翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Cycas micronesica ： ウィキペディア英語版 Cycas micronesica ''Cycas micronesica'' is a type of cycad found in Micronesia, the Marianas Group and the western Caroline Islands. The species, previously lumped with ''Cycas rumphii'' or ''Cycas circinalis'', was described in 1994 by Ken Hill.〔Hill, K.D. (1994). ''Cycas micronesica''. ''Australian Systematic Botany'' 7: 554-556.〕 It is linked with the human degenerative disease Lytico-Bodig disease, which is similar to amyotrophic lateral sclerosis (ALS) through a neurotoxin in the seeds, which were a traditional food source on Guam until the 1960s.〔Sacks, Oliver. (1996). ''The Island of the Colour-blind''. Pan Macmillan Australia: Sydney. ISBN 0-330-35887-1〕 ==Conservation== ''Cycas micronesica'' is threatened by an introduced insect pest, the diaspidid scale ''Aulacaspis yasumatsui'', first recognised in Guam in December 2003.〔Terry, Irene; & Marler, Thomas. (2005). Paradise Lost? Tipping the scales against Guam’s ''Cycas micronesica''. ''The Cycad Newsletter'' 28(3-4): 21-23.〕 Because of this the species is considered to be endangered.〔 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「Cycas micronesica」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.
