Diversity of calanoid copepods in the North Atlantic and adjacent seas: species associations and biogeography
International audience Present-day patterns in pelagic biodiversity are the result of the interaction of many factors acting at different scales, Developing an understanding of the processes that regulate the diversity of oceanic ecosystems is thus challenging. In this study, diversity of calanoid c...

International audience Present-day patterns in pelagic biodiversity are the result of the interaction of many factors acting at different scales, Developing an understanding of the processes that regulate the diversity of oceanic ecosystems is thus challenging.

For the first time, at an oceanic basin scale and with a spatial resolution approaching the mesoscale, species associations of calanoid copepods have been identified.
