Organisms can only live within a certain range of environments. If that range is narrow, the presence of the organism can, conversely, tell us about the environment. Organisms that indicate the environment in this way are called indicator organisms, and their biological species are called indicator species. Recently, they have also been used as indicators of environmental pollution.

生物はある範囲の環境の中でのみ生活することができる。その範囲が狭い場合には、その生物の存在することにより、逆に、その環境を知ることができる。このように、その環境を示すような生物を指標生物といい、その生物種を指標種という。最近では環境汚濁の指針としても用いられる。 [村野正昭] [参照項目] |出典 小学館 日本大百科全書(ニッポニカ)日本大百科全書(ニッポニカ)について 情報 | 凡例 |
