翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Ecological death ： ウィキペディア英語版 Ecological death Ecological death is the inability of an organism to function in an ecological context, leading to death.〔Scott, G.R., and K.A. Sloman. 2004. The effects of environmental pollutants on complex fish behavior: integrating behavioural and physiological indicators of toxicity. Aquatic Toxicology 68:369-392.〕 This term can be used in many fields of biology to describe any species. In the context of aquatic toxicology, a toxic chemical, or toxicant, directly affects an aquatic organism but does not immediately kill it; instead it impairs an organism’s normal ecological functions which then lead to death or lack of offspring. The toxicant makes the organism unable to function ecologically in some way, even though it does not suffer obviously from the toxicant.〔 Ecological death may be caused by sublethal toxicological effects that can be behavioral, physiological, biochemical, or histological.〔Rand, G.M. (Ed). Fundamentals of Aquatic Toxicology: Effects, Environmental Fate, and Risk Assessment. 2nd Ed. Florida: CRC Press, 1995.〕 == Types of sublethal effects causing ecological death == Sublethal effects consist of any effects of an organism caused by a toxicant that do not include death. These effects are generally not observed well in a shorter acute toxicity test.〔 A longer, chronic toxicity test will allow enough time for these effects to appear in an organism and for them to lead to ecological death.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Ecological death」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
