Registros de Dados

Os dados deste recurso de evento de amostragem foram publicados como um Darwin Core Archive (DwC-A), que é o formato padronizado para compartilhamento de dados de biodiversidade como um conjunto de uma ou mais tabelas de dados. A tabela de dados do núcleo contém 907 registros.

Também existem 1 tabelas de dados de extensão. Um registro de extensão fornece informações adicionais sobre um registro do núcleo. O número de registros em cada tabela de dados de extensão é ilustrado abaixo.

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.

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.

Cobertura Taxonômica

The taxonomic coverage of this dataset spans 1 phylum, 1 class, 1 order, 4 families, 8 genus and 13 species positively identified.

Cobertura Temporal

Dados Sobre o Projeto

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.

Métodos de Amostragem

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.
