Many once-endangered marine species have reached recovery levels that may warrant them coming off of the endangered species list. This recovery is presenting new challenges however as human communities sometimes struggle to adapt to their sudden return. Read more on EurekAlert!.

Gigantic whales have stretchy 'bungee cord' nerves
University of British Columbia researchers have discovered a unique nerve structure in the mouth and tongue of rorqual whales that can double in length and then recoil like a bungee cord. The stretchy nerves explain how the massive whales are able to balloon an immense pocket between their body wall and overlying blubber to capture prey during feeding dives.

These gigantic whales have nerves like bungee cords
Nerves aren't known for being stretchy. In fact, 'nerve stretch injury' is a common form of trauma in humans. But researchers reporting in the Cell Press journal Current Biology on May 4 have discovered that nerves in the mouths and tongues of rorqual whales can more than double their length with no trouble at all.

Ocean fronts improve climate and fishery production, study finds
A recent study by the University of Georgia found that ocean fronts -- separate regions of warm and cool water as well as salt and fresh water -- act to increase production in the ocean. Brock Woodson's research, published in the Proceedings of the National Academy of Sciences, showed how fronts can be incorporated into current climate and fisheries models to account for small-scale interactions in fishery production and cycling of elements such as carbon and nitrogen in the ocean.

Lousy sockeye are lousy competitors
With major funding from several groups, including NSERC, an SFU doctoral student has made a key discovery regarding Fraser River sockeye's vulnerability to sea lice. Their recently published research indicates that juvenile Fraser River sockeye salmon that are highly infected with sea lice are 20 percent less successful at consuming food than their lightly infected counterparts. The study appears online in the Canadian Journal of Fisheries and Aquatic Sciences.

Listening for whales and fish in the Northwest Atlantic ocean
Scientists are using a variety of buoys and autonomous underwater vehicles to record and archive sounds from marine mammals and fish species in the western North Atlantic through a new listening network known as the US Northeast Passive Acoustic Sensing Network (NEPAN). Researchers hope NEPAN will be the first link in an extensive listening network that would extend along the entire US East Coast, and eventually to waters around the US.

NASA contributes to first global review of Arctic marine mammals
A recently published multinational study attempted to gauge the population trends of Arctic marine mammals and changes in their habitat, identify missing scientific information, and provide recommendations for the conservation of Arctic marine mammals over the next decades.

NASA sees Tropical Cyclone Quang develop an eye
Tropical Cyclone Quang strengthened during the early morning hours of April 30, Eastern Daylight Time/US, and developed an eye. The stronger Quang neared the coast of Western Australia and triggered warnings.

Fossils inform marine conservation
Fossils help predict which animals are likely to go extinct. Scientists combine information from the fossil record with information about hotspots of human impact to pinpoint animal groups and geographic areas of highest concern for marine conservation.

Tropical marine ecosystems most at threat from human impact
An international team of scientists has used the fossil record during the past 23 million years to predict which marine animals and ecosystems are at greatest risk of extinction from human impact. In a paper published in the journal Science, the researchers found those animals and ecosystems most threatened are predominantly in the tropics.
