Eocene ocean currents and prevailing winds correlate with over‐water dispersals of terrestrial mammals from Africa to Madagascar. Since the Early Miocene (about 23 Ma), these currents flowed in the reverse direction, from the Indian Ocean towards Africa. The Comoro Islands are equidistant between Africa and Madagascar and support an endemic land vertebrate fauna that shares recent ancestry predominantly with Madagascar. We examined whether gene flow in two Miniopterus bat species endemic to the… 

Spatial and temporal arrival patterns of Madagascar's vertebrate fauna explained by distance, ocean currents, and ancestor type

Oligate rafters show a decrease in probability of successful transoceanic dispersal from the Paleocene onward, reaching the lowest levels after the mid-Miocene, consistent with a paleoceanographic model that predicts Early Cenozoic surface currents periodically conducive to rafting or swimming from Africa.

Effect of oceanic straits on gene flow in the recently endangered little brown bat (Myotis lucifugus) in maritime Canada: implications for the spread of white-nose syndrome.

High levels of genetic diversity and little population structure are found in the little brown bat, with ≈13-fold higher differentiation of mtDNA than nDNA markers, suggesting that structuring patterns largely result from female philopatry.

Genetic diversity and differentiation among insular honey bee populations in the southwest Indian Ocean likely reflect old geographical isolation and modern introductions

Comprehensive mitochondrial screening confirmed that honey bees from La Réunion, Mauritius, and Comoros archipelagos are mainly of African origin and that coexistence with European lineages occurs only in the Mascarenes, and PCA, Bayesian, and genetic differentiation analysis showed that African colonies are not significantly distinct on each island, but have diversified among islands and archipelago.

Insights into the Evolution of a Cryptic Radiation of Bats: Dispersal and Ecological Radiation of Malagasy Miniopterus (Chiroptera: Miniopteridae)

Using the mitochondrial cytochrome-b gene, a phylogeny of the Malagasy members of this widespread Old World genus is presented, based on 218 sequences, of which 82 are new and 136 derived from previous studies, which indicates much greater differentiation than currently recognized for MalagASY Miniopterus.

Analysis of genotype sequence data reveals the origin and evolutionary separation of Hawaiian hoary bat populations.

Phylogenetic analysis indicates Maui is central to the radiation across the archipelago, with the southward expansion to Hawai'i and westward to O'ahu and Kaua'i, and a single ancestral colonization event 1.34 Mya.

Evolutionary History of Indian Ocean Nycteribiid Bat Flies Mirroring the Ecology of Their Hosts

Fly species diversity sampled on Madagascar and the Comoros for two cave-roosting bat genera with contrasting ecologies are described, revealing that nycteribiids associated with Miniopterus bats comprise three species largely shared by most host species.

The Generation of a Biodiversity Hotspot: Biogeography and Phylogeography of the Western Indian Ocean Islands

The importance of islands in revealing evolutionary processes was highlighted already at the birth of evolutionary biology as a science (Darwin 1859; Darwin and Wallace 1858). Since the thrilling

Partial support for the classical ring species hypothesis in the Chaerephon pumilus species complex (Chiroptera: Molossidae) from southeastern Africa and western Indian Ocean islands

It is proposed that a source population on mainland Africa may have migrated in two directions across the Mozambique Channel, a potential barrier to gene flow, differentiating into C. pusillus and C. leucogaster on Madagascar, and then migrated to the Comoros, where it occurs in sympatry with C. pumilus s.l.

Identification of cryptic species of Miniopterus bats (Chiroptera: Miniopteridae) from Madagascar and the Comoros using bioacoustics overlaid on molecular genetic and morphological characters

The present study analyzes the bioacoustics of the 11 species of Miniopterus currently recognized from the Malagasy region, with an initial identification of the 87 recorded and collected individuals based on molecular markers and certain morphological characters.

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.

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.

ORIGINAL ARTICLE: Coalescent analyses support multiple mainland‐to‐island dispersals in the evolution of Malagasy Triaenops bats (Chiroptera: Hipposideridae)

Three biogeographical scenarios are considered to explain the directionality of mainland‐to‐island dispersals of an African‐Malagasy bat genus, Triaenops, including a single dispersal from Africa to Madagascar with subsequent speciation of the Malagasy species, excluding vicariance as a viable hypothesis.

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.

Dispersal is fundamental to biogeography and the evolution of biodiversity on oceanic islands

The importance of continuing research on mechanisms generating oceanic island biodiversity, especially detection of general, non-random patterns of dispersal, is stressed, and the need to acknowledge oceanic dispersal as significant and worthy of research is acknowledged.

The biogeography of Miniopterus bats (Chiroptera: Miniopteridae) from the Comoro Archipelago inferred from mitochondrial DNA

Genetic analyses based on two mitochondrial DNA markers suggest that the Comoros were colonized independently at least two or three times by ancestors from Madagascar.

Molecular estimates of divergence times between island taxa and their mainland counterparts indicate a Cenozoic origin for nearly all groups examined, and data from different sources point to an origin by over 65 million years.
