Summary Marine nematode worms without a mouth or func- tional gut are found worldwide in intertidal sandflats, deep-sea muds and methane-rich pock marks, and morphological studies show that they are associated with endosymbiotic bacteria. While it ha

The role of ecological divergence in speciation between intertidal and subtidal Scoloplos armiger (Polychaeta, Orbiniidae)

Autor: Frank Thiermann, Matthias Strasser, Inken Kruse

Publikováno v: Journal of Sea Research. 51:53-62

The model of ecological speciation implies that habitat differences may split a species by strong selection and rapid adaptation even under sympatric conditions. Recent studies on the polychaete Scoloplos armiger in the Wadden Sea, North Sea, indicat

Leptonemella species (Desmodoridae, Stilbonematinae), benthic marine nematodes with ectosymbiotic bacteria, from littoral sand of the North Sea island of Sylt: taxonomy and ecological aspects

Autor: Lars Bock, Franz Riemann, Frank Thiermann

Publikováno v: Helgoland Marine Research. 57:118-131

Leptonemella species represent a dominant element of the nematode fauna in sulfidic, deep sediment layers on the sandy shore of Sylt. Based on collections sampled here in 1991–1999, a taxonomic treatise is presented on the three co-existing species

Endosymbiotic sulphate-reducing and sulphide-oxidizing bacteria in an oligochaete worm

Autor: Caroline Mülders, Rudolf Amann, Dirk de Beer, Annelie Pernthaler, Timothy G. Ferdelman, Jens Krieger, Michael Klein, Nicole Dubilier, Christer Erséus, Frank Thiermann, Michael Wagner, Olav Giere

Publikováno v: Nature. 411:298-302

Stable associations of more than one species of symbiont within a single host cell or tissue are assumed to be rare in metazoans because competition for space and resources between symbionts can be detrimental to the host1. In animals with multiple e

Variations in the sulfide regime and the distribution of macrofauna in an intertidal flat in the North Sea

Autor: O. Giere, A. S. Niemeyer, Frank Thiermann

Publikováno v: Helgoländer Meeresuntersuchungen. 50:87-104

Sulfide concentrations were measured in the inner and outer Konigshafen (Sylt, Wadden Sea) from November 1990 to December 1991 to assess the fluctuations of sulfide levels in natural tidal habitats. Three different areas were compared: (1) muddy sedi

Sulphide tolerance of the marine nematode Oncholaimus campylocercoides - a result of internal sulphur formation?

Autor: Bent Vismann, Olav Giere, Frank Thiermann

Publikováno v: University of Copenhagen

The free-living, marine nematode Oncholaimus campylocercoides occurs in high abundance (up to 600 ind. 10 cm -2 ) at the fringe area of shallow-water hydrothermal vents off the Greek island of Milos in the Aegean Sea. It was found to have a sulphide
