An biologist from the University of Bonn brought a new octopus species to light from depths of more than 4,000 meters in the North Pacific Ocean. Researchers in Bonn have now published the species description and named the animal "Emperor dumbo" (Grimpoteuthis imperator). Just as unusual as the organism is the researchers' approach: in order to describe the new species, they did not dissect the rare creature, but instead used non-destructive imaging techniques.
Scientists have identified a new phylum of microbes found around the world that appear to be playing an important (and surprising) role in the global carbon cycle by helping break down decaying plants without producing the greenhouse gas methane. The phylum is named Brockarchaeota after Thomas Brock, a pioneer in the study of microbes that live in extreme environments who died on April 4.
A joint research study by the Pacific Water Research Centre at Simon Fraser University and the Fraser Basin Council points to the use of certified, nature-based solutions for protecting salmon and aquatic habitats in the Lower Mainland.
An antibiotic used to treat bacterial infections in humans is showing promise in treating stony coral, found throughout the tropical western Atlantic, including several areas currently affected by stony coral tissue loss disease. Preserving M. cavernosa colonies is important due to its high abundance and role as a dominant reef builder in the northern section of Florida's Coral Reef. Results show that the Base 2B plus amoxicillin treatment had a 95 percent success rate at healing individual disease lesions.
A new species of deep-sea dwelling dumbo octopus called Grimpoteuthis imperator sp. nov. has been described using a combination of MRI, micro-CT and minimally invasive gene analysis rather than traditional dissection methods. The findings are presented in the open access journal BMC Biology.
When it comes to friendships and rivalries, male dolphins know who the good team players are. New findings, published in Nature Communications by University of Bristol researchers, reveal that male dolphins form a social concept of team membership based on cooperative investment in the team.
Climate change is driving some fish into cooler, deeper waters. Now they may be faced with another challenge: how to make sense of a world drained of color. Duke and Exeter researchers report that even small increases in depth could make it harder for fish to discern the hues they use to find food, friends and family. They are trying to predict which species will be most impacted, and whether they'll be able to adapt.
A new study suggests the white shark population for the eastern north Pacific, especially those listed in the Gulf of California, might be underestimated. Researchers found that the mortality rates for these white sharks might be underestimated as well, as an illicit fishery for the species was uncovered in the Gulf of California, suggesting that fishers were killing many more white sharks than has been previously understood.
A new study has demonstrated how video games can be used as a citizen science approach to train artificial intelligence tools, with data contributing towards coral reef conservation efforts. The NeMO-Net video game, designed by researchers at NASA's Ames Research Center in California's Silicon Valley and led by principal investigator Dr Ved Chirayath, provides an educational and intuitive tool for players to learn about and explore coral reef ecosystems, whilst also bringing marine conservation research to wider audiences.
Microplastics--small plastic pieces less than 5 millimeters in length--are ubiquitous in the environment, and they can have significant effects on wildlife. A new study published in Environmental Toxicology and Chemistry reveals that there are multiple impacts of different microplastics--with varying sizes, shapes, and chemical makeup--to the survival, growth, and development of larval fathead minnows, an important prey species in lakes and rivers in North America.
