EDP Foz-Tua: Phytobenthos – Ecological Monitoring Program – Exploration Phase [2018-2020]

Citation

Cortes R, Jesus J, Santos C, Lopes M, Pereira E, Múrias T (2023). EDP Foz-Tua: Phytobenthos – Ecological Monitoring Program – Exploration Phase [2018-2020]. Version 1.1. EDP. Sampling event dataset https://doi.org/10.15468/8bwk66 accessed via GBIF.org on 2024-12-14.

Description

The dataset contains records of Phytobenthos (Diatoms) collected in the watershed of River Tua, and included in the Ecological Monitoring Program of the Environmental Impact Assessment of the Foz Tua Hydroelectric Dam, promoted by EDP – Energias de Portugal, S.A. Data were collected in the springs of 2018-2020 during field visits to two sampling points, upstream the reservoir, in rivers Tua and Tinhela. The first phase of the Ecological Monitoring Program (2018-2020) aims to evaluate the impacts of dam exploration in the water quality of the river. The occurrence of the target taxa was documented through 4777 records of species presence and number of individuals (valve counts).

Purpose

This dataset is part of a broader initiative whereby the company EDP - Energias de Portugal S.A. will made available biodiversity data collected during impact assessment and biological monitoring studies.

Sampling Description

Study Extent

The data were collected in the lower Tua valley (Northeast Portugal), up to 30 km from the mouth, in the municipalities of Alijó, Murça and Mirandela.

Sampling

Ephilitic 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).

Quality Control

All taxa were identified by experienced researchers
