The early marine meiofaunal... particularly at the surface, harpacticoid copepods Cullen (1973) experimentally demonstrated the bioturbative impact of meiofauna He found that their burrowing activities alone eliminated all surface traces of macrofauna within 14 days In average sandy sediment, the burrowing of meiofauna will completely displace the pore water in 1–3 years (Reichelt 1991) Because of meiofaunal bioturbation the transport of solutes... effects of bioturbation in Baltic Sea sediments compared to those of physical processes On a general scale, the chemical impacts of the biogenic mobilization of buried chemical pollutants on meiofauna have not yet been sufficiently evaluated While macrofaunal burrows affect the sediment, even the dense net of mmfine burrows of meiofauna can have a considerable influence on sediment structure and fauna. .. multidirectional meiofaunal research may include the inconspicuous nature of meiobenthic organisms and their unspectacular habitats This may have confounded the real phylogenetic and ecological roles of meiofauna Today, the International Meiofauna Association and its triennial conferences bring together work in all fields of meiofauna research and most scientists that are studying meiobenthos Chapter 2 The Biotope:... even stated that the microscopic fauna were so rich “that it would take years to study them.” However, these pioneers of meiofauna considered only isolated taxa—often the exceptional species of known invertebrate groups—not their ecological niches and community aspects 1.2 A History of Meiobenthology 3 Since then, field investigations were biased towards commercially interesting macrofauna Consequently,... series of investigations (beginning in 1942) on the fauna of the groundwater He found the “stygobios” to be a distinct faunal element (see Sect 8.2.1) The “hyporheic” biotopes beneath streams and rivers were the research domain of Karaman (1935), Orghidan (1955) and collaborators They were attracted by the interesting subterranean fauna of karstic rivers in 1.2 A History of Meiobenthology 5 Southeast... 1.1 Meiofauna, Meiobenthos: Definitions The term “meiofauna” denotes microscopically small, motile aquatic animals living mostly in and on soft substrates at all depths in the marine and freshwater realm Although originally restricted to small metazoans, ecological connections suggest that larger protozoans (ciliates, amoebozoans) should also be included in the scope of meiofauna In the context of this . h0" alt="" Meiobenthology The Microscopic Motile Fauna of Aquatic Sediments Olav Giere Meiobenthology The Microscopic Motile Fauna of Aquatic Sediments 2 nd . meiofauna of sands (Remane 1933, see Sect. 1.2).
