Sr/Ca ratios are given for 22 species of aquatic plants from Perch Lake, Ontario. When compared with the lake water, 16 species are found to discriminate against calcium relative to strontium. Consequently, these species introduce a strontium enrichment step into any food chain in which they participate. One species (Nymphaea odorata) however, shows a remarkable discrimination against strontium.
