anonymous 16352 In situ photographs documenting phenotypic variation within and between hamlet species across their distribution range Coulmance, Floriane; Heckwolf, Melanie; Gismann, Jakob; Kafle, Tane; Domínguez-Domínguez, Omar; McMillan, W Owen; Puebla, Oscar (2026): In situ photographs documenting phenotypic variation within and between hamlet species across their distribution range [dataset]. PANGAEA, https://doi.org/10.1594/PANGAEA.974433 This dataset comprises 571 live photographs from 15 hamlet species (Hypoplectrus spp.) taken across their entire distribution range in 7 locations: US Virgin Islands, Panama, Belize, the Florida Keys (USA), Tobago, Mexico and Puerto Rico. Photographs were taken in situ underwater. This dataset was used to analyse within and between species phenotypic variation in color pattern, a polygenic trait used as mating cue for assortative mating in hamlets. 16360 https://doi.org/10.1594/PANGAEA.974433 2026-02-02T09:24:31+0000 2026 21827 21525 21528 21828 21829 21530 21830 21831 21832 21833 21534 20044 21834 21835 21836 21837 21838 21839 21840 21841 21842 21843 21844 21845 21846 21847 21848 21849 21850 21851 21852 21853 21854 21855 21856 21857 21858 21859 21860 21861 21862 21863 21864 21865 21866 21867 21868 21869 21870 21871 21872 21873 21874 21875 21876 21877 21878 21879 21880 21881 21882 21883 21884 21885 21886 21887 21888 21889 21890 21891 21892 21893 21894 21895 21896 21897 21898 21899 21900 21901 21903 21902
