Географический охват

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 municipality of Alijó, Murça, Carrazeda de Ansiães, Vila Flor and Mirandela). Two additional areas were surveyed in rivers Pinhão and Corgo rivers, located in Sabrosa and Régua municipalities, respectively (Douro river sub-basin).

Таксономический охват

The taxonomic coverage of this dataset spans 1 phylum, 5 classes, 19 orders, 49 famillies, 98 genus and 170 species or infra-specific categories.

Данные проекта

The dataset contains records of the Bryophyte Flora (Bryophyta) 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). There were also surveys in rivers Pinhão and Corgo (river Douro sub-basin), and one sampling point was established in each river, in 2015. The occurrence of the target taxa was documented through 1147 records of field occurrences from 170 different taxa (including species, subspecies, varietas and organisms classified at the genus level), harboured at PO Herbarium collection at Natural History and Science Museum of the University of Porto (MHNC-UP)). The most common taxa (> 20 records) were Hypnum cupressiforme Hedw. (28), Grimmia decipiens (Schultz) Lindb. (27), Scorpiurium deflexifolium (Solms) M.Fleisch. & Loeske (25), Nogopterium gracile (Hedw.) Crosby & W.R.Buck (24), Scleropodium touretii (Brid.) L.F.Koch (24), Campylopus pilifer Brid. (23), Lunularia cruciata (L.) Lindb. (22), Scapania compacta (A.Roth) Dumort. (21) and Gongylanthus ericetorum (Raddi) Nees (21). Priority conservation taxa found at the studied locations include taxa such as Anacolia webbii (Mont.) Schimp., Antitrichia californica Sull., Barbilophozia barbata (Schmidel ex Schreb.) Loeske, Bryum minii Podp. ex Machado-Guim., Cinclidotus riparius (Host ex Brid.) Arn., Coscinodon cribrosus (Hedw.) Spruce, Dendrocryphaea lamyana (Mont.) P. Rao., Marsupella sprucei (Limpr.) Bernet, Orthotrichum rivulare Turner, Plagiochila porelloides Torrey ex Nees) Lindenb., Racomitrium hespericum Sérgio, J. Muñoz & Ochyra, Schistidium rivulare (Brid.) Podp., Schizymenium pontevedrensis (Luisier) Sérgio, Casas, Cros & Brugués and Triquetrella arapilensis Luisier.

Методы сбора

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 bryophytic 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 bryophytic flora. Depending on the objectives defined for each of the 54 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 bryophyte habitats and obtain the total inventory of Tua’s watershed bryophyte diversity (fieldwork for the Complementary Studies), and (2) to assess the importance of micro-reserves for the conservation of priority conservation taxa and bryophyte target communities; b) Three permanent squares with 50 cm2 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 bryophytic habitats; c) Twenty sampling units of size 20 cm2, along 100 meters of the river segment at each sampling point (reference, impact and control), to evaluate the capacity of the reorganization of bryophyte communities in immersed and semi-immersed freshwater habitats subjected to the alteration of the hydrological regime upstream of the dam; d) 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 bryophyte epiphytic flora. Parameters taken in each sampling procedure include (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 bryophyte community. However, in this dataset, data are presented as presence/absence per sampling plot only.
