By Angela Herring, Northeastern University Northeastern University ecologist David Kimbro claims to have watched a lot of TV growing up, particularly The Brady Bunch. “You could kind of get a flavor for how an episode was going to turn out based on how Jan or Peter were faring—you know, the middle kids,” said Kimbro, an assistant professor in the Department of Marine and Environmental Sciences. He and his colleagues—associate professor Jon Grabowski and assistant professor...

Reef Fish Arrived In Two Waves
2014-04-11 10:11:10

University of California, Davis The world's reefs are hotbeds of biological diversity, including over 4,500 species of fish. A new study shows that the ancestors of these fish colonized reefs in two distinct waves, before and after the mass extinction event about 66 million years ago that wiped out the dinosaurs. Reef fish represent one of the largest and most diverse assemblages of vertebrates, according to Samantha Price, a postdoctoral researcher in the Department of Evolution and...

Sunken Logs Create New Habitats For Seafloor Animals
2014-04-10 14:25:36

MBARI When it comes to food, most of the deep sea is a desert. Many seafloor animals feed on marine snow—the organic remnants of algae and animals that live in the sunlit surface waters, far above. However, marine snow only falls as a light dusting and doesn’t have much nutritional value. Thus, any other sources of food that reach the deep sea provide a temporary feast. Even bits of dead wood, waterlogged enough to sink, can support thriving communities of specialized animals. A new...

Oyster aquaculture in the Potomac River estuary could result in significant improvements to water quality, according to a new NOAA and U.S. Geological Survey study published in the journal Aquatic Geochemistry. All of the nitrogen currently polluting the Potomac River estuary could be removed if 40 percent of its river bed were used for shellfish cultivation, according to the joint study. The researchers determined that a combination of aquaculture and restored oyster reefs may provide...

Global Management Of Small Freshwater Biofoulers Carries a Big Price Tag
2014-04-03 11:22:38

Cary Institute of Ecosystem Studies Anyone that has spent time at a seaside pier has witnessed the destruction barnacles wreak on boat hulls. But biofouling animals are not limited to marine environments. A new paper published in the journal Frontiers in Ecology and the Environment estimates that the global management of freshwater mussels, clams, and other clinging animals costs $277 million US dollars annually. Biofoulers are organisms that accumulate underwater on hard surfaces, to...

Energy-Efficient Robot Inspired By Atlantic Razor Clam Dynamics
2014-03-25 13:36:55

Lee Rannals for redOrbit.com - Your Universe Online Scientists have built a robotic clam that is able to replicate how an Atlantic razor clam can burrow itself into the sea soil using very little energy. The Atlantic razor clam is able to dig itself through sea soil at about 0.4 inches per second and can dig up to one-fourth of a mile using the amount of energy equivalent to a AA battery. "The clam's trick is to move its shells in such a way as to liquefy the soil around its body,...
