Sea turtles are known for relying on magnetic signatures to find their way across thousands of miles to the very beaches where they hatched. Now, researchers reporting in the journal Current Biology on May 6 have some of the first solid evidence that sharks also rely on magnetic fields for their long-distance forays across the sea.
Researchers at the University of Kansas have described a new species of fanged frog discovered in the Philippines known as the Mindoro Fanged Frog.
Marine scientists are calling on the EU to adopt a comprehensive plan to protect dolphins and porpoises from fisheries bycatch in European waters. To help address the bycatch issue, which is the primary global threat to dolphins and porpoises, the researchers put forward a framework to reduce bycatch levels.
Bacteria that thrive on methane released from the ocean floor are an important barrier preventing the greenhouse gas from reaching the atmosphere. A new study finds that these microbial communities flourish in seabed depressions and are more effective during the summer.
A study by the UPV/EHU's CBET research group and the University of Bordeaux has shown that graphene oxide nanomaterials, alone and combined with polycyclic aromatic hydrocarbons, pose a potential source of toxicity to fish, but at concentrations that are above the currently expected environmental levels. Under the conditions used in the research, high toxicity has not been detected, although the alteration of certain biomarkers has been observed.
A study published in Cretaceous Research expands the paleontological richness of continental fossils of the Lower Cretaceous with the discovery of a new water plant (charophytes), the species Mesochara dobrogeica. The study also identifies a new variety of carophytes from the Clavator genus (in particular, Clavator ampullaceus var. latibracteatus) and reveals a set of paleobiographical data from the Cretaceous much richer than other continental records such as dinosaurs'.
Biodiversity is of crucial importance to the marine ecosystem. The prohibition of trawling activities in the Hong Kong marine environment for two and a half years has significantly improved biodiversity, an inter-university study led by City University of Hong Kong (CityU) has found. Research results showed that the trawl ban could restore and conserve biodiversity in tropical coastal waters.
New research indicates that the legendary Sargasso Sea, which includes part of the Bermuda Triangle and has long featured in fiction as a place where ships go derelict, may actually be an important nursery habitat for young sea turtles. In a study led by a UCF researcher and published today researchers presented evidence of baby green sea turtles arriving at the Sargasso Sea after entering the ocean off the east coast of Florida.
We here describe a new species of pelomedusoid turtle from a geological formation in Madagascar otherwise known for its exquisitely preserved fossil birds, dinosaurs, and crocodilians. The new turtle possesses an unusually flattened skull combined with a particularly gracile lower jaw and enlarged tongue bones, which not only must have given it a frog-like appearance, but also suggests that it was a specialized suction feeder that fed on small-bodied living prey using quick strikes.
Deep down in the seafloor anaerobic microbes consume large amounts of methane, a potent greenhouse gas. Even though this process is a crucial element of the global carbon cycle, it is still poorly understood. Scientists from Bremen and Israel now found the solution to a long-standing enigma in this process: why methane carbon isotopes behave so differently than expected. In a joint effort with their colleagues they present the answer in the journal Science Advances.
