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 49 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 and specimens were collected along the valley of the River Tua (Northeast Portugal), from the river mouth to about 67 km upstream in the river Tuela and about 68 km upstream in the river Rabaçal, as well as in a Tua tributary (to about 27 km upstream in the Tinhela river), encompassing sampling areas in Trás-os-Montes e Alto Douro Region (sampling points in the municipalities of Alijó, Murça, Carrazeda de Ansiães, Vila Flor and Mirandela).

Couverture taxonomique

The taxonomic coverage of this dataset spans 1 phylum, 4 classes, 12 orders, 33 famillies, 68 genus and 161 species or infra-specific categories.

Couverture temporelle

Données sur le projet

he dataset contains records of the Lichen Flora (Fungi) collected in the scope of the Complementary Studies (2011) and the Ecological Monitoring Program (2012-2015) of the Environmental Impact Assessment of the Foz Tua Hydroelectric Dam, promoted by EDP – Energias de Portugal, S.A. Data were collected in the spring and autumn of 2011-2015, during field visits to a total of 49 sampling points distributed along the valley of the River Tua (Northeast Portugal), from the river mouth to about 67 km upstream in the river Tuela and about 68 km upstream in the river Rabaçal, as well as some in the Tua tributary, river Tinhela (to about 27 km upstream). The occurrence of the target taxa was documented through 610 records of field occurrences from 164 different taxa (including species, subspecies and organisms classified within species groups and at the genus level), harboured at PO Herbarium collection at Natural History and Science Museum of the University of Porto (MHNC-UP).

Méthodes d'échantillonnage

Sampling was designed not only to obtain data for Complementary Studies [2011] but also for the Ecological Monitoring Program (2012-2015) which included two general objectives: (1) Evaluation of the direct and indirect impacts of the dam construction on the lichen flora and (2) Evaluation of the effect of the implementation of minimization and compensation measures within the scope of the Tua dam construction on the lichen flora. Depending on the objectives defined for each of the 52 sampling points, one or more techniques of sampling were applied at each location: a) A prospective area of ​​approximately 2,500 m2 (25 m in all perpendicular directions from the sampling area centroid), whenever possible and in the absence of natural barriers, to (1) explore all lichen habitats and obtain the total inventory of Tua’s watershed lichen diversity (fieldwork for the Complementary Studies), and (2) to assess the importance of micro-reserves for the conservation of priority conservation taxa and lichen target communities; b) Three permanent squares with 50cm2 were located on homogeneous rock vertical surfaces at each sampling point to assess the indirect impact of the presence of the dam reservoir on the composition of mesophytic, xerophytic and hyper-xerophytic saxicolous lichen habitats; c) Ten 50 cm bands (measured from the base of the trunk) covering the entire perimeter of the trunk on ten selected trees at each sampling point to evaluate the effect of measures for the recovery and planting of native riparian vegetation on lichen epiphytic flora. The parameters taken in each sampling procedure included (1) list of taxa, (2) list of priority conservation taxa, (3) percentage cover for each species, and (4) frequency of occurrence of each taxon in each lichen community. However, in this dataset, all taxa are presented in the presence/absence format only. Whenever possible, all specimens were identified in the field. Sterile or untypical specimens were identified at the laboratory using microscopic diagnosis. Lichen specimens were classified down to the lowest possible rank.
