African Elephant (IMAGE) University of Utah Caption A female African elephant is followed by some young adults (left) in Kenya's Samburu National Reserve as other family members walk nearby (right). A six-year study by researchers from the University of Utah and Save the Elephants showed how tracking collars and analysis of chemical isotopes in elephants' tail hairs can allow detailed monitoring of their movements and diet -- useful information for conservationists working to protect the endangered animals from global warming and human encroachment.
