Geographic Description

The data were collected in a single point in the Baixo Sabor reservoir, at a fixed station 1300 m upstream of the dam in the deeper zone of the reservoir.

General Taxonomic Coverage

The taxonomic coverage of this dataset includes 6 kingdoms, 15 phylum, 17 classes, 48 orders, 77 families, 144 genus and 305 species of the list of the EU’s Water Directive framework. The actual observations encompass 5 kingdoms, 9 phylum, 10 classes, 18 orders, 23 families, 30 genus and 31 species. The identification was made, whenever possible, to species level; otherwise, the phylum, class, order, family or genus were specified.

Abstract

The dataset contains Phytoplankton records of samples collected at Baixo Sabor reservoir during the first year of the Ecology Monitoring Program (PME) of Baixo Sabor Hydroelectric Scheme, promoted by EDP – Energias de Portugal, S.A. Samples were collected in the deeper zone of the reservoir, at a fixed station 1300 m upstream of the dam, in 6 campaigns carried out between March and October of 2016. The targeted taxa were phytoplankton species, included as biological quality element for ecological quality in the framework of the EU’s Water Directive. A total of 1849 taxa records were obtained corresponding to 31 species and 11 genera. The most abundant species (>100 records) were Fragilaris crotonensis (phylum Ochropyta, class Bacillariophyceae, order Fragilariales) (198 records), Chroomonas acuta (Cryptophyta, Cryptophyceae, Pyrenomonadales) (167), Woronichinia naegeliana (Cyanobacteria, Cyanophyceae, Chroococcales) (142) and Eudorina unicocca (Chlorophyta, Chlorophyceae, Volvocales) (119), and the genera Anabaena (Cyanobacteria, Cyanophyceae, Nostocales) (122) and Cryptomonas (Cryptophyta, Cryptophyceae, Cryptomonadales) (121).
