NAVIGATING BETWEEN ECOSYSTEM STRUCTURE AND FUNCTIONING IN RESEARCH AND MANAGEMENT; AN OVERVIEW OF CURRENT KNOWLEDGE.
Most biological assessments of surface water quality have been based on structural attributes. The use of functional attributes, such as decomposition, secondary production, nutrient cycling and whole-stream metabolism, to assess water quality have been much less often used. Surprisingly few studies cover a combination of both. Structural and functional attributes can provide complimentary information on ecosystem health. Multiple stressors can affect structure and functioning of ecosystems in different ways, most probably due to different interactions on different trophic levels. Furthermore, changes in species compositions, especially species losses, will alter the rates of ecological processes that are vital to retain inherent ecosystem functions. Above that anthropogenic stress can directly alter ecosystem functioning. The pathways of anthropogenic stress that induce either changes in ecosystem processes or in ecosystem structures could in combination strengthen tools to assess ecosystem integrity and help management in taking accurate measures. We will provide an overview of structural and functional responses under different natural conditions and anthropogenic stress. We will indicate directions in which combined approaches can assist management in making effective decisions.
