Schoener (1968) examined the resource partitioning of anolis lizards on the Caribbean island of South Bimini. He cross-classified lizard counts in habitats (branches in trees) with respect to three variables: lizard species A. sargei and A. distichus, branch height (high and low), and branch size (small and large).
