A selected portion of the samples will be chosen for analysis of specific isotopes to add to the basic knowledge of trace mineral uptake by the forms in the island-lagoon environment. (b) Studies on the populations of rats on Janet Island to evaluate the soil-plant-rat-igotope relationship will be undertaken.
