“…In the understudied Indo-Pacific, numerous cryptic species have been described including fishes (Colborn et al 2001, Messmer et al 2005, Hubert et al 2012, sponges (Muricy 2011), several groups of crustaceans Boyce 2006, Poore and, molluscs (Bouchet et al 2002, Pola et al 2012, echinoderms (Landry et al 2003, Hart et al 2006, Uthicke et al 2010, and jellyfishes Martin 2001, Holland et al 2004). Uncovering cryptic species, either as sibling species or as species flocks, allows rare insights into the processes driving speciation in marine environments, especially where species cooccur without evidence of strong vicariant barriers .…”

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.

“…Subsequently, multilocus analyses appeared utilizing a variety of nuclear and mitochondrial markers to unravel phylogenetic relationships within Opisthobranchia and subgroups (e.g. Wägele et al 2003;Grande et al 2004a, b;Vonnemann et al 2005;KlussmannKolb and Dinapoli 2006;Händeler and Wägele 2007;Händeler et al 2009;Malaquias et al 2009;Klussmann-Kolb 2010a, b, 2011;Maeda et al 2010;Pola and Gosliner 2010;Moore and Gosliner 2011;Johnson and Gosliner 2012;Pola et al 2012;Corse et al 2013;Carmona et al 2013, and many more) (Fig. 3a, b) or phylogenetic relationships of opisthobranch taxa within Euthyneura (Grande et al 2004b;Klussmann-Kolb et al 2008;Jörger et al 2010;Göbbeler and Klussmann-Kolb 2011;Dayrat et al 2011;Schrödl et al 2011a; (Fig.…”

Flashback and foreshadowing—a review of the taxon Opisthobranchia

et al. 2013

View full text Add to dashboard Cite

Opisthobranchia have experienced an unsettled taxonomic history. At the moment their taxonomy is in state of dramatic flux as recent phylogenetic studies have revealed traditional Opisthobranchia to be paraphyletic or even polyphyletic, allocating some traditional opisthobranch taxa to other groups of Heterobranchia, e.g. Pulmonata. Here we review the history of Opisthobranchia and their subgroups, explain their traditionally proposed relationships, and outline the most recent phylogenetic analyses based on various methods (morphology, single gene and multiple gene analyses, as well as genomic data). We also present a phylogenetic hypothesis on Heterobranchia that, according to the latest results, represents a consensus and is the most probable one available to date. The proposed phylogeny supports the Acteonoidea outside of monophyletic Euthyneura, the basal euthyneuran split into Nudipleura (Nudibranchia plus Pleurobranchoidea) and the recently established taxon Tectipleura. The latter divides into the Euopisthobranchia, containing most of the major traditional opisthobranch clades, and the Panpulmonata, with a mix of the former opisthobranch, putative allogastropod and pulmonate taxa. This "new euthyneuran tree" rejects the traditional taxa Opisthobranchia and Pulmonata, and, in particular, has profound implications for preconceived textbook scenarios of opisthobranch and pulmonate evolution, which must now be reconsidered. In the absence of systematic barriers, research communities-which have traditionally investigated marine and non-marine heterobranchs separately-need to interact and finally merge for the sake of science.

“…Morphological characters may vary within the same species as the result of selective pressures and adaptation to varying environmental parameters (Wägele 2005), and the choice of taxonomically informative characteristics depends on the criteria of taxonomists (Mikkelsen 1998). Molecular techniques can palliate these limitations (Medina and Collins 2003;Wägele et al 2003;Wägele 2005;OrnelasGatdula et al 2012;Pola et al 2012;Carmona et al 2013). Mitochondrial genes have provided interesting information on the phylogeny of nudibranchs (Thöllesson 1999a(Thöllesson , b, 2000Medina et al 2001;Wollscheid-Lengeling et al 2001;Fahey 2003;Valdés 2003;Wilson and Lee 2005;Pola et al 2007;Turner and Wilson 2008;Johnson 2010;Pola and Gosliner 2010;Johnson and Gosliner 2012;Carmona et al 2013).…”

First molecular phylogeny of the subfamily Polycerinae (Mollusca, Nudibranchia, Polyceridae)

The subfamily Polycerinae includes four genera with around 46 species described to date. This subfamily is characterized by a limaciform body, which may have simple tentacular processes on the margin of the oral veil. Phylogenetic relationships between the genera of the subfamily Polycerinae (Polyceridae) have not yet been studied, and therefore, the only available information is based on morphological descriptions. The present study reports the first phylogenetic analysis of Polycerinae based on the mitochondrial genes cytochrome oxidase subunit I and the large ribosomal subunit (16S rRNA) using maximum likelihood and Bayesian methods. Our results showed that Polycerinae is monophyletic, but the relationships within the subfamily as well as within Polycera remain unresolved. A key finding of this study is that there are clearly two sympatric species of Polycera present in South Africa: Polycera capensis Quoy and Gaimard, 1824 also found in Australia and an undescribed Polycera sp. On the other hand, the studied specimens of the genus Gymnodoris were clustered within Polycerinae, reopening the problem of the systematic position of this genus. Additional genes and species of Polycerinae and Gymnodoris would provide more information and probably fully resolve this situation.
