(a) "Alien species" means, with respect to a particular ecosystem, any species, including its seeds, eggs, spores, or other biological material capable of propagating that species, that is not native to that ecosystem. http://www.invasivespeciesinfo.gov/laws/execorder.shtml 外來種犯台實錄（自然生態保育協會‧聯合報發行）外來種：生物以自體移動，或經由貿易、運輸、旅行等人類活動，無意或有意地帶離原棲地，進入新的地域稱之。來勢洶洶的外來種動物裴家騏教授、祁偉廉先生野生動物保育研究所何謂外來種 IUCN/ SSC Invasive Species Specialist Group 在西元2000年的會議中闡述外來種的定義為：外來種（Alien, Non-native, Non-indigenous, Foreign, Exotic species）：所指為一物種、亞種甚或更低的分類階層的個體，包括該物種任何可以存活和繁殖的一部分，出現在自然分布領域或擴散範圍以外。台灣入侵鳥種之現況農委會特有生物研究保育中心研究員林瑞興 (1)外來種：指一物種、亞種或更低的分類群出現在其自然分布與可能擴散範圍之外，且該分類群可能存活並繁殖子嗣 -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 210.58.35.169 ※ 編輯: kalayang 來自: 210.58.35.169 (11/15 04:08)
