The dataset includes 3305 georeferenced points/records. The data records were gathered using three types: digitatalization, exact occurences and expert judgement. The georeferenced data was extracted from the scientific publications and specialized databases (AquaNIS, ICES and Google scholar).

During the last 40 years of survey in the Lebanese seawaters and the Levantine Basin, we identified and described about 400 species, belonging to 85 genera, including 230 dinoflagellates and 156 diatoms, 10 Silicoflagellates and 4 Ebriidae, many of them are introduced or migrated from Red Sea and Indian Ocean into the Mediterranean, through the Suez Canal pathway.

Polychaete fauna were sampled from bottom sediment during three seasons between autumn 2006 and spring 2007. Samples were taken during low tide from 7 stations at the eastern harbour of Alexandria (Egypt) at depths between 3 and 11 meters. 12 Polychaete species were encountered of which 3 are considered new in the Egyptian Mediterranean waters. The collected specimens were preserved at Marine Reference Collection Center of National Institute of Oceanography and Fisheries, Alexandria, Egypt.

The present publication provides a data set from five camera-trapping sampling campaigns on two islands of the Azorean archipelago (Pico and Terceira islands). Between 2013 and 2018, two sampling campaigns were conducted on Terceira island ("TER_13-15" survey) and on Terceira and Pico islands ("TER-PIC_18" survey) aimed to study the ecology of introduced mammals. A third sampling campaign was performed between 2015 and 2017 sampling was performed in vineyards on Terceira island in order to evaluate grape consumption by vertebrates species ("Vineyards_15-17" survey). Additionally, between 2016 and 2018, two sampling campaigns were performed in Terceira island, in order to assess the impact of introduced mammals on native birds, on Cory's Shearwater (Calonectris diomedea borealis; "Calonectris_16" survey) and the Azores woodpigeon (Columba palumba azorica; "Columba_17-18" survey), through nest predation monitoring. A total of 258 sites and 47 nests were sampled using camera traps. These sampling campaigns provided a large data series that allowed create a vertebrate wildlife inventory of Azores

The data in this dataset results from different sampling campaigns along the Mediterranean coast of Egypt and the Suez Channel. Most samples of Polychaetes were taken using a Van Veen grab, while samples from Port Said Harbour were collected by knife and net used for collecting fauna. Specimens including those of newly described species were deposited at the Marine Reference Collection Center of National Institute of Oceanography and Fisheries, Alexandria under Code Numbers.

Within the frame work, organized by the National Institute of Oceanography and Fisheries, Alexandria, Egypt, 15 quantitative samples were collected and analysed for Polychaetes using a Van Veen grab on the soft bottom, at depths ranging from 12m to 106 m. Samples were taken over two seasons (spring and summer, 2008) during two trips to the Northeastern coast of the Egyptian Mediterranean waters at El Tina Bay, Balteem, Abokhashaba and Gamasa.

This dataset contains comprehensive information about the global alien spread and distribution of macrofungi species during the last centuries (1753-2018)

This dataset contains data of zooplakton species which were found in Lebanese waters. The study area extends over 150 km between the south of Lebanon and offshore Tripoli city in the North. Monthly, seasonally and annual cruises were carried out between 1965 and 2007. Surface and vertical plankton samples were taken at standard depths 0m, 0-25m, 0-100m, 0-200m. Data are available as a classification of the frequency of occurance.
