EDP Foz Tua Large Mammals (nocturnal transects) - Ecological Monitoring Program [2011]

Description

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 56 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 35 km from the mouth, in the municipalities of Alijó, Carrazeda de Ansiães, Murça, Vila Flor and Mirandela.

Taxonomic Coverage

The taxonomic coverage of this dataset spans 1 phylum, 1 class, 2 orders, 3 families, 3 genera and 3 species.

Temporal Coverage

Project Data

The dataset contains records of large mammals (Mammalia) collected in nocturnal transects along the lower Tua River, and included in the Ecological Monitoring Program of the Foz Tua Hydroelectric Dam, promoted by EDP – Energias de Portugal, S.A. Data were collected between June and August 2011, in 24 line transects in areas with favorable habitats for large mammals within a 5-km buffer around the River Tua lower valley. The occurrence of the target taxa was documented through 16 observation events, of which 12 correspond to positive species identifications (10 of Vulpes vulpes, and 2 of Oryctolagus cuniculus).

Sampling Methods

Sampling was designed to cover the main habitat types for large mammals in and around the lower Tua valley affected by the Foz-Tua dam (including the reservoir area). Twenty-four nocturnal transects of an average length of 2000 m (range: 505-3968 m), depending on accessibility by car, were established in 36 2x2 km squares in the flooded area and in a control area upstream. The transects were performed in a 4x4 wheeled vehicle at reduced speed (about 10km / h), using the headlights of the vehicle for frontal observations and a high power focus for lateral observations. Each team was formed by two observers, one driver, accountable for the frontal observations, and one person responsible for the portable spotlight to the sides of the transects. Species identification was made "in loco", if necessary, with the help of appropriate field guides.
