翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Despeciation ： ウィキペディア英語版 Despeciation Despeciation is the loss of a unique species of animal due to its combining with another previously distinct species.〔(【引用サイトリンク】url=http://www.medilexicon.com/medicaldictionary.php?t=24093 )〕 It is the opposite of Speciation and is much more rare. It is similar to extinction in that there is a loss of a unique species but without the associated loss of a biological lineage. ==Example of three-spined sticklebacks== For example, Taylor et al.'s genetic analysis of three-spined sticklebacks across six lakes in southwestern British Columbia found two distinct species in 1977 and 1988 but only one combined species in data from 1997, 2000, and 2002. They concluded that external factors had imperiled the living conditions of the two species, thus eliminating the evolutionary specializations that had kept them unique. 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「Despeciation」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.
