Description: Das Projekt "The role of sympagic meiofauna for the flow of organic matter and energy in the Antarctic and Arctic sea-ice foodwebs" wird vom Umweltbundesamt gefördert und von Universität Kiel, Institut für Polarökologie durchgeführt. The brine channels in sea ice (Fig. 1) of both polar regions are the habitat of sympagic (ice-associated) bacteria, algae, protozoans and small metazoans greater than 20 mym (meiofauna, Fig. 2), including copepods, plathyelminthes, rotifers, nematodes, cnidarians, nudibranchs and ctenophores. Primary production of sympagic algae forms the basis of the sea-ice food web, which is coupled to the pelagic ecosystem and higher trophic levels. The overall objective of this project is to reveal the qualitative and quantitative role of sympagic meiofauna for the flow of organic matter and energy in the Antarctic and Arctic sea-ice foodwebs. The major focus is on sympagic meiofauna because this group could, due to in part very high abundances, play an important role within the sea-ice ecosystem. Moreover, since sympagic metazoans are a food source for higher trophic levels (e.g. larger zooplankton, fish), they probably occupy a key position in coupling processes between the sea ice and pelagic ecosystems. Sympagic meiofauna can thus be supposed to significantly contribute to the flow of organic matter and energy in polar marine food webs. In spite of this, little information on the feeding ecology of this group is available as yet.
