EDP Baixo-Sabor: Phytobenthos – Ecological Monitoring Program [2015-2019]

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 15 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 in the Sabor lower valley (Northeast Portugal), in the municipalities of Mogadouro and Macedo de Cavaleiros.

Taxonomic Coverage

The taxonomic coverage of this dataset spans 2 phyla, 3 classes, 14 orders, 24 families, 45 genera, and 122 species and infra-specific categories.

Temporal Coverage

Project Data

The dataset contains records of Phytobenthos (Diatoms) collected in the watershed of River Sabor, and included in the Ecological Monitoring Program (2015-2019) of the Environmental Impact Assessment of the Foz Tua Hydroelectric Dam, promoted by EDP – Energias de Portugal, S.A. Data were collected in spring/summer (June-July) of 2015-2019 during field visits to three sampling plots located upstream the dam reservoir. The occurrence of the target taxa was documented through 8449 records of species presence and number of individuals (valves). The most abundant species (> 200 individuals) were Cocconeis euglypta (1144), Fragilaria capucina (304), Navicula lanceolata (284), Cymbella affinis (230) and Achnanthidium minutissimum (220).

Sampling Methods

Epilitic communities were sampled in accordance with the Sampling Protocol and analysis for phytobenthos - diatoms (INAG 2008). In each sampling point a number of stones totaling a colonized surface of ≈100 cm2 was examined, avoiding, whenever possible, the shaded areas, as well as the areas without current or with very high water velocity. All samples were fixed “in loco” with commercial formaldehyde (37%) and brought to laboratory, where they were subjected to the nitric acid method (INAG, 2008). All diatoms present were counted and identified up to the lowest possible taxonomic level using several floras, namely those of Germain (1981) and Krammer and Lange-Bertalot (1986, 1988, 1991a and 1991b), as well as the IBD manual (Prygiel and Coste, 2000).
