Table 1: Sample sizes of measured individuals across Caribbean populations, San Salvador Island generalist-only populations, and San Salvador Island radiating populations. Overall, we measured craniofacial traits for 188 wild-caught individuals across the Caribbean (including San Salvador Island and 496 lab-reared F2 hybrids. We measured 61 individuals from five populations (i.e., ‘Caribbean’), 85 individuals from six populations on San Salvador Island that do not contain the full radiation of pupfish species (i.e., ‘SSI generalist-only’), and 42 individuals from three of the radiating populations on San Salvador Island (i.e., ‘SSI radiation‘).
