Preferred use of bacteria over phytoplankton by deep-sea nematodes in polar regions Universiteit Gent
The present study explored the selective feeding properties of Antarctic and Arctic deep-sea nematodes within an experimental setup. Nematodes are assumed to play an important role in the carbon flux within the polar bathyal food webs, but knowledge about their natural diets is limited. For the first time, deep-sea multicore sediment samples from both polar regions were incubated aboard research vessels with either 13C-labelled bacteria or ...
