The ECOMAN project: A novel approach to defining sustainable ecosystem function

Area of Science:

• Marine biology
• Ecotoxicology
• Environmental science

Background:

• Coastal systems face environmental degradation linked to chemical contamination.
• Existing assessment techniques often lack pragmatism and direct links to causes.
• There is a need for cost-effective, evidence-based methods to evaluate ecosystem health.

Purpose of the Study:

• To develop and validate an integrated suite of biological responses (biomarkers) for assessing coastal ecosystem health.
• To link environmental degradation to its causes using organismal condition.
• To provide a pragmatic approach for evaluating chemical contamination impacts.

Main Methods:

• Evaluated sub-lethal endpoints across molecular, cellular, and physiological levels.
• Assessed biomarkers in diverse coastal organisms (filter feeders, grazers, predators) from various habitats.
• Conducted laboratory studies to determine species sensitivity to contaminants.
• Validated biomarker responses in field studies across contaminated and clean ecosystems.

Main Results:

• A suite of cost-effective and environmentally valid biomarkers was identified.
• Biomarkers demonstrated sensitivity to common contaminants in key coastal species.
• Field studies successfully used multivariate statistical analysis to differentiate between contaminated and clean sites.
• The integrated approach effectively assessed organismal health in relation to contamination.

Conclusions:

• A holistic, integrated biomarker approach is a practical tool for assessing chemical contamination impacts.
• This method allows for the evaluation of organismal health and the ranking of marine ecosystem status.
• The ECOMAN project provides a robust framework for pragmatic coastal ecosystem health assessment.
