Biotic interactions in freshwater benthic habitats

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 ...

Uncertain biotic and abiotic interactions in benthic communities

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...

Species-specific responses of two benthic invertebrates explain their distribution along environmental gradients in freshwater habitats.

The absence of species in polluted sediments does not necessarily imply exclusion due to toxicity. Other factors, like for instance food availability and oxygen content, could also partly cause their absence. Hence, knowledge of the (combinations of) factors acting on individual organisms is essential in order to understand how populations can persist in polluted sediments. In this study specie...
