景观遗传结构在多大程度上体现了种群聚集过程中世系到达顺序的特征？由早期殖民者建立的居民种群对当地条件的快速遗传适应可能会阻止后来到达的谱系的建立，从而导致进化介导的优先效应。这可能导致定居的机会有限，在此期间，常住人口没有足够的时间通过当地适应来垄断这一小块土地。这一机会之窗的长度预计将取决于早期殖民者和移民预先适应当地栖息地条件的程度。我们提出了一个种内竞争模型的初始瞬时人口和进化动力学，量化的机会窗口建立无性物种。该模型明确地解决了进化介导的优先级效应的长期影响，通过跟踪血统，通过时间。我们的研究结果表明，早期殖民者和晚期移民之间的初始预适应的差异以及进化的速度共同决定了建立的机会窗口。我们的研究结果还表明，当地人口应该经常占主导地位的后代，只有少数早期殖民者的血统，景观遗传结构往往反映了殖民历史的遗产。
To what extent does landscape genetic structure bear the signature of arrival order of lineages during population assembly? Rapid genetic adaptation of resident populations founded by early colonists to local conditions might prevent establishment of later-arriving lineages, resulting in an evolution-mediated priority effect. This might result in a limited window of opportunity for establishment during which the resident population did not have sufficient time yet to monopolize the patch through local adaptation. The length of this window of opportunity is expected to depend on the degree to which early colonists and immigrants are preadapted to local habitat conditions. We present an intraspecific competition model of the initial transient population and evolutionary dynamics that quantifies the window of opportunity for establishment for asexual species. The model explicitly addresses the long-lasting effects of evolution-mediated priority effects by tracking lineages through time. Our results show that the difference in initial preadaptation between early colonists and late immigrants and the speed of evolution codetermine the window of opportunity for establishment. Our results also suggest that local populations should often be dominated by descendants of just a few early colonist lineages and that landscape genetic structure should often reflect the legacy of colonization history.
