Estimating the feeding habits of corals may offer new insights on resilient reefs

Thu, 18 Oct 2018 14:11:49 EDT ~ Researchers have found that corals living in more productive waters take advantage of the increased food availability. The findings reevaluate scientific understanding of how corals survive and could aid predictions on coral recovery in the face of climate change. Find out more...

Piranha-like specimen, 150 million years old, is earliest known flesh-eating fish

Thu, 18 Oct 2018 14:11:29 EDT ~ Researchers have described a remarkable new species of fish that lived in the sea about 150 million years ago in the time of the dinosaurs. The new species of bony fish had teeth like a piranha, which the researchers suggest they used as piranhas do: to bite off chunks of flesh from other fish. Find out more...

Life on the floor of the Arctic Ocean, with rigor and in detail

Wed, 17 Oct 2018 14:10:11 EDT ~ In an extensive and rigorous study of animal life on the Central Arctic Ocean floor, researchers have shown that water depth and food availability influence the species composition, density, and biomass of benthic communities. Find out more...

Bacterioplankton: Taking their vitamins

Wed, 17 Oct 2018 12:44:51 EDT ~ New research finds that more bacterioplankton utilize vitamin B1 or B1 precursors from their environment than synthesize their own. The researchers also found that B1 availability can directly limit bacterioplankton growth, which could have larger impacts on aquatic microbial food webs, as well as energy and nutrient exchange.

A curious branch of plankton evolution

Wed, 17 Oct 2018 11:09:50 EDT ~ Planktonic foraminifera -- tiny, shelled organisms that float in the sea -- left behind one of the most complete fossil records of evolutionary history in deep sea deposits. Consequently, evolutionists have a relatively sturdy grasp on when and how new lineages arose. However, a new study reveals that one lineage evolved much more rapidly than everyone predicted, and researchers are looking beyond Darwin's original theories of gradual evolution to understand why.

Satellite tech to create more effective, 'true' shark sanctuaries

Tue, 16 Oct 2018 13:19:38 EDT ~ When they first set out to follow grey reef sharks around the Republic of the Marshall Islands (RMI), researchers intended to survey their movement in the protected waters there. What they found was a disturbing development for the Pacific island nation. Find out more...

Arctic sea ice decline driving ocean phytoplankton farther north

Mon, 15 Oct 2018 14:15:14 EDT ~ A new study reveals phytoplankton spring blooms in the Arctic Ocean, which were previously nonexistent, are expanding northward at a rate of one degree of latitude per decade. Although blooms did not previously occur in this area, phytoplankton were present in the Arctic's central basin at low biomass. The study also found the primary productivity of the phytoplankton, or the rate at which phytoplankton convert sunlight into chemical energy, is increasing during the spring blooms. Find out more...

Extensive trade in fish between Egypt and Canaan 3,500 years ago

Mon, 15 Oct 2018 10:04:51 EDT ~ Some 3,500 years ago, a brisk trade in fish on the shores of the southeastern Mediterranean Sea had already begun. This conclusion follows from the analysis of 100 fish teeth that were found at various archeological sites in what is now Israel. Find out more...

Sea snail shells dissolve in increasingly acidified oceans

Mon, 15 Oct 2018 08:46:11 EDT ~ Shelled marine creatures living in increasingly acidified oceans face a fight for survival as the impacts of climate change spread, a new study suggests. Find out more...

Did mosasaurs hunt like killer whales?

Fri, 12 Oct 2018 15:26:10 EDT ~ Researchers have examined the youngest-ever specimen of tylosaur ever found. Like orcas, mosasaurs might have used their bony noses to strike prey. Find out more...
