Fig. 2From: Tracking animal movements using biomarkers in tail hairs: a novel approach for animal geolocating from sulfur isoscapesThe observed relationship between δ34S in grass and the most recent segment of the cattle tail hair, suggesting that δ34S in the hair reflects the δ34S in the landscape and can be used as a reliable biomarker of location. Red points (slightly ‘jittered’ for clearer visualization), show the most recent segment of a tail hair (i.e. the root), and black points show the rest of the segments in the tail hairBack to article page
