摘要引入野生种群提供了一个独特的机会来研究社会互动和创始人效应对习得性发声的地理变异发展的影响。自20世纪70年代以来，引进的和尚鹦鹉（Myiopsitta monachus）数量一直在增长，其中包括孤立的和潜在的相互作用的种群。我们调查了康涅狄格州，得克萨斯州，佛罗里达和路易斯安那州的和尚鹦鹉种群的联系电话的多样性。接触呼叫结构在每个州的隔离人群之间差异显着。联系电话结构也有显着差异，在康涅狄格州沿海潜在的相互作用的巢殖民地，这些差异并没有遵循地理梯度。有限的分散距离，创始人效应，和社会学习的偏好可能会发挥作用，在呼叫结构的差异。
Abstract Introduced feral populations offer a unique opportunity to study the effects of social interaction and founder effects on the development of geographic variation in learned vocalizations. Introduced populations of Monk Parakeets (Myiopsitta monachus) have been growing in number since the 1970s, with a mixture of isolated and potentially interacting populations. We surveyed diversity in contact calls of Monk Parakeet populations in Connecticut, Texas, Florida, and Louisiana. Contact call structure differed significantly among the isolated populations in each state. Contact call structure also differed significantly among potentially interacting nest colonies in coastal Connecticut, and these differences did not follow a geographic gradient. Limited dispersal distances, founder effects, and social learning preferences may play a role in call structure differences.
