Ecosystem-Based Quality Index in a harbor bay: Assessing the status of a heterogeneous system in a functional framework at a local scale

The assessment of natural ecosystem status is a fundamental premise to enable environmental management at local scales to maintain ecosystem functioning, services and resilience. Ecologists have developed many biological and environmental indices to inform and support environmental management and po...
