Spatiotemporal patterns of macroinvertebrate assemblages across alpine streams with contrasted thermal regime

The database contains biological and environmental data collected during a survey carried out across 5 stream sites of the Serio watershed (Orobic Alps, Italy): GU, GD, OU, OD, NN. <br> 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 NN May and OU 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. <br> -Dictyogenus_f. refers to Dictyogenus fontium -Perlodes_i. refers to Perlodes intricatus -Epeorus_al. refers to Epeorus alpicola -Epeorus_as. refers to Epeorus assimilis (or sylvicola depending on the references) -Serratella_i. refers to Serratella ignita -Elmidae_A refers to Elmidae adults -Elmidae_L refers to Elmidae larvae -Scirtidae_L refers to Scirtidae larvae <br> Moreover we reported the environmental variables measured at each sampling: -HABITAT (Stream habitat availability) -DISTURBANCE (Flood disturbance, %) -ALGAE (Autochtonous biomass, g/m2) -CE (electrical conductivity, uS/cm) -COD (Chemical oxygen demand, mg/l) -pH -TMean (daily mean water temperature of the antecedent 30 days, °C) -CPOM (coarse particulate organic matter, g/m2) -O2 (oxygen saturation, %) -DO (dissolved oxygen, mg/l) NNO3 (nitric nitrogen, mg/l) TAmp (annual water temperature variability, °C) <br>
