Data Records

The data in this sampling event resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 80 records. 1 extension data tables also exist. An extension record supplies extra information about a core record. The number of records in each extension data table is illustrated below.

This IPT archives the data and thus serves as the data repository. The data and resource metadata are available for download in the downloads section. The versions table lists other versions of the resource that have been made publicly available and allows tracking changes made to the resource over time.

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 Dam, and in an additional area of 30,000 ha not directly affected by the dam, encompassing a set of 12 5x5 km squares (control area), in the municipalities of Torre de Moncorvo, Mogadouro, Vimioso, Bragança and Miranda do Douro

分類群涵蓋範圍

The taxonomic coverage of this dataset spans 1 class, 1 order, 2 families, 2 genera and 2 species positively identified.

計畫資料

The dataset contains records of bats (Chiroptera) collected in roosts along the lower valley of River Sabor, in the scope of the Ecological Monitoring Program (PME) of the Baixo Sabor Hydroelectric Dams, promoted by EDP – Energias de Portugal, S.A. Data were collected between July 2012 and August 2014, during field visits to 12 selected bat roosts (entrance of caves and mines with restricted access) for hibernation, reproduction and pre-dispersion, within a 5-km radius around the lower valley of River Sabor. The occurrence of the target taxa was documented through 129 observation events. In total, 2 taxa were identified up to the species rank. The “species complexes” could potentially add 3 more species to the list. The two species identified were Rhinolophus ferrumequinum (36 records of presence) and R. hipposideros (30) The “species complexes” of the “small” Myotis (M. mistacinus, M. emarginatus, M. escalerai, M. beschteinii and M. daubentonii) was present in one sampling occasion and the Rhinolophus complex (Rhinolophus euryale and R. mehelyi) in 30. Thirty detections could not be safely attributed to any species or species complexes. Due to the vulnerability of the roost locations, the precision of the geographic coordinates was degraded to 0.01.

取樣方法

Sampling was designed to cover all the bat roosts in the study area that could not be accessed due to security reasons, particularly mines and caves. Each point, located at the entrance of the roost, was visited at least once per season - spring (April-June), reproduction (July) and post-breeding (September-October) - in favorable conditions (temperature above 10º and absence of strong winds and rainfall). Acoustic sampling in each plot was initiated at sunset and had a fixed duration of 90 minutes. The detection of the 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 analyses 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) where 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.
