地理涵蓋範圍

The data were collected within a 15-km buffer around the valley of the River Tua (Northeast Portugal), up to 50 km from the mouth, in the municipalities of Carrazeda de Ansiães, Vila Flor, Mirandela and Sabrosa.

分類群涵蓋範圍

The taxonomic coverage of this dataset spans 1 phylum, 1 class, 1 order, 3 families, 4 genus and 9 species positively identified.

時間涵蓋範圍

計畫資料

The dataset contains records of bats (Chiroptera) collected in roosts along the lower Tua River, and included in the Baseline (2008-2009) and Complementary (2010) Studies of the Environmental Impact Assessment of the Foz Tua Hydroelectric Dam, promoted by EDP – Energias de Portugal, S.A. Data were collected between November 2008 and April 2010, during field visits to 27 known or presumed bat roosts (caves, mines, tunnels, bulidings, etc) used for hibernation and/or reproduction, within a 15-km buffer around the River Tua lower valley. The occurrence of the target taxa was documented through 907 observation events. In total, 11 taxa were identified, of which nine to the species rank and one to the genus rank. The “species complexes” of Myotis could potentially add 2 more species to the list. The most common species (>100 records) were Miniopterus schreibersii (357 records) and Myotis nattereri (207 records). The species complex of the “large” Myotis (Myotis myotis and M. blythii), with 120 records, was also significant. 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 known and presumed bat roosts in the study area, including railroad tunnels, caves, mines, wells and all sorts of abandoned or little used buildings. A place was considered to be a roost when the presence of bats was confirmed, either by direct observations or by indirect evidences (eg., faeces, urine stains, etc.). Each roost was visited once in winter (January-February, hibernation period) and once in spring (April, reproduction period) of 2010. In 2008-2009, only a subset of the sites (railroad tunnels) were visited. All potential roosts were searched for the presence of bat colonies by two observers, which recorded all individuals of each species detected. The time spent in each refuge varied according to 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. When the visual identification raised doubts, or the numbers present were too large to be identified in a suitable time, photographs were taken to be identified later. Sometimes, reliable counts were not possible (e.g. due to the packing of the groups), so only the presence of the species was recorded.
