Barbara Ballentine is Associate Professor at Western Carolina University. Ballentine's work focuses on the evolutionary mechanisms underlying phenotypic variation and population divergence in animals, primarily birds. Using highly-integrative and experimental approaches with both field and laboratory studies Ballentine specifically addresses how sexual selection favours reliable mating signals; how natural selection constrains the expression of mating signals and mechanisms of phenotypic (morphological and behavioural) variation between populations.
