EDP Foz-Tua: Cabrera vole (Microtus cabrerae) & Small Mammals - Baseline Studies [2008]

Dernière version Publié par EDP - Energias de Portugal le Apr 15, 2019 EDP - Energias de Portugal

The dataset contains records of Cabrera vole (Mictotus cabrerae) and other small mammals (Rodentia and Eulipotyphla) collected in the lower valley of the River Tua, included in the Addendum to the Baseline Studies (2008) of the Environmental Impact Assessment of the Foz Tua Hydroelectric Dam, promoted by EDP – Energias de Portugal, S.A. Data were collected between November and December 2008 during field visits to 22 samping points, within habitats favourable habitats for M. cabrerae, on the area of the lower Tua valley directly or indirectly affected by the Foz Tua dam. The presence of individuals was recorded by capture with Sherman traps. The identification of the individuals attributed to the genus Microtus was confirmed by molecular analysis.

Données sur le projet

The dataset contains records of the Cabrera vole (Microtus cabrerae) and other small mammals (Rodentia and Eulipotyphla) collected in plots along the lower Tua River, included in the Addendum to the Baseline Studies of the Environmental Impact Assessment (2008) of the Foz Tua Hydroelectric Dam, promoted by EDP – Energias de Portugal, S.A. Data were collected between November and December 2008 during field visits to 22 sampling points with favourable habitats for the Cabrera vole (fallows, bushes, riverine habitats with low vegetation) within a 5-km buffer around the River Tua lower valley. The occurrence of the target taxa was documented through 238 capture events in 22 sampling points. In total, five taxa were identified, all to the species rank. The most abundant species were Apodemus sylvaticus (115 observation/capture events), Crocidura russula (50), Microtus lusitanicus (36) and Mus spretus (31).

Description du domaine d'étude / de recherche The study was conducted in part of the sub-basins 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 was centered in suitable habitats to the Cabrera vole (fallows, bushes, riverine habitats with low vegetation) found in a 5-km radius buffer around the future reservoir banks, and up to 45 km from the Tua mouth.
Description du design The objective of the study was to identify all the potential places of occurrence of the Cabrera vole in a buffer of 5 km around the Tua lower valley, before the dam construction, and to gather quality data to support the design and implementation of mitigation and/or compensation measures.

Méthodes d'échantillonnage

Sampling was designed to cover all the potential habitats of the Cabrera vole (fallows, bushes, riverine habitats with low vegetation) in and around the lower Tua valley affected by the Foz Tua dam. A preliminary selection of suitable places was made using aerial photos and other cartographic means, followed by a visit to the area. A total of 24 areas were initially selected based on the habitat characteristics, but only 20 were actually used for sampling. A total of 25 sampling plots located in 20 of the 24 areas with suitable habitat was surveyed for signs of the presence of microtidae (tracks, faeces, latrines) in November-December 2008. When this inspection was positive, the plot was earmarked for a trapping session, to confirm the presence of Cabrera vole. As a result of this survey, 22 sampling plots were selected for trapping. Each trapping session consisted in the installation of lines of “Sherman” traps distributed every 2 m in all suitable habitats of the sampling plot. The number of traps set at each point depended mainly on its area and the amount of presence signs detected. Traps were baited with apple, carrot and commercial cat food (for Soricidae) and were covered with vegetation carded cotton, to provide food and thermal comfort for captured individuals, respectively. Each trap was controlled at least twice a day (one in the morning and another in the late afternoon). Traps were baited in one day and remained set for more three consecutive days and nigths. All the captured specimens were administered with a light volatile ethyl ether anesthesia, to ensure a correct and safe manipulation procedure. Each specimen was individually assigned a temporary marking (haircut), aiming to recognize the animal in the event of a recapture situation, aged and sexed (with the exception of shrews when non-lactating), measured and subsequently released. The following biometric parameters were taken: body length (mm), tail length (mm), hind leg length (mm), ear length (mm) and weight (grams). All identifications were made with appropriate field guides (Mathias et al., 1998; Palomo and Gisbert, 2002). The dichotomous key of Castells and Mayo (1993) was used to separate the Cabrera vole from other species of microtidae. Whenever possible, a tissue sample (a small portion of the ear) was taken from all captured microtidae to confirm the species identification. This was performed through the amplification and sequencing of a mitochondrial gene, cytochrome b, which has 1140 base pairs (base pairs, bp) and is widely studied in the European populations of Microtus. The DNA of all collected Microtus samples was extracted using a Extraction kit ("Qiagen Dneasy Tissue Kit"). The sequences obtained were then compared with the sequences available on GenBank. The captures were carried out under the License No 176/2008/CAPT, issued on October 2008, by the Institute of Nature and Forests Conservation (ICNF) to the senior field technician.

Etendue de l'étude The data were collected within a 5-km buffer around the Tua lower valley (Northeast Portugal), up to 45 km from the mouth, and in Ferradosa stream (Douro sub-basin), in the municipalities of Carrazeda de Ansiães, Vila Flor, Murça and Mirandela.
Contrôle qualité All identifications were performed by qualified technicians
