Retrospect on Meiobenthology and Outlook on New Approaches and Future Research
Nineteenth century until the end of the 1950s. Taxonomic and faunistic papers; microscope studies; establishment of the special character of many meiobenthic animals; attempts to define meiobenthos “coenoses” (stable communities) based on sediment structure.
1960 into the 1970s. Descriptive ecology of the meiobenthic habitat (abundance, distribution); analysis of abiotic factors (restricted to the technically more simple parameters) and their distributional impacts; first experimental work on meiobenthic animals.
1970s to the beginning of the 1980s. Experimental work, tolerance-preference tests; first studies on “difficult” abiotic parameters like the oxygen/sulfide complex and its impact on the distribution; biotic and trophic factors (predator-prey interactions); ultrastructure studies with respect to phylogenetic implications.
1980s into the 1990s. Manipulative ecology as an aid to understanding the role of meiofauna in benthic ecosystems; calculations of production and energy flow; meiofauna in special biotopes like the deep-sea and sulfidic environments; recolonization and dispersive mechanisms of meiofauna, impact of pollution on meiofauna; life history assays.
End of 1990s to 2010(?). Three major domains appear dominant.
Biodiversity, its assessment and conservation: characterizing “hot spots” of meiofauna biodiversity; work on diversity-relevant factors (habitat complexity); impact of natural and anthropogenic disturbance on diversity.
Incorporating the potential of computerization: compilation of computer-assisted databases and networks on meiofauna; development of electronic identification keys.
Molecular genetics: phylogenetic relations and evolution of taxa; distributional patterns and their genetic background; coherence of remote populations; genetic changes under extreme conditions; genetic alterations induced by pollutants (ecotoxicogenomics); tracing trophic pathways. These are just a few aspects that the powerful tool of molecular genetics is already contributing to meiobenthology. Will they become the main research areas in this century?
