Description
Data were collected as part of the National (COFIN) project ‘Assessment of anthropogenic influences on assemblages of algae and invertebrates of rocky shores’. The algae assemblages and invertebrates next to a marina were compared to those of reference shores, to evaluate if the assemblages differ in composition and abundance more
This dataset is about intertidal rocky shore assemblages on a shore next to a marina (Porto Ercole, NW Mediterranean, 42°23'.35N, 11°12'.23E) and on an adjacent exposed shore
3 Sites (stretches of shore 30-50 m long, hundreds of m apart) were sampled in each Shore, at Midshore and Lowshore level
8 Replicates (visual counts on 20x20 cm quadrates) were sampled in each Site
Sampling was repeated at 10 different dates
Taxa were identified at the most detailed level of taxonomic resolution achievable by the naked eye by projecting photographs onto a grid
Data are percentage cover (sessile organisms) or number of individuals (mobile animals) of each taxon in each quadrate
