Indicators of Status and Change within North Pacific Marine Ecosystems: A FUTURE Workshop
Timing: April 26–28, 2011
Location: East-West Center, Honolulu, Hawaii, U.S.A.
This workshop will be held in the Asia Room at the East-West Center (EWC)
on the University of Hawaii campus, bus transportation between the Ala
Moana Hotel and the venue will be provided.
Conveners: Thomas Therriault (AICE-AP; Canada), Jacquelynne King (COVE-AP; Canada) and Sachihiko Itoh (Japan)
Workshop Description
Ecosystems are affected by a number of natural stressors and, more recently,
an increased number of anthropogenic ones. Ultimately, these stressors
result in changes to ecosystem structure and function, which in turn can
affect their overall productivity and the societies that depend on them.
Metrics of ecosystem status are required to measure impacts of stressors
and monitor change. Ecosystem indicators also could be used to identify
systems that are resilient or vulnerable to stressors.
One of the themes of the PICES FUTURE Science Plan focuses on ecosystem resiliency and vulnerability to stressors and how these attributes might change in the in the future. In order to ensure scientists have the ability to detect ecosystem-level changes in a consistent and standardized way, common metrics must be developed. Further, in an attempt to understand the amount of inherent variability in marine ecosystems, these metrics also need to incorporate measures of uncertainty that can be conveyed to end users, including managers and policy makers.
The goals of this workshop will be to identify:
1) means of determining ecosystem resilience or vulnerability;
2) ecosystem-level indicators of status and change, including but not
limited to fisheries-based indicators;
3) methods to characterize uncertainty in these indicators;
4) common ecosystem indicators to be used for regional comparisons by
the PICES’ community.
Please review the FUTURE Science Plan prior to this workshop (FUTURE). It outlines the key research questions (on pages 3-4) that underlie the objectives of this workshop.
