies have significantly underestimated longevity in sharks.

GPS traffic maps for leatherback turtles show hotspots to prevent accidental fishing deaths
Pacific leatherback turtles, among the most endangered animal populations in the world, often die hooked or tangled in industrial longlines that set thousands of hooks in the ocean to catch fish. In a new study in the Proceedings of the Royal Society B, researchers show the use-intensity distributions for 135 satellite-tracked adult turtles and distributions of longline fishing effort in the Pacific Ocean. The overlap of these distributions in space and time allows prediction of bycatch risk.

Coral chemical warfare: Suppressing a competitor enhances susceptibility to a predator
Competition may have a high cost for at least one species of tropical seaweed. Researchers examining the chemical warfare taking place on Fijian coral reefs have found that one species of seaweed increases its production of noxious anti-coral compounds when placed into contact with reef-building corals, but at the same time becomes more attractive to herbivorous fish.

Marine bacteria to fight tough infections
Aggressive infections are a growing health problem all over the world. The development of resistant bacteria is rampant and, in the United States, resistant staphylococci cause more deaths than AIDS on an annual basis. Researchers from the University of Copenhagen are studying a new form of treatment based on marine bacteria. The results have been published in PLOS ONE.

Researchers unveil rich world of fish biofluorescence
A team led by scientists from the American Museum of Natural History has released the first report of widespread biofluorescence in fishes, identifying more than 180 species that glow in a wide range of colors and patterns. Published today in PLOS ONE, the research shows that biofluorescence -- a phenomenon by which organisms absorb light, transform it, and eject it as a different color -- is common and variable among marine fish species, indicating its potential use in communication and mating.

Geological Society of America's top journal, Geology, begins 2014 with 10 new articles
New Geology postings extend the understanding of seawater chemistry by ~300 million years; determine erosion rates for exposure of today's southern Rocky Mountains; reveal new evidence for meltwater pulses; call mudstones "so complicated as to almost defy understanding"; describe a White Nile megalake; examine the oldest rocks on Earth; postulate that biomarkers heat up during earthquakes; investigate chemical denudation; describe plate tectonic influences on animal evolution; and analyze sulfides in abyssal peridotites.

Scientists to examine Pacific's 'global chimney'
NCAR scientists and partners next week launch a field project in the tropical Pacific, a remote region that holds a key to understanding worldwide climate. The warm waters fuel huge clusters of thunderstorms that act as a global chimney, lofting gases and particles into the stratosphere and affecting the planet.

Ancient sharks reared young in prehistoric river-delta nursery
Like salmon in reverse, long-snouted Bandringa sharks migrated downstream from freshwater swamps to a tropical coastline to spawn 310 million years ago, leaving behind fossil evidence of one of the earliest known shark nurseries.

Jumping snails left grounded in future oceans
Sea snails that leap to escape their predators may lose their extraordinary jumping ability because of rising carbon dioxide emissions, scientists have discovered. Lead author, Dr. Sue-Ann Watson from the ARC Centre of Excellence for Coral Reef Studies observed that the conch snail, which uses a strong foot to leap away from approaching predators, either stops jumping, or takes longer to jump, when exposed to carbon dioxide levels projected for the end of this century.

New organization brings together top researchers to sequence the genomes of invertebrates
To learn more about invertebrates, a cooperative consortium called the Global Invertebrate Genomics Alliance has been formed. The group will provide a network of diverse scientists to promote comparative genomics and bioinformatics research, on non-insect/non-nematode invertebrates.

MBL scientists to study coastal waterbird habitats through funding for Obama's Climate Action Plan
Secretary of the Interior Sally Jewell announced in December that Interior's eight regional Climate Science Centers (including the Northeast CSC, a consortium that includes the Marine Biological Laboratory in Woods Hole, Mass.) are awarding nearly $7 million to universities and other partners for research as part of President Obama's Climate Action Plan to reduce carbon pollution, move our economy toward clean energy sources, and prepare our communities for the impacts of climate change.

7 new species of nearctic wasps described and illustrated

Local factors cause dramatic spikes in coastal ocean acidity
Seawater samples collected from the marine estuary Beaufort Inlet, N.C., weekly for a year and on a daily and hourly basis for shorter periods were used to track changes in pH and dissolved inorganic carbon. Short-term variability in acidity over one year exceeds 100-year global predictions for the ocean as a whole and may already be exerting added pressure on some of the estuary's organisms, particularly shelled organisms.

Methane hydrates and global warming
Off the coast of Svalbard methane gas flares originating from gas hydrate deposits at depth of several hundred meters have been observed regularly. A new study conducted under the leadership of scientists from GEOMAR Helmholtz Centre for Ocean Research Kiel and MARUM in Bremen shows, that the observed outgassing is most likely caused by natural processes and can not be attributed to global warming. The study is published in the internationally renowned scientific journal Science.

Global average temperatures will rise at least 4°C by 2100 and potentially more than 8°C by 2200 if carbon dioxide emissions are not reduced according to new research published in Nature that shows our climate is more sensitive to carbon dioxide than most previous estimates.

DNA barcoding to monitor marine mammal genetic diversity
Marine mammals are flagship and charismatic species. Attractive for the general public, nowadays, they are also considered as highly relevant sentinel of the marine realm as indicator for environmental change. A recent paper in the open access journal Zookeys suggests that the use of DNA barcoding in conjunction with a stranding network will clearly increase the accuracy of the monitoring of marine mammal biodiversity.
