Phylogeography, population structure and evolution of coral-eating butterflyfishes (Family Chaetodontidae, genus Chaetodon , subgenus Corallochaetodon )Waldrop, Ellen; Hobbs, Jean-Paul A.; Randall, John E.; DiBattista, Joseph; Rocha, Luiz A.; Kosaki, Randall K.; Berumen, Michael L.; Bowen, Brian W. (Wiley-Blackwell, 2016-01-11)Aim This study compares the phylogeography, population structure and evolution of four butterflyfish species in the Chaetodon subgenus Corallochaetodon, with two widespread species (Indian Ocean – C. trifasciatus and Pacific Ocean – C. lunulatus), and two species that are largely restricted to the Red Sea (C. austriacus) and north-western (NW) Indian Ocean (C. melapterus). Through extensive geographical coverage of these taxa, we seek to resolve patterns of genetic diversity within and between closely related butterflyfish species in order to illuminate biogeographical and evolutionary processes. Location Red Sea, Indian Ocean and Pacific Ocean. Methods A total of 632 individuals from 24 locations throughout the geographical ranges of all four members of the subgenus Corallochaetodon were sequenced using a 605 bp fragment (cytochrome b) of mtDNA. In addition, 10 microsatellite loci were used to assess population structure in the two widespread species. Results Phylogenetic reconstruction indicates that the Pacific Ocean C. lunulatus diverged from the Indian Ocean C. trifasciatus approximately 3 Ma, while C. melapterus and C. austriacus comprise a cluster of shared haplotypes derived from C. trifasciatus within the last 0.75 Myr. The Pacific C. lunulatus had significant population structure at peripheral locations on the eastern edge of its range (French Polynesia, Johnston Atoll, Hawai'i), and a strong break between two ecoregions of the Hawaiian Archipelago. The Indian Ocean C. trifasciatus showed significant structure only at the Chagos Archipelago in the central Indian Ocean, and the two range-restricted species showed no population structure but evidence of recent population expansion. Main conclusions Patterns of endemism and genetic diversity in Corallochaetodon butterflyfishes have been shaped by (1) Plio-Pleistocene sea level changes that facilitated evolutionary divergences at biogeographical barriers between Indian and Pacific Oceans, and the Indian Ocean and Red Sea, and (2) semi-permeable oceanographic and ecological barriers working on a shorter time-scale. The evolution of range-restricted species (Red Sea and NW Indian Ocean) and isolated populations (Hawai'i) at peripheral biogeographical provinces indicates that these areas are evolutionary incubators for reef fishes.
Blinded by the bright: a lack of congruence between colour morphs, phylogeography and taxonomy for a cosmopolitan Indo-Pacific butterflyfish, Chaetodon aurigaDiBattista, Joseph; Waldrop, Ellen; Rocha, Luiz A.; Craig, Matthew T.; Berumen, Michael L.; Bowen, Brian W. (Wiley-Blackwell, 2015-07)Aim: We assess genetic differentiation among biogeographical provinces and colour morphs of the threadfin butterflyfish, Chaetodon auriga. This species is among the most broadly distributed butterflyfishes in the world, occurring on reefs from the Red Sea and western Indian Ocean to French Polynesia and Hawai'i. The Red Sea form lacks a conspicuous 'eye-spot' on the dorsal fin, which may indicate an evolutionary distinction. Location: Red Sea, Indian Ocean and Pacific Ocean. Methods: Specimens were obtained at 17 locations (n = 358) spanning the entire range of this species. The genetic data included 669 base pairs of mitochondrial DNA (mtDNA) cytochrome b and allele frequencies at six microsatellite loci. Analysis of molecular variance, structure plots, haplotype networks and estimates of population expansion time were used to assess phylogeographical patterns. Results: Population structure was low overall, but significant and concordant between molecular markers (mtDNA: ΦST = 0.027, P < 0.001; microsatellites: FST = 0.023, P < 0.001). Significant population-level partitions were only detected at peripheral locations including the Red Sea and Hawai'i. Population expansion events in the Red Sea and Socotra are older (111,940-223,881 years) relative to all other sites (16,343-87,910 years). Main conclusions: We find little genetic evidence to support an evolutionary partition of a previously proposed Red Sea subspecies. The oldest estimate of population expansion in the Red Sea and adjacent Gulf of Aden indicates a putative refuge in this region during Pleistocene glacial cycles. The finding of population separations at the limits of the range, in the Red Sea and Hawai'i, is consistent with peripheral speciation. © 2015 John Wiley & Sons Ltd.
Functional composition of Chaetodon butterflyfishes at a peripheral and extreme coral reef location, the Persian GulfPratchett, Morgan S.; Hoey, Andrew; Feary, David A.; Bauman, Andrew G.; Burt, John A.; Riegl, Bernhard M. (Elsevier BV, 2013-07)The functional composition of reef fish assemblages is highly conserved across large biogeographic areas, but it is unknown whether assembly rules hold at biogeographical and environmental extremes for coral reefs. This study examined the functional composition of butterflyfishes in the Persian Gulf, Musandam Peninsula, and Gulf of Oman. Only five species of butterflyfishes were recorded during this study, and mostly just in the Gulf of Oman. Unlike most locations in the Indo-Pacific where butterflyfish assemblages are dominated by obligate corallivores, the only obligate corallivore recorded, Chaetodon melapterus, was rare or absent at all locations. The most common and widespread species was Chaetodon nigropunctatus, which is shown to be a facultative corallivore. The diversity of butterflyfishes in the Persian Gulf is likely to have been constrained by its' biogeographical history and isolation, but functional composition appears to be further affected by limited abundance of prey corals and harsh environmental conditions. © 2012.
