EDP Baixo Sabor: Bat Feeding Habitats [acoustic sampling] - Ecological Monitoring (PME) and Compensatory Measures (PMC) Programs: Reservoir Filling and Operation Phase (2015-2020)

The dataset contains records of bats (Chiroptera) collected in potential feeding habitats along the lower valley of River Sabor, in the scope of the Ecological Monitoring (PME) and Mitigation/Compensation Measures (PMC) Programs of the Baixo Sabor Hydroelectric Dams, promoted by EDP – Energias de Portugal, S.A.
Sampling was carried out between June 2015 and August 2020 in selected sampling points, in the framework of the regular monitoring of feeding habitats for Chiroptera and as part of the monitoring program of Compensatory Measures (MC5.7). The latter sampling was made in the framework of other Compensatory Measures to generally recover important habitats, that are also suitable for bat feeding. These included riparian galleries, autochthonous forests and new weirs. Overall, regular field sampling was performed at a total of 70 sampling points (impact and control sites) within a 5-km radius buffer around the limits of the area flooded by the reservoirs in the lower valley of River Sabor. The presence and identity of bat species were assessed by acoustic sampling of the echo-location calls emitted in fligth. The records include taxa identified at the species, genus, family or order level, as well as groups of species that share similar calls but cannot be identified to any taxonomic level, and that were thus assigned to acoustic “species complexes”. From a total of 527 recording sessions, 1,544 records of bats were obtained, belonging to 12 identified species and 10 “species complexes”.

本数据集收录了在萨博尔河下游潜在觅食栖息地采集到的蝙蝠（翼手目）记录，这些采集活动是在埃斯德帕-葡萄牙能源公司（EDP – Energias de Portugal, S.A.）推动的萨博尔河下游水电站生态监测（PME）和减缓/补偿措施（PMC）项目框架下进行的。采样活动于2015年6月至2020年8月间在选定采样点进行，旨在对翼手目动物的觅食栖息地进行常规监测，并作为补偿措施（MC5.7）监测计划的一部分。后者采样是在其他补偿措施框架下进行的，旨在恢复对蝙蝠觅食至关重要的栖息地。这些栖息地包括河岸走廊、原生森林和新的水坝。总体而言，在萨博尔河下游水库淹没区域边缘5公里半径缓冲区内，共进行了70个采样点（影响区和控制区）的常规野外采样。蝙蝠物种的存在和身份通过对其飞行中发出的回声定位叫声进行声学采样进行评估。记录包括在物种、属、科或目水平上识别的物种，以及那些叫声相似但无法识别到任何分类水平的一组物种，因此被归入声学“物种复合体”。在总共527次录音过程中，获得了1544条蝙蝠记录，涉及12个已识别物种和10个“物种复合体”。
