Monthly abundance of dominant phytoplankton species at 2 permanent phreatic lagoons representing in Doñana.

The dataset contains records of bats (Chiroptera) collected in the lower valley of River Sabor, which were collected in the scope of the long-term Ecological Monitoring Program (PME) of the Baixo Sabor Hydroelectric Dams, promoted by EDP – Energias de Portugal, S.A. Data were collected between August 2008 and November 2014, during field visits to 97 known or presumed bat hibernation, reproduction and pre-dispersion (post-reproduction) roosts, within a 5-km radius buffer around the lower valley of River Sabor. 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 several “species complexes”, including either one or multiple genus. 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 the main avian prey species of Bonelli’s Eagle (Aquila fasciata) and other large birds of prey: Red-legged Partridge (Alectoris rufa), Rock Pigeon (Columba livia) and Wood Pigeon (Columba palumbus) (Aves, Galliformes and Columbiformes), 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 point counts performed each season (winter, spring, summer and autumn), in the known territories of the Bonelli's Eagle in the lower Sabor river valley, from February 2010 to September 2014. Data consists of observations of individuals per sampling point.

The dataset contains records of Iberian Wolf (Canis lupus), Wild Boar (Sus scrofa) and Roe Deer (Capreolus capreolus) 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 March 2011 to August 2014. Sampling was performed by camera-traps distributed along the lower Sabor river valley (and some tributaries) and in rivers Maçãs and Angueira, from the river mouth up to 42 km upstream. The presence and identity of the target species were assessed by observing the photos taken with the cameras. A total of 3879 photos of the target species were obtained (2892 of Sus scrofa, 982 of Capreolus capreolus, and 5 of Canis lupus). These numbers do not necessarily refer to different individuals.

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 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 dam, from November 2010 to December 2014. Sampling was performed in transects distributed along the lower Sabor river valley (and some tributaries), and along the rivers Maçãs and Angueira, up to 42 km upstream. The presence and identity of the target species were assessed through the presence of faeces (spraints) and/or footprints of the target species.

The dataset contains records of the Iberian Wolf (Canis lupus) 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 transects distributed in the area of the lower Sabor river valley (and some tributaries) and in rivers Maçãs and Angueira, from the river mouth up to 42 km upstream. The presence and identity of the target species were assessed through presence signs, mainly scats. However, since the scats attributed to the wolf were not validated with molecular tools to screen for possible confusion with those of domestic dogs, their taxonomic identification in this dataset is presented at the genus level.

The dataset contains records of the Roe Deer (Capreolus capreolus), a major wild prey of the Iberian Wolf, 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 June 2010 to April 2014. Sampling was performed in transects distributed along the lower Sabor river valley (and some tributaries), and in rivers Maçãs and Angueira, from the river mouth up to 42 km upstream. The presence of the target species was assessed through faecal pellet surveys, due to difficulties in directly observing the species.

The dataset contains records of Iberian Wolf (Canis lupus) 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 spotlight counts made in and around the area affected by the dam, from June 2010 to September 2014. Sampling was performed at fixed transects (spotlight counts) distributed along the lower Sabor river valley and some of its small tributaries, and in the rivers Maçãs and Angueira, from the river mouth up to 42 km upstream. The presence and identity of the target species would be assessed by direct observation of individuals during spotlight counts. No detection of Iberian wolf was obtained during these surveys, thus the dataset reports on locations where the species was deemed absent, thereby providing a baseline to assess future changes in species occurrence patterns.
