Role of lipid in the life cycles of ice-dependent and ice-independent populations of the copepod Paralabidocera antarctica

We compared the lipid stores of coastal and lacustrine populations of the copepod Par- alabidocera antarctica over a complete developmental cycle. The life cycle of the coastal population, which was reflected in their pattern of lipid storage, was coupled closely to the growth of sea ice. Nauplii entered the sea ice in early autumn and overwintered predominantly as the NIV stage, with triacylglycerol comprising up to 26% of their dry weight (DW). During their rapid development from stages CI to CIV, much smaller quantities (
