Abstract

WALLENSTEIN, Francisco M. et al. Indices to monitor coastal ecological quality of rocky shores based on seaweed communities: simplification for wide geographical use. RGCI [online]. 2013, vol.13, n.1, pp.15-25. ISSN 1646-8872.  https://doi.org/10.5894/rgci365.

This study focuses on intertidal rocky shore seaweed community features used for the assessment of ecological quality of coastal water bodies for the Water Framework Directive (WFD). An alternative index to those developed in the British Isles, in northern Spain and in mainland Portugal is proposed. Results from the application of all indices to a dataset collected on Azorean shores are compared and the suitability of the features used in each index discussed. The features included in the proposed index were selected to allow its applicability throughout a large geographic area.

Keywords : Ecological quality; macroalgae; intertidal; index comparison; wide geographic use.
