Abstract

Gene flow, the movement of genes between populations, profoundly influences genetic and phenotypic homogeneity among populations. This study investigates gene flow patterns in two migratory hummingbird species, Selasphorus platycercus and Calothorax lucifer, shedding light on the intricate interplay between migration, resource availability, and genetic diversity. Using previously published information on microsatellites, we examine the genetic makeup and the movement of genes within populations. Selasphorus platycercus displays distinct genetic groups which can be associated with its migratory behaviour. Gene flow analysis suggests a higher level of connectivity among populations sharing winter ranges. In contrast, Calothorax lucifer populations exhibit genetic divergence despite overlapping winter ranges, possibly due to environmental niche adaptation and limited reproductive opportunities for dispersing individuals. While geographical distance does not explain genetic differentiation in these species, environmental niche similarities appear to facilitate gene flow. This study underscores the significance of migratory routes, resource availability, and niche adaptation in shaping gene flow dynamics in hummingbirds. Understanding these dynamics is crucial for the conservation and management of these unique avian populations.
季节性迁徙引导并促进了宽尾蜂鸟和路西法短尾蜂鸟的基因流动
基因流是种群间基因的流动,对种群间基因和表型的同质性有深刻影响。本研究调查了两种迁徙蜂鸟--Selasphorus platycercus和Calothorax lucifer--的基因流动模式,揭示了迁徙、资源可用性和遗传多样性之间错综复杂的相互作用。利用以前公布的微卫星信息,我们研究了种群内的基因构成和基因移动。Selasphorus platycercus表现出不同的基因群,这可能与其迁徙行为有关。基因流分析表明,共享冬季活动范围的种群之间具有较高的连通性。相比之下,Calothorax lucifer种群尽管冬季活动范围重叠,但却表现出遗传分化,这可能是由于环境生态位适应和分散个体的繁殖机会有限造成的。虽然地理距离不能解释这些物种的遗传分化,但环境生态位的相似性似乎促进了基因流动。这项研究强调了迁徙路线、资源可用性和生态位适应在形成蜂鸟基因流动动态中的重要作用。了解这些动态对于保护和管理这些独特的鸟类种群至关重要。

期刊介绍: Avian Biology Research provides a forum for the publication of research in every field of ornithology. It covers all aspects of pure and applied ornithology for wild or captive species as well as research that does not readily fit within the publication objectives of other ornithological journals. By considering a wide range of research fields for publication, Avian Biology Research provides a forum for people working in every field of ornithology.
