Methods

Stream benthic macroinvertebrates have been collected for a period of 6 consecutive years (2010-2015, from April to September, during the glacial melting) along a longitudinal transect of the Saldur stream, a near pristine glacier-fed stream located in South Tyrol, Italy (46°N, 10° E), part of the International Long Term Ecological Research (ILTER) network (site code: LTER_EU_IT_100). Organisms were collected through Surber samplings (0.0506 squared metres, mesh size 500 µm) in 3 sites at different elevation and distance from the glacial source: Saldur 1 (2,030 m a.s.l.; 4.962 km), Saldur 2 (2,016 m a.s.l.; 5.325 km), Saldur 3 (1,645 m a.s.l.; 11.123 km).” [Extracted from Bottarin & Scotti, 2019] For each sampling occasion at each site, we randomly collected 12 Surber samples (0.0506 square metres, mesh size 500 µm) covering all the main substrate typologies present, that were previously examined and estimated. All samples were labelled and preserved in the field with 70% ethanol. Once in the laboratory, the samples were sorted and identified. All the sampled invertebrate organisms were considered in the study. Macroinvertebrates were identified to family or genus level referring to Sansoni and Ghetti (1998). Sampling campaigns were carried out in 6 consecutive years (2010 - 2015), during the glacial melt period (April - September). Depending on the specific years, 5 to 6 samples per year were collected, thus keeping a monthly resolution for the dataset.” [Extracted from Scotti, Tappeiner & Bottarin, 2019] Additional: abundance units are density (ind/m2)
