A DNA barcode reference library of French Polynesian shore fishes ArchiMer
Delrieu-trottin, Erwan; Williams, Jeffrey T.; Pitassy, Diane; Driskell, Amy; Hubert, Nicolas; Viviani, Jeremie; Cribb, Thomas H.; Espiau, Benoit; Galzin, Rene; Kulbicki, Michel; De Loma, Thierry Lison; Meyer, Christopher; Mourier, Johann; Mou-tham, Gerard; Parravicini, Valeriano; Plantard, Patrick; Sasal, Pierre; Siu, Gilles; Tolou, Nathalie; Veuille, Michel; Weigt, Lee; Planes, Serge.
The emergence of DNA barcoding and metabarcoding opened new ways to study biological diversity, however, the completion of DNA barcode libraries is fundamental for such approaches to succeed. This dataset is a DNA barcode reference library (fragment of Cytochrome Oxydase I gene) for 2,190 specimens representing at least 540 species of shore fishes collected over 10 years at 154 sites across the four volcanic archipelagos of French Polynesia; the Austral, Gambier, Marquesas and Society Islands, a 5,000,000 km(2) area. At present, 65% of the known shore fish species of these archipelagoes possess a DNA barcode associated with preserved, photographed, tissue sampled and cataloged specimens, and extensive collection locality data. This dataset represents one...

A process‐based model supports an association between dispersal and the prevalence of species traits in tropical reef fish assemblages ArchiMer
Donati, Giulia Francesca Azzurra; Parravicini, Valeriano; Leprieur, Fabien; Hagen, Oskar; Gaboriau, Theo; Heine, Christian; Kulbicki, Michel; Rolland, Jonathan; Salamin, Nicolas; Albouy, Camille; Pellissier, Loïc.
Habitat dynamics interacting with species dispersal abilities could generate gradients in species diversity and prevalence of species traits when the latter are associated with species dispersal potential. Using a process‐based model of diversification constrained by a dispersal parameter, we simulated the interplay between reef habitat dynamics during the past 140 million years and dispersal, shaping lineage diversification history and assemblage composition globally. The emerging patterns from the simulations were compared to current prevalence of species traits related to dispersal for 6315 tropical reef fish species. We found a significant spatial congruence between the prevalence of simulated low dispersal values and areas with a large proportion of...

Delineating reef fish trophic guilds with global gut content data synthesis and phylogeny ArchiMer
Parravicini, Valeriano; Casey, Jordan M.; Schiettekatte, Nina M. D.; Brandl, Simon J.; Pozas-schacre, Chloé; Carlot, Jérémy; Edgar, Graham J.; Graham, Nicholas A. J.; Harmelin-vivien, Mireille; Kulbicki, Michel; Strona, Giovanni; Stuart-smith, Rick D..
Understanding species’ roles in food webs requires an accurate assessment of their trophic niche. However, it is challenging to delineate potential trophic interactions across an ecosystem, and a paucity of empirical information often leads to inconsistent definitions of trophic guilds based on expert opinion, especially when applied to hyperdiverse ecosystems. Using coral reef fishes as a model group, we show that experts disagree on the assignment of broad trophic guilds for more than 20% of species, which hampers comparability across studies. Here, we propose a quantitative, unbiased, and reproducible approach to define trophic guilds and apply recent advances in machine learning to predict probabilities of pairwise trophic interactions with high...

Global mismatch between fishing dependency and larval supply from marine reserves ArchiMer
Andrello, Marco; Guilhaumon, Francois; Albouy, Camille; Parravicini, Valeriano; Scholtens, Joeri; Verley, Philippe; Barange, Manuel; Sumaila, U. Rashid; Manel, Stephanie; Mouillot, David.
Marine reserves are viewed as flagship tools to protect exploited species and to contribute to the effective management of coastal fisheries. Yet, the extent to which marine reserves are globally interconnected and able to effectively seed areas, where fisheries are most critical for food and livelihood security is largely unknown. Using a hydrodynamic model of larval dispersal, we predict that most marine reserves are not interconnected by currents and that their potential benefits to fishing areas are presently limited, since countries with high dependency on coastal fisheries receive very little larval supply from marine reserves. This global mismatch could be reversed, however, by placing new marine reserves in areas sufficiently remote to minimize...

Historical and contemporary determinants of global phylogenetic structure in tropical reef fish faunas ArchiMer
Leprieur, Fabien; Colosio, Simona; Descombes, Patrice; Parravicini, Valeriano; Kulbicki, Michel; Cowman, Peter F.; Bellwood, David R.; Mouillot, David; Pellissier, Loic.
Identifying the main determinants of tropical marine biodiversity is essential for devising appropriate conservation measures mitigating the ongoing degradation of coral reef habitats. Based on a gridded distribution database and phylogenetic information, we compared the phylogenetic structure of assemblages for three tropical reef fish families (Labridae: wrasses, Pomacentridae: damselfishes and Chaetodontidae: butterflyfishes) using the net relatedness (NRI) and nearest taxon (NTI) indices. We then related these indices to contemporary and historical environmental conditions of coral reefs using spatial regression analyses. Higher levels of phylogenetic clustering were found for fish assemblages in the Indo-Australian Archipelago (IAA), and more...

Isolation drives taxonomic and functional nestedness in tropical reef fish faunas ArchiMer
Bender, Mariana G.; Leprieur, Fabien; Mouillot, David; Kulbicki, Michel; Parravicini, Valeriano; Pie, Marcio R.; Barneche, Diego R.; Oliveira-santos, Luiz Gustavo R.; Floeter, Sergio R..
Taxonomic nestedness, the degree to which the taxonomic composition of species-poor assemblages represents a subset of richer sites, commonly occurs in habitat fragments and islands differing in size and isolation from a source pool. However, species are not ecologically equivalent and the extent to which nestedness is observed in terms of functional trait composition of assemblages still remains poorly known. Here, using an extensive database on the functional traits and the distributions of 6316 tropical reef fish species across 169 sites, we assessed the levels of taxonomical vs functional nestedness of reef fish assemblages at the global scale. Functional nestedness was considerably more common than taxonomic nestedness, and generally associated with...

Juvenile corals underpin coral reef carbonate production after disturbance ArchiMer
Carlot, Jérémy; Kayal, Mohsen; Lenihan, Hunter S.; Brandl, Simon J.; Casey, Jordan M.; Adjeroud, Mehdi; Cardini, Ulisse; Merciere, Alexandre; Espiau, Benoit; Barneche, Diego R.; Rovere, Alessio; Hédouin, Laetitia; Parravicini, Valeriano.
Sea‐level rise is predicted to cause major damage to tropical coastlines. While coral reefs can act as natural barriers for ocean waves, their protection hinges on the ability of scleractinian corals to produce enough calcium carbonate (CaCO3) to keep up with rising sea levels. As a consequence of intensifying disturbances, coral communities are changing rapidly, potentially reducing community‐level CaCO3 production. By combining colony‐level physiology and long‐term monitoring data, we show that reefs recovering from major disturbances can produce 40% more CaCO3 than currently estimated due to the disproportionate contribution of juvenile corals. However, the buffering effect of highly productive juvenile corals is compromised by recruitment failures,...

Liste des poissons côtiers de Polynésie française ArchiMer
Siu, Gilles; Bacchet, Philippe; Bernardi, Giacomo; Brooks, Andrew J.; Carlot, Jeremy; Causse, Romain; Claudet, Joachim; Clua, Eric; Delrieu-trottin, Erwan; Espiau, Benoit; Harmelin-vivien, Mireille; Keith, Philippe; Lecchini, David; Madi-moussa, Rakamaly; Parravicini, Valeriano; Planes, Serge; Ponsonnet, Cedric; Randall, John E.; Sasal, Pierre; Taquet, Marc; Williams, Jeffrey T.; Galzin, Rene.
On the occasion of the 10th Indo-Pacific Fish Conference (http://ipfc10.criobe.pf/) to be held in Tahiti in October 2017, it seemed timely to update Randall's 1985 list of the fishes known from French Polynesia. Many studies focusing on fishes in this area have been published since 1985, but Randall's list remains the authoritative source. Herein we present an expanded species list of 1,301 fishes now known to occur in French Polynesia and we review the expeditions and information sources responsible for the over 60% increase in the number of known species since the publication of Randall's checklist in 1985. Our list of the fishes known from French Polynesia includes only those species with a reliably verifiable presence in these waters. In cases where...

Plate tectonics drive tropical reef biodiversity dynamics ArchiMer
Leprieur, Fabien; Descombes, Patrice; Gaboriau, Theo; Cowman, Peter F.; Parravicini, Valeriano; Kulbicki, Michel; Melian, Carlos J.; De Santana, Charles N.; Heine, Christian; Mouillot, David; Bellwood, David R.; Pellissier, Loic.
The Cretaceous breakup of Gondwana strongly modified the global distribution of shallow tropical seas reshaping the geographic configuration of marine basins. However, the links between tropical reef availability, plate tectonic processes and marine biodiversity distribution patterns are still unknown. Here, we show that a spatial diversification model constrained by absolute plate motions for the past 140 million years predicts the emergence and movement of diversity hotspots on tropical reefs. The spatial dynamics of tropical reefs explains marine fauna diversification in the Tethyan Ocean during the Cretaceous and early Cenozoic, and identifies an eastward movement of ancestral marine lineages towards the Indo-Australian Archipelago in the Miocene. A...

Responses of coral reef fishes to past climate changes are related to life-history traits ArchiMer
Ottimofiore, Eduardo; Albouy, Camille; Leprieur, Fabien; Descombes, Patrice; Kulbicki, Michel; Mouillot, David; Parravicini, Valeriano; Pellissier, Loic.
Coral reefs and their associated fauna are largely impacted by ongoing climate change. Unravelling species responses to past climatic variations might provide clues on the consequence of ongoing changes. Here, we tested the relationship between changes in sea surface temperature and sea levels during the Quaternary and present-day distributions of coral reef fish species. We investigated whether species-specific responses are associated with life-history traits. We collected a database of coral reef fish distribution together with life-history traits for the Indo-Pacific Ocean. We ran species distribution models (SDMs) on 3,725 tropical reef fish species using contemporary environmental factors together with a variable describing isolation from stable...

Unexpected high vulnerability of functions in wilderness areas: evidence from coral reef fishes ArchiMer
D'Agata, Stephanie; Vigliola, Laurent; Graham, Nicholas A. J.; Wantiez, Laurent; Parravicini, Valeriano; Villeger, Sebastien; Gerard Mou-tham,; Frolla, Philippe; Friedlander, Alan M.; Kulbicki, Michel; Mouillot, David.
High species richness is thought to support the delivery of multiple ecosystem functions and services under changing environments. Yet, some species might performunique functional roles while others are redundant. Thus, the benefits of high species richness in maintaining ecosystem functioning are uncertain if functions have little redundancy, potentially leading to high vulnerability of functions. We studied the natural propensity of assemblages to be functionally buffered against loss prior to fishing activities, using functional trait combinations, in coral reef fish assemblages across unfished wilderness areas of the Indo-Pacific: Chagos Archipelago, New Caledonia and French Polynesia. Fish functional diversity in these wilderness areas is highly...
