時間涵蓋範圍

計畫資料

The dataset contains records of the Cabrera vole (Microtus cabrerae) and similar species of the class Rodentia and Soricomoprha collected in plots along the lower Tua River, included in the Ecological Monitoring Program (2021-2023) of the Foz Tua Hydroelectric Dam, promoted by EDP – Energias de Portugal, S.A. Data were collected between June and November 2021 during field visits to 50 known or presumed colonies of the species within a 3-km buffer around the River Tua lower valley (Only the sites with positive records (25) were included). The occurrence of the target taxa was documented through 100 observation events distributed among the 32 known or potential occupied colonies. In total, five taxa was identified, at genus (3) or species levels. Microtus cabrerae was the most abundant species (81 indirect observations/signs of presence), followed by Micotus lusitanicus (10), Crocidura russula (3) and Apodemus sylvaticus (1), and Mus sp. (3). Non-identifiable/contaminated scats (42) were assessed to the order only.

取樣方法

Sampling was designed to cover all sites with potential habitats for the Cabrera vole (fallows, bushes, riverine habitats with herbaceous vegetation) located in a buffer of 3 km around the lower Tua valley affected by the Foz Tua dam. All areas surveyed during the previous phases of the project (EIA and Baseline Studies) that were not flooded (50) were included. These areas, were prospected for indirect signs of the Cabrera vole presence (number of tracks, faeces or latrines, and heaps of grass clippings) in spring/summer (June) and autumn (November) of 2021. In each known or potential area surveyed, a detailed description of all the relevant biotopes was performed. This description included (a) the type of biotope, (b) the height of vegetation, (c) the characteristics of the landscape surrounding the demarked areas, namely in relation to the land-use and disturbance. Any changes in these parameters observed between sampling periods were recorded. This description (not included in this dataset), linked with the type of evidences found, was used to classify each area in one of five possible cases: (a) confirmed colony (active and occupied colony of M. cabrerae), (b) confirmed but unoccupied colony (absence of recent evidence in a colony previously identified by molecular tools), (c) potential colony (with evidences of possible, but not (genetically) confirmed, presence of the target species, like tracks and heaps of grass clippings), (d) potential habitat (patches with suitable habitat but without recorded evidences), and (e) no habitat (habitat patches currently without suitable conditions to the occurrence of the species – eg., agriculture or plowed terrain, flat areas without herbaceous cover, riverbeds, with no confirmed occurrences of the species). All faecal samples found in each visit to a colony were collected for subsequent genetic analysis (mitochondrial gene cytocrome-b) in a dedicated laboratory in CIBIO-InBIO (non-invasive samplings), using specific protocols to extract, sequence and analyze the resulting DNA information. This dataset only provides information about the faeces collected (and subjected to molecular analysis) along the study period, thus excluding the “subjective” evidences (tracks, heaps…). Thus, in all, only 25 of the 50 surveyed sites were really useful to assess the occurrence of the species.
