Ancient genetic markers in sockeye salmon can help manage healthier fish stocks

Thu, 25 May 2017 12:56:46 EDT ~ A recent study identifies new genetic markers in sockeye salmon that can help improve management of fish populations. Find out more...

New species of bus-sized fossil marine reptile unearthed in Russia

Thu, 25 May 2017 12:56:17 EDT ~ A new species of a fossil pliosaur (large predatory marine reptile from the 'age of dinosaur') has been found in Russia and profoundly change how we understand the evolution of the group, says an international team of scientists. Find out more...

Whales only recently evolved into giants when changing ice, oceans concentrated prey

Wed, 24 May 2017 11:00:24 EDT ~ A team of scientists have traced the evolution of whale size through more than 30 million years of history and found that very large whales appeared along several branches of the family tree about 2 to 3 million years ago. Increasing ice sheets in the Northern Hemisphere during this period likely altered the way whales' food was distributed in the oceans and enhanced the benefits of a large body size, the scientists say.

Going with the flow: The forces that affect species' movements in a changing climate

Wed, 24 May 2017 08:45:03 EDT ~ Ocean currents affect how climate change impacts movements of species to cooler regions. A new study provides novel insight into how species' distributions change from the interaction between climate change and ocean currents. Find out more...

Transforming how complex marine data is synthesized

Tue, 23 May 2017 14:41:13 EDT ~ Scientists are transforming how complex marine data from the Ocean Health Index is synthesized, communicated and used for coastal management. Find out more...

First deep-sea mussel genome decoded

Tue, 23 May 2017 12:41:48 EDT ~ Scientists have assembled the 1.64 gigabytes genome of a deep-sea mussel, which is roughly equivalent to 50 percent of the size of human genome. This is the first decoded genome among all deep-sea macrobenthic animals, revealing a complete set of DNA. Find out more...

Why more juvenile sharks off California's coast is a good thing

Fri, 19 May 2017 17:23:03 EDT ~ Young great white sharks are using Californias coasts as a sort of nursery, suggests new research. Find out more...

Iron deficiency restrains marine microbes

Fri, 19 May 2017 08:36:28 EDT ~ Iron is a critical nutrient in the ocean. Its importance for algae and the nitrogen cycle has already been investigated in detail. Now a new discovery shows that microbes also need iron to process phosphorus. A team of researchers has completed a study showing that iron can limit phosphorus acquisition in the ocean. Their study contributes to knowledge of nutrient cycling in the ocean. Find out more...

New coral reef fish species shows rare parental care behavior

Thu, 18 May 2017 14:38:55 EDT ~ The vast majority of coral reef fish produce large numbers of young that disperse into the ocean as larvae, drifting with the currents before settling down on a reef. A few reef fish, however keep their broods on the reef, protecting the young until they are big enough to fend for themselves. On a recent trip to the Philippines, researchers discovered a new species of damselfish that exhibits this unusual parental care behavior. Find out more...

Shedding light on Earth's first animals

Wed, 17 May 2017 15:47:31 EDT ~ More than 550 million years ago, the oceans were teeming with flat, soft-bodied creatures that fed on microbes and algae and could grow as big as bathmats. Today, researchers are studying their fossils to unlock the secrets of early life. Researchers now show that Dickinsonia developed in a complex, highly regulated way using a similar genetic toolkit to today's animals. Find out more...
