Can Dungeness crab and eelgrass help improve management of our marine resources?

18.02.2008
Putting theory into practice to manage complex and closely linked social and ecological systems along our coasts is a challenge, but one NOAA researcher Anne Guerry says can be addressed by a new approach to managing the value of our ocean resources.

Guerry will discuss the use of ecosystem services, the benefits that people obtain from ecosystems, in managing marine resources in her AAAS presentation “Ecosystem Services Provided by the Nearshore in Puget Sound: An Analysis of Change.” Puget Sound is home to 200 species of fish, 26 species of marine mammals, and over 625 species of seaweed, as well as 3.5 million people. How well the marine systems in Puget Sound function is directly linked to the region’s quality of life and economy.

Guerry and colleagues focused on Dungeness crab harvests and the distribution of eelgrass, which sequesters or stores carbon from greenhouse emissions, as models to illustrate how changes in nearshore habitats and various management scenarios can affect these ecosystem services. By examining various scenarios that are based on real choices facing decision-makers, the team can compare the effects of various management decisions on the delivery of these services.

For example, Guerry’s team gathered basic life history information about Dungeness crab and data on its abundance and harvests in the region. Using a model of the crab populations in the sound, they examined its sensitivity to changes in nearshore habitats and the resulting changes in harvestable crab. Those changes can ultimately be translated to changes in the dollar value of the crab harvest, and tracked through economic models to changes in other sectors of the economy.

The researchers also examined the ecosystem service of carbon storage provided by eelgrass habitats in the nearshore region of Puget Sound and the potential for it to change under different management scenarios. They mapped current known distributions of eelgrass, looked at known historical distributions and places where eelgrass has the potential to grow. Next they mapped various human impacts on eelgrass habitats, from shoreline armoring with bulkheads to overwater structures that block light and mechanical damage by dredging.

“Making ecosystem services a useful concept to Puget Sound ecosystem management requires basic research on how services vary across the region and how they might be affected by alternative management schemes,” Guerry said. “The principles we use in Puget Sound can be applied to other regions.”

Im Focus: Future electronic components to be printed like newspapers

A new manufacturing technique uses a process similar to newspaper printing to form smoother and more flexible metals for making ultrafast electronic devices.

The low-cost process, developed by Purdue University researchers, combines tools already used in industry for manufacturing metals on a large scale, but uses...

Im Focus: First evidence on the source of extragalactic particles

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.

To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...

Im Focus: Magnetic vortices: Two independent magnetic skyrmion phases discovered in a single material

For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.

Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...

Im Focus: Breaking the bond: To take part or not?

Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.

A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...

Im Focus: New 2D Spectroscopy Methods

Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.

"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
