In oxygen-poor parts of the ocean, some microorganisms survive by breathing arsenic. This holdover from the ancient Earth was not thought to still exist in the open ocean.
Lifelong chemical records stored in the canine teeth of an elusive group of harbor seals show that the seals remain in freshwater their entire lives and are likely a distinct population from their relatives in the ocean. Their home territory, Iliamna Lake, is in the heart of the proposed Pebble Mine project.
In the wild and in the lab, researchers find a relationship between higher water temperatures and a lower percentage of female flounder, a cause for concern.
An associate director of Mississippi State’s Northern Gulf Institute is receiving international attention for his eye-opening study on the impact exotic species have on native marine communities.
Researchers found out that the Arctic does not lose ice uniformly. Different seasonal patterns are at play depending on region: From the early 2000s, the ice cover in the Eurasian Arctic has been shrinking even in the winter period, while the American region only lost ice in the summer. The team explains this in terms of seasonal memory: a response of the winter ice cover to the atmospheric conditions in the previous summer.
New research provides the most complete account to date of the viruses that impact the world’s oceans, increasing the number of known virus populations tenfold. This new study brings the total known marine viral populations within the ocean close to 200,000 – work that will help scientists better understand their influence throughout the world, including their part in delivering carbon deep into the sea, protecting the atmosphere from further damage. The study, led by researchers at Ohio State, appears online April 25 in the journal Cell.
In recent years, seaweeds have been notorious for washing up and fouling beaches on Long Island. Now, a collaborative team of scientists and marine farmers have demonstrated that the seaweed, sugar kelp, can be cultivated in the shallow estuaries of Long Island, a breakthrough that may unlock a wealth of economic and environmental opportunities for coastal communities.
Global warming has caused twice as many ocean-dwelling species as land-dwelling species to disappear from their habitats, a unique Rutgers-led study found. The greater vulnerability of sea creatures may significantly impact human communities that rely on fish and shellfish for food and economic activity, according to the study published in the journal Nature.
St. Mary’s College of Maryland students Lauren Swam '19, Isaac Hersh '19, and Colin Cassady '19, recently had a firsthand experience studying marine ecology on the coral reefs of Belize. Interviewed for The Naturalist Podcast (http://www.naturalistpodcast.com/the-naturalist-podcast-episode-27-on-carrie-bow-cay-with-lauren-isaac-and-colin/), the three shared their encounters towing through seagrass beds, snorkeling mangrove forests, and doing research on coral reefs with Seabird McKeon, visiting professor in the biology department.
Photos taken months, and in some cases years, apart by scuba divers show female sand tiger sharks returning to the same shipwrecks off the North Carolina coas
Researchers, including a team from The Ohio State University, have published new findings showing that the DNA of the tube anemone does what few other species’ mitochondrial genomes have been shown to do. It defies the classic doughnut shape it “should” be in and is arranged in several fragmented pieces, the number of which vary depending on the species. On top of that, the animal now holds the record for the largest mitochondrial genome reported to date. It contains almost 81,000 base pairs, or pieces of genetic information, according to the new study, published online in the journal Scientific Reports. Human mitochondrial DNA contains fewer than 17,000 base pairs.
