Some coral populations already have genetic variants necessary to tolerate warm ocean waters, and humans can help to spread these genes, a team of scientists from The University of Texas at Austin, the Australian Institute of Marine Science and Oregon State University have found. The discovery has implications for many reefs now threatened by global warming and shows for the first time that mixing and matching corals from different latitudes may boost reef survival.
A research team from Oregon State University has discovered that reservoirs on the Klamath River contain harmful algal blooms that are capable of travelling over 180 miles along the lower parts of the river in just a matter of days. These blooms are unaffected while travelling via hydroelectric turbines and ultimately lead to unsafe water conditions downriver in northern California.
A strain of bacteria that "breathes" uranium may hold the key to cleaning up polluted groundwater at sites where uranium ore was processed to make nuclear weapons.
With warming summer temperatures across Alaska, white spruce tree growth in Interior Alaska has declined to record low levels, while the same species in Western Alaska is growing better than ever measured before.
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.
