Now, in a new paper in Science Advances, Cramer has combined fossil data, historical records, and underwater survey data to reconstruct the abundance of staghorn and elkhorn corals over the past 125,000 years. She finds that these corals first began declining in the 1950s and 1960s, earlier than previously thought.
If you live in a small community where fishing is your primary source of income and nutrition, it's tough to hear you might have to slow, stop or change your activities to more sustainably manage your fish stocks.
The Fish and Climate Change Database -- or FiCli (pronounced "fick-lee") -- is a searchable directory of peer-reviewed journal publications that describe projected or documented effects of climate change on inland fishes. Researchers, fisheries managers, conservationists, journalists and others can use FiCli to find scientific articles.
Postgraduate student Ekaterina Krol and Senior Research Associate at the Department of Applied Ecology of St Petersburg University Ivan Nekhaev have found a marine snail from the subclass Neomphaliones in a collection from the Soviet Arctic expeditions of the 1930s. For over 70 years, it has been mistakenly placed in another family of marine molluscs. It is noteworthy that representatives of the subclass Neomphaliones have been found in such specific habitats as sunken wood and hydrothermal vents.
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.
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.
