Phylogeny and biogeography of cichlid fishes (Teleostei: Perciformes: Cichlidae)

  title={Phylogeny and biogeography of cichlid fishes (Teleostei: Perciformes: Cichlidae)},
  author={John S. Sparks and W. Leo Smith},
Family level molecular phylogenetic analyses of cichlid fishes have generally suffered from a limited number of characters and/or poor taxonomic sampling across one or more major geographic assemblage, and therefore have not provided a robust test of early intrafamilial diversification. [] Key Result Representatives of major cichlid lineages across all geographic assemblages are included, as well as nearly twice the number of characters as any prior family-level study.

Phylogeny and age of chromidotilapiine cichlids (Teleostei: Cichlidae)

The presumption that paleogeographic patterns rather than ecological factors shaped the ancient divergence within chromidotilapiines, which predates the origin of the mega-diverse austrotilapiine lineage, comprising the majority of African cichlid species, is allowed.

Phylogeny, taxonomy, and evolution of Neotropical cichlids (Teleostei: Cichlidae: Cichlinae)

The simultaneous analysis of 6309 characters for 90 terminals resulted in the first well‐supported and resolved generic‐level phylogeny for Neotropical cichlids, supporting a Gondwanan origin for Cichlidae.

Exon-based phylogenomics strengthens the phylogeny of Neotropical cichlids and identifies remaining conflicting clades (Cichliformes: Cichlidae: Cichlinae)

A targeted-exon next-generation sequencing approach for investigating the evolutionary relationships of cichlid fishes (Cichlidae), with focus on the Neotropical subfamily Cichlinae using a set of 923 primarily single-copy exons designed through mining of the Nile tilapia genome.

Mitogenomic evaluation of the historical biogeography of cichlids toward reliable dating of teleostean divergences

It is proposed to add the biogeographic assumption of cichlid divergences by continental fragmentation as effective time constraints in dating teleostean divergence times to achieve a considerable reduction in credibility intervals in the estimated divergence times.

Phylogeny of the Cichlid Subfamily Etroplinae and Taxonomic Revision of the Malagasy Cichlid Genus Paretroplus (Teleostei: Cichlidae)

The sister-group relationship between Etroplus and Paretroplus represents a well-corroborated transoceanic link within Cichlidae, a pattern congruent with the Mesozoic fragmentation of Gondwana.

Phylogeny of the sea spiders (Arthropoda, Pycnogonida) based on direct optimization of six loci and morphology

  • 2007
This phylogeny represents a solid framework to work towards the understanding of pycnogonid systematics, providing a data set and a testable hypothesis that indicate those clades that need severe testing, especially some of the deep nodes of the pycnogsonid tree and the relationships of ammotheid and callipallenid forms.

Cenozoic Cichlids of Africa (Cichlidae: Pseudocrenilabrinae) With the Description of a New Species From the Oligocene of Somalia

Cichlid fishes are an important component of the African freshwater ecosystem and the evolution of this group has captured the interest of ichthyologists for many decades. The distribution of cichlid



Multilocus phylogeny of cichlid fishes (Pisces: Perciformes): evolutionary comparison of microsatellite and single-copy nuclear loci.

An evolutionary hypothesis of the major lineages of cichlid fishes based on DNA sequence data from two nuclear loci is presented and it is demonstrated that the two new DNA markers could be widely applied in perciform systematics.

Mitochondrial DNA Phylogeny of the Family Cichlidae: Monophyly and Fast Molecular Evolution of the Neotropical Assemblage

The cichlid phylogeny suggests drift-vicariance events, consistent with the fragmentation of Gondwana, to explain current biogeographic distributions and relative rate tests suggest that Neotropical cICHlids have experienced accelerated rates of molecular evolution.

Total evidence: molecules, morphology, and the phylogenetics of cichlid fishes.

The authors' analyses confirm the placement of Malagasy/Indian cichlids as the most basal lineages, with a sister-group relationship to the monophyletic African and Neotropical clades, and total evidence suggests that the controversial African genus Heterochromis is at the base of the African radiation.

A molecular phylogeny for aplocheiloid fishes (Atherinomorpha, Cyprinodontiformes): the role of vicariance and the origins of annualism.

This work presents a novel hypothesis of aplocheiloid relationships based on 1,009 bp of sequence data from three mitochondrial genes, and confirms the monophyly of the Neotropical family Rivulidae, while demonstrating a paraphyletic Old World assemblage.

A molecular phylogeny of four endangered Madagascar tortoises based on MtDNA sequences.

The phylogeny of four endemic tortoises in Madagascar is addressed using DNA sequences for the 12S and 16S rDNA and cyt b genes in mitochondrial DNA and concludes that the two Pyxis species are sister taxa and are imbedded in the genus Geochelone, rendering this latter genus paraphyletic.

Evolutionary conservation of microsatellite flanking regions and their use in resolving the phylogeny of cichlid fishes (Pisces: Perciformes)

The design of phylogenetically highly versatile MFR-primers will be of use not only for phylogeny reconstruction among families of perciform fishes, but also for population-level work in the thousands of species belonging to this highly species-rich suborder of fishes.

Phylogenetic Relationships among Damselfishes (Teleostei: Pomacentridae) as Determined by Mitochondrial DNA Data

The phylogenetic relationships of the family Pomacentridae were explored using mitochondrial DNA sequence data from the mitochondrial transfer RNA Phe, 12S mitochondrial ribosomal RNA, and 1510 base pairs for 23 species in 14 genera of pomacentrids and suggest that it is a polyphyletic assemblage.

First data on the molecular phylogeography of scincid lizards of the genus Mabuya.

Preliminary results indicate that Mabuya probably colonized Madagascar from Africa through the Mozambique Channel and a monophylum containing African and Malagasy taxa was strongly supported by the combined analysis.
