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.

The WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.
Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....
The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.
During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....
