Not completely reviewed; NPSpp records takend from HALE animal species checklist (NRBib #8882). Ph.D. thesis; zoology. Investigates the population ecology of the feral pig in Kipahulu Valley, Maui. Feral history of the pig in this area is 35 years. Examines factors which might limit abundance and population processes unique to this habitat. Examines food habits to determine whether quality --rather than quantity-- of food might limit populations. The population studied was omnivorous, consuming mostly tree ferns, strawberry guava, and earthworms. The population is characterized by high juvenile mortality as a result of miring, accidents, and mongoose predation. Adult mortality was influenced by metastrongyllid and kidney worm infection. Overall lifespan is limited by failure of dentition. Estimates a population of 100-300 individuals. Management of pigs is recommended, as they disrupt native forest and assist in the introduction of exotic species such as the strawberry guava.
