The dataset contains the results of Iberian Wolf (Canis lupus) (Mammalia) surveys made in the lower valley of River Sabor (NE Portugal), some of its small tributaries, and in the rivers Maçãs and Angueira, 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. Surveys were made in the area affected by the dam, and in control areas farther from the dam, from June 2010 to August 2014. Sampling was performed 1-3 times a year, between May and November, with a total of 19-28 howling stations sampled each year. 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.

Data collected on the species composition, abundance and biomass, environmental parameters (T&S, dissolved oxygen and nutrients as well as bottom sediments composition and its structural compounds) regarding spatial and temporal localization.

This dataset includes systematic bird counts data collected from the “Regional Protected Landscape of the Vila do Conde Shoreline and the Mindelo Ornithological Reserve (PPRLVCROM – “Paisagem Protegida Regional do Litoral de Vila do Conde e Reserva Ornitológica de Mindelo”), a protected area in Northern Portugal. Data were collected in winter of 2013-2014 and spring 2014, in 18 observation points (10-minute recording time per point), in which all birds detected by sight and/or sound were recorded. A total of 612 records were made (average of 3.1 individuals per record), collected from 116 sampling events. Fifty-three species of 27 families were recorded.

Data on environmental factors, physical properties and live biomass of <i>Crassostrea cucullata</i> species sampled in a mangrove swamp in Gazi (May 1991). The data were digitized by VLIZ from the original report: Joseck, D. M. (1991). Aspects of ecomorphology of the mangrove oyster, Crassostrea cucullata, BORN (Bivalvia). BSc Thesis. University of Nairobi/KBP Kenya: Nairobi. 55 pp.

Species and abundance records by fishermen, on annual basis, for the period 1999-2011. Responsible for these records is the Department of Fisheries and in particular the Regional Agency of Arta.

Phytoplankton monitoring in the South Adriatic (Adricosm-STAR project), 2008-2009. Discrete water samples are taken at multiple depth layers. The samples were fixed with Ca(HCO3)2-buffered formaldehyde (0.8% final concentration) and cell abundance and species composition of phytoplankton were estimated according to Utermöhl’s method (1958), using an inverted microscope equipped with phase contrast, at 200-320-400x final magnifications.

The data were collected by the IBSS staff at several stations in the Black Sea during Cruise 5 in February 1957. This dataset contains abundance data (individuals per m³) and biomass data (mg/m³) for zooplankton taxa. No additional metadata is available.

Dataset contains species name, their number of specimen and wet-weight for each taxa (0,1 mg). Samples were originally preserved in formaline and later converted to ethanol. After identification samples are stored at Bergen Museum/University of Bergen.

Microzooplankton data collected within the ALPEADRIA monitoring project in the Gulf of Trieste, North Adriatic Sea in 1993.

Digitized Herbarium from the University of Malaga.
