Zooplankton in Changing Arctic Seas: Examples from West Greenland Ecosystems
With reduced sea ice cover, increased melt water discharge and pelagic primary production the transfer to higher trophic levels through zooplankton will change; e.g. species composition, phenology and productivity of the zooplankton community may be altered. In this presentation, we use dataset from...
