eLTER_SCOTTI_Eurac_IT25 - Val Mazia/Matschertal - Italy

Stream benthic macroinvertebrates have been collected for a period of 8 consecutive years (2010-2017, 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).

研究人员在意大利南蒂罗尔州的萨尔杜尔溪（Saldur stream）纵向样带开展了连续8年的采样工作（2010-2017年，每年4月至9月的冰川消融期），采集该溪流的底栖大型无脊椎动物（benthic macroinvertebrates）。萨尔杜尔溪为近乎原始的冰川补给溪流，地理坐标为46°N、10°E，隶属于国际长期生态研究（International Long Term Ecological Research, ILTER）网络，站点代码为LTER_EU_IT_100。采样采用索伯采样器（Surber sampler），单样采样面积为0.0506平方米，网孔尺寸为500微米。本次采样共设置3处不同海拔、距冰川源头距离各异的点位：Saldur_1（海拔2030米，距源头4.962千米）、Saldur_2（海拔2016米，距源头5.325千米）、Saldur_3（海拔1645米，距源头11.123千米）。
