use of body measurements and serum metabolites to estimate the nutritional status of mallards wintering in the mississippi alluvial valley, usa.we collected mallards (anas platyrhynchos) from bottomland hardwood habitats on the bayou meto wildlife management area and the white river national wildlife refuge, arkansas county, arkansas during the winter of 1990 to 1991 to determine if measures of physiological condition could be predicted from structural size, serum metabolite levels, or from direct measures of carcass composition. serum triglyceride levels were correlated (r = 0.57, p = 0.007) with total body fat in males and slightly in ...19979027691
