Oceanic dispersal has emerged as an important factor contributing to biogeographic patterns in numerous taxa. Chameleons are a clear example of this, as they are primarily found in Africa and Madagascar, but the age of the family is post-Gondwanan break-up. A Malagasy origin for the family has been suggested, yet this hypothesis has not been tested using modern biogeographic methods with a dated phylogeny. To examine competing hypotheses of African and Malagasy origins, we generated a dated…

A phylogeny of the genus Chamaeleo with investigation of cryptic speciation

The aims of the present study were to reconstruct the ancestral 1081 biogeographic history of the genus Chamaeleo and to investigate whether there is evidence for niche partitioning between the three cryptic species within the C. dilepis complex.

A historical biogeography of megadiverse Sericini—another story “out of Africa”?

The historical biogeography of Sericini, a tribe of melolonthine scarabs comprising about 4000 species, was investigated using the most comprehensive and time‐calibrated molecular phylogeny available today.

Diversification of African Rainforest Restricted Clades: Piptostigmateae and Annickieae (Annonaceae)

African rainforests (ARFs) are species rich and occur in two main rainforest blocks: West/Central and East Africa. This diversity is suggested to be the result of recent diversification, high

Tortoise (Reptilia, Testudinidae) radiations in Southern Africa from the Eocene to the present

The phylogeny could not resolve relationships within Psammobates, indicating rapid speciation between the Late Oligocene and Early Miocene, and the Chersobius species were the last to diverge in the Early to Mid‐Miocene.

The measure of success: geographic isolation promotes diversification in Pachydactylus geckos

The results are consistent with a model in which lineages more likely to become geographically isolated diversify to a greater extent, although some patterns also resemble those expected of an adaptive radiation in which ecological divergence acts as a driver of speciation.

Unmasking alpha diversity, cladogenesis and biogeographical patterning in an ancient panarthropod lineage (Onychophora: Peripatopsidae: Opisthopatus cinctipes) with the description of five novel species

Speciation and biogeographical patterning in the velvet worm Opisthopatus cinctipes was examined under a null hypothesis that numerous discrete lineages are nested within the species. A total of 184

Given the Indian block’s ancient association with Gondwana and subsequent separation from Africa, then Madagascar, then the Seychelles, vicariance has often been invoked to explain the distribution

Cryptic diversity in Rhampholeon boulengeri (Sauria: Chamaeleonidae), a pygmy chameleon from the Albertine Rift biodiversity hotspot.




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.

Biogeographic patterns and phylogeography of dwarf chameleons (Bradypodion) in an African biodiversity hotspot

It is suggested that the origins of many present‐day lineages were founded in the Plio–Pleistocene, a time period that corresponds to the reduction of forests in the region and the establishment of the fynbos biome.

Eastward from Africa: palaeocurrent-mediated chameleon dispersal to the Seychelles islands

Divergence dating and biogeographic analyses indicate an origin by transoceanic dispersal from Africa to the Seychelles in the Eocene–Oligocene, providing the first such well-documented example and supporting novel palaeocurrent reconstructions.

Has Vicariance or Dispersal Been the Predominant Biogeographic Force in Madagascar? Only Time Will Tell

It is concluded that most of the present-day biota of Madagascar is comprised of the descendents of Cenozoic dispersers, predominantly with African origins.

Testing species-level diversification hypotheses in Madagascar: the case of microendemic Brookesia leaf chameleons.

A role for Pliocene/Pleistocene climatic fluctuations in species-level diversification of Brookesia is strongly rejected, and the central role of phylogeny is highlighted in any meaningful tests of species- level diversification theories.

Major Caribbean and Central American frog faunas originated by ancient oceanic dispersal

Molecular clock analyses reject the prevailing hypothesis that these frogs arose from land connections with North and South America and their subsequent fragmentation in the Late Cretaceous, and suggest Origin by dispersal, probably over water from South America in the early Cenozoic is more likely.

Evaluating trans-tethys migration: an example using acrodont lizard phylogenetics.

Three historical events may be responsible for the sharp faunal barrier between Southeast Asia and Australia-New Guinea, known as Wallace's line: primary vicariance caused by plate separations, secondary contact of Southeast Asian plates with Eurasia, leading to dispersal from Eurasia into Southeast Asia, and introduction of different biotic elements to Asia by way of separate Gondwanan plates.

The results provide the strongest evidence so far that overseas dispersal of amphibians exists and is no rare exception, although vicariance certainly retains much of its importance in explaining amphibian biogeography.

Mammalian biodiversity on Madagascar controlled by ocean currents

It is shown that currents could have transported the animals to the island and evidence inconsistent with the land-bridge hypothesis is highlighted, suggesting that rafting may be the dominant means of overseas dispersal in the Cenozoic era when palaeocurrent directions are properly considered.
