“…Here we hypothesize that female hybrids successfully crossed with the male parental species and transferred the mtDNA from one species to the other. Several factors (including selection and sterility) may limit nuclear DNA introgression, however, mtDNA introgression seems to be common in hybridization among coral reef fishes Yaakub et al, 2006). As pointed out by McCafferty et al (2002), larger sample sizes from different geographical locations may reveal the direction of the mtDNA transfer, but such an analysis falls outside the scope of the present paper.…”

“…In addition, the mtDNA of the potential hybrids contains unique mutations and are not 100% identical, indicating that hybridization is historical and not ongoing and eliminating the possibility of mislabeling or mixture of tissues or tubes. Morphological analyses have identified many reef fish hybrids (e.g., Randall et al, 1977;Pyle and Randall, 1994), and several cases have recently been confirmed by genetic analyses (van Herwerden et al, 2002;Yaakub et al, 2006), indicating that hybridization in marine fishes is not rare.…”

“…Geographical range of the parent species is based on the published reports (Allen et al 1998;Froese & Pauly 2007 The occurrence of hybridization is usually underestimated (Mallet 2005) and more cases are probably at Christmas and Cocos Islands. Hybrid individuals of many reef fishes often go undetected because they exhibit the physical appearance of one of the parent species (McMillan et al 1999;Yaakub et al 2006;Marie et al 2007). More importantly, this study examined only reef fishes, and hybridization is probable in other marine groups.…”

Marine hybrid hotspot at Indo-Pacific biogeographic border

).Studying hybridization is crucial to understanding speciation and almost all our knowledge comes from terrestrial and freshwater environments. Marine hybrids are considered rare, particularly on species-rich coral reefs. Here, we report a significant marine hybrid zone at Christmas and Cocos Islands (eastern Indian Ocean) with 11 hybrid coral reef fishes (across six families); the most recorded hybrids of any marine location. In most cases, at least one of the parent species is rare (less than three individuals per 3000 m 2 ), suggesting that hybridization has occurred because individuals of the rare species have mated with another species owing to a scarcity of conspecific partners. These islands also represent a marine suture zone where many of the hybrids have arisen through interbreeding between Indian and Pacific Ocean species. For these species, it appears that past climate changes allowed species to diverge in allopatry, while recent conditions have facilitated contact and subsequent hybridization at this Indo-Pacific biogeographic border. The discovery of the Christmas-Cocos hybrid zone refutes the notion that hybridization is lacking on coral reefs and provides a natural laboratory for testing the generality of terrestrially derived hybridization theory in the marine environment.

“…Most hybrids in contact zones studied to date show at least some morphological intermediacy with both parent species, although this is not always apparent (Pyle and Randall 1994, McMillan et al 1999, van der Meer et al 2012, von der Heyden and Connell 2012. Hybrids have been recorded in fishes, echinoderms, molluscs, and corals of the region (Lessios and Pearse 1996, Yaakub et al 2006, Richards et al 2008, Hobbs et al 2009, Montanari et al 2012, Ladner and Palumbi 2012, van der Meer et al 2012, Zigler et al 2012). …”

ABSTRACT.-Molecular tools and analyses have played pivotal roles in uncovering the processes and patterns of biodiversity in the Indian and Pacific oceans. However, integrating genetic results into management and conservation objectives has been challenging, with few examples that show practical applicability. This review aims to address some of the perceived barriers to an enhanced approach that integrates molecular data into management and conservation goals, by reviewing papers relevant to both conservation and fisheries management in the Indo-Pacific region, particularly with respect to phylogeography, connectivity, and species identification, as well as stock delineation, restoration of depleted wild stocks, mislabeled marine resources and "molecular forensics." We also highlight case studies from each of these areas that illustrate how molecular analyses are relevant to conservation and management in the IndoPacific, spanning a variety of vertebrate and invertebrate species. We discuss the application of genetic data to the design and evaluation of the effectiveness of marine protected area networks, stock delineation, and restoration and the usage of exclusion tests and parentage analyses for fisheries management. We conclude that there is a distinct need for increasing public awareness and ownership of genetically unique lineages and, ultimately, the increased inclusion of genetic research into management policy and conservation. Finally, we make a case for the importance of clear and effective communication for promoting public awareness, public ownership, and for achieving conservation goals within the region.
