Journal ArticleDOI
Can stable isotope ratios provide for community-wide measures of trophic structure?
TL;DR: Building from extensive applications of stable isotope ratios by ecologists, the community-wide metrics may provide a new perspective on food web structure, function, and dynamics.
Journal ArticleDOI
Systematics, biogeography, and evolution of the Neotropical peacock basses Cichla (Perciformes: Cichlidae)
Stuart C. Willis,Mario Da Silva Nunes,Carmen G. Montaña,Izeni Pires Farias,Nathan R. Lovejoy +4 more
TL;DR: Biogeographic patterns from Cichla are partially congruent with those seen in several other Neotropical fish clades, and the diversification of Cichlid species is inferred to result from both vicariance and sympatric divergence.
Journal ArticleDOI
Diet-morphology correlations in the radiation of South American geophagine cichlids (Perciformes: Cichlidae: Cichlinae).
Hernán López-Fernández,Hernán López-Fernández,Kirk O. Winemiller,Carmen G. Montaña,Rodney L. Honeycutt +4 more
TL;DR: 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.
Journal ArticleDOI
Evolutionary convergence in Neotropical cichlids and Nearctic centrarchids: evidence from morphology, diet, and stable isotope analysis
TL;DR: Consistent patterns of ecomorphological convergence in these two perciform groups provide strong evidence for adaptation involving constrains in functional morphology associated with feeding.
Journal ArticleDOI
The Casiquiare river acts as a corridor between the Amazonas and Orinoco river basins: biogeographic analysis of the genus Cichla
Stuart C. Willis,Mario Da Silva Nunes,Carmen G. Montaña,Izeni Pires Farias,Guillermo Ortí,Nathan R. Lovejoy +5 more
TL;DR: The results support the idea that the Casiquiare connection is important across temporal scales, facilitating both gene flow and the dispersal and range expansion of species.
