✦ Synopsis

Changes in biochemical composition were determined for the isopod Mesidotea entomon (Linnaeus) from two differing ecological habitats in the western Arctic. Isopods from Pauline Cove, Yukon Territory, showed quantitative differences in total lipid and carbohydrate compared with those of similar body size from Dolomite Lake, Northwest Territories. Total chitin, ash, and protein were similar in isopods from both sites. A seasonal accumulation of protein and lipid was observed in isopods from Dolomite Lake prior to the onset of winter. The roles of ecological habitat, season, parasitism, nutritional and reproductive cycles in the organic composition of M. entomon are discussed.
