鸟类的歌声被假设在鸣禽生物学的几个重要方面发挥作用，包括物种形成的分类多样性的产生;然而，歌声在这一群体内的物种形成中发挥的作用可能取决于种群在面对基因流动和外部文化影响时保持种群特定歌声或叫声的能力。在这里，在一个探索性的研究中，我们构建了一个空间上明确的人口流动模型，以研究唱不同歌曲的人口的二次接触的后果。我们集中在两个广泛的问题：1）人口特定的歌曲将保持在一个接触区或将被取代的共享歌曲，和2）什么样的空间模式的歌曲分布可能会导致接触？我们研究了多种因素的影响，包括基于歌曲的交配偏好和运动概率，斜与父亲学习的歌曲，文化和基因突变。我们发现了各种条件下，人口特定的歌曲可以保持，特别是当女性有自己的人口特定的歌曲的偏好，我们记录了许多不同的模式的歌曲分布在接触区，包括倾斜，带状，马赛克。
Bird song has been hypothesized to play a role in several important aspects of the biology of songbirds, including the generation of taxonomic diversity by speciation; however, the role that song plays in speciation within this group may be dependent upon the ability of populations to maintain population specific songs or calls in the face of gene flow and external cultural influences. Here, in an exploratory study, we construct a spatially explicit model of population movement to examine the consequences of secondary contact of populations singing distinct songs. We concentrate on two broad questions: 1) will population specific songs be maintained in a contact zone or will they be replaced by shared song, and 2) what spatial patterns in the distribution of songs may result from contact? We examine the effects of multiple factors including song-based mating preferences and movement probabilities, oblique versus paternal learning of song, and both cultural and genetic mutations. We find a variety of conditions under which population specific songs can be maintained, particularly when females have preferences for their population specific songs, and we document many distinct patterns of song distribution within the contact zone, including clines, banding, and mosaics.
