Key ocean fish can prevail with changes to farmed fish, livestock diets

Thu, 14 Jun 2018 21:38:22 EDT ~ A new study shows that if current aquaculture and agriculture practices remain unchanged into the future, wild forage fish populations likely will be overextended by the year 2050, and possibly sooner. However, making sensible changes in aquaculture and agriculture production would avoid reaching that threshold. Find out more...

Climate change has fish moving faster than regulations can keep up

Thu, 14 Jun 2018 21:37:27 EDT ~ The world's system for allocating fish stocks is being outpaced by the movement of fish species in response to climate change, according to a study undertaken by an international team of marine ecologists, fisheries and social scientists, and lawyers.

Stress test to predict how diatoms will react to ocean acidification

Wed, 13 Jun 2018 16:26:56 EDT ~ Researchers have shown that diatoms can withstand population collapse in an acidified environment by conserving valuable energy normally used for carbon dioxide consumption. Find out more...

Attacking bacteria with shark skin-inspired surfaces

Wed, 13 Jun 2018 11:37:48 EDT ~ Sharks are often the subject of TV specials or news stories focusing on their attacks on humans. But scientists are finding that sharks could inspire a new type of surface that would attack bacteria, helping humans instead of hurting them. Researchers have designed a coating that is infused with antimicrobial agents and has the patterned diamond-like texture of shark skin. Find out more...

Large-scale whaling in north Scandinavia may date back to 6th century

Wed, 13 Jun 2018 11:37:45 EDT ~ The intensive whaling that has pushed many species to the brink of extinction today may be several centuries older than previously assumed. Find out more...

Sea urchins see with their feet

Tue, 12 Jun 2018 10:57:24 EDT ~ Sea urchins lack eyes, but can see with their tentacle-like tube feet instead, previous research has indicated. Now, researchers have tested their vision in a new study, and shown that while sea urchins have fairly low resolution vision -- it is good enough to fulfill their basic needs. Find out more...

Putting animals in their best light: Some shades of LED lamps threaten wildlife

Tue, 12 Jun 2018 09:06:18 EDT ~ A research team identifies harmful effects to wildlife as LED lights proliferate. Some hues, including blues and whites, imperil creatures while other wavelengths are more benign. They devised an interactive web-based tool to help people make wildlife-friendly choices in outdoor lighting. Find out more...

Volcanic activity, declining ocean oxygen triggered mass extinction of ancient organisms

Mon, 11 Jun 2018 16:05:10 EDT ~ Global climate change, fueled by skyrocketing levels of atmospheric carbon dioxide, is siphoning oxygen from today's oceans at an alarming pace -- so fast that scientists aren't entirely sure how the planet will respond. Find out more...

Fueling a deep-sea ecosystem

Mon, 11 Jun 2018 15:27:42 EDT ~ Miles beneath the ocean's surface in the dark abyss, vast communities of subseafloor microbes at deep-sea hot springs are converting chemicals into energy that allows deep-sea life to survive -- and even thrive -- in a world without sunlight. Until now, however, measuring the productivity of subseafloor microbe communities -- or how fast they oxidize chemicals and the amount of carbon they produce -- has been nearly impossible.
