Kleinskalige Heterogenität in der arktischen Tiefsee: Einfluß kleiner Kaltwasser-Schwämme auf die Diversität benthischer Nematoden-Gemeinschaften
In connexion with the high species richness of deep-sea sediments the question arises which spatial processes influence the species composition, abundance and biomass of the communities. Which processes produce and maintain diversity in the deep sea and at what spatial scales do they operate?The bac...
