Despite of this potential conflict, Kai Chan, an NSERC-funded researcher at the University of British Columbia, believes there is a way to ensure Canadian First Nations fishers can benefit from the otters’ presence.
“Efforts to restore wildlife populations should not be played out in a win-lose framework that pits conservation against the economic interests of the local people,” observes Chan, who will be speaking at the American Association for the Advancement of Science (AAAS) Annual Conference in Boston, which runs from February 14 to 18.
While none of these shellfish were major sources of human food before the sea otters disappeared, they have become important to First Nations fishers over the last few hundred years. Given their fears about losing a big part of their livelihood, some of these fishers have even announced plans to hunt the rebounding otter populations.
Chan, however, believes that the impact of the otters will be multifaceted, for example with economic opportunities for local people in ecotourism.
The interaction between environmental and economic factors is made more complex by additional indirect ecological effects. For example, sea otters promote kelp forest recovery (by eating the urchins that destroy kelp) and thus foster a much richer ecosystem. This should greatly boost alternative fisheries for species such as lingcod, rockfish and herring.

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
