Site location information file, including site IDs, date of collection, and geographic coordinates.

Site, collection year, sample ID, and within population microsatellite DNA genetic diversity [sample size (N), observed heterozygosity (Ho), Hardy-Weinberg expected heterozygosity (He), allelic richness (A), rarified allelic richness (Ar), rarified number of private alleles (Ap), inbreeding effective size (Nei) and 95% confidence interval (CI)] for northern California tidewater goby populations (listed from north to south). Also included are site reference numbers for analysis using PHYLIP (1-36) and STRUCTURE (1-47).本数据集包含北加州潮间虾虎鱼（tidewater goby）种群（按北至南顺序排列）的采样位点、采样年份、样本编号，以及种群内微卫星DNA（microsatellite DNA）遗传多样性数据，具体指标包括：样本量（N）、观测杂合度（Ho）、哈迪-温伯格期望杂合度（He）、等位基因丰富度（A）、稀疏化等位基因丰富度（Ar）、稀疏化私有等位基因数量（Ap）、近交有效种群大小（Nei）及其95%置信区间（CI）。此外，数据集还附带了用于PHYLIP（1-36）与STRUCTURE（1-47）分析的位点参考编号。
