| Sumario: | The Straits of Gibraltar has one of the highest levels of shipping traffic in the world; consequently, it runs a high risk of suffering ecological disaster. The main objective of the present study was to delimit areas sensitive to anthropogenic perturbations according to information gathered from midlittoral macrophytobenthic communities. We focused mainly on species richness, which was comparatively higher at the North Bay stations, examining similarities among stations using classification and ordination analyses, together with β diversity indices. Both the ordination and classification analyses discriminated between the stations based on their geographical location, and confirmed the Atlantic influence in the North Bay and the Mediterranean influence in the South Bay. Three levels of different environmental sensitivity were established for priorities in future conservation. The westernmost region of the North Bay, together with the eastern zone (transitional area between the two bays), are those having the highest ecological value and vulnerability. The South Bay can be divided into an area with low ecological value, close to Moroccan waters, and an area with intermediate characteristics. |
