Data S2. Oultier Loci

Multi-locus SNP data for all individuals of known ecotype and all trawl samples at the 18 outlier loci identified in this study. Data are presented in two-row Structure format; the first column contains sample names, the second column contains a number indicating the treatment (1=stream, 2=shore, 3=trawl), the remaining columns contain genotypes with “-9” used to indicate missing data.

Sample names use the following convention:
-The first two characters indicate either the Stream (St) or Shore (Sh) ecotype.
-The second two characters indicate the sample location: Mission Creek (MK), Peachland Creek (PA), Powers Creek (PW), Penticton Creek (PN), Northeast shore (NE), Northwest shore (NW), Southeast shore (SE).
-The four characters following the underscore indicate the year that samples were collected (either 2007 or 2010).
-The final characters following the hyphen indicate the unique sample ID number for the ecotype, location, and year.
-'Tr' is used to indicate samples of unknown ecotype that were collected by trawl.

本研究鉴定得到18个异常位点（outlier loci）的多位点单核苷酸多态性（Single Nucleotide Polymorphism, SNP）数据集，涵盖所有已知生态型个体与所有拖网采样样本。数据采用双行Structure格式存储：第一列为样本名称，第二列为代表采样分组的数字（1=溪流生态型，2=岸栖生态型，3=拖网样本），其余列为基因型数据，其中“-9”用于标记缺失基因型。

样本名称遵循如下命名规则：
- 前两位字符代表生态型：St对应溪流（Stream）生态型，Sh对应岸栖（Shore）生态型；
- 后续两位字符代表采样地点：Mission Creek（MK）、Peachland Creek（PA）、Powers Creek（PW）、Penticton Creek（PN）、东北岸（NE）、西北岸（NW）、东南岸（SE）；
- 下划线后的四位字符为样本采集年份（仅为2007或2010年）；
- 连字符后的末尾字符为该生态型、采样地点及采集年份下的唯一样本编号；
- 前缀“Tr”用于标记通过拖网采集的未知生态型样本。
