时间Tue Nov 15 03:24:02 2005
我想结论不该由您单方面表述
不然很多人会认为Alien species就是人为所带入的
以及您是否有於如推文中所述请问众教授才得到的结论
IUCN
"Alien species" (non-native, non-indigenous, foreign, exotic) means a
species, subspecies, or lower taxon occurring outside of its natural
range (past or present) and dispersal potential (i.e. outside the range
it occupies naturally or could not occupy without direct or indirect
introduction or care by humans) and includes any part, gametes or
propagule of such species that might survive and subsequently reproduce.
From Executive Order 13112 of February 3, 1999
establishing the National Invasive Species Council.
Section 1. Definitions.
(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.

何谓外来种
IUCN/ SSC Invasive Species Specialist Group 在西元2000年的
会议中阐述外来种的定义为:
外来种(Alien, Non-native, Non-indigenous, Foreign, Exotic species):
所指为一物种、亚种甚或更低的分类阶层的个体,包括该物种任何可以存活和繁殖的一部
分,出现在自然分布领域或扩散范围以外。
