Adult and larval traits as determinants of geographic range size among tropical reef fishes ArchiMer
Luiz, Osmar J.; Allen, Andrew P.; Robertson, D. Ross; Floeter, Sergio R.; Kulbicki, Michel; Vigliola, Laurent; Becheler, Ronan; Madin, Joshua S..
Most marine organisms disperse via ocean currents as larvae, so it is often assumed that larval-stage duration is the primary determinant of geographic range size. However, empirical tests of this relationship have yielded mixed results, and alternative hypotheses have rarely been considered. Here we assess the relative influence of adult and larval-traits on geographic range size using a global dataset encompassing 590 species of tropical reef fishes in 47 families, the largest compilation of such data to date for any marine group. We analyze this database using linear mixed-effect models to control for phylogeny and geographical limits on range size. Our analysis indicates that three adult traits likely to affect the capacity of new colonizers to survive...

Distributions of Indo-Pacific lionfishes Pterois spp. in their native ranges: implications for the Atlantic invasion ArchiMer
Kulbicki, Michel; Beets, James; Chabanet, Pascale; Cure, Katherine; Darling, Emily; Floeter, Sergio R.; Galzin, Rene; Green, Alison; Harmelin-vivien, Mireille; Hixon, Mark; Letourneur, Yves; De Loma, Thierry Lison; Mcclanahan, Tim; Mcilwain, Jennifer; Moutham, Gerard; Myers, Robert; O'Leary, Jennifer K.; Planes, Serge; Vigliola, Laurent; Wantiez, Laurent.
Lionfish (Pterois volitans and P. miles) have become a major concern in the western Attantie and Caribbean since their introduction in the 1980s. Invasive lionfish can reach very high population densities on coral reefs in their invaded range, yet there are few data from their native range in the Indo-Pacific for comparison. We compiled data on the geographical distribution and density of Indo-Pacific lionfishes in their native ranges from published and unpublished underwater visual censuses and field collections. We found that lionfish in their native Indo-Pacific range are unevenly distributed, with higher densities in the Indian Ocean than in the Pacific. Lionfish densities increase significantly with increasing latitude, and are significantly higher in...

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...
