Action space

from Wikipedia, the free encyclopedia

In the fields of zoology and social and behavioral geography , action space refers to the size of the habitat used by an animal. In 1943, William Henry Burt described the “home range” as the area that is visited in connection with the regular activities of an animal. These activities included foraging, coping and raising young. In contrast, according to Burt, temporary stays to explore the area should not be part of the concept of the action space. The action area of ​​an animal is usually much larger than the territory , i.e. the area defended against conspecifics.

methodology

The size of the action area can be determined using various methods, the most common being the minimum convex polygon . To determine the range of action, animals are often provided with transmitters , until a few years ago it was usually with ground telemetry transmitters, whereby the whereabouts of the animal is determined by an observer with one or, ideally, several observers using cross bearings . In recent years, GPS satellite transmitters have been increasingly used, which allow continuous data acquisition without the use of field observers.
