Aim  Geckos (Reptilia: Squamata), due to their great age and global distribution, are excellent candidates to test hypotheses of Gondwanan vicariance against post‐Gondwanan dispersal. Our aims are: to generate a phylogeny of the sphaerodactyl geckos and their closest relatives; evaluate previous phylogenetic hypotheses of the sphaerodactyl geckos with regard to the other major gecko lineages; and to use divergence date estimates to inform a biogeographical scenario regarding Gondwanan… 

Molecular evidence for Gondwanan origins of multiple lineages within a diverse Australasian gecko radiation

This work test the hypothesis that the Australian radiation of diplodactyloid geckos (families Carphodactsylidae, DiplodACTylidae and Pygopodidae), in contrast to other endemic squamate groups, has a Gondwanan origin and comprises multiple lineages that originated before the separation of Australia from Antarctica.

From Gondwana to GAARlandia: Evolutionary history and biogeography of ogre‐faced spiders (Deinopis)

We explore the evolutionary history of the ogre‐faced spiders (Deinopis) from their Early Cretaceous origins to present day. Specifically, we investigate how vicariance and dispersal have shaped

Old but not ancient: coalescent species tree of New Caledonian geckos reveals recent post‐inundation diversification

This work uses concatenated and coalescent time‐calibrated phylogenies to test whether New Caledonian diplodactylid geckos diversified steadily following an ancient vicariance event or experienced an early burst of diversification followed by a decline in net diversification after long‐distance dispersal.

Molecular clocks keep dispersal hypotheses afloat: evidence for trans‐Atlantic rafting by rodents

This work aims to provide a more robust phylogenetic hypothesis and improve divergence‐date estimates, which are essential to assessing the null hypothesis of vicariance biogeography.

Phylogeography and diversification history of the day-gecko genus Phelsuma in the Seychelles islands

The results highlight not only the necessity of clarifying the role of ecology and interspecific interactions in this group’s morphological diversification and community assemblage, but also the importance of co-evolutionary mechanisms and their importance for appropriate conservation of island biodiversity.

A likelihood framework analysis of an island radiation: phylogeography of the Lesser Antillean gecko Sphaerodactylus vincenti, in comparison with the anole Anolis roquet

The phylogeography of the Sphaerodactylus vincenti complex is analysed and the possibility that there may be cryptic species to be revealed is explored.

Euleptes gallica Müller (Squamata: Gekkota: Sphaerodactylidae) from the Lower Miocene of North-West Bohemia, Czech Republic

This study provides the first information about occurrence of this group of gekkotan lizards in the Czech Republic, and extends its stratigraphic and geographic range.

Out of Arabia: A Complex Biogeographic History of Multiple Vicariance and Dispersal Events in the Gecko Genus Hemidactylus (Reptilia: Gekkonidae)

The history of this genus is linked with major geological events that occurred in the region within the last 30 million years, and the role of Arabia and the Horn of Africa as an important Hemidactylus diversity hotspot is highlighted.



A new fossil species of Euleptes from the early Miocene of Montaigu, France (Reptilia, Gekkonidae)

A palaeobiogeographical interpretation suggests that the modern form is a relic endemite of the western Mediterranean region which survived the extinction of its congeneric relatives by being isolated on the Corso-Sardinian microplate, which left its former position at the beginning of the Miocene.

Vicariant Origin of Malagasy Reptiles Supports Late Cretaceous Antarctic Land Bridge

The data provide strong, independently corroborated evidence for a contiguous Late Cretaceous Gondwana, exclusive of Africa and connected via Antarctica, and the first temporal evidence linking the vicariant origin of extant Malagasy vertebrates to a single geologic event.

Phylogeography of Ptychadena mascareniensis suggests transoceanic dispersal in a widespread African‐Malagasy frog lineage

The phylogenetic relationships and intraspecific genetic differentiation of the Mascarene ridged frog are explored to contribute to the understanding of transoceanic dispersal in amphibians.

Long-distance colonization and radiation in gekkonid lizards, Tarentola (Reptilia: Gekkonidae), revealed by mitochondrial DNA sequences

Partial DNA sequences derived from the mitochondrial cytochrome b and 12S rRNA genes are used to trace migration and speciation in Tarentola geckos, a primarily North African clade which has invaded many of the warmer islands in the North Atlantic Ocean.

Dating the Dipsacales: comparing models, genes, and evolutionary implications.

A wide range of divergence times that can be obtained using different methods and data sets is demonstrated, and cautions against reliance on age estimates based on only a single gene or methodology.

Dispersal vs. vicariance in the Mediterranean: historical biogeography of the Palearctic Pachydeminae (Coleoptera, Scarabaeoidea)

Although the basal diversification of Pachydeminae around the Mediterranean appears to be related to vicariance events linked to the geological formation of the Mediterranean Basin, dispersal has also played a very important role.

Evolution and biogeography of West Indian Sphaerodactylus (Sauria: Gekkonidae): a molecular approach

Allopatric speciation, perhaps due to climatic changes in the Pliocene and Pleistocene, is suggested as the primary mechanism of species formation in West Indian Sphaerodactylus.

At the feet of the dinosaurs: the early history and radiation of lizards

  • S. Evans
  • Geography, Environmental Science

  • 2003
Current understanding of the first 150 million years of squamate evolution in the light of the new data and changing ideas is examined, predicting that squamates had evolved by at least the middle Triassic, and diversified into existing major lineages before the end of this period.

Chameleon radiation by oceanic dispersal

Support for a phylogeny and area cladogram that does not fit a simple vicariant history for chameleons is shown, using molecular and morphological evidence for 52 chameleon taxa.
