EDP Baixo Sabor: Phytobenthos – Ecological Monitoring Program [2012]

Description

Enregistrements de données

Les données de cette ressource données d'échantillonnage ont été publiées sous forme d'une Archive Darwin Core (Darwin Core Archive ou DwC-A), le format standard pour partager des données de biodiversité en tant qu'ensemble d'un ou plusieurs tableurs de données. Le tableur de données du cœur de standard (core) contient 23 enregistrements.

1 tableurs de données d'extension existent également. Un enregistrement d'extension fournit des informations supplémentaires sur un enregistrement du cœur de standard (core). Le nombre d'enregistrements dans chaque tableur de données d'extension est illustré ci-dessous.

Cet IPT archive les données et sert donc de dépôt de données. Les données et métadonnées de la ressource sont disponibles pour téléchargement dans la section téléchargements. Le tableau des versions liste les autres versions de chaque ressource rendues disponibles de façon publique et permet de tracer les modifications apportées à la ressource au fil du temps.

Couverture géographique

Data were collected along the lower Sabor river valley, from the mouth to the Maçãs river, about 70 km upstream, as well as in the Vilariça stream, in the municipalities of Torre de Moncorvo, Alfândega da Fé, Mogadouro, Macedo de Cavaleiros, Bragança and Vimioso.

Couverture taxonomique

The taxonomic coverage of this dataset spans 1 phylum, 3 classes, 15 orders, 23 families, 32 genera and 78 species/infra-specific categories.

Couverture temporelle

Données sur le projet

The dataset contains records of Phytobenthos collected in the lower valley of River Sabor (NE Portugal) in the scope of the long-term Ecological Monitoring Program (PME) of the Baixo Sabor Hydroelectric Dams (AHBS), promoted by EDP – Energias de Portugal, S.A. Data were collected in May 2012, during field visits to 23 sampling stations located along the lower Sabor valley up to 70 km upstream of the river mouth, and in the Vilariça stream. The occurrence of the target taxa was documented through 9552 records of species presence and number of individuals (valves). The most abundant taxa (>500 individuals) were Achnanthidium minutissimum (2164 individuals), Gomphonema pumilum (801), Fragilaria capucina vaucheriae (731) and Nitzschia inconspicua (505).

Méthodes d'échantillonnage

Five hard and submerged stones were scraped with a brush at each sampling point (composed sample totaling 100 cm2). The stones were selected at random in turbulent flow zones, preferably not shaded, among those that had a brownish tint film (with diatoms) and excluding all that were covered with filamentous algae. All procedures followed the guidelines recommendations of INAG technical documents (INAG, 2008). Some drops of fixative (Lugol solution 0.33%) were used, until the sample acquired a strong tea color, to fix and preserve the samples. The recommendations of Sournia (1978) for the sample treatment and study were also followed. Before proceeding to the taxonomic identification, samples were processed according to standard protocols (APHA et al., 1989; Sournia, 1978; Krammer and Lange-Bertalot, 2000) and methodologies of reference (APHA et al., 1989; Sournia, 1978; Lund et al., 1958). For the identification of the microalgae, several Floras (Germain, 1981; Krammer and Lange-Bertalot, 1986-1991; 2000; Lange-Bertalot, 2001; Round et al., 1990; Simonsen, 1987; Sims, 1996) and the IBD manual (Prygiel & Coste, 2000), were used. All individual valves were counted under an optic microscope, and identified to the lowest possible taxonomic category.(species level and / or infra-categories) specific). Whenever was necessary, a scanning electron microscope (JEOL JSM 6301) after adequate sample preparation was used (Lund et al., 1958; Sournia, 1978). The results were expressed as relative abundances (number or percentage of valves).
