<b>Spatiotemporal patterns of macroinvertebrate assemblages across mountain streams with </b><b>contrasting thermal regimes</b>

The database contains biological and environmental data collected during a survey carried across 5 stream sites of the Serio watershed (Orobic Alps, Italy) named site A, B, C, D and E.At each stream site, a monthly sampling was carried out during a one-year campaign, from June 2020 to May 2021, providing 58 samples (12 months*5 sites with two missing samples in E May and D February). Macroinvertebrates were sampled with a Surber net (0.10 m², 500 µm mesh). For each taxon the number of individuals/1 m² collected at each sampling is reported.The data have been used in the article: "<b>Spatiotemporal patterns of macroinvertebrate assemblages across mountain streams with </b><b>contrasting thermal regimes</b><b>" </b>written by Luca Bonacina and colleagues published in <i>Freshwater Science</i>.Taxonomic info:Dictyogenus_f. refers to <i>Dictyogenus fontium</i>-Perlodes_i. refers to <i>Perlodes intricatus</i>-Epeorus_al. refers to <i>Epeorus alpicola</i>-Epeorus_as. refers to <i>Epeorus assimilis</i> (or <i>sylvicola</i> depending on the references)-Serratella_i. refers to <i>Serratella ignita</i>-Elmidae_A refers to Elmidae adults-Elmidae_L refers to Elmidae larvae-Scirtidae_L refers to Scirtidae larvaeEnvironmental info:-TMean (daily mean water temperature of the 30 days antecedent of each sampling, °C)-dTday (mean of the daily thermal variation [daily maximum – daily minimum] computed over the 30 d before each sampling occasion)-EC (electrical conductivity, uS/cm)-O2sat (oxygen saturation, %)-DO (dissolved oxygen, mg/l)-pH-NO3-N (nitric nitrogen, mg/l)-COD (Chemical oxygen demand, mg/)-HABITAT (Stream habitat availability calculated with the Shannon index applied to the relative abundance of microhabitats)-DISTURBANCE (Flood disturbance, %)-CPOM (coarse particulate organic matter, g/m²)-ALGAE (Autochtonous biomass, g/m²)<br>
