Sediment trap samples reveal regional differences in the population structure of Calanus hyperboreus from the Arctic Ocean
Abstract Calanus hyperboreus is one of the dominant copepod species in the Arctic zooplankton communities. The impact of climate change varies among regions within the Arctic, implying that C. hyperboreus populations may be differently affected at different locations, but knowledge on seasonal popul...

Abstract Calanus hyperboreus is one of the dominant copepod species in the Arctic zooplankton communities.
