Effect of Spatial and Temporal Urban Isolation on the Genetic Diversity, Acoustic Variation, and Morphological Characteristics of an Urban Survivor Bird Species.

ABSTRACT: Urbanization modifies ecosystems by fragmenting natural habitats and increasing isolation between populations. Therefore, a reduction in gene flow among isolated populations is expected with greater distance and time since fragmentation. Changes in the structure, density, or community composition of the remaining habitats often result in species' differences in acoustic and morphological traits. However, the relationship between genetics, vocalizations, and morphological divergence in urban areas over time remains poorly understood. We analyzed ten years of genetic, acoustic, and morphological data from isolated populations of the white-eared ground-sparrow. We recorded and measured five acoustic traits, six morphological traits, and used seven microsatellites (SSRs) to compare the effect
