The Ecology and Evolution of Deep-Sea Copepods: Niche Separation in a Three-Dimensional Habitat
Specialisation and niche separation are key processes for minimising or avoiding competition between co-occurring species. This study aimed at elucidating these processes for co-occurring meso- and bathypelagic representatives of two copepod families (Euchaetidae and Aetideidae) from the Arctic Fram...
