One possible solution, advanced by NSERC grantee Dr. Suzana Dragicevic of Simon Fraser University (SFU) in British Columbia involves digital maps and mathematical analysis to visualize and better understand the location of the most vulnerable marine habitats. These so-called ‘geospatial’ approaches have already been used widely in managing land-based resources to help build consensus among stakeholders with conflicting interests.
“Many environmental problems, including by-catch, are spatial in nature, explains Dragicevic, associate professor and director of the Spatial Analysis and Modeling Laboratory in SFU’s Geography Department. “To resolve them you need to build an accurate and objective view of the environment in question.”
Dragicevic will present her methods on February 15 during a seminar at the 2008 meeting of the American Association for the Advancement of Science (AAAS) in Boston.
What makes the challenge daunting is the conflict between commercial fisheries driven by profit maximization and an increasingly determined conservation community intent on protecting as much as 30 per cent of the world’s marine habitats. “We must certainly be mindful of the need to protect marine biodiversity, but we can’t forget those who are dependent on the fishery for their livelihoods,” says Dragicevic, who is also funded by the Social Sciences and Humanities Research Council of Canada.
To find common ground, Dragicevic employs a mathematical optimization process known as multi-criteria evaluation. This tool factors in the competing preferences of stakeholders to help authorities arrive at management decisions acceptable to all parties.
“Multi-criteria analysis has long been successful in resolving conflicts over terrestrial resource management such as land-use suitability analysis and urban development. Recently, we have shown how the approach can be applied to marine environments.”
Dragicevic, in collaboration with Louisa Wood, a doctoral researcher at the University of British Columbia’s Fisheries Centre, tested their approach under a pilot project in the Pacific Canadian Exclusive Economic Zone (EEZ). The results, published in the Biodiversity and Conservation Journal, confirmed that the methodology can help decision-makers wrestle with the complex trade-offs between fishing and biodiversity conservation.

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.
To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...
Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
