N = total number of samples for each geographic region; n-pop = number of samples included in the analysis of population structure (all alongshore/inshore samples from the Gulf of Mexico [United States] were pooled, all alongshore [53] and inshore ecotype samples [13] from the Bahamas were pooled); H = number of haplotypes; h = haplotype diversity; π = nucleotide diversity. θS (Tajima 1989), and θπ (Tajima 1983). The Northwest Atlantic alongshore samples (NWAa) ranged from Georgia to New Jersey and the offshore samples (NWAo) were collected 160–480 km offshore this same stretch of coastline (Hoelzel, Potter, et al. 1998). TCS = samples included in statistical parsimony analysis (colors corresponding to those used to indicate geographic sampling region in Figure 2 are shown in parentheses). 1 = this study, 2 = Hoelzel, Potter, et al. (1998), 3 = Natoli et al. (2004), 4 = Sellas et al. (2005), 5 = Caballero et al. (2012), and 6 = Parsons et al. (2006). See Caballero et al. (2012) for description of inshore ecotype and worldwide form. Note: according to our delineation of environments, the sampling location for individuals described as “inshore ecotype” by Caballero et al. (2012) is regarded here as coastal as it is unclear if any of these animals were located in an inshore environment as we define it.
