CeDAMar–MarBEF Workshop on taxonomy and identification of deep-sea nematodes and the use of the NeMys tool kits

Location: Marine Biology section, University Ghent (Belgium)
Event Type: Workshop
Event Date: 2007-01-08    
End Date: 2007-01-12

Event Description:
Workshop on taxonomy and identification of deep-sea nematodes and the use of the NeMys tool kits
Marine Biology section University Ghent / Ann Vanreusel and collaborators
8 – 12 January 2007 / A CeDAMar –MarBEF training course

Application is open now – closed the 1st of November 2006

The most abundant metazoan group in deep-sea sediments are the free-living nematodes. In general, their relative importance in the benthos and their diversity increases with water depth from the continental shelf to the bathyal regions. However, this high bathyal biodiversity is not yet well understood especially when local diversity estimates are extrapolated to regional or even global scales. It is mainly the lack of taxonomic data that prevent unravelling the deep-sea nematode diversity at different scales. Local diversity data are present from several study areas in the deep sea illustrating that more than 50 genera and about 100 species can be found in a single sample of 10 ml. While high local diversity of deep-sea nematodes is partly explained by genera richness including many single observations of rare genera, the remaining part is due to high degree of speciation within the few dominant genera like Thalassomonhystera, Acantholaimus, but also other less abundant genera as Halalaimus, Molgolaimus and Microlaimus are known to be represented by several species within a single sample. Very few deep-sea nematode species have been taxonomically described so far which makes it very hard to get an idea of species distribution patterns in the deep-sea. Therefore we identified the need for a training course on the identification of dominant nematode genera, and the techniques required for taxonomic species descriptions
In addition we will make use of the NeMys database system which is developed to store as many as possible types of biological information on mainly marine taxa in a fully digital way. The concept of storing data on morphology, biogeography, taxonomy, literature, pictures, collections and molecular analyses in one dataset, creates a large group of possible end users and makes it possible to analyse and compare data on a taxonomic group from different points of view. The database was developed at the Marine Biology Section (Ghent University) mainly with focus on marine Nematoda.

Our workshop aims to provide the following expertise:
- To learn techniques for preparation of slides for taxonomic study (eg Cobb slides)
- To identify the major deep-sea genera
- To use Nemys as identification and archiving tool
- To make taxonomic descriptions for identification of within genera diversity
