Descripción
The dataset contains records of bats (Chiroptera) collected in the lower valley of River Tua. Data were collected in the scope of the long-term Ecological Monitoring Program (PME) and the Monitoring Program of Mitigation/Compensation Measures (PMC) of the Foz Tua Hydroelectric Dam, promoted by EDP – Energias de Portugal, S.A. Data were collected between July 2011 and September 2017 during field visits to 91 known or presumed bat hibernation, reproduction and pre-dispersion (post-reproduction) roosts, within a 5-km radius buffer around the lower valley of River Tua. From 2012, two roosts located at >20 km from the river (deactivated railroad tunnels) were added to the sampling sites in the context of the PMC. The presence of individuals was recorded by direct observation, and all individuals were photographed whenever possible. The records include taxa identified at the species or genus level. In several occasions it was not possible to separate the individual species, so they were grouped in 15 “species complexes”, both mono-specific and multi-specific. Due to the vulnerability of the roost locations, the precision of the geographic coordinates was degraded to 0.01, according to the recommendations of Chapman & Grafton (2008). The dataset with the original (undegraded) coordinates may be provided upon request by the resource contact from EDP, who will define the terms and conditions for its use.

Cobertura geográfica
Most data were collected within a 5-km radius buffer around the river Tua valley (Northeast Portugal), up to 36 km from the mouth. There were also two additional sites surveyed at >20 km from the river. The sites were located in the municipalities of Alijó, Carrazeda de Ansiães, Vila Flor, Mirandela, Sabrosa and Bragança.

Datos del proyecto
The dataset contains records of bats (Chiroptera) collected in roosts along the lower valley of River Tua. Data was collected in the scope of the Ecological Monitoring Program (PME) and Program of Mitigation/Compensation Measures (PMC) of the Foz Tua Hydroelectric Dam, promoted by EDP – Energias de Portugal, S.A. Data were collected between July 2011 and September 2017, during field visits to 91 known or presumed bat roosts (caves, mines, tunnels, bridges, bulidings, etc.) for hibernation, reproduction and pre-dispersion, within a 5-km radius around the lower valley of River Tua. The occurrence of the target taxa was documented through 5065 observation events. In total, 15 taxa were identified, 13 to the species rank and 2 to the genus rank. The “species complexes” could potentially add 4 more species to the list. The most common individual species (>100 records) were Miniopterus schreibersii (1662 records), Rhinolophus ferrumequinum (892), R. hipposideros (494), Myotis myotis (456) and M. daubentonii (195). The “species complexes” of the “small” Myotis (M. mistacinus, M. emarginatus, M. escalerai, M. beschteinii and M. daubentonii), with 491 records, and of the “large” Myotis (M. myotis and M. blythii), with 216 records, were also important. Due to the vulnerability of the roost locations, the precision of the geographic coordinates was degraded to 0.01.

Descripción del área de estudio | The study was conducted in part of the sub-basin of river Tua directly or indiirectly affected by the construction of the Foz-Tua Hydroelectric Dam. The sampling included all known and potential roosts located in the flooded area and those found in a 15 km radius buffer around the future reservoir banks (caves, mines, tunnels, buildings, etc.), and up to a length of about 36 km from the Tua mouth. |
Descripción del diseño | Thje objective of the study was to monitor the fate of bats roosts (hibernation and/or reproduction, and pre-dispersion periods) and associated bat populations in the area of the Foz-Tua Hydroelectric Dam, centered in a 5-km radius buffer around the river, during its construction (2011-2015) and subsequent flooding (2016-2017). The objectives also included the monitoring of bat population trends in 2 deactivated railroad tunnels located outside the study area (20 km distant), whose conditions for bats were improved in the scope of the Mitigation/Compensation Program of the Foz-Tua dam (2015-2016). |

Métodos de muestreo
Sampling was designed to cover all known and potential bat roosts in the study area, including railroad tunnels, caves, mines, wells, bridges and all sorts of buildings. A place was considered to be a roost when the presence of bats was confirmed, either by direct observations or by indirect evidences (e.g., faeces, urine stains, etc.). Each roost was visited once or twice per season, in the hibernation (January-February), reproduction (April-August) and pre-dispersion (September-October) periods, depending on the year. All roosts were searched for the presence of bats by two observers, which recorded all individuals seen. The time spent in each roost varied with the number of bats present and the accessibility conditions. Species identification were usually made “in loco”, with the aid of head-torches, binoculars and field guides. All bats were photographed whenever possible, not only to build a photographic database, but also to allow a “a posteriori” identification of individuals that raised doubts, or to count large groups that could not be accurately counted in a suitable time in the field.
