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: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
