Document Summary
The home range is the are that an animal normally uses over the course of a year. The size of the home range varies with: availability of food, mode of fathering food, body size, metabolic needs. Carnivores generally have larger home ranges than herbivores or omnivores. Males and adults generally have larger home ranges than females and juveniles. The area of the home range is not defended, but aggressive interactions may affect the movement of individuals within one animal"s home range. A territory is a part of the home range that an animal defends. If an animal defends its entire home range, they are the sae. By defending a territory the animal secures sole access to the habitat and its resources. Behavioural defences of a territory include: songs and calls, intimidation displays. Mammals bare their teeth: attacking and chasing intruders, scent marking to deter intruders. Territories of different individuals within a population are usually regularly distributed.
