A new University of Washington study that leverages historical data has found unique support for a "safety in numbers" strategy, where Pacific salmon living in larger groups have a lower risk of being eaten by predators. But for some salmon species, schooling comes at the cost of competition for food, and those fish may trade safety for a meal.
Gulf Star investment from Valero will support school environmental stewardship with youth in Port Arthur, Texas
Climate change might be behind an unusual disease outbreak among Antarctic fish. For about a decade, University of Oregon biologists John Postlethwait and Thomas Desvignes have been visiting the West Antarctic Peninsula. They study a unique group of fish that has adapted to the harsh polar environment. But on a 2018 field excursion, they noticed something especially strange: a large number of those fish were afflicted with grotesque skin tumors.
In The Journal of the Acoustical Society of America, scientists in Denmark review recent experiments and find noise regulations may need to be changed to protect porpoises, seals, and other sea-dwelling mammals. Current guidance for seals and porpoises is based on few measurements in a limited frequency range; the guidance is still valid for these frequencies, but investigators found substantial deviations in recent studies of the impact of low frequency noise on seals and high frequency noise on porpoises.
In bubbling vents off the coast of Ischia, a volcanic island in the Gulf of Naples, lives a curious population of black sea urchins. For at least 30 years, they have lived in these low pH, carbon dioxide-rich environments – a proxy for climate change-induced acidic oceans.
Even with plenty of fish in the sea, sea dragons stand out from the crowd. The funky, fabulous fish are bedecked with ruffly leaf-like adornments. Their spines are kinked. They’re missing their ribs and their teeth. And the responsibility of pregnancy is taken on by the males. By sequencing the genomes of two species of sea dragons, University of Oregon researchers have found genetic clues to the fish’s distinctive features: They’re missing a key group of genes found in other vertebrates. Those genes help direct the development of the face, teeth and appendages, as well as parts of the nervous system.
Woods Hole Oceanographic Institution (WHOI), the University of Connecticut, and Bigelow Laboratory for Ocean Sciences have executed a license agreement for a kelp germplasm, or collection of microscopic cells called gametophytes, containing more than 1,200 samples all developed and isolated by WHOI and UConn-led teams.

As rising sea levels cause marshes to move inland in six mid-Atlantic states, the coastal zone will not continue to serve as a carbon sink but release more carbon into the atmosphere, a new modeling study led by researchers at Duke University finds.
The effects of global climate change already are resulting in the loss of sea ice, accelerated sea level rise, and longer and more intense heat waves, among other threats. Now, the first-ever survey of planktonic lipids in the global ocean predicts a temperature-linked decrease in the production of essential omega-3 fatty acids, an important subset of lipid molecules.
Researchers from the University of Portsmouth say a ‘one size fits all’ approach to preserving mangrove forests will not work
An innovative tool will holistically examine and diagnose key processes with numerical simulations and experiments and predict changes in responses to water management, ecological restoration and climate change. It is designed to provide a suite of environmental and ecological information on the state of the greater Florida Bay ecosystem as well as potential future changes. Importantly, this model could potentially predict underwater aquatic vegetation coverage, harmful algal blooms, and fisheries resources under climate change and/or Comprehensive Everglades Restoration Program management scenarios.

Environmental chemical pollution threatens biodiversity. However, the complexity of this pollution remains insufficiently recognised by decision-makers - this is what international researchers led by Gabriel Sigmund from the University of Vienna and Ksenia Groh from the Swiss Federal Institute of Aquatic Science and Technology (Eawag) argue in the most recent issue of “Science”. Their letter appears shortly before the international negotiations on the “post-2020 Global Biodiversity Framework”. These will take place from 21st of June in Nairobi (Kenya).
A team of U.S. and Chinese scientists mapping oil pollution across the Earth’s oceans has found that more than 90% of chronic oil slicks come from human sources, a much higher proportion than previously estimated. Their research, published in Science, is a major update from previous investigations into marine oil pollution, which estimated that about half came from human sources and half from natural sources.
