“…Most notably, and despite the formal separation into Manta and Mobula, it has been suggested that Manta is nested within the genus Mobula (reviewed by Aschliman, 2014). This is based on the analysis of three out of 11 mobulids with the mitochondrial genes NADH2 and NADH4, and the nuclear genes RAG1 and SCFD2 (Aschliman et al, 2012a), and an analysis of six out of 11 mobulids with the mitochondrial gene NADH2 ; morphology (Adnet et al, 2012;Aschliman et al, 2012b;Gonzalez-Isais and Dominguez, 2004;Herman et al, 2000); and parasite evolution (Benz and Deets, 1988;Olson et al, 2010). Additionally, for several species it is still not clear whether they comprise distinct lineages or merely represent geographically separated morphological variants of the same species (Marshall and Bennett, 2010;Notarbartolo di Sciara, 1987).…”

a b s t r a c tManta and devil rays are an iconic group of globally distributed pelagic filter feeders, yet their evolutionary history remains enigmatic. We employed next generation sequencing of mitogenomes for nine of the 11 recognized species and two outgroups; as well as additional Sanger sequencing of two mitochondrial and two nuclear genes in an extended taxon sampling set. Analysis of the mitogenome coding regions in a Maximum Likelihood and Bayesian framework provided a well-resolved phylogeny. The deepest divergences distinguished three clades with high support, one containing Manta birostris, Manta alfredi, Mobula tarapacana, Mobula japanica and Mobula mobular; one containing Mobula kuhlii, Mobula eregoodootenkee and Mobula thurstoni; and one containing Mobula munkiana, Mobula hypostoma and Mobula rochebrunei. Mobula remains paraphyletic with the inclusion of Manta, a result that is in agreement with previous studies based on molecular and morphological data. A fossil-calibrated Bayesian random local clock analysis suggests that mobulids diverged from Rhinoptera around 30 Mya. Subsequent divergences are characterized by long internodes followed by short bursts of speciation extending from an initial episode of divergence in the Early and Middle Miocene (19-17 Mya) to a second episode during the Pliocene and Pleistocene (3.6 Mya -recent). Estimates of divergence dates overlap significantly with periods of global warming, during which upwelling intensity -and related high primary productivity in upwelling regions -decreased markedly. These periods are hypothesized to have led to fragmentation and isolation of feeding regions leading to possible regional extinctions, as well as the promotion of allopatric speciation. The closely shared evolutionary history of mobulids in combination with ongoing threats from fisheries and climate change effects on upwelling and food supply, reinforces the case for greater protection of this charismatic family of pelagic filter feeders.

“…As more genes are analysed, topological conflicts between phylogenies based on individual genes were revealed. Moreover, information from a single gene is often insufficient to obtain a consistent hypothesis with the natural history (de Carvalho, 1996;Compagno, 1999b;Dunn et al, 2003;McEachran & Aschliman, 2004;Ebert et al, 2013) and firm statistical support (Miyamoto & Fitch, 1995;López et al, 2006;Inoue et al, 2010;Aschliman et al, 2012a;Smith et al, 2015). As a consequence, batoids phylogeny have remained overlooked and poorly resolved simply because of the limited availability of data (Aschliman et al, 2012a;Last et al, 2016).…”

Today, access to genomic information could potentially alleviate previous problems due to sampling effects by expanding the number of characters that can be used in phylogenetic analysis, from a few thousand bp to tens of thousands base pairs (bp), from genes to genomes; with an integrative methodology from the phylogenomics -the reconstitution of evolutionary history using genomes (Eisen & Fraser, 2003;Delsuc et al, 2005;Botero-Castro et al, 2016).…”

“…To date, there have been few attempts to use molecular data to resolve batoids phylogenies (e.g., Douady et al, 2003;Aschliman et al, 2012b;Naylor et al, 2012a, b). However, there is no consensus on the interrelationships of major lineages using morphological characters due in part, to the high degree of specialization and a low degree of synapomorphies which challenges finding informative characters between extant orders Shirai, 1996;McEachran & Aschliman, 2004;Aschliman et al, 2012a).…”

“…The Superorder Batoidea is generally regarded as a monophyletic clade and a sister group to sharks (Superorder Selachimorpha) based on morphological and molecular characters (McEachran & Aschliman, 2004;Aschliman et al, 2012a). Typically, four major taxonomic Orders are recognised (Nelson et al 2016), including Rajiformes (skates), Myliobatiformes (panray, thornbacks, stingrays, eagle rays and mobulids), Torpediniformes (electric rays) and sawfishes (Pristiformes).…”

Skate-ing on thin ice: molecular ecology of longnose skates in the Southeast Pacific Ocean

Longnose skates may be one of the most vulnerable taxa of elasmobranch fishes, with documented local extinctions and population declines worldwide. Longnose skates are the main component of the commercial elasmobranch fisheries in the south-east Pacific Ocean, especially in Chilean waters where target and bycatch fisheries have led two species to the brink of collapse. The yellownose skate Zearaja chilensis and the roughskin skate Dipturus trachyderma are endemic of southern South America yet little is known about population ecology and stock structure.Additionally, the external morphology of longnose skates is remarkably similar, especially in early life stages, and a lack of accurate species identification has compromised official landings records which in turn has impacted fishery management. Overall abundance of longnose skates has declined substantially over the last decade due to intensive fishing pressure and the fishery is considered to be `fully exploited'.Based on all available information in peer-reviewed and grey literature, a comparative synthesis of the biology and ecology was conducted on Z. chilensis and D. trachyderma. A positive increase in relation to scientific knowledge over the past decade was noticeable, although several basic aspects of their biology and ecology are still missing. There is an urgent need to fill knowledge gaps on, for example, movement patterns, feeding ecology and habitat use, population size and structure, and levels of connectivity. In this study, taxonomic clarity was provided, and relevant information with regard to the biology, ecology and fisheries that interact with longnose skates was collated.Confusion of identity between longnose skates occurs to the present day. In order to address this issue, morphometric and genetic tools are provided to aid in species identification of early-life stage specimens. Thirty-seven morphometric measurements and three meristic characters were used to identify specimens. These results suggest that the number of midline, nuchal and inter-dorsal thorns could be used to discriminate between specimens of Z. chilensis and D. trachyderma. Previously, the presence of a single nuchal thorn was considered to be a feature that could be used to separate species, however, this morphological feature has proven to be variable in Z. chilensis. Additionally, partial sequences of the 16S, cox1, nadh2 and the control regions of the mitochondrial DNA were amplified and analysed for intraspecific and interspecific divergence. Amplified fragments of cox1 gene and the control region contained information to separate the target species; however, specimens of D. trachyderma and Z. chilensis were grouped indistinctly within a single clade using 16S and nadh2 fragments.-iiiThe evolutionary history of Zearaja was also explored, in a broad taxonomic context by using whole mitochondrial genomes (mitogenomes) to understand higher-level phylogenetic relationships among batoids. A data set of 56 mitogenomes of 47 batoids and four outgroups was analysed. O...
