Around 2005, southern right whale calves off the coast of Argentina began dieing off at an unprecented rate (from 6 per year in 2005 to around 65 per year from 2005 to 2014). Scientists have never determined the cause until a recent Marine Mammal Science paper named a likely culprit: toxic algae blooms. Read about the new findings on EurekAlert!.

Video: Electric eels may be some of the most sophisticated marine predators in the animal kingdom, according to a recent Current Biology paper by Vanderbilt University researchers. Check out video of them in action here and read about their specialized hunting techniques on EurekAlert!.

A potential downside to the beaver's comeback (video)
The Eurasian beaver was brought back from near extinction and now thrives across Europe. But this conservation success story may have had at least one unintended and potentially harmful consequence. Scientists report in ACS' journal Environmental Science & Technology that when beavers build new dams where no previous beaver colonies existed, downstream levels of toxic methylmercury rise, at least temporarily.

Queen's researchers link crayfish decline in Algonquin Park lakes to lack of calcium
Researchers from Queen's University have linked the localized near-extinction of a native crayfish species in four lakes in Algonquin Park to declining calcium levels.

Nordic seas cooled 500,000 years before global oceans
The cooling of the Nordic seas towards modern temperatures started in the early Pliocene, half a million years before the global oceans cooled. A new study of fossil marine plankton published in Nature Communications today demonstrates this.

Scientists call for ambitious program to unlock the power of Earth's microbial communities
A consortium of 48 scientists from 50 institutions in the United States has called for an ambitious research effort to understand and harness microbiomes -- the communities of microorganisms that inhabit ecosystems as varied as the human gut and the ocean, to improve human health, agriculture, bioenergy, and the environment. Their proposal, published in the Oct. 30 issue of the journal Science, calls for a major research project to develop new research tools and collaborations that will unlock the secrets of Earth's microbial communities.

Electric eel: Most remarkable predator in animal kingdom
Recent research on the electric eel by Vanderbilt University biologist Ken Catania has revealed that it is not the primitive creature it has been portrayed. Instead, it has a sophisticated control of the electrical fields it generates that makes it one of the most remarkable predators in the animal kingdom.

Electric eels curl up to deliver even more powerful shocks
Electric eels temporarily paralyze their prey by shocking them with electricity using a series of brief, high-voltage pulses, much as a Taser would do. Now, a researcher has discovered that the eels can double the power of their electrical discharge by curling up their bodies. In bringing their tail up and around, the eels sandwich prey between the two poles of their electric organ, which runs most of the length of their long, flexible bodies.

NASA looks at winds, cloud extent of Patricia's remnant hybrid system
NASA's RapidScat analyzed the winds in the Gulf of Mexico that were associated with the hybrid storm the included the remnants of former Eastern Pacific Ocean Hurricane Patricia. NOAA's GOES-East satellite showed the extent of the hybrid system's cloud cover over the southeastern US on Oct. 27.

Marine reserves will need stepping stones to help fishes disperse between them
A massive field effort on the Belizean Barrier Reef has revealed for the first time that the offspring of at least one coral reef fish, a neon goby, do not disperse far from their parents. The results indicate that if marine protected areas aim to conserve such fishes, and biodiversity more broadly, then they must be spaced closely enough to allow larvae to disperse successfully between them.
