A new global atlas reveals that up to 1.9 million km2 of the world's coastal waters are affected by artificial light at night, with significant impacts on marine organisms. The study uses a novel metric to determine the depth of light penetration and highlights the need for further research into the effects of ALAN pollution.
Research reveals that warm-water habitats in Upper Klamath Lake provide essential energy for cold-water fish during spring and fall, while providing limited food sources in summer. The study highlights the importance of considering multiple habitats for mobile species like redband trout in climate change conservation.
Researchers at Ruhr-University Bochum study coral reefs' reaction to climate change, discovering polyp bailout as a potential survival mechanism. The study reveals different species react with varying intensity to environmental stressors, and that individual polyps can survive and grow in new locations.
A new analysis reveals that plankton-eating fish play a central role in driving local spikes of extreme biological productivity in tropical coral reefs. These 'sweet spots' concentrate abundant fish production, making them optimal for fishing. The study's findings hold significance for the future of tropical reef fisheries as coral ree...
A team of scientists led by Piers Chapman will develop a sustainable blue decision support system to help West Coast communities dependent on fisheries. The project aims to provide climate-informed information for fisheries management and decision-making, enabling stakeholders to make better long-term decisions.
A team of researchers is studying the Flower Garden Banks and other reefs in the Gulf of Mexico to understand how fish populations use natural banks and habitats. The four-year study aims to improve knowledge of essential habitats for key reef fish components.
Research found that warming water temperatures and browning increase methylmercury transfer to phytoplankton, reducing essential polyunsaturated fatty acids. This impacts the food chain, exposing higher organisms to toxic mercury and compromising nutrition, posing a threat to human health.
Arctic krill detect tiny changes in light intensity during polar winter days, allowing them to maintain their daily biological rhythms. This adaptation enables the krill to synchronize their daily migrations with external light cues, such as twilight.
A new study published in Coral Reefs confirms that soft corals Plexaura kükenthali and Plexaura homomalla are two separate species. The research found significant differences in morphology, genetics, reproduction, and symbiotic relationships between the two species.
The Verrucomicrobiota group of bacteria plays a crucial role in degrading polysaccharides released by algae during spring blooms in the North Sea. These specialized bacteria consume hard-to-degrade sugars, including those containing sulfate and fucose, using unique pathways and organelle-like structures to avoid toxic compounds.
Researchers found that rusty crayfish exhibit increased diet specialization and boldness in mid-abundance lakes, where individual behaviors become more diverse. This specialization can lead to impacts on spawning fish populations and ecosystem dynamics.
Researchers successfully detected local mammals and birds by collecting 18 litres of water from a two-kilometre stretch along the river Mulde. The team identified 50% of fish species, 22% of mammal species, and 7.4% of breeding bird species in the region.
A new study found that Baltimore County's leaky sewage infrastructure delivers tens of thousands of human doses of pharmaceuticals to the Chesapeake Bay annually, affecting aquatic life and behavior. The study estimates that nearly 1% of raw sewage flows into the environment via leaking pipes.
A study by UC Santa Barbara's Marine Science Institute found that understory algae can't compensate for the lost productivity of giant kelp in kelp forests. The researchers discovered a gradual reduction in canopy productivity and an exponential increase in understory algae productivity over 10 years.
A new study from Oregon State University found that climate conditions significantly affect the reproductive success of mature female Antarctic krill. The researchers discovered a relationship between the condition of these females during spawning season and the proportion of juvenile krill in the population the following year.
Scientists at the University of Leicester discovered a correlation between tooth roughness and diet in animals. Tooth surfaces can reveal what an animal has been eating, providing a reliable method for studying wild diets.
