摘要: A model is proposed predicting that in nectarivorous birds territorial behavior will occur above a lower threshold of nectar productivity foraging area and disappear an upper threshold. These thresholds are determined by the daily costs living nonterritorial individuals pressure competing for resource. Decline efficiency exclusiveness predicted as increases from to Hawaiian honeycreepers (Vestiaria coccinea) supported model.
