Vital role of marine predators in supplying nutrients to coral reef ecology

It's long been known that sharks help nourish coral reefs, but exactly to what extent has never been scientifically mapped out -- until now.

'We're sleepwalking into a mass extinction' say scientists

Species that live in symbiosis with others, which often occur in the most delicately balanced and threatened marine ecosystems such as coral reefs, are the slowest to recover their diversity if damaged, according to a team of scientists.

Hunting squid slowed by rising carbon levels

Scientists have found that high carbon dioxide levels cause squid to bungle attacks on their prey. Investigators said that the oceans absorb more than one-quarter of all the excess carbon dioxide (CO2) released into the atmosphere by humans and this uptake of additional CO2 causes seawater to become more acidic.

Seaweeds shelter calcifying marine life from acidifying oceans

Seaweeds create a chemical microenvironment at their surface, providing refuge for calcifying organisms that are at risk from decreasing oceanic pH, shows new research.

Marine researchers say recent sea star wasting disease epidemic defies prediction

Beginning in 2013, a mysterious disease crippled sea star populations up and down the U.S. west coast. Over a matter of months, many sea star species died in record-breaking numbers, though the ochre sea star was among the hardest hit. Now, researchers have analyzed just how much the populations of this species have declined, but they have not yet determined what factors might be contributing to the epidemic.
