VCF from: Genetic evidence of female philopatry in a socially polyandrous shorebird

Sex-biased dispersal plays a key role in shaping population dynamics and genetic structure. Two main hypotheses have been proposed for how territoriality and mating competition impact sex-biased dispersal. Female-biased dispersal is expected in monogamous systems with male resource defense, whereas male-biased dispersal is expected in polygynous systems with male competition over mates. However, patterns of sex-biased dispersal in socially polyandrous species, where females compete for both territories and mates, remain poorly understood. We investigated sex-biased dispersal in two polyandrous Jacana species across Central America, the Northern Jacana (Jacana spinosa) and Wattled Jacana (J. jacana), which exhibit intense female-female competition for territories and mates and differ in the strength of sexual selection. We analyzed sex-biased dispersal by assessing genetic differentiation and individual assignment indices to determine the probability of an individual being a recent immig..., , # VCF from: Genetic evidence of female philopatry in a socially polyandrous shorebird Dataset DOI: [10.5061/dryad.tdz08kq8x](10.5061/dryad.tdz08kq8x) ## Description of the data and file structure We used genotype-by-sequencing for 271 Northern and Wattled Jacana samples from 15 localities in Costa Rica and Panama. Raw sequences were filtered and aligned to a Northern Jacana Hi-C reference genome using Stacks, BWA, and Samtools. A SNP catalog was generated, and putative hybrids were excluded to avoid confounding effects. Attempts to identify uniparental markers were limited by the sequencing approach, yielding few W-linked SNPs and no mitochondrial DNA. After excluding sex-linked scaffolds, we created four VCF files (males and females per species) and applied filtering for allele frequency, linkage disequilibrium, indels, and missing data. ### Files and variables #### File: jacana\_jacana\_female.recode.vcf **Description:**Â Filtered VCF containing biallelic SNPs with a minor allele...,性偏扩散在塑造种群动态与遗传结构中发挥关键作用。目前已提出两种主流假说，用以阐释领地性与交配竞争如何影响性偏扩散模式：在雄性资源防御的单配制体系中，预期会出现雌性偏扩散；而在雄性争夺配偶的多配制体系中，则预期会出现雄性偏扩散。然而，在雌性同时争夺领地与配偶的社会一妻多夫制物种中，性偏扩散的模式仍鲜有研究。本研究以中美洲的两种一妻多夫水雉科物种为研究对象——北水雉（*Jacana spinosa*）与肉垂水雉（*J. jacana*），二者均存在激烈的雌-雌领地与配偶竞争，且性选择强度存在差异。我们通过评估遗传分化与个体归属指数，分析了这两个物种的性偏扩散模式，以推断个体近期迁入的概率……，# VCF文件来源：《社会一妻多夫涉禽的雌性留居遗传证据》（Genetic evidence of female philopatry in a socially polyandrous shorebird） 数据集DOI: 10.5061/dryad.tdz08kq8x ## 数据与文件结构说明 我们对哥斯达黎加与巴拿马15个采样点的271份北水雉和肉垂水雉样本开展了基因型测序（genotype-by-sequencing, GBS）。原始序列经过滤后，使用Stacks、BWA与Samtools软件比对至北水雉的Hi-C参考基因组。随后构建单核苷酸多态性（Single Nucleotide Polymorphism, SNP）位点目录，并排除疑似杂交个体以规避混淆效应。受测序方法限制，单亲本标记的筛选难度较大，仅获得少量W连锁SNP位点，未获取到线粒体DNA（mitochondrial DNA）序列。在剔除性连锁支架序列（scaffolds）后，我们生成了4个VCF文件（对应两个物种的雌雄个体），并对等位基因频率、连锁不平衡、插入缺失（insertions-deletions, indels）及缺失数据进行了过滤。 ### 文件与变量 #### 文件：jacana_jacana_female.recode.vcf **描述：** 经过滤的双等位基因SNP位点VCF文件，包含次要等位基因……
