Figure 3: Global Distribution of Strontium Levels in Female Sperm Whales. This figure shows the global distribution of mean Sr levels in 193 adult female sperm whales grouped by sampling region. 1No female whales were found in the Chagos, Galapagos or Indian Ocean regions; 2Specific regions are named for the nearest land body or ocean region; 3All data are presented in ug total Sr/g tissue wet weight +/- standard deviation. Regions that differ for females (p < 0.05): Australia with Canary Islands and Sri Lanka; Canary Islands with Maldives, Pacific Crossing, Sea of Cortez, Seychelles and Australia; Mauritius with Sea of Cortez and Seychelles; Cocos with Sea of Cortez; and Sri Lanka with Sea of Cortez, Seychelles and Pacific Crossing.
