Patterns of hybridization in anemonefishes may result from living in highly specialized habitats and breeding status regulated by size-based hierarchal social groups. Here, morphological, ecological and genetic analyses in Kimbe Bay, Papua New Guinea, examine the hybrid status of Amphiprion leucokranos, a nominal species and presumed hybrid between Amphiprion sandaracinos and Amphiprion chrysopterus. We test the hypothesis that habitat use and relative size differences of the parent species and hybrids determine the patterns of gene exchange. There is strong evidence that A. leucokranos is a hybrid of smaller A. sandaracinos and larger A. chrysopterus, where A. chrysopterus is exclusively the mother to each hybrid, based on mtDNA cytochrome b and multiple nDNA microsatellite loci. Overlap in habitat, depth and host anemone use was found, with hybrids intermediate to parents and cohabitation in over 25% of anemones sampled. Hybrids, intermediate in body size, colour and pattern, were classified 55% of the time as morphologically first-generation hybrids relative to parents, whereas 45% of hybrids were more A. sandaracinos-like, suggesting backcrossing. Unidirectional introgression of A. chrysopterus mtDNA into A. sandaracinos via hybrid backcrosses was found, with larger female hybrids and small male A. sandaracinos mating. Potential nDNA introgression was also evident through distinct intermediate hybrid genotypes penetrating both parent species. Findings support the hypothesis that anemonefish hierarchical behaviour, habitat use and species-specific size differences determine how hybrids form and the evolutionary consequences of hybridization.The full methodology is available in the publication shown in the Related Publications link below. &rft.creator=Gainsford, A &rft.creator=van Herwerden, L &rft.creator=Jones, G &rft.date=2014&rft.relation=http://dx.doi.org/10.1111/jeb.12557&rft.coverage=150.85079626082,-4.0899101421362 150.58304761084,-4.1460924444324 150.34580973761,-4.2820336302725 150.1623051371,-4.4843887337272 150.05049651814,-4.7333028717372 150.02132848739,-5.0043712740566 150.07765621491,-5.2710439581166 150.18100696592,-5.4853613847256 150.43888740314,-5.4055559128893 150.55128011717,-5.434835565391 150.62557653427,-5.4912121744463 150.77247557487,-5.4242032791943 150.98224762779,-5.3759990640374 151.06687527518,-5.1465553631968 151.21713604257,-4.9689390320975 151.64730504989,-4.8839713505198 151.63492263486,-4.6609440890654 151.57551719636,-4.4134979788485 151.37256839976,-4.2305152960755 151.12284658417,-4.1190033629467 150.85079626082,-4.0899101421362&rft.coverage=Kimbe Bay, Papua New Guinea (5°30′S, 150°05′E)&rft_rights=&rft_rights=CC 0: Public Domain Dedication 1.0 Universal http://creativecommons.org/publicdomain/zero/1.0&rft_subject=asymmetric behavioural isolation&rft_subject=uni-directional introgression&rft_subject=size-based hierarchy&rft_subject=reproductive barrier&rft_subject=Amphiprion chrysopterus&rft_subject=Amphiprion sandaracinos&rft_subject=ARC Centre of Excellence for Coral Reef Studies&rft_subject=Marine and Estuarine Ecology (incl.

Brief description

Data consists of 1 file:

(1) Microsatellite genotype dataset - The .xlsx file contains the allelic data for 8 microsatellite loci amplified across individuals of Amphiprion chrysopterus, Amphiprion leucokranos (hybrid), and Amphiprion sandaracinos sampled from Kimbe Bay, Papua New Guinea.

Abstract [Related Publication]: Hybridization is an important evolutionary process, with ecological and behavioural factors influencing gene exchange between hybrids and parent species. Patterns of hybridization in anemonefishes may result from living in highly specialized habitats and breeding status regulated by size-based hierarchal social groups. Here, morphological, ecological and genetic analyses in Kimbe Bay, Papua New Guinea, examine the hybrid status of Amphiprion leucokranos, a nominal species and presumed hybrid between Amphiprion sandaracinos and Amphiprion chrysopterus. We test the hypothesis that habitat use and relative size differences of the parent species and hybrids determine the patterns of gene exchange. There is strong evidence that A. leucokranos is a hybrid of smaller A. sandaracinos and larger A. chrysopterus, where A. chrysopterus is exclusively the mother to each hybrid, based on mtDNA cytochrome b and multiple nDNA microsatellite loci. Overlap in habitat, depth and host anemone use was found, with hybrids intermediate to parents and cohabitation in over 25% of anemones sampled. Hybrids, intermediate in body size, colour and pattern, were classified 55% of the time as morphologically first-generation hybrids relative to parents, whereas 45% of hybrids were more A. sandaracinos-like, suggesting backcrossing. Unidirectional introgression of A. chrysopterus mtDNA into A. sandaracinos via hybrid backcrosses was found, with larger female hybrids and small male A. sandaracinos mating. Potential nDNA introgression was also evident through distinct intermediate hybrid genotypes penetrating both parent species. Findings support the hypothesis that anemonefish hierarchical behaviour, habitat use and species-specific size differences determine how hybrids form and the evolutionary consequences of hybridization.
