Paper: Molecular ecology

Ultrasequencing of the meiofaunal biosphere: practice, pitfalls and promises


Biodiversity assessment is the key to understanding the relationship between biodiversity and ecosystem functioning, but there is a well-acknowledged biodiversity identification gap related to eukaryotic meiofaunal organisms. Meiofaunal identification is confounded by the small size of taxa, morphological convergence and intraspecific variation. However, the most important restricting factor in meiofaunal ecological research is the mismatch between diversity and the number of taxonomists that are able to simultaneously identify and catalogue meiofaunal diversity. Accordingly, a molecular operational taxonomic unit (MOTU)-based approach has been advocated for en mass meiofaunal biodiversity assessment, but it has been restricted by the lack of throughput afforded by chain termination sequencing. Contemporary pyrosequencing offers a solution to this problem in the form of environmental metagenetic analyses, but this represents a novel field of biodiversity assessment. Here, we provide an overview of meiofaunal metagenetic analyses, ranging from sample preservation and DNA extraction to PCR, sequencing and the bioinformatic interrogation of multiple, independent samples using 454 Roche sequencing platforms. We report two examples of environmental metagenetic nuclear small subunit 18S (nSSU) analyses of marine and tropical rainforest habitats and provide critical appraisals of the level of putative recombinant DNA molecules (chimeras) in metagenetic data sets. Following stringent quality control measures, environmental metagenetic analyses achieve MOTU formation across the eukaryote domain of life at a fraction of the time and cost of traditional approaches. The effectiveness of Roche 454 sequencing brings substantial advantages to studies aiming to elucidate the molecular genetic richness of not only meiofaunal, but also all complex eukaryotic communities.

7th European Ostracodologists’ Meeting

7th European Ostracodologists’ Meeting!
EOM has been taken place for the first time at Frankfurt/Main in 1989. Now, it has become a very important and traditional convention in this field of science. Although it is called a “European Meeting”, usually people from all over the world join this conference and are highly welcomed.
EOM 7 is open for any contribution dealing with ostracods. Deep time or Recent ostracods, freshwater or marine mussel shrimps, pure taxonomy, (palaeo-)environmental, (palaeo-)biogeographical or biostratigraphical studies, genetical and morphometrical analyses or even new methodical approaches are greatly appreciated.
EOM 7 takes place in Graz, located in south-eastern Austria. Parts of this medieval city are not only a UNESCO World Heritage, but Graz is also well known as a city of universities (founded in 1585), famous museums (Joanneum, founded 1811) and modern arts (cultural capital of Europe in 2003). All together: a stimulating place for our – hopefully – successful meeting! If you are interested, please see the following fact sheets.

International Colloquium on Amphipoda
Sep. 13-18, 2010. 

The XIVth International Colloquium on Amphipoda will be held in the Faculty of Biology (green building) at Campus Reina Mercedes of the University of Sevilla, Spain, 13-18 September 2010

The International Association of Meiobenthologists is pleased to invite you to participate in its

14th International Meiofauna Conference
Ghent - Belgium
July 11-16, 2010

The conference will be hosted by Ghent University, in the province of Eastern Flanders. The city of Ghent is located at the cultural and economic heart of Europe. It is one of the leading institutions of higher education and research in the Low Countries. The Aula academica, situated in the beautiful historic city center, will be the conference venue.

The FourtIMCo aims to bring high-quality scientific presentations and discussions in a friendly, relaxed atmosphere, allowing optimal interaction between scientists from different levels, disciplines, etc… The organizers will therefore endeavour to provide a forum both to established experienced scientists and to young researchers in an early stage of their career.
