* * *▪ ecologyin ecology, any area defended by an organism or a group of similar organisms for such purposes as mating, nesting, roosting, or feeding. Most vertebrates and some invertebrates, such as arthropods, including insects, exhibit territorial behaviour. Possession of a territory involves aggressive behaviour and thus contrasts with the home range, which is the area in which the animal normally lives. Home range is not associated with aggressive behaviour, although parts of the home range may be defended: in this case the defended part is the territory. The type of territory varies with the social behaviour and environmental and resource requirements of the particular species and often serves more than one function, but whatever the type, the territory acts as a spacing mechanism and a means of allocating resources among a segment of the population and denying it to others. Some authorities also consider plants or animals that secrete repulsive chemicals into their immediate environments to be territorial, because the substances space individuals of the species apart from one another.
