Resilience concepts poised to aid management of coastal marine ecosystems
01-02-2008 · EurekAlert!Insights into the processes that drive changes in coastal areas have yielded new directions for research, monitoring and management of such regions, which are prone to sudden ecological shifts. Innovative management approaches inspired by modeling of coastal ecosystems are already being put into place.

- Can Dungeness crab and eelgrass help improve management of our marine resources?
02-16-2008 · EurekAlert!
NOAA's Anne Guerry will discuss the benefits 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.

- 'Ten Commandments' could improve fisheries management
02-18-2007 · EurekAlert!
Poorly managed marine fisheries are in trouble around the world, researchers say, while ecosystem-based management is a powerful idea that in theory could help ensure sustainable catches -- but too often there's a gap in translating broad concepts into specific action. To address that, one expert today modified a very old set of rules and issued "Ten Commandments" for ecosystem-based fisheries science, in a presentation at the annual meeting of the American Association for the Advancement of Science.

- Is nutrient loading a smaller problem than we think?
07-24-2007 · EurekAlert!
A recent journal article in Estuaries and Coasts suggests that the problems with coastal sea grass destruction may not be so much due to eutrophication, as is commonly believed, but due to the depletion of top-level consumers in coastal and estuarine ecosystems. This paradigm could have major repercussions for management of coastal ecosystems, considering the research and management emphasis of recent decades on nutrient control.

- The fisherman is a predator like any other
06-05-2007 · EurekAlert!
IRD scientists and their partners of the Peruvian Institute of the Sea have analyzed these data obtained from commercial fishing vessels using mathematical trajectory models in order to elucidate the spatial interactions between fishermen and fish. Spatially, the fishermen behave just like natural predators. Fishermen are indeed part of this ecosystem, obeying laws of behaviour common to other top predators. These findings emphasize the importance of establishing an ecosystem-based concept of fisheries management.

- Changes in west coast marine ecosystems significant
02-16-2007 · EurekAlert!
The California Current system has experienced significant changes during the past decade, resulting in dramatic variations in the ecosystem, characterized by shifts in phytoplankton production, expanding hypoxic zones, and the collapse of marine food webs off the western coast of the United States. These changes, driven by new wind patterns, are consistent with predictive models of global climate change.

- It's official: The carbon crisis is lethal for coral reefs
12-13-2007 · EurekAlert!
Major new research indicates that coral reefs won't survive the rapid increases in global temperatures and atmospheric CO2 forecast by the IPCC. The livelihoods of 100 million people living along the coasts of tropical developing countries will be among the first casualties. Marine scientists argue for drastic action by world leaders on CO2 emissions. Immediate use of proven policy and management tools to address over-fishing, pollution and unsustainable coastal development is critical to saving coral reefs.

- Report highlights progress toward ecosystem sustainability in fish management
07-24-2007 · EurekAlert!
A new report says the key to success in moving toward ecosystem management of our marine fisheries is to build on existing programs in a deliberate fashion and with increased scientific research necessary to support sound decisions. That's the conclusion of the report "Sea Change: Ecological Progress in US Fishery Management," released today by the Marine Conservation Alliance.

- More comprehensive analysis of Klamath River basin needed to aid decision makers
11-28-2007 · EurekAlert!
Two recent scientific studies attempt to better understand the Klamath River basin ecosystem. However, a new report from the National Research Council says for the studies to prove more useful for decision makers, a comprehensive analysis of the basin should be completed to identify all research and management needs.

- 'Nonlinear' ecosystem response points to environmental solutions
01-17-2008 · EurekAlert!
The preservation of coastal ecosystem services such as clean water, storm buffers or fisheries protection does not have to be an all-or-nothing approach, a new study indicates, and a better understanding of how ecosystems actually respond to protection efforts in a "nonlinear" fashion could help lead the way out of environmental-versus-economic gridlock.

- Scientists outline novel approach to ecosystem management
01-31-2008 · EurekAlert!
A team of scientists present a new approach to management efforts in a paper posted this week on Frontiers e-View, the online pre-press publication site of Frontiers in Ecology and the Environment, published by the Ecological Society of America. The researchers suggest that such efforts should focus less on restoring ecosystems to their original state and more on sustaining new, healthy ecosystems that are resilient to further environmental change.
