桥头堡效应

维基百科,自由的百科全书

生态学中,桥头堡效应是指入侵物种在初次扩散至非原产地后,该入侵种群能够作为新的扩散源,再次向其他地区扩散的现象[1][2]

全球化背景下,国际贸易与人类运输网络的高度发达极大地增加了桥头堡地出现的可能性[2]。桥头堡效应被认为在入侵物种的全球扩散中普遍存在[3][4][5]

研究

[编辑]

种群遗传学的研究表明,香港、美国佛罗里达州菲律宾巴拿马均可能是温室蟾Eleutherodactylus planirostris)由原产地(古巴开曼群岛巴哈马群岛)入侵深圳的桥头堡地[6]西花蓟马Frankliniella occidentalis)在进入中国后,昆明被推测为其进一步扩散至国内其他地区的桥头堡地[7]

红火蚁Solenopsis invicta)的全球入侵史中,美国被证实为关键的桥头堡地,其最初起源于南美洲,再经由美国向多个地区扩散[8]

部分研究认为,相较于原产地种群,桥头堡地的种群可能在短期内进化出更强的入侵性,从而形成“入侵自我加速”的过程,成为全球新入侵加速的重要驱动因素之一[2][9]。目前尚缺乏确凿证据证明桥头堡地种群的成功入侵是源于侵袭性的增强,这一现象更可能与二次引入频率的增加有关[2]
