Studies on species apart from humans, from insects to elephants, have discovered that personalities are naturally widespread. The team involves scientists from the University of South Bohemia, Czech Republic, the University of Vienna, Austria, and the University of Turku, Finland, the Czech University of Life Sciences Prague, and is headed by Bruno Esattore who is from the Department of Ethology at the Institute of Animal Science in Prague.
