Trophic positioning of meiofauna revealed by stable isotopes and food web analyses.
Despite important advances in the ecology of river food webs, the strength and nature of the connection between the meio- and macrofaunal components of the web are still debated. Some unresolved issues are the effects of the inclusion of meiofaunal links and their temporal variations on the overall river food web properties, and the significance of autochthonous and allochthonous material for t...

Settling blooms of filamentous cyanobacteria as food for meiofauna assemblages
Summer blooms of filamentous nitrogen-fixing cyanobacteria in the Baltic Sea are normally dominated by Aphanizomenon sp. and the toxin-producing Nodularia spumigena. In a 2-week laboratory experiment, we followed the uptake by representative benthic meiofauna species of 14C-labeled organic carbon from blooms, each dominated by one of these cyanobacteria. Natural bloom material was collected and...
متن کاملIntegrating Ecosystem Engineering and Food Web Ecology: Testing the Effect of Biogenic Reefs on the Food Web of a Soft-Bottom Intertidal Area
The potential of ecosystem engineers to modify the structure and dynamics of food webs has recently been hypothesised from a conceptual point of view. Empirical data on the integration of ecosystem engineers and food webs is however largely lacking. This paper investigates the hypothesised link based on a field sampling approach of intertidal biogenic aggregations created by the ecosystem engin...
متن کاملQuantitative importance and trophic role of heterotrophic dinoflagellates in a coastal pelagial food web
The quantitative importance and trophic role of heterotrophic dinoflagellates was s tuded at a permanent station in the Kattegat, Denmark. Heterotrophlc dinoflagellates were most abundant during periods characterized by large phytoplankton forms (e.g. diatoms and dinoflagellates). During these periods the heterotrophic dinoflagellate blomass corresponded to between 13 and 77 % of the phytoplank...
