|Abstract: ||Differences in the structure and functioning of intensively urbanized vs. less human-affected systems are reported,
but such evidence is available for amuch larger extent in terrestrial than in marine systems.Weexamined the
hypotheses that (i) urbanization was associated to different patterns of variation of intertidal assemblages between
urban and extra-urban environments; (ii) such patterns were consistent acrossmainland and insular systems,
spatial scales from 10s cm to 100s km, and a three months period. Several trends emerged: (i) a more
homogeneous distribution of most algal groups in the urban compared to the extra-urban condition and the opposite
pattern of most invertebrates; (ii) smaller/larger variances of most organisms where these were, respectively,
less/more abundant; (iii) largest variability of most response variables at small scale; (iv) no facilitation of
invasive species by urbanization and larger cover of canopy-forming algae in the insular extra-urban condition.
Present findings confirmthe acknowledged notion that futuremanagement strategieswill require to include representative
assemblages and their relevant scales of variation associated to urbanization gradients on both the
mainland and the islands.|
