Table S1: Name, accession numbers, primers, SNP calls and Blast matches for 51 nuclear and 3 mitochondrial loci. Abbreviations refer to the following T. californicus populations: SD: Point Loma, San Diego, California (32º45'N, 117º15'W, n = 28); SC: Santa Cruz, California (36º57'N, 122º03'W, n = 28); PBJ: Punta Baja, Baja California (29º58'N, 115º48'W, n = 31); SUN: Sunset Beach, Washington (48º30'N, 123º00'W, n = 20); FHL: Friday Harbor Laboratories, Washington (48º33'N, 125º08'W, n = 15); LC: Leo Carillo Beach, California (34º03'N, 118º56 W, n = 20); PD: Point Dume, California (34º00'N, 118º48'W, n = 18); CAT: Catalina Island, California (33º27'N, 118 29'W, n = 19); SCI: Santa Cruz Island, California (34º03'N, 119º34'W, n = 17); RP: Royal Palms, Palos Verdes, California (33º42'N, 118º19'W, n = 13); AB: Abalone Cove, Palos Verdes, California (34º44'N, 118º19'W, n = 20); LB: Laguna Beach, California (33º33'N, 117º47'W, n = 19); OSP: Osprey Point, San Diego, California (32º44'N, 117 º15'W, n = 16); PBN: Punta Banda, Baja California (31º43'N, 116º43'W, n = 19); PMO: Punta Morro, Baja California (31º52'N, 116º40'W, n = 20); PA: Playa Altamira, Baja California (28º33'N, 114º05'W, n = 20). An 'n' indicates successful SNP calls in less than 80% of the individuals screened. Loci marked with * exhibit a deficiency of identified heterozygotes in known SD × SC F1 individuals (under-calling). 'Genbank # (primer design)' refers to the accessions from which sequencing primers were designed. 'BLAST match' shows results of a BlastX search of the NCBI protein database using these sequences; only matches with an E-value < 1 × E-5 are shown. 'Genbank # (sequence)' references the sequences from which the SNPs were identified.

Table S2: Number of inter-locus comparisions (n), map distance in cM Kosambi (Distance), standard error of map distance (SE), and LOD scores for all markers on the twelve chromosomes (Chrom). Data are shown for nauplii and adults, both including and omitting microsatellite markers. Total map lengths and map lengths corrected following [43,44] are also provided.
