This dataset contains occurrence records of infralittoral molluscs from several locations in the Mediterranean basin. These data come from available data, published papers in scientific journals as well as free available PhD thesis, dating back to 1969.

These data were part of a study investigating the general statement that Marine Protected Area’s (MPA’s) have an effect on the population and assemblages of benthic organisms in the intertidal zone of rocky shores. The effects were evaluated over a variety of spatial scales

The aim of this study was to describe the species distribution, main algal associations and zonation patterns along the coast of Mjóifjürdur from the head of the fjord and outwards.

Data were part of a research project that wanted - amongst others - to quantify the spatial and temporal variation of the benthic rocky reef assemblages in the Marine Protected Area (MPA) of Capraia Island (Tuscan Archipelago) and a bordering non-protected area.

This study dealt with the biomass of algal settlements at different locations along the Istrian coast in the Northern Adriatic Sea. The eulittoral and upper sublittoral zone of rocky sites was investigated during three subsequent years: 1967, 1968 and 1969.

Data were collected as part of wider coastal management programmes, sponsored by the Norwegian Polar Research Institute. The main purpose of this data collection was to present an ecological inventory of the Svalbard Archipelago and to map the areas of great biological importance.

The purpose of this study was to follow the gradient of the benthic algal vegetation from the head to the mouth of the Borgafjördur. Attention was paid to the zonation patterns, algal associations and the species distribution. These data were also compared to the vegetation of other Icelandic fjords.

The general goal of this study was to test if assemblages of algae and invertebrates of rocky shores next to marinas are different in taxon composition and abundance compared to reference shores far away from this source of disturbance.

This dataset contains records of polychaetes from intertidal rocky shores in the Mediterranean Sea.

Samples of macro- and megafauna were collected in the North Aegean Sea, between 1997 and 1998. This dataset then served as a basis to describe the diversity, spatial and temporal variability and trophic relationships of different taxonomic groups inhabiting hard substrates.
