An amendment has been approved by the Mid-Atlantic Fishery Management Council this week for the creation of “deep sea coral zones” in the Mid-Atlantic as a measure to protect deep sea corals that are vulnerable to damage from bottom-tending fishing gear. On approval from the Secretary of Commerce, the zones will be formed in the regions where corals have been widely found or likely to be present.
Petrel fledglings leave the nest after dark, but these marine birds' maiden flights towards the sea are hampered by city lights. Many collide or fall to the ground where they are in danger of being run over and vulnerable to predators. Now, a study has evaluated the impact of light pollution on three species of petrels on the Balearic Islands, including the Balearic shearwater, the most threatened sea bird in Europe, and concludes that between 30 and 47% of colonies are exposed to high levels of light pollution.
As the ocean absorbs atmospheric carbon dioxide (CO2) released by the burning of fossil fuels, its chemistry is changing. The CO2 reacts with water molecules, lowering the ocean's pH in a process known as ocean acidification. This process also removes carbonate ions, an essential ingredient needed by corals and other organisms to build their skeletons and shells.
Modern mountain climbers typically carry tanks of oxygen to help them reach the summit. It's the combination of physical exertion and lack of oxygen at high altitudes that creates one of the biggest challenges for mountaineers.
Many species are migrating toward Earth's poles in response to climate change, and their habitats are shrinking in the process, researchers say. Two new reports focusing on marine organisms, which have been moving pole-ward at higher rates than terrestrial creatures, show how factors, including those not directly related to climate change, are limiting the ranges of corals and fish.
The most aggressive largemouth bass in the lake are also the ones most prized by anglers. These are the fish that literally 'take the bait' and put the fun into both competitive and casual sport fishing.
Collaboration between ecologists and climate researchers in Norway has generated fascinating new insight into how seabirds are affected by climate change.
Ecologists from the University of York, together with the Wildlife Conservation Society (WCS) and the Uganda Wildlife Authority (UWA), have developed a new method to better identify where poachers operate in protected areas.
Researchers have developed a model to assess how dams affect the viability of sea-run fish species that need to pass dams as they use both fresh and marine waters during their lifetimes. NOAA's Northeast Fisheries Science Center (NEFSC) and Greater Atlantic Regional Fisheries Office (GARFO) have partnered on this project to test how varying passage efficiency at dams related to survival rates for these species.
Invasive earthworms in New England's forests are absorbing toxic metal pollutants in potentially hazardous levels that may be contributing to a decline in birds, amphibians and mammals that feed on them, a Dartmouth-led study finds.
