Barrier displacement by river capture is an important mechanism for the assembly of freshwater fish faunas. The production increasingly comprehensive and rigorously dated phylogentic trees major clades fishes, along with improved resolution in historical geomorphology, provide unprecedented opportunity to develop thorough biogeographical scenarios faunal that synthesise existing knowledge detailed context future study. Pecos River southwestern North America a textbook example drainage formation provides straightforward case capture. Fishes ultimately confined middle section (Capitan area endemism) have their closest relatives Brazos, Colorado (Texas), Red rivers, which served as ancient dispersal corridors from Mississippi drainage. Capitan endemism developed association two dissolution basins that, Late Miocene, captured headwaters these rivers. In Pliocene or Early Pleistocene, endorheic was overflowed into tributary Río Grande, became lower River. nascent also harboured endemic-fish assemblage part nexus springfed rivers (ancestral Devils River, River) comprised endemism. Even after through-flowing linked areas endemism, many endemic species remained only within original giving composite fauna.

Abstract We analysed phylogenetic relationships within a major clade of Cyprinodontiformes (Teleostei) that includes five families North American killifishes. used DNA sequences from genes for 130 species, with four fossil calibrations and three secondary calibrations, to generate time-calibrated phylogeny. estimated diversification rates, ancestral areas, habitats each node. Findings were interpreted detailed biogeographical synthesis. The results indicate the arose in Eocene along Gulf México coast. speciation rate was uniform through time, except acceleration Cyprinodontidae after ~10.9 Mya. In other families, neither viviparity nor marine-to-freshwater transition associated accelerated speciation. Sea-level fluctuations might have created pump by stimulating cycles dispersal vicariance Diversification also included many cases inland immigration coastal ancestors. For upland lineages, ancient river drainages accord lineage distributions, including enigmatic disjunctions Goodeidae Fundulus. uplands occurred via barrier displacement alluvial or tectonically active landscapes. Killifishes display high environmental tolerance persist harsh, peripheral environments unsuitable most fishes. Hence, combination antiquity, adaptability, dynamic geography, persistence can explain living diversity New World

Abstract Eighty years ago, George S. Myers classified inland fishes in three divisions (primary, secondary and peripheral) based on their salinity tolerance eco‐evolutionary history. Although this classification has been followed by many fish studies, it also received considerable criticism. Here, we aim to test for differences thermal tolerance, species traits distribution patterns among the using data about 21,000 species. We found that primary have much less than peripheral species, with some displaying highest tolerances (>100 ppt). provide, first time, evidence of significant phylogenetic signal comparable magnitude conservative traits, show studied maintained or even developed contrast fishes. are most different, despite large variability observed within families, morphology life‐history traits. The ranges genetic diversity similar differ from suggesting although there is oceanic dispersal a few at evolutionary time scales, rare contemporary phenomenon. Importantly, findings outlined study, namely, rely limited data. Thus, urge additional empirical research freshwater fish, which remains largely unexplored, help clarify clades.

ABSTRACT Aim Poeciliids are ecologically important, widely used as pets, and also have value model organisms. To understand diversity within this family, we study their phylogenetic (PD) at regional local scales to delimit bioregions identify patterns of biodiversity. Location The Americas. Taxon Poeciliidae (Actinopterygii: Cyprinodontiformes). Methods We expanded an existing dated phylogeny from 164 261 species with distributional data for 1 o × latitude longitude cells (~111 km 2 ) conducted a cluster analysis (phylo‐jaccard distance) delineate bioregions. For individual cells, mapped richness (SR), (PD), weighted endemism (WE) (PE). randomisation tests map clustering over‐representation short‐branch by cell. categorical neo‐ palaeo‐endemism neo‐, palaeo‐, mixed super (mixed) endemism. Results delineated six Highest density PD occurred on the Isthmus Panamá (IOP). At grid‐cell scale, Grijalva–Usumacinta drainage is hotspot SR, PD, PE WE; IOP has high PE; Tehuantepec (IOT) WE moderately SR; western Hispaniola SR. includes palaeoendemism, while widespread in Middle America Greater Antilles. Phylogenetic widespread, whereas concentrated Chihuahuan Desert–Sierra Madre Oriental region Hispaniola, both hotspots neoendemism. Main Conclusions found diversification genera intermixed relict (mixed endemism). Furthermore, SR were strongly correlated. Centres include Oriental, IOT, (most all) drainage.
