A detailed distribution of true crabs (Brachyura) in the North-East Atlantic.

The dataset contains records of a key prey species of Bonelli’s Eagle (Aquila fasciata) and other large birds of prey, the Rabbit (Oryctolagus cuniculus) (Mammalia, Lagomorpha), 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 line transects 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 presence signs (scats, latrines) recorded per transect surveyed.

The data were collected by the IBSS staff at one diurnal station in Sevastopol Bay (Black Sea) during 1952. This dataset contains abundance data (individuals per liter) for phytoplankton taxa. No additional metadata is available.

Species frequencies, density and biomass for macrobenthos sampled in the Southern Bight of the North Sea between May 1971 and September 1972 and sediment grain size data for all 60 sampling locations. Samples were taken using Van Veen grabs. The data were digitized by VLIZ from the original report: Govaere, J. (1978). Numerieke analyse van het makrobenthos in de Southern Bight (Noordzee). PhD Thesis. Rijksuniversiteit Gent: Gent. 220, 122 tab. [2 delen] pp.

Densities of the most important meiobenthos phyla in an <i>Avicennia marina</i> mangrove sediment in Gazi Bay (Kenya) together with the sediment environmental data. Three replicate samples were taken for every monthly sample between August 1992 and July 1993. The data were digitized by VLIZ from the original report: Okondo, J. (1995). Community structure and seasonal fluctuation of meiobenthos in the Avicenna marina mangrove sediments at Gazi Bay, Kenya. MSc Thesis. RUG: Gent. 56 pp.

Delfini Metropolitani is a long term research project of Acquario di Genova to study the ecology of cetaceans and, in particular, of bottlenose dolphins (<i>Tursiops truncatus</i>).
