The FishMed database provides traits, phylogeny, current and projected species distribution of Mediterranean fishes, and associated sea surface temperature (SST) from the regional oceanic model NEMOMED8. Data for the current geographical distributions of 635 Mediterranean fish species were compiled from a published expert knowledge atlas of fishes of the northern Atlantic and the Mediterranean (FNAM) edited between 1984 and 1986 and from an updated exotic fish species list. Two future sets of projected species distributions were obtained for the middle and end of the 21st century by using an ensemble forecasting approach for 288 coastal Mediterranean fish species based on SST according to the IPPC/SRES A2 scenario implemented with the Mediterranean...

Multifaceted biodiversity hotspots of marine mammals for conservation priorities
Provedor de dados: 5
Autores: Albouy, Camille; Delattre, Valentine L.; Merigot, Bastien; Meynard, Christine N.; Leprieur, Fabien.
Aim Identifying the multifaceted biodiversity hotspots for marine mammals and their spatial overlap with human threats at the global scale. Location World-wide. Methods We compiled a functional trait database for 121 species of marine mammals characterized by 14 functional traits grouped into five categories. We estimated marine mammal species richness (SR) as well as functional (FD) and phylogenetic diversity (PD) per grid cell (1° × 1°) using the FRic index (a measure of trait diversity as the volume of functional space occupied by the species present in an assemblage) and the PD index (the amount of evolutionary history represented by a set of species), respectively. Finally, we assessed the spatial congruence of these three facets of biodiversity...

Plate tectonics drive tropical reef biodiversity dynamics
Provedor de dados: 5
Autores: 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.

Unexpected fish diversity gradients in the Amazon basin
Provedor de dados: 5
Autores: Oberdorff, Thierry; Dias, Murilo S.; Jézéquel, Céline; Albert, James S; Arantes, Caroline C.; Bigorne, Rémy; Carvajal-valleros, Fernando M.; De Wever, Aaike; Frederico, R. G.; Hidalgo, Max; Hugueny, Bernard; Leprieur, Fabien; Maldonado, Mabel; Maldonado-ocampo, Javier; Martens, Koen; Ortega, Hernan; Sarmiento, Jaime; Tedesco, Pablo A; Torrente-vilara, Gislene; Winemiller, Kirk O.; Zuanon, Jansen.
Using the most comprehensive fish occurrence database, we evaluated the importance of ecological and historical drivers in diversity patterns of subdrainage basins across the Amazon system. Linear models reveal the influence of climatic conditions, habitat size and sub-basin isolation on species diversity. Unexpectedly, the species richness model also highlighted a negative upriver-downriver gradient, contrary to predictions of increasing richness at more downriver locations along fluvial gradients. This reverse gradient may be linked to the history of the Amazon drainage network, which, after isolation as western and eastern basins throughout the Miocene, only began flowing eastward 1–9 million years (Ma) ago. Our results suggest that the main center of...

Global vulnerability of marine mammals to global warming
Provedor de dados: 5
Autores: Albouy, Camille; Delattre, Valentine; Donati, Giulia; Frölicher, Thomas L.; Albouy-boyer, Severine; Rufino, Marta; Pellissier, Loïc; Mouillot, David; Leprieur, Fabien.
Although extinctions due to climate change are still uncommon, they might surpass those caused by habitat loss or overexploitation over the next few decades. Among marine megafauna, mammals fulfill key and irreplaceable ecological roles in the ocean, and the collapse of their populations may therefore have irreversible consequences for ecosystem functioning and services. Using a trait-based approach, we assessed the vulnerability of all marine mammals to global warming under high and low greenhouse gas emission scenarios for the middle and the end of the 21st century. We showed that the North Pacific Ocean, the Greenland Sea and the Barents Sea host the species that are most vulnerable to global warming. Future conservation plans should therefore focus on...

Influence of the geography of speciation on current patterns of coral reef fish biodiversity across the Indo-Pacific
Provedor de dados: 5
Autores: Gaboriau, Theo; Leprieur, Fabien; Mouillot, David; Hubert, Nicolas.
The role of speciation processes in shaping current biodiversity patterns represents a major scientific question for ecologists and biogeographers. Hence, numerous methods have been developed to determine the geography of speciation based on co-occurrence between sister-species. Most of these methods rely on the correlation between divergence time and several metrics based on the geographic ranges of sister-taxa (i.e. overlap, asymmetry). The relationship between divergence time and these metrics has scarcely been examined in a spatial context beyond regression curves. Mapping this relationship across spatial grids, however, may unravel how speciation processes have shaped current biodiversity patterns through space and time. This can be particularly...

Spatial imprints of plate tectonics on extant richness of terrestrial vertebrates
Provedor de dados: 5
Autores: Descombes, Patrice; Leprieur, Fabien; Albouy, Camille; Heine, Christian; Pellissier, Loic.
Aim  In interaction with past climate changes, it is likely that plate tectonics contributed to the shaping of current global species diversity, but so far this has not been statistically quantified at the global level. Here, we tested whether plate tectonics since the breakup of Gondwana left an imprint on current patterns of species richness of amphibians, birds and mammals. Location  Global. Methods  We reconstructed the absolute positions of continental plates since the Early Cretaceous and used this information to derive variables of latitudinal shifts and potential exchanges among landmasses that could have modulated species richness. Using a multi-model inference approach combining both contemporary and historical variables, we quantified the...

Isolation drives taxonomic and functional nestedness in tropical reef fish faunas
Provedor de dados: 5
Autores: 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...

Geographic patterns and environmental correlates of taxonomic and phylogenetic beta diversity for large‐scale angiosperm assemblages in China
Provedor de dados: 5
Autores: Qian, Hong; Jin, Yi; Leprieur, Fabien; Wang, Xianli; Deng, Tao.
A full understanding of the origin and maintenance of β‐diversity patterns in a region requires exploring the relationships of both taxonomic and phylogenetic β‐diversity (TBD and PBD, respectively), and their respective turnover and nestedness components, with geographic and environmental distances. Here, we simultaneously investigated all these aspects of β‐diversity for angiosperms in China. Specifically, we evaluated the relative importance of environmental filtering vs dispersal limitation processes in shaping β‐diversity patterns. We found that TBD and PBD as quantified using a moving window approach decreased towards higher latitudes across the whole of China, and their turnover components were correlated with latitude more strongly than their...

Responses of coral reef fishes to past climate changes are related to life-history traits
Provedor de dados: 5
Autores: 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...

A unifying quantitative framework for exploring the multiple facets of microbial biodiversity across diverse scales
Provedor de dados: 5
Autores: Escalas, Arthur; Bouvier, Thierry; Mouchet, Maud A.; Leprieur, Fabien; Bouvier, Corinne; Troussellier, Marc; Mouillot, David.
Recent developments of molecular tools have revolutionized our knowledge of microbial biodiversity by allowing detailed exploration of its different facets and generating unprecedented amount of data. One key issue with such large datasets is the development of diversity measures that cope with different data outputs and allow comparison of biodiversity across different scales. Diversity has indeed three components: local (), regional () and the overall difference between local communities (). Current measures of microbial diversity, derived from several approaches, provide complementary but different views. They only capture the component of diversity, compare communities in a pairwise way, consider all species as equivalent or lack a mathematically...

Provedor de dados: 5
Autores: Tedesco, Pablo A; Beauchard, Olivier; Bigorne, Remy; Blanchet, Simon; Buisson, Laetitia; Conti, Lorenza; Cornu, Jean-francois; Dias, Murilo S.; Grenouillet, Gael; Hugueny, Bernard; Jezequel, Celine; Leprieur, Fabien; Brosse, Sebastien; Oberdorff, Thierry.
A growing interest is devoted to global-scale approaches in ecology and evolution that examine patterns and determinants of species diversity and the threats resulting from global change. These analyses obviously require global datasets of species distribution. Freshwater systems house a disproportionately high fraction of the global fish diversity considering the small proportion of the earth's surface that they occupy, and are one of the most threatened habitats on Earth. Here we provide complete species lists for 3119 drainage basins covering more than 80% of the Earth surface using 14953 fish species inhabiting permanently or occasionally freshwater systems. The database results from an extensive survey of native and non-native freshwater fish species...

Quantifying Phylogenetic Beta Diversity: Distinguishing between 'True' Turnover of Lineages and Phylogenetic Diversity Gradients
Provedor de dados: 5
Autores: Leprieur, Fabien; Albouy, Camille; De Bortoli, Julien; Cowman, Peter F.; Bellwood, David R.; Mouillot, David.
he evolutionary dissimilarity between communities (phylogenetic beta diversity PBD) has been increasingly explored by ecologists and biogeographers to assess the relative roles of ecological and evolutionary processes in structuring natural communities. Among PBD measures, the PhyloSor and UniFrac indices have been widely used to assess the level of turnover of lineages over geographical and environmental gradients. However, these indices can be considered as ‘broad-sense’ measures of phylogenetic turnover as they incorporate different aspects of differences in evolutionary history between communities that may be attributable to phylogenetic diversity gradients. In the present study, we extend an additive partitioning framework proposed for compositional...

Autores: 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...

Prioritizing phylogenetic diversity captures functional diversity unreliably
Provedor de dados: 5
Autores: Mazel, Florent; Pennell, Matthew W.; Cadotte, Marc W.; Diaz, Sandra; Dalla Riva, Giulio Valentino; Grenyer, Richard; Leprieur, Fabien; Mooers, Arne O.; Mouillot, David; Tucker, Caroline M.; Pearse, William D.
In the face of the biodiversity crisis, it is argued that we should prioritize species in order to capture high functional diversity (FD). Because species traits often reflect shared evolutionary history, many researchers have assumed that maximizing phylogenetic diversity (PD) should indirectly capture FD, a hypothesis that we name the "phylogenetic gambit". Here, we empirically test this gambit using data on ecologically relevant traits from &gt;15,000 vertebrate species. Specifically, we estimate a measure of surrogacy of PD for FD. We find that maximizing PD results in an average gain of 18% of FD relative to random choice. However, this average gain obscures the fact that in over one-third of the comparisons, maximum PD sets contain less FD than...

Autores: Leroy, Boris; Dias, Murilo S.; Giraud, Emilien; Hugueny, Bernard; Jézéquel, Céline; Leprieur, Fabien; Oberdorff, Thierry; Tedesco, Pablo A.
Aim To define the major biogeographical regions and transition zones for freshwater fish species. Taxon Strictly freshwater species of actinopterygian fish (i.e. excluding marine and amphidromous fish families). Methods We based our bioregionalization on a global database of freshwater fish species occurrences in drainage basins, which, after filtering, includes 11,295 species in 2,581 basins. On the basis of this dataset, we generated a bipartite (basin‐species) network upon which we applied a hierarchical clustering algorithm (the Map Equation) to detect regions. We tested the robustness of regions with a sensitivity analysis. We identified transition zones between major regions with the participation coefficient, indicating the degree to which a basin...

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...
