A new study shows that plant materials originating in Arctic sea ice are significantly incorporated into marine food webs that are used for subsistence in local communities of the greater Bering Strait region. The research has the potential to demonstrate the importance of sea ice ecosystems as a source of food in Arctic waters in Alaska and beyond.
Current marine protected areas in the Southern Ocean need to be at least doubled to adequately safeguard the biodiversity of the Antarctic, according to a new CU Boulder study.
Feeding at the ocean's surface appears to play an important role in New Zealand blue whales' foraging strategy, allowing them to optimize their energy use.
A large marine heatwave would double the rate of the climate change impacts on fisheries species in the northeast Pacific by 2050, says a recently released study by researchers from the University of British Columbia and University of Bern.
Researchers from the Max Planck Institute for Marine Microbiology in Bremen have discovered a microbe that feeds on ethane at deep-sea hot vents. They also succeeded in cultivating this microbe in the laboratory. What is particularly remarkable is that the mechanism by which it breaks down ethane is reversible. In the future, this could allow to use these microbes to produce ethane as an energy source. The study has now been published in the journal mBio.
Antimicrobial resistance is responsible for some 700 000 deaths each year worldwide. In relation to this phenomenon, a team of researchers from IRD and CIRAD have raised the alarm regarding the development of antimicrobial-resistant bacteria in aquaculture, which is affecting fish production and human health worldwide. Their study, published in Nature Communications on ... April 2020, established for the first time a link between global warming and an increased risk of antimicrobial resistance, and warned against inappropriate use of antibiotics.
An analysis revealed that water samples held a cocktail of pharmaceuticals and other compounds, including antibiotics, antifungals, anticonvulsants, anesthetics, antihypertensive drugs, pesticides, flame retardants and more. Not all of these chemicals were found at every location, and sometimes amounts detected were low. But the ubiquity of contamination is concerning, scientists say.
In a review paper published in the journal Nature Reviews Earth & Environment, WHOI scientists review what they-- and their science colleagues from around the world--have learned from studying the spill over the past decade.
UH Mānoa Marine Mammal Research Program captures rare video of humpback whales nursing off of Maui.
Researchers from the universities of Palermo (Italy), Tsukuba (Japan) and Plymouth (UK) showed that elevated dissolved CO2 conditions can lead to a 45% decrease of fish diversity.
