Benthic Marine Habitats in Antarctica

Benthic habitats in Antarctica differ from those in other parts of the world in several important characterislies. Most of the Southern Ocean overlies the abyssal plain, where the sediments are primarily siliceous. Icc-rafted debris provides isolated patches of hard substratum but otherwise little is known of the biology of the deep-sea in Antarctica. Shallow WOller habitats are heavily influen...

Denitrification and Biodiversity of Denitrifiers in a High-Mountain Mediterranean Lake

Wet deposition of reactive nitrogen (Nr) species is considered a main factor contributing to N inputs, of which nitrate ([Formula: see text]) is usually the major component in high-mountain lakes. The microbial group of denitrifiers are largely responsible for reduction of nitrate to molecular dinitrogen (N2) in terrestrial and aquatic ecosystems, but the role of denitrification in removal of c...

Biotic interactions in freshwater benthic habitats

We summarized studies on the impacts and scale effects of negative (competition, predation, parasitism, herbivory) and positive (mutualism, commensalism, indirect facilitation) species interactions in freshwater benthic habitats since ,1986 and focused on organisms with mainly or entirely aquatic life cycles. Benthologists publishing in J-NABS have contributed robustly to our overall knowledge ...

Biotic and abiotic controls on co-occurring nitrogen cycling processes in shallow Arctic shelf sediments

The processes that convert bioavailable inorganic nitrogen to inert nitrogen gas are prominent in continental shelf sediments and represent a critical global sink, yet little is known of these pathways in the Arctic where 18% of the world's continental shelves are located. Moreover, few data from the Arctic exist that separate loss processes like denitrification and anaerobic ammonium oxidation...
