ISSN 1377-0950 ii PREFACE The meiobenthologists’ international meetings began officially in Tunisia, in 1969, when 28 researchers gathered to discuss the taxonomy and ecology of meiobenthos. A second meeting followed four years later in York (UK), in 1973, and a third one occurred in Hamburg (Germany) in 1977. From then onwards, the tri-annual International Meiofauna Conference was born. Every three years, more participants join the group, and there seems to be an ever increasing wealth of knowledge being shared at these events. So far, 13 IMCo's have taken place. Ghent University, its Marine Biology Research Group and the International Association of Meiobenthologists, are proud to have welcomed all meiofauna students, scientists and enthusiasts to FourtIMCo, the 14th International Meiofauna Conference, in Ghent, 11-16 July 2010. FourtIMCo provides a multidisciplinary forum to researchers from disciplines such as community and population ecology, taxonomy, phylogeny and phylogeography, environmental studies, biogeochemistry and microbiology, that study habitats from freshwater over estuarine to marine environments. The meiofauna is the overarching theme connecting these very different lines of research and habitats with studies also involving meiofauna as one component of larger and more encompassing research themes, such as benthic carbon flows, foodweb models, biodiversity studies, environmental impact and management among others. During the FourtIMCo conference, 73 abstracts were given in oral presentations, and 128 abstracts as poster presentations, by 180 scientists from 28 countries. The FourtIMCo programme hosts sessions on the following themes: . Biodiversity and biogeography of meiofauna (27 oral and 50 poster) . Taxonomy and phylogeny of meiofauna (11 oral and 36 poster) . Meiofauna research as a basis for environmental management (11 oral and 11 poster) . Freshwater meiofauna (7 oral and 6 poster) . Ecological interactions and energy flow (14 oral and 8 poster) . Meiofauna in pollution studies (6 oral and 12 poster) M. Vincx P.
