EDP Foz-Tua: Large and Medium-sized Mammals (transects): Complementary Studies [2010]

Data Records

The data in this sampling event resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 130 records.

1 extension data tables also exist. An extension record supplies extra information about a core record. The number of records in each extension data table is illustrated below.

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.

Geographic Coverage

The data were collected within a 5-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, Alijó, Vila Flor, Murça and Mirandela.

Taxonomic Coverage

The taxonomic coverage of this dataset spans 1 phylum, 1 class, 3 orders, 5 families, 8 genera and 8 species.

Temporal Coverage

Project Data

The dataset contains records of large and medium-sized mammals (Mammalia: Carnivora, Cetartiodactyla and Lagomorpha) collected in transects along the lower Tua River, and included in the Complementary Studies of the Environmental Impact Assessment of the Foz Tua Hydroelectric Dam, promoted by EDP – Energias de Portugal, S.A. Data were collected between February and March 2010, during field visits to 40 transects (20 diurnal and 20 nocturnal) with favourable habitats for the target species within a 5-km buffer around the lower Tua River valley. The occurrence of the target taxa was documented through 119 observation events in 24 sampling transects (20 diurnal and four nocturnal). In total, eight taxa were identified to species rank. The most abundant species (>10 signs of presence) were Vulpes vulpes (60), Sus scrofa (21) and Mustela nivalis (11).

Sampling Methods

Sampling was designed to cover the main habitat types for the target mammal species in and around the lower Tua River valley affected by the Foz-Tua dam (including the reservoir area). Each transect was visited once in the winter (February-March) of 2010. All habitats were searched for identifiable signs of presence (scats, tracks, rooting/rummages) of the target species, or live individuals (in nocturnal transects). Species identifications were made in situ, with the help of appropriate field guides.
