The dataset contains abundance and body size data of benthic macroinvertebrates collected in the river Tirso (Sardinia, Italy) during the years 1998-1999. Data refer to 143 taxa and 48248 individuals.

The dataset contains taxonomic and body size data of the benthic macroinvertebrate communities collected in the hydrographic basin of Flumini Mannu - Cixerri (Sardinia, Italy) during the years 1992-1993. Sampling sites were located along two main basins Flumini Mannu and Cixerri, and other smaller coastal basins. Data refer to 98 taxa and 14566 individuals.

Phytoplankton composition and size distribution in the Lago Maggiore (Italy) was analysed in detail measuring the main morphological parameters of the algal cells. This data set allowed to evaluate the morphological plasticity of many species across the seasonal succession.

This dataset provides broad information on taxonomic and morphological (shape, linear dimensions, biovolume, cell abundance, cell size) structure of phytoplankton communities, in an impacted marine coastal area. The study was conducted in order to understand the role of anthropogenic pollution on phytoplankton community. For this reason, 3 different areas, along a pollution gradient, were considering. Data were collected at different spatial and temporal scales, in marine ecosystems, located in South Adriatic Sea, close to an industrial area and a marine protected area, in Brindisi, along Salento Peninsula (Puglia region, Italy).
