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>

本数据库收录了意大利奥罗比克阿尔卑斯山（Orobic Alps）塞里奥流域（Serio watershed）5个溪流样地（GU、GD、OU、OD、NN）的调查采集所得的生物与环境数据。<br>在每个溪流样地，研究团队于2020年6月至2021年5月的周期内开展月度采样，共计获取58份样本（12个月×5个样地，其中NN样地2021年5月、OU样地2021年2月的样本缺失）。大型底栖无脊椎动物（Macroinvertebrates）采用索伯网（Surber net，采样面积0.10 m²，网孔500 µm）采集。每份采样记录均报告了各分类群在单次采样中每平方米的个体数量。<br>- Dictyogenus_f. 即Dictyogenus fontium<br>- Perlodes_i. 即Perlodes intricatus<br>- Epeorus_al. 即Epeorus alpicola<br>- Epeorus_as. 即Epeorus assimilis（部分文献将其记为Epeorus sylvicola）<br>- Serratella_i. 即Serratella ignita<br>- Elmidae_A 指 Elmidae 成虫<br>- Elmidae_L 指 Elmidae 幼虫<br>- Scirtidae_L 指 Scirtidae 幼虫<br><br>此外，本数据集同步记录了每次采样时测定的环境变量：<br>- HABITAT：溪流生境可利用度<br>- DISTURBANCE：洪水干扰占比（%）<br>- ALGAE：自生源藻类生物量（g/m²）<br>- CE：电导率（electrical conductivity，uS/cm）<br>- COD：化学需氧量（Chemical oxygen demand，mg/l）<br>- pH：酸碱度<br>- TMean：前30日日均水温（daily mean water temperature of the antecedent 30 days，℃）<br>- CPOM：粗颗粒有机物质（coarse particulate organic matter，g/m²）<br>- O2：氧气饱和度（%）<br>- DO：溶解氧（dissolved oxygen，mg/l）<br>- NNO3：硝态氮（nitric nitrogen，mg/l）<br>- TAmp：水温年变幅（annual water temperature variability，℃）
