Multilocus phylogeny and rapid radiations in Neotropical cichlid fishes (Perciformes: Cichlidae: Cichlinae).
The largest molecular phylogeny of Neotropical cichlid fishes produced to date is reported, combining data from three mitochondrial and two nuclear markers for 57 named genera and 154 species from South and Central America. Expand
It is found that diversification in the Neotropical cichlid clade and the highly diverse tribe Geophagini was consistent with diversity‐dependent, early bursts of divergence followed by decreased rates of lineage accumulation. Expand
Multilocus molecular phylogeny of the suckermouth armored catfishes (Siluriformes: Loricariidae) with a focus on subfamily Hypostominae.
Results of the analysis, which included type- and non-type species for every valid genus in Hypostominae, support the reevaluation and restriction of several historically problematic genera, including Baryancistrus, Cordylancistsrus, Hemiancistrus and Peckoltia. Expand
Evolutionary Perspectives on Seed Consumption and Dispersal by Fishes
Evidence of fruit and seed consumption by fishes is reviewed, and the evolution of frugivory and granivory using South American serrasalmids as a model is analyzed to suggest fishes can influence riparian vegetation dynamics. Expand
Habitat structural complexity and morphological diversity of fish assemblages in a Neotropical floodplain river
High species richness and evenness in structurally complex habitats has been hypothesized to be associated with niche partitioning. To test this idea, relationships between habitat structuralExpand
Fish assemblages of the Casiquiare River, a corridor and zoogeographical filter for dispersal between the Orinoco and Amazon basins
Aim The aim of this study was to determine whether the Casiquiare River functions as a free dispersal corridor or as a partial barrier (i.e. filter) for the interchange of fish species of the OrinocoExpand
Molecular phylogeny and evidence for an adaptive radiation of geophagine cichlids from South America (Perciformes: Labroidei).
Nucleotide sequences from the mitochondrial ND4 gene and the nuclear RAG2 gene were used to derive the most extensive molecular phylogeny to date for the Neotropical cichlid subfamily Geophaginae and found support for a 'Big Clade' and corroboration for Kullander's clade Acarichthyini. Expand
A time-calibrated, multi-locus phylogeny of piranhas and pacus (Characiformes: Serrasalmidae) and a comparison of species tree methods.
A comparison of species tree approaches indicates that most methods tested are consistent with results obtained by concatenation, suggesting that the gene-tree incongruence observed is mild and will not produce misleading results under simple Concatenation analysis. Expand
Diet-Morphology Correlations in the Radiation of South American Geophagine Cichlids (Perciformes: Cichlidae: Cichlinae)
Results suggest that the EBL could be an adaptation for either feeding or mouth brooding in the tribe Geophagini, but was not associated with species richness or accelerated rates of phyletic diversification. Expand
Morphology and Efficiency of a Specialized Foraging Behavior, Sediment Sifting, in Neotropical Cichlid Fishes
Findings indicate that similar feeding performance among sediment-sifting cichlids extracting invertebrate prey from shallow sediment layers reflects constraints associated with functional morphology and, to a lesser extent, phylogeny. Expand
