The hairy past: Tail hair as an indicator of behavior, ecology in horses

Life style leaves chemical traces in hair. In horses, the analysis of tail hair is especially suited as the length of the hair can provide information over a long period of time. Determining the exact period of time that corresponds to a segment of hair is not trivial. Hair does not grow at the same rate in all horses. Researchers have now solved this problem. They developed a method to correctly assign individual hair growth to seasons and thus to a specific time frame.
