Inventory of Turbellaria species and examination of the share of Turbellaria in the meiofauna of the Zwin. The data were digitized by VLIZ from the original report: Revis, N. (1984). Studie van de Turbellaria in een slikke van het Zwin. BSc Thesis. Free University of Brussels: Faculty of Science: Brussel. A total of 29 samples were collected and divided over six sampling locations (Zwin1-Zwin6) between 14 September 1983 and 09 March 1984. The Turbellaria define 1 to 39% of the meiofauna. In total there were 47 species (without Acoela, except <i>P. rubra</i>) found in the Zwin, from which 43 were determined to species level. From those, there is one new for science: <i>Archilopsis arenaria.</i>
Density and biomass of meiofauna for 6 sandy beaches (Knokke, Mariakerke, Oostende, Heist, Bredene, Zwin) along the Belgian coast sampled between April 1985 and May 1986. The data were digitized by VLIZ from the original report: Jouk, P. (1992). Studie naar de ecologie van de vrijlevende Plathelminthes (Turbellaria) van de zandstranden van de Belgische kust. PhD Thesis. Limburgs Universitair Centrum: Diepenbeek. 2 volumes pp.
The Azores is a remote oceanic archipelago of nine islands which belongs to the Macaronesia biogeographical region and is among the richest regions concerning fungi, plant and animal diversity in Europe. This checklist lists all the species of the most important terrestrial and marine taxonomic groups. The total number of terrestrial and marine taxa (species and subspecies) in the Azores is estimated in about 8047. The marine organisms currently listed make up about 23% of the Azorean biodiversity. The total number of terrestrial and marine endemic taxa (species and subspecies) in the Azores is estimated of about 491.
This checklist includes, as rigorously as possible, all the known terrestrial and freshwater, i.e. insular, fungi, plants and animals of the Madeira and Selvagens archipelagos with the indication of their known presence on the islands of Madeira, Porto Santo, Desertas and Selvagens. It results from the collaborative work of many taxonomists from different Portuguese and foreign institutions (about 90 taxonomists), under the editorial coordination of the Azorean Biodiversity Group (http://www.gba.uac.pt). The total estimated number of terrestrial species and subspecies in the Madeira and Selvagens archipelagos was about 7,571 (7,452 species and 421 subspecies). Fungi and plants represent about 42% of the terrestrial diversity. However, animals dominate, arthropods being the majority (51%) of all recorded taxa. The total number of endemic species and subspecies from the Madeira and Selvagens archipelagos is about 1,419 (1,286 species and 182 subspecies), which represents 19% of the overall species diversity. The animal Phyla are the most diverse in endemic taxa, namely Mollusca (210) and Arthropoda (979), comprising about 84% of the Madeiran endemics. The percentage of endemism within Mollusca is particularly remarkable, reaching 71%. Within vascular plants there are 154 endemic species and subspecies (13% of the overall plant species diversity) while the remaining higher taxonomic groups are less diverse in terms of endemic forms: Fungi – 36 (5%); Lichens – 12 (2%); Bryophytes – 11 (2%); vertebrates 15 (24%).
