Climate change is exacerbating problems like habitat loss and temperatures swings that have already pushed many animal species to the brink. But can scientists predict which animals will be able to adapt and survive? Using genome sequencing, researchers from McGill University show that some fish, like the threespine stickleback, can adapt very rapidly to extreme seasonal changes. Their findings could help scientists forecast the evolutionary future of these populations.
Scientists help protect sharks by developing aquarium breeding programs that pair up individuals in ways that increase genetic diversity. In a new study in Scientific Reports, scientists undertook the largest-ever effort to artificially inseminate sharks.Their work resulted in 97 new baby sharks, including ones whose parents live on opposite sides of the country and a few that don't have fathers at all.
A new whole genome sequence for the Yap hadal snailfish provides insights into how the unusual fish survives in some of the deepest parts of the ocean. Xinhua Chen of the Fujian Agriculture and Forestry University and Qiong Shi of the BGI Academy of Marine Sciences published their analysis of the new genome May 13th in the journal PLOS Genetics.
A new study, by researchers from Simon Fraser University and the Department of Fisheries and Oceans, reveals the trade-offs of fish biodiversity--its costs and benefits to mixed-stock fisheries--and points to a potential way to harness the benefits while avoiding costs to fishery performance.
Some water strider males (Microvelia longipes) have enormous back legs relative to the rest of their body, which they use to guard egg-laying sites and to fight off rival males. William Toubiana, Abderrahman Khila and colleagues from the Universite? de Lyon in France report that the development of this exaggerated male sexual characteristic depends on the production of a ubiquitous growth factor, BMP11, also found in humans and mice. The study publishes 11th May, 2021 in the open-access journal PLOS Biology.
Numbers of two Mediterranean turtle species have risen in the last three decades - but in Cyprus the recoveries are happening at different rates, new research shows.
Thousands of sharks have been illegally caught in a Marine Protected Area (MPA) in the Indian Ocean, new research shows.
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.
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.
Sea turtles in the Cayman Islands are recovering from the brink of local extinction, new research shows.
