  Titre A biogeographical regionalization of coastal Mediterranean fishes Type Article scientifique
  Année 2015 Publication Revue Abrégée Journal of Biogeography

  Mots-Clés Beta diversity; Biogeography; bioregionalization; coastal fishes; compositional turnover; environmental gradient; historical processes; Mediterranean Sea; phylogenetic turnover; species composition  
  Résumé AimTo delineate the biogeographical regions of the continental shelf of the Mediterranean Sea based on the spatial distributions of coastal marine fishes and their evolutionary relationships, with a view to furthering our capacity to answer basic and applied biogeographical, ecological and evolutionary questions. LocationMediterranean Sea. MethodsWe used a dataset summarizing the occurrences of 203 coastal Mediterranean fishes (0.1 degrees resolution grid system) and a molecular phylogenetic tree to quantify both compositional and phylogenetic dissimilarity (or beta diversity) between cells. We then applied multivariate analyses to delineate biogeographical regions and to evaluate how they related to broad-scale environmental gradients. We also assessed the differences between the biogeographical regions identified using phylogenetic beta diversity versus those obtained using compositional beta diversity. ResultsThe bioregionalization schemes based on phylogenetic and compositional beta diversity identified broadly similar regions, each consisting of six distinct pools of coastal fishes. Clear separations between northern and southern regions were observed, as well as a disjunct between inshore and offshore areas. These beta diversity patterns were mainly related to a north-south gradient in sea-surface temperature and bathymetric constraints. Main conclusionsIncorporating phylogenetic information into the measurement of beta diversity did not offer further insights to the bioregionalization scheme based solely on compositional beta diversity. This suggests that evolutionary and historical processes played only a minor role in shaping the contemporary patterns of beta diversity in the Mediterranean coastal fish fauna. However, our results support the view that contemporary environmental conditions play a major role in determining the distribution of these species.

  Titre Cichlids of the Banc d'Arguin National Park, Mauritania: insight into the diversity of the genus Coptodon Type Article scientifique
  Année 2016 Publication Revue Abrégée J. Fish Biol.  
  Volume 88 Numéro 4 Pages (up) 1369-1393  
  Mots-Clés black-chinned tilapia; cameroon; central-africa; Cichlidae; classification; cryptic species; evolution; fishes pisces; lake ejagham; perciformes; phylogeny; teleostei cichlidae; West Africa  
  Résumé To determine the species diversity of cichlids in the Banc d'Arguin National Park (PNBA) and their phylogenetic relationships with other species in West Africa, a morphometric and meristic and molecular phylogenetic study was conducted. Both approaches not only confirm the presence of Sarotherodon melanotheron in PNBA but also demonstrate the presence of a second species from the genus Coptodon. While morphometric characteristics match the description of the Guinean tilapia Coptodon guineensis, phylogenetic reconstructions based on three mitochondrial and one nuclear DNA fragment demonstrate that C. guineensis is paraphyletic over its range. Because different lineages of C. guineensis are allopatric, the distribution of C. guineensis should be restricted to Ghana and Cote d'Ivoire. The many other lineages of this species should be considered as C. sp. aff. guineensis. (C) 2016 The Fisheries Society of the British Isles

  Titre Records of anglerfishes (Lophiiformes: Lophiidae) from the western South Pacific Ocean, with descriptions of two new species Type Article scientifique
  Année 2011 Publication Revue Abrégée Journal of Fish Biology  
  Volume 79 Numéro 7 Pages (up) 1722-1745  
  Mots-Clés Animals; Fishes; Male; Pacific Ocean; Polynesia; Species Specificity  
  Résumé Species of Lophiidae collected from the western South Pacific Ocean are examined. Nine nominal species are recognized, all but one species with their distributions extended eastwards and southwards from the western Pacific Ocean. Two new species are described from Polynesia. Lophiodes iwamotoi n. sp. is described from five specimens collected from Savannah Seamount. It is characterized by a relatively long third dorsal-fin spine (56.9-70.8% standard length, L(S)) that extends (when retracted) to between the end of the soft dorsal fin and caudal-fin base; a relatively short fifth dorsal-fin spine (10.5-13.1% L(S)); a relatively short and narrow head; 19-20 pectoral-fin rays. Lophiodes maculatus n. sp. is described from 20 specimens collected from Marquesas Islands. It is characterized by an extremely long third dorsal-fin spine (71.9-87.2% L(S)), extending well beyond the caudal-fin base; a relatively short fifth dorsal-fin spine (11.4-16.5% L(S)); 17-18 pectoral-fin rays. A key to the lophiids in the western South Pacific Ocean is provided.

  Titre Levers And Linkages: Mechanical Trade-Offs In A Power-Amplified System Type Article scientifique
  Année 2014 Publication Revue Abrégée Evolution  
  Volume 68 Numéro 7 Pages (up) 1919-1933  
  Mots-Clés amplification; Biomechanics; comparative methods; evolution; kinematic transmission; labrid fishes; mantis shrimp; modularity; morphology; phylogenetic; stomatopods; strike; trade-offs  
  Résumé Mechanical redundancy within a biomechanical system (e. g., many-to-one mapping) allows morphologically divergent organisms to maintain equivalent mechanical outputs. However, most organisms depend on the integration of more than one biomechanical system. Here, we test whether coupled mechanical systems follow a pattern of amplification (mechanical changes are congruent and evolve toward the same functional extreme) or independence (mechanisms evolve independently). We examined the correlated evolution and evolutionary pathways of the coupled four-bar linkage and lever systems in mantis shrimp (Stomatopoda) ultrafast raptorial appendages. We examined models of character evolution in the framework of two divergent groups of stomatopods-“smashers” (hammer-shaped appendages) and “spearers” (bladed appendages). Smashers tended to evolve toward force amplification, whereas spearers evolved toward displacement amplification. These findings show that coupled biomechanical systems can evolve synergistically, thereby resulting in functional amplification rather than mechanical redundancy.

  Titre Optimized fishing through periodically harvested closures Type Article scientifique
  Année 2019 Publication Revue Abrégée J. Appl. Ecol.  
  Volume 56 Numéro 8 Pages (up) 1927-1936  
  Mots-Clés bioeconomic model; conservation; coral-reef fishes; fish behaviour; fisheries management; management; marine protected areas; marine reserves; new-zealand; outcomes; periodically harvested closures; population dynamics; vulnerability; yield  
  Résumé Periodically harvested closures are a widespread, centuries-old form of fisheries management that protects fish between pulse harvests and can generate high harvest efficiency by reducing fish wariness of fishing gear. However, the ability for periodic closures to also support high fisheries yields and healthy marine ecosystems is uncertain, despite increased promotion of periodic closures for managing fisheries and conserving ecosystems in the Indo-Pacific. We developed a bioeconomic fisheries model that considers changes in fish wariness, based on empirical field research, and quantified the extent to which periodic closures can simultaneously maximize harvest efficiency, fisheries yield and conservation of fish stocks. We found that periodic closures with a harvest schedule represented by closure for one to a few years between a single pulse harvest event can generate equivalent fisheries yield and stock abundance levels and greater harvest efficiency than achievable under conventional fisheries management with or without a permanent closure. Optimality of periodic closures at maximizing the triple objective of high harvest efficiency, high fisheries yield, and high stock abundance was robust to fish life history traits and to all but extreme levels of overfishing. With moderate overfishing, there emerged a trade-off between periodic closures that maximized harvest efficiency and no-take permanent closures that maximized yield; however, the gain in harvest efficiency outweighed the loss in yield for periodic closures when compared with permanent closures. Only with extreme overfishing, where fishing under nonspatial management would reduce the stock to <= 18% of its unfished level, was the harvest efficiency benefit too small for periodic closures to best meet the triple objective compared with permanent closures. Synthesis and applications. We show that periodically harvested closures can, in most cases, simultaneously maximize harvest efficiency, fisheries yield, and fish stock conservation beyond that achievable by no-take permanent closures or nonspatial management. Our results also provide design guidance, indicating that short closure periods between pulse harvest events are most appropriate for well-managed fisheries or areas with large periodic closures, whereas longer closure periods are more appropriate for small periodic closure areas and overfished systems.
