A world checklist of free-living marine Nematodes, compiled by taxonomic experts and based on peer-reviewed literature.

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.

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

Intertidal species effort based search undertaken by students (16+) and volunteer groups with support from an ecologist. During the twenty minute timed species search surveyors look for 22 species, 4 non native and 18 climate change indicator species within 1 of 3 habitats rockpools; boulders, crevices and overhangs or open rock. Abundance is recorded using a simplified version of SACFORN.

The main aim of the REDIT I campaign was to assess the geographical extend of the distribution of the polychaetous Serpulid Ditrupa arietina. Nevertheless, all macrofauna >1mm was identified.

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.

The nematode communities from 102 stations in the Southern Bight of the North Sea, sampled between 1972 and 1984, are examined. On the whole, 456 species, belonging to 159 genera and 37 families were found.

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.

The database contains abundance of main meiofaunal groups and of harpacticoid copepods separately. There are also data present from a recolonisation study.

The global objective of this project is to deliver a substantial contribution to the knowledge of the long term variability in the biodiversity of the macrobenthos and the relationship with anthropogenic activities on the Belgian Continental Shelf.
