EDP Foz Tua: Bat Habitats - Complementary Studies [2010]

最新版本 由 EDP - Energias de Portugal 發佈於 Mar 25, 2019 EDP - Energias de Portugal

The dataset contains records of bats (Chiroptera) collected in the lower valley of River Tua. Data were collected in the scope of the Complementary Studies (2010-2011) of the Environmental Impact Assessment of the Foz Tua Hydroelectric Dam, promoted by EDP – Energias de Portugal, S.A. Data were collected in April 2010 during field visits to 48 points located in suitable foraging habitats for bats, within a 5-km radius buffer around the lower valley of River Tua. The presence and identity of the bat species was assessed by acoustic sampling of the echo-location calls emitted in fligth. The records include taxa identified at the species or genus level, as well as groups of species corresponding to seven acoustic “species complexes”.

計畫資料

The dataset contains records of bats (Chiroptera) collected in suitable foraging habitats along the lower valley of River Tua. Data were collected in the scope of the Complementary Studies (2010-2011) to the Environmental Impact Assessment of the Foz Tua Hydroelectric Dam, promoted by EDP – Energias de Portugal, S.A. Data were collected in April 2010, during field visits to 48 sampling points, stratified by habitat, within a 5-km radius around the lower valley of River Tua. The occurrence of the target taxa was documented through 427 observation events. In total, 12 taxa were identified, 11 to the species rank and 1 to the genus rank. The 7 “species complexes” identified could potentially add 9 more species to the list. The most common species (>20 records) were Pipistrellus pygmaeus (151 records), Tatarida teniotis (60 records), Pipistrellus kuhlii (34 records), Myotis daubentonii (27 records) and Eptesicus serotinus (24 records). The “species complex” Pipistrellus pipistrellus/P. pygamaeus was also relevant, with 61 records.

研究區域描述 The study was conducted in part of the sub-basin of river Tua, prior to the construction and subsequent flooding of the lower part of this river’s valley by the Foz-Tua Hydroelectric Dam. The sampling area covered a radius of 5 km centered in the river margins, up to a length of about 45 km from the Tua mouth.
研究設計描述 The objective of the study was do document the usage of the potential foraging habitats for bats in the river Tua lower valley before the dam construction (river margins, woodlands, shrublands, vineyards, orchards/olive-orchards and urbanized areas), to gather quality data to support the design and implementation of mitigation and/or compensation measures.

Sampling was designed to cover all suitable foraging habitats for bats in the study area. A stratified sampling procedure was used, with the number of samples allocated to each habitat in proportion to the area occupied and/or its significance for bats. A total of 48 sampling points were set in natural woodlands (7), river margins (15), shrublands (7), orchards/olive groves (5), vineyards (8) and urbanized areas (6). Each point was visited once between 8 and 22 April 2010, within ± 3 hours of sunset, and acoustic sampling was carried out for 20 (consecutive) 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 Nomad Jukebox 3, from Creative Technology Ltd.) which saved the recordings in a “Wave” format, at a frequence of 44.1 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 sound records was made in the lab, with the software “Batsound Pro – Sound Analysis”, from Pettersson Elektronik. This software generates graphics (oscillograms, sonograms and power spectrums) that allow the identification of the detected species by comparing them with those available in reference bat sound libraries. The acoustic variables used to identify the sounds are (1) the structure of the pulse, (2) the frequency of maximum energy (kHz), (3) the range of frequencies (kHz), (4) the pulse duration (ms), (5) the interval between pulses (ms), and (6) the pulse repetition rate (Hz). 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, all records that could not be unequivocally attributed to a given species were assigned to the “species complex” that best fitted their frequency characteristics. Thus, 3 multi-specific groups sharing the same acoustic characteristics were considered: Myotis spp. (in turn subdivided in “large” Myotis – M. myotis and M. blythii – and “small” Myotis – the remaining 7 species), Pipistrellus ssp. (several complexes of different combinations of species, including Miniopterus schreibersii, whose vocalization is undistinguishable from that of Pipistrellus pygmaeus), and Nyctalus spp. (N. lasipoterus and N. noctula).
