Annual cycle of lipid content and lipid class composition in zooplankton from the Beaufort Sea shelf, Canadian Arctic
We determined seasonal cycles of lipid content, lipid class composition, and carbon and nitrogen content of seven taxa of zooplankton that were collected from the Beaufort Sea shelf, Canadian Arctic, over a 10-month period (September 2003 – August 2004). All taxa except the chaetognath Parasagitta e...
