Dear Colleauges:
Might I draw your attention to the following theme session at this years
International Council for the Exploration of the Sea Annual Science
Conference?  The meeting will be held in Aberdeen, Scotland from 20-24
Sept.  The abstract deadline is April 25.  For particular questions
about this theme session, please contact:
Maria de Fatima Borges [log in to unmask]

***************************************************
The Spatial Dimension of Ecosystem Structure and Dynamics
       (Session L)

Conveners: Maria Borges (Portugal), Jason Link (USA), and Einar
       Svendsen (Norway)

Questions to address:

Spatial scales of the ecosystem: Downscaling global atmospheric–oceanic
interactions to basin and local habitat scales; Putting spatial pattern
into population and ecosystem models;  Spatial relationships among
biotic communities and their habitat;  The spatial aspects of human
activities

In order to make progress on addressing anthropogenic impacts via
ecosystem-based approaches, we need to recognise that ecosystem
processes occur at multiple scales. Thus, it is essential for
ecosystem-based approaches to examine the multiple spatial and temporal
dimensions on which abiotic, biotic, and human processes occur. Key
developments in coupled physical-biological numerical models still need
to be applied more broadly. Defining habitat across a suite of variables
also poses several challenges, particularly for fisheries issues at
appropriately resolved spatial scales. Recognising that ecosystem
processes operate at multiple temporal and spatial scales is
critical, but incorporating spatial explicitness into ecosystem and
population models remains a key challenge.
