Basking sharks seek out winter sun

Mon, 20 Feb 2017 08:41:53 EST ~ The winter habits of Britain's basking sharks have been revealed for the first time. Scientists have discovered some spend their winters off Portugal and North Africa, some head to the Bay of Biscay and others choose a staycation around the UK and Ireland. Find out more...

Tool for a cleaner Long Island Sound

Sun, 19 Feb 2017 16:51:09 EST ~ Ecologists have pinpointed sources of nitrogen pollution along Long Island Sound, and shows municipalities what they might do to alleviate it. Find out more...

Congo River fish evolution shaped by intense rapids

Fri, 17 Feb 2017 16:10:05 EST ~ New research provides compelling evidence that a group of strange-looking fish living near the mouth of the Congo River are evolving due to the intense hydraulics of the river's rapids and deep canyons. The study reveals that fishes in this part of the river live in 'neighborhoods' that are separated from one another by the waters' turbulent flow. Find out more...

Underwater seagrass beds dial back polluted seawater

Thu, 16 Feb 2017 14:39:24 EST ~ Seagrass meadows -- bountiful underwater gardens that nestle close to shore and are the most common coastal ecosystem on Earth -- can reduce bacterial exposure for corals, other sea creatures and humans, according to new research. Find out more...

Whales use nested Russian-doll structure to protect nerve tissue during lunge dives

Thu, 16 Feb 2017 13:04:07 EST ~ Fin whales use two neatly packed levels of nested folds to protect the nerves along the floor of their mouth during lunge feeding, according to new research. Find out more...

Scientists find evidence of Alaskan ecosystem health in Harlequin ducks

Thu, 16 Feb 2017 12:05:42 EST ~ Harlequin Ducks in coastal areas of Alaskas Kodiak and Unalaska islands are exposed to environmental sources of mercury and that mercury concentrations in their blood are associated with their local food source, mainly blue mussels, research shows. Find out more...

Biodiversity can promote ecosystem efficiency

Thu, 16 Feb 2017 11:00:06 EST ~ Humans influence evolution. In the case of whitefish in Swiss lakes, one consequence of this is replacement of a diversity of specialized species by fewer generalists. A recent analysis now suggests that communities of diverse specialists utilize trophic resources more efficiently. Find out more...

90 percent of fish used for fishmeal are prime fish

Thu, 16 Feb 2017 10:40:04 EST ~ From 1950 to 2010, 27 percent of commercial marine landings were diverted to uses other than direct human consumption, a new research project has found. Find out more...

Extreme fluctuations in forage fish populations

Thu, 16 Feb 2017 10:39:54 EST ~ California sardine stocks famously crashed in John Steinbeck's 'Cannery Row.' New research, building on the pioneering work of Soutar and Isaacs in the late 1960s and others, shows in greater detail that such forage fish stocks have undergone boom-bust cycles for centuries, with at least three species off the US West Coast repeatedly experiencing steep population increases followed by declines long before commercial fishing began.

Whale-ship collisions

Thu, 16 Feb 2017 10:39:38 EST ~ Scientists and government officials met at the United Nations today to consider possible solutions to a global problem: how to protect whale species in their most important marine habitats that overlap with shipping lanes vital to the economies of many of the world's nations.
