OOS-46:
Ecological indicators at multiple scales
Thursday,
August 11, 8 AM - 11:30 AM, Meeting Room 516c, Level 5, Palais
des congrès de Montréal
Organizers:
Felix Müller (fmueller@ecology.uni-kiel.de),
Eric Hyatt
Description:
Indicator
derivation and application have to be based upon sound scientific concepts and
methodologies. In this context, a key problem emerges from the correct selection
and consideration of spatio-temporal scales, i.e., concerning the relationship
between the indicator itself and the indicated state variables or environmental
targets. Up to now these scale problems and the results of hierarchy theory have
not been integrated into environmental indication sufficiently. Therefore,
within the session new concepts and results will be presented to find solutions
and methods for a better involvement of scale-related issues in the future.
Another important item of environmental indication is the correlation with
environmental targets, such as ecosystem health, integrity, or sustainability.
Especially the demand for sustainability indicators has affected various
interdisciplinary attempts to integrate ecological, social, and economic
components within comprehensive indicator sets. Referring to these
interdisciplinary indicators, the scale problem increases, i.e., because
ecosystem processes and societal dynamics do not operate with identical spatial
extents and temporal characteristics.
