説明
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”.

プロジェクトデータ
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 occurrence of the target taxa was documented through 1,544 observation events. In total, 12 taxa were identified at the species level. The “species complexes” could potentially add 6 species to this list. The most common species (>100 records) identified were Pipistrellus pipistrellus (332 presence records), Pipistrellus kuhlii (276) and Tadarida teniotis (181). More than 30 records could not be attributed to any particular species, genus or "species complex", and were thus identified only to the Order taxonomic level.

| Study Area Description | The study was conducted in part of the sub-basin of river Sabor, directly or indirectly affected by the construction of the Baixo Sabor Hydroelectric Dams, as well as in control areas nearby. The sampling framework included 40 sites (10 impact and 30 control) located in several habitats near the flooded area (PME), as well as 30 sites in habitats subjected to recuperation/recovery (PMC), in a radius of 5 km around the reservoirs at the full storage level of the dams, encompassing a river extension of 90 km upstream of the mouth. |
| 研究の意図、目的、背景など（デザイン） | The objective of the study was to monitor the importance of selected habitats for bats' feeding, during the reservoir filling (2015) and the beginning of the exploration (2015-2020) phases of the Baixo Sabor Hydroelectric Dams (AHBS). The study was conducted in the area to be flooded by the reservoirs and within a 5-km buffer of the reservoirs at full storage level of the dams. Sampling was also carried out in areas being recovered in the framework of other compensatory measures (weirs, riparian galleries, autochthonous woods) to assess the effectiveness of these recovery to the bats feeding (MC5.7). |

収集方法
Sampling was designed to cover the dominant habitats of the study area, normally used by foraging bats. A total of 70 sampling points (10 impact and 30 controls, for the PME and 30 survey points for the PMC) was surveyed. The impact points were selected among those surveyed in the previous phases, and the subset of the points already established under the monitoring program of the compensatory measures MC1, MC2 and MC3 were also used as control points for bat activity. Each sampling site was visited once per month during the main bat activity period (June-August). In each month, one third of the control points (10 points) were covered, along with the impact points. Sampling was carried under favourable weather conditions, including temperature above 10º and absence of strong winds and rainfall. Acoustic sampling started at sunset and ended 2-3 hours later. Each site was sampled for 15 minutes. In all sites, the air temperature, relative humidity and wind velocity (m/second) were recorded, independently of the confirmed presence of bats. The detection of specimens in flight was made with a bat detector (Pettersson Elektronik, D240X model), with a frequency range of 10-120 kHz. The detector was connected to an automatic digital recorder (model Sony ICD-PX312) which saved the recordings in a “Wave” format, at a frequency of 44 kHz and at an expanded mode of 10x, making them audible to the human ears while, at the same time, preserving the original acoustic characteristics. The analysis of the acoustic records was performed using the sound analysis program BatSound Pro (Pettersson Elektronik AB). This program generates graphs (oscillogram, sonogram and power spectra) using the various sound variables that allow the identification of species or complexes of species detected. The exact identification of the bat species by sound analysis is not always possible, due to problems in detectability and/or identifiability. Whenever it was not possible to perform the identification to the species level, all the compatible species within these phonic groups (or “species complexes”) were considered as with possible occurrence.
| Study Extent | The study was carried out in the Sabor Lower River Valley (Northeast Portugal). The data were collected at sampling sites located in several habitats, both in the area to be flooded by the reservoirs and within a 5-km buffer around the flooded area by the reservoirs at the full storage level of the Sabor dams, encompassing a river extension of 90 km upstream of the mouth. Sampling was carried out in the municipalities of Torre de Moncorvo, Alfândega da Fé, Mogadouro, Macedo de Cavaleiros, Vimioso and Bragança |
