Home range

Japanese: 行動圏 - こうどうけん（英語表記）home range

Also called home range. A useful concept when trying to understand the spatial structure of an animal population. A term defined by W.H. Burt (1940) as "the residential area within which each individual animal moves for normal activities such as gathering food, reproducing, and raising young." This concept is mainly used for small mammals such as rodents, and includes the nest, which is the center of their life. Later, when this concept was applied to sedentary animals in general, there were cases where they did not have nests or it was difficult to determine which behaviors were normal, so the term came to be defined more broadly as "the maximum range of activity within a limited period of time of a sedentary animal."

Japanese:

行動域ともいう。動物個体群がどのような空間構造を有しているのかを知ろうとするとき有効な概念。バートW.H.Burtが動物の〈各個体が食物集め，生殖，子育てなどの正常活動のために動きまわる居住地域〉として定義(1940)した用語。これは主としてネズミ類など小哺乳類にもちいられる概念であり，その中に生活の中心地である巣がふくまれる。その後，この概念を定住性の強い動物一般にあてはめたとき，巣がないとか，行動のどれが正常活動なのか判断がむずかしいといった場合がでてきて，もっと広義に〈定住性が強い動物の，ある限られた期間内における最大行動範囲〉とされるようになった。
