Seasonal and individual variability of lipid reserves in Oithona similis (Cyclopoida) in an Arctic fjord
International audience The lipid storage of the cyclopoid copepod Oithona similis was investigated from spring to late summer 2007 in Kongsfjorden (Svalbard, Norway). The volume of lipid droplets in each individual reflected the amount of stored wax esters. Seasonal changes of lipid storage coupled...
