Evolution of the Arctic Calanus complex: an Arctic marine avocado?
Before man hunted the large baleen whales to near extinction by the end of the nineteenth century, Arctic ecosystems were strongly influenced by these large predators. Their main prey were zooplankton, among which the calanoid copepod species of the genus Calanus, long considered key elements of polar marine ecosystems, are particularly abundant. These herbivorous zooplankters display a range o...
متن کاملIntraspecific Differences in Lipid Content of Calanoid Copepods across Fine-Scale Depth Ranges within the Photic Layer
Copepods are among the most abundant and diverse groups of mesozooplankton in the world's oceans. Each species has a certain depth range within which different individuals (of the same life stage and sex) are found. Lipids are accumulated in many calanoid copepods for energy storage and reproduction. Lipid content in some species increases with depth, however studies so far focused mostly on te...
متن کاملSea ice meiofauna distribution on local to pan‐Arctic scales
Arctic sea ice provides microhabitats for biota that inhabit the liquid-filled network of brine channels and the ice-water interface. We used meta-analysis of 23 published and unpublished datasets comprising 721 ice cores to synthesize the variability in composition and abundance of sea ice meiofauna at spatial scales ranging from within a single ice core to pan-Arctic and seasonal scales. Two-...
متن کاملVertical distribution of Calanus spp. and Metridia longa at four Arctic locations
We investigated the vertical distribution of Calanus finmarchicus, C. glacialis, C. hyperboreus and Metridia longa at four locations around the archipelago of Svalbard in autumn. The older and larger copepodites of Calanus spp. were generally located deeper in the water column. Differences in vertical distribution between stations partly reflected a south north gradient in developmental progres...
