Microsatellite data for rufous-and-white wren population genetics

Among tropical organisms, heightened habitat specialization, limited natal dispersal, and strong philopatry suggest that many species may experience reduced rates of gene flow. Diverse forms of barriers, including geographic, ecological, and behavioural barriers, further promote genetic divergence among tropical bird populations. In this study, we extend our comprehension of gene flow in tropical birds by examining population genetic structure in a widespread insectivorous songbird of the neotropics: the Rufous-and-white Wren (Thryophilus rufalbus). We explore the effects of geographic distance and habitat connectivity on genetic structure using 10 microsatellite loci and nuclear and mitochondrial sequence data. We report high levels of genetic divergence and population structure with reduced contemporary gene flow between populations over a 500 km transect in Nicaragua and Costa Rica. Mitochondrial DNA and nuclear sequence data indicate that two distinct mtDNA genetic groups came into ..., , , # Microsatellite data for rufous-and-white wren population genetics Dataset DOI: [10.5061/dryad.5dv41ns89](10.5061/dryad.5dv41ns89) ## Description of the data and file structure Microsatellite dataset that accompanies the article \"Habitat connectivity, gene flow, and population genetic structure in a Neotropical understory insectivore, the Rufous-and-white Wren\" in Ornithology: https://doi.org/10.1093/ornithology/ukac030. ### File: README.txt Abbreviated README describing the data. ### File: ORNITH-21-158_Dryad_Data_file.csv Dataset includes individuals identification for each sample, population that they were collected from, latitiude and longitude for each sampling site, and microsatellite genotyping at 10 microsatellite loci (labelled a and b as these loci are biallelic). #### Variables: * BirdID = individual name for each sample * Sex = male or female * Population = Nicaragua (NIC), Mointe Verde (MV), Rincon de la Vieja (RV), Central Valley (CV), and Santa Rosa (SR). * Lati...,在热带生物类群中，较高的生境特化水平、有限的出生地扩散能力以及强烈的出生地恋巢行为（philopatry），提示多数类群的基因流速率可能有所降低。各类障碍因子（包括地理障碍、生态障碍与行为障碍）进一步推动了热带鸟类种群间的遗传分化。本研究以新热带界广泛分布的食虫鸣禽——棕白鹪鹩（*Thryophilus rufalbus*）为研究对象，通过解析其种群遗传结构，拓展了我们对热带鸟类基因流的认知。本研究利用10个微卫星位点（microsatellite loci）以及核基因组与线粒体序列数据，探究了地理距离与生境连通性对种群遗传结构的影响。研究结果显示，在尼加拉瓜与哥斯达黎加境内500公里样带范围内的种群间，遗传分化与种群结构水平较高，且当代基因流水平有所降低。线粒体DNA（mitochondrial DNA）与核序列数据表明，两个独立的线粒体DNA遗传类群起源于…… # 棕白鹪鹩种群遗传学微卫星数据集 数据集DOI：[10.5061/dryad.5dv41ns89](10.5061/dryad.5dv41ns89) ## 数据与文件结构说明 本数据集配套发表于《Ornithology》的论文"Habitat connectivity, gene flow, and population genetic structure in a Neotropical understory insectivore, the Rufous-and-white Wren"，论文DOI：https://doi.org/10.1093/ornithology/ukac030。 ### 文件：README.txt 用于简述数据集信息的精简版说明文件。 ### 文件：ORNITH-21-158_Dryad_Data_file.csv 本数据集包含每份样本的个体标识、采样种群信息、采样位点的经纬度坐标，以及10个微卫星位点的基因分型结果（因这些位点为双等位基因位点，故以a、b标记）。 #### 变量说明： * BirdID：每份样本的个体标识 * 性别（Sex）：雄性或雌性 * 种群（Population）：尼加拉瓜（NIC）、蒙特维德（MV）、里孔德拉维耶哈（RV）、中央谷地（CV）以及圣罗莎（SR） * 纬度（Lati...）
