Abstract
Six strains of the cosmopolitan species D. immigrans from the Australian life zone plus one from the USA, show weak sexual isolation and more rarely sexual selection. Levels of sexual isolation cannot be related to geographic distances. Assortative mating may have evolved as a byproduct of ecological divergence.
摘要
来自澳大利亚生活区域的6株世界性物种移民果蝇（D. immigrans）以及1株来自美国的该物种，表现出较弱的性隔离，且很少出现性选择。性隔离的程度与地理距离无关。选型交配可能是生态分化的副产品而进化而来。
