Response of benthic meiofauna to nutrient enrichment of experimental marine ecosystems

Chemical Interactions in Antarctic Marine Benthic Ecosystems

Differential response of benthic meiofauna to anoxia with special reference to Foraminifera (Protista: Sarcodina)

Sediments collected from the northwestern Adriatic Sea (Mediterranean) w ere exposed to anoxic bottom-water conditions for more than 2 mo in order to examine the resistance of dominant meiobenthic taxa to prolonged anoxia. Copepods appeared to be most sensitive to anoxia, with densi­ ties being reduced to zero within l i d . Compared to oxic conditions, densities of both nem atodes and soft-she...

Differential Response of High-Elevation Planktonic Bacterial Community Structure and Metabolism to Experimental Nutrient Enrichment

Nutrient enrichment of high-elevation freshwater ecosystems by atmospheric deposition is increasing worldwide, and bacteria are a key conduit for the metabolism of organic matter in these oligotrophic environments. We conducted two distinct in situ microcosm experiments in a high-elevation lake (Emerald Lake, Sierra Nevada, California, USA) to evaluate responses in bacterioplankton growth, carb...
