The dataset contains records of Common Kingfisher (Alcedo atthis) and Dipper (Cinclus cinclus) (Aves) collected in the lower catchment 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. This dataset includes results of surveys made in and around the area affected by the dams, from August 2010 to September 2014. Sampling was performed in transects distributed along the lower Sabor river valley (and some tributaries) and in rivers Maçãs and Angueira, from the Sabor mouth up to 42 km upstream. The presence and identity of bird species were assessed by visual and/or acoustic observation, with binoculars. The records include taxa identified at the species level.

This dataset is the output of a national waterbird monitoring programme coordinated by ICNF that collects information on the number and distribution of waterbirds at wetland sites in Portugal and is part of the International Waterbird Census project (African-Eurasian Waterbird Census – Europe). The dataset consists of annual waterbird counts, undertaken from 2000 to 2013, of species regularly encountered at wetlands and observed in all types of natural and man-made wetlands in mainland Portugal. In this dataset there is a record of 84 waterbird species, 20 families and 11 orders (Accipitriformes, Anseriformes, Charadriiformes, Ciconiiformes, Gaviiformes, Gruiformes, Pelecaniformes, Phoenicopteriformes, Podicipediformes, Strigiformes, Suliformes).

The dataset contains records of the Otter (Lutra lutra) 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. This dataset includes results of surveys made in and around the area affected by the dams, from September 2010 to November 2013. Sampling was performed with camera-traps distributed along the lower Sabor river valley (and some tributaries) and along the rivers Maçãs and Angueira, from the river mouth up to 42 km upstream. The presence and identity of the target species were assessed with the visualization of photos taken through camera-trapping.

The dataset contains records of Butterflies (Lepidoptera) collected in the lower valley of the River Tua, and included in the Ecological Monitoring Program (2011-2017) of the Foz Tua Hydroelectric Dam, promoted by EDP – Energias de Portugal, S.A. Data were collected between July 2014 and August 2017 during field visits to 33 sampling transects with favorable habitats on the area of the lower Tua valley directly or indirectly affected by the Foz Tua dam, and in a small stream of the Douro basin. The occurrence of the target species was recorded when individuals were seen or captured in the selected transects.

The dataset contains records of terrestrial, aquatic and riparian birds (Aves) collected in the lower valley of River Sabor (NE Portugal), in the scope of the monitoring programs of the Baixo Sabor Hydroelectric Dams (AHBS), promoted by EDP – Energias de Portugal, S.A.. Specifically, the dataset relates to monitoring carried out to evaluate the effectiveness of measures implemented to mitigate the impacts of AHBS. In this case, the mitigation measures refer to "MC1 - Compensatory Habitat of Vilariça Stream". The dataset includes the results of bird surveys made in the Vilariça stream from January 2013 to September 2014. Sampling was performed in selected points distributed along the stream, up to 5 km upstream of the mouth. The presence and identity of bird species were assessed by visual and/or acoustic observations, with binoculars. The records include taxa identified at the species or genus levels.

The dataset contains records of the Eagle Owl (Bubo bubo) and other nocturnal birds of prey (Aves) 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. A total of 32 acoustic sampling points was established along the lower Sabor river valley and in its main tributaries, which were visited each year in the peak of the species' breeding season (February) from 2010 to 2014. Data contains a total of 19 observation events of Bubo bubo (17) and Strix aluco (4).

The dataset contains records of aquatic and riparian birds (Aves) 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. This dataset includes results of surveys made in and around the area affected by the dam, from February 2010 to September 2014. Sampling was performed in selected points distributed along the lower Sabor river valley, from the river mouth up to 42 km upstream. The presence and identity of birds were assessed by visual and/or acoustic observation with binoculars and/or telescope. The records include taxa identified at the species or genus levels.

The dataset contains records of bats (Chiroptera) collected in the lower valley of the River Tua and included in the Baseline (2008-2009) and Complementary (2010) Studies of the Environmental Impact Assessment of the Foz Tua Hydroelectric Dam, promoted by EDP – Energias de Portugal, S.A. Data were collected between November 2008 and April 2010 during field visits to 27 known or presumed bat roosts used for hibernation and/or reproduction, within a 15-km radius buffer around the Tua valley. The presence of individuals was recorded by direct observation. When the identification raised doubts, or the numbers were too high to allow individual examination, the specimens were photographed for later identification. The records include taxa identified at the species or genus level. In several occasions it was not possible to separate the potential species of the genus Myotis, so they were simply included in 2 “species complexes”: “large” Myotis (2 species) and “small” Myotis (5 species). Due to the vulnerability of the roost locations, the precision of the geographic coordinates was degraded to 0.01, according to the recommendations of Chapman & Grafton (2008). The dataset with the original (undegraded) coordinates may be provided upon request by the resource contact from EDP, who will define the terms and conditions for its use.

The dataset contains records of bats (Chiroptera) collected in the lower valley of River Tua. Data were collected in the scope of the long-term Ecological Monitoring Program (PME) and the Monitoring Program of Mitigation/Compensation Measures (PMC) of the Foz Tua Hydroelectric Dam, promoted by EDP – Energias de Portugal, S.A. Data were collected between July 2011 and September 2017 during field visits to 91 known or presumed bat hibernation, reproduction and pre-dispersion (post-reproduction) roosts, within a 5-km radius buffer around the lower valley of River Tua. From 2012, two roosts located at >20 km from the river (deactivated railroad tunnels) were added to the sampling sites in the context of the PMC. The presence of individuals was recorded by direct observation, and all individuals were photographed whenever possible. The records include taxa identified at the species or genus level. In several occasions it was not possible to separate the individual species, so they were grouped in 15 “species complexes”, both mono-specific and multi-specific. Due to the vulnerability of the roost locations, the precision of the geographic coordinates was degraded to 0.01, according to the recommendations of Chapman & Grafton (2008). The dataset with the original (undegraded) coordinates may be provided upon request by the resource contact from EDP, who will define the terms and conditions for its use.

A dataset of Polychaeta collected from 4 major ports of Greece: Pireaus, Patra, Heraklion, Rhodes during the period 2020-2021. For this purpose, a netted frame and a suction sampler were used to sample the benthic fauna on artificial reefs (of concrete) and floating platforms. This work is part of the project AlienPorts.
