地理涵蓋範圍

Data were collected in an area of 62,500 ha corresponding to 25 5x5 km squares around the lower Sabor river affected by the Sabor Dams (impact area), and in an additional area of 30,000 ha not directly affected by the dams, encompassing a set of 12 5x5 km squares (control area).

分類群涵蓋範圍

The taxonomic coverage of this dataset spans 1 class, 1 order, 4 families, 10 genera and 17 species positively identified.

時間涵蓋範圍

計畫資料

The dataset contains records of bats (Chiroptera) collected in the region surrounding the lower valley of River Sabor, in the scope of the Ecological Monitoring Program (PME) of the Baixo Sabor Hydroelectric Dams (AHBS), promoted by EDP – Energias de Portugal, S.A. Data were collected between August 2008 and September 2014, during field visits to 97 sampling sites located in the area to be flooded by the reservoirs and within a 5-km buffer around the reservoirs considering the full storage levels of the dams. The occurrence of the target taxa was documented through 4931 observation events. In total, 17 taxa were identified up to the species rank. The “species complexes” could potentially add 7 or more species to the list. The most common species (>400 records) identified were Pipistrellus kuhlii (726 presence records), Pipistrellus pipistrellus (510) and Tadarida teniotis (402). More than 1680 records could not be attributed to any particular species, genus or "species complex", and were thus identified only to the Order taxonomic level.

取樣方法

Sampling was designed to cover the dominant habitats occurring in the study area and that are normally used by foraging bats. A total of 97 sampling points was surveyed, stratified by habitat, considering the main habitat types represented in the region. Of these, 50 sites were located within the area flooded by the reservoir, 26 in areas above or around it, but outside its range of influence (2-5 km), and 21close to extant and future weirs in the tributaries of the River Sabor (above the flooded area). Each sampling site was visited once or twice per season, considering three seasons: spring (April-May), reproduction (July-August) and post-breeding (September-October). Sampling was carried out when there were 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 10 minutes. 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 were 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. In the context of this work, whenever it was not possible to perform the identification to the species level , the binomials, multinomials or genera to which the identification was possible were considered to be present. Thus, the presence of all species constituting these phonic groups (or “species complexes”) was considered possible.
