Whole-body nutrient composition of calcium, potassium, and sodium is documented for 37 species of forest floor arthropods. Sodium concentrations averaging 4.6 mg Na/g ash-free dry weight, and potassium concentrations averaging 6.2 mg K/g ash-free dry weight were relatively consistent within and among major taxonomic categories. Calcium content varied from 0.3 to 509.8 mg Ca/g ash-free dry weight, with highest values associated with Diplopoda and related species possessing highly calcified exoskeletons. Within-species variation in chemical composition often exceeded seasonal fluctuations, although several species exhibited significant temporal changes in whole-body nutrient composition of calcium, potassium, and sodium. 9 references, 3 tables.
