Hydropower dam energy without sacrificing Mekong food supply: New research offers solution

Thu, 07 Dec 2017 14:17:09 EST ~ Nearly 100 hydropower dams are planned for construction along tributaries off the Mekong River's 2,700-mile stretch. In a new article, researchers present a mathematical formula to balance power generation needs with the needs of fisheries downstream. Find out more...

The unique pentraxin-carbonic anhydrase protein regulates the ability of fish to swim

Thu, 07 Dec 2017 14:16:08 EST ~ A study has shown that carbonic anhydrase VI (CA VI) is present in some species as a combination of two proteins. Find out more...

Variation within species is critical aspect of biodiversity

Tue, 05 Dec 2017 12:00:26 EST ~ Concerns about biodiversity tend to focus on the loss of species from ecosystems, but a new study suggests that the loss of variation within species can also have important ecological consequences. Find out more...

World's heaviest bony fish identified and correctly named

Tue, 05 Dec 2017 10:42:11 EST ~ Japanese fish experts have identified and clarified the biological name of the world's heaviest bony fish ever caught. The 2,300 kilogram whopper is a Mola alexandrini bump-head sunfish, and not, as originally thought, a member of the more commonly known Mola mola ocean sunfish species. Find out more...

Fish exposed to treated wastewater have altered behavior

Tue, 05 Dec 2017 09:21:34 EST ~ Researchers have found that fish living downstream from a wastewater treatment plant showed changes to their normal behavior --- ones that made them vulnerable to predator --- when exposed to elevated levels of antidepressant drugs in the water. Find out more...

Drone photos offer faster, cheaper data on key Antarctic species

Thu, 30 Nov 2017 09:00:57 EST ~ Scientists flying drones in Antarctica have demonstrated a cheaper, faster and simpler way to gauge the condition of leopard seals, which can weigh more than a half ton and reflect the health of the Antarctic ecosystem that they and a variety of commercial fisheries rely on.

There's a deeper fish in the sea

Tue, 28 Nov 2017 19:00:33 EST ~ The ocean's deepest fish doesn't look like it could survive in harsh conditions thousands of feet below the surface. Instead of giant teeth and a menacing frame, the fishes that roam in the deepest parts of the ocean are small, translucent, bereft of scales -- and highly adept at living where few other organisms can. A new fish species, the deepest in the ocean, was just discovered. Find out more...

Sharks evolved aircraft-like attributes to suit habitats

Mon, 27 Nov 2017 15:20:41 EST ~ Researchers report that shark species have evolved diverse physical attributes to help them thrive in different ocean ecosystems. Find out more...

Fear of sharks influences seaweed growth on Fijian coral reefs

Mon, 27 Nov 2017 13:58:06 EST ~ Fishes' fear of sharks helps shape shallow reef habitats in the Pacific, according to new research. The study is the first clear case of sharks altering a coral reef ecosystem through an indirect effect - creating an atmosphere of fear that shifts where herbivores feed and seaweeds grow.

Health threat from mercury in freshwater fish could be blowing away in the wind

Wed, 22 Nov 2017 11:00:34 EST ~ Mercury is one of the top 10 chemical concerns for public health according to the World Health Organization (WHO). In more than half of Swedish lakes the mercury levels are so high that eating the fish is a threat to the health of people and wildlife. To make matters worse, the problem seems to have no solution in sight. But new research gives hope: the mercury problem could very well be blowing away in the wind. Find out more...
