Madagascar harbors four large adaptive radiations of endemic terrestrial mammals: lemurs, tenrecs, carnivorans, and rodents. These rank among the most spectacular examples of evolutionary diversification, but their monophyly and origins are debated. The lack of Tertiary fossils from Madagascar leaves molecular studies as most promising to solve these controversies. We provide a simultaneous reconstruction of phylogeny and age of the four radiations based on a 3.5-kb data set from three nuclear… Expand
Two New Species of Mouse Lemurs (Cheirogaleidae: Microcebus) from Eastern Madagascar
TLDR
A recent genetic analysis of mtDNA and nDNA sequence data in Malagasy mouse lemurs revealed the existence of several novel mtDNA clades based on new field sampling, and confirmed their evolutionary divergence from other mouse lemur clades, formally describing them as new species. Expand
Multiple Loci and Complete Taxonomic Sampling Resolve the Phylogeny and Biogeographic History of Tenrecs (Mammalia: Tenrecidae) and Reveal Higher Speciation Rates in Madagascar's Humid Forests.
TLDR
The results resolve the relationships among previously recalcitrant taxa, illuminate the timing and mechanisms of major biogeographic patterns in an extraordinary example of an island radiation, and permit the first comprehensive, phylogenetically consistent taxonomy of Madagascar's tenrecs. Expand
Phylogenetic and phylogeographic insights into the origin of Madagascar's shrews
TLDR
The phylogeny and phylogeography of the shrews occurring on Madagascar are examined, using the mtDNA gene ND2 and a higher-level study utilizing the 16S rRNA subunit, which strongly suggest that S. madagascariensis is in fact a junior synonym of the S. etruscus. Expand
A giant frog with South American affinities from the Late Cretaceous of Madagascar
TLDR
A recently discovered Late Cretaceous anuran is described that differs strikingly in size and morphology from extant Malagasy taxa and is unrelated either to them or to the predicted occupants of the Madagascar–Seychelles–India landmass when it separated from Africa 160 million years ago (Mya).

Brazilian marsupial frogs are diphyletic (Anura: Hemiphractidae: Gastrotheca).
Molecular phylogenetic analyses based on expanded taxonomic and geographic sampling support the monophyly of the marsupial frog genera (family Hemiphractidae), resolve six geographicallyExpand
Insights into the Evolution of a Cryptic Radiation of Bats: Dispersal and Ecological Radiation of Malagasy Miniopterus (Chiroptera: Miniopteridae)
TLDR
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. Expand
Molecular phylogeny and divergence times of Malagasy tenrecs: Influence of data partitioning and taxon sampling on dating analyses
TLDR
A timeframe of tenrec evolution built on the basis of this solid phylogenetic framework showed that morphological specializations of the tenrecs may have been affected by environmental changes caused by climatic and/or subsequent colonization events. Expand
Neoendemism in Madagascan Scaly Tree Ferns Results from Recent, Coincident Diversification Bursts
TLDR
It is shown that Madagascar's extant tree fern diversity springs from three distinct ancestors independently colonizing Madagascar in the Miocene and that these three monophyletic clades diversified in three coincident radiation bursts during the Pliocene, reaching exceptionally high diversification rates and most likely responding to a common climatic trigger. Expand
Arrival and diversification of caviomorph rodents and platyrrhine primates in South America.
TLDR
Considering both the fossil record and these molecular datings, the favored scenarios are a trans-Atlantic migration of primates from Africa at the end of the Eocene or beginning of the Oligocene, and a colonization of South America by rodents during the Middle or Late Eocene. Expand
Has Vicariance or Dispersal Been the Predominant Biogeographic Force in Madagascar? Only Time Will Tell
TLDR
It is concluded that most of the present-day biota of Madagascar is comprised of the descendents of Cenozoic dispersers, predominantly with African origins. Expand

Single origin of Malagasy Carnivora from an African ancestor
TLDR
A multi-gene phylogenetic analysis is used to show that Malagasy carnivorans are monophyletic and thus the product of a single colonization of Madagascar by an African ancestor, and that a single event cannot explain the presence of both groups in Madagascar. Expand
Origin of Madagascar's extant fauna: A perspective from amphibians, reptiles and other non‐flying vertebrates
TLDR
Analysis of phylogenetic patterns of some taxa provides indications for a scenario in which the ancestors of the Malagasy clades first arrived by transmarine dispersal from Africa at theMalagasy west coast, and in a second step a subset of them underwent species‐rich radiations into the rainforests. Expand
Molecular evolutionary relationships of three genera of nesomyinae, endemic rodent taxa from madagascar
TLDR
Complete sequences of the 12S rRNA mitochondrial gene suggest that the Malagasy nesomyinesMacrotarsomys andNesomys are monophyletic and that their sister-group among the taxa analyzed isCricetomys, a rather ancient offshoot from African ancestors whose Recent relatives are Cricetomye. Expand
Archaeobatrachian paraphyly and pangaean diversification of crown-group frogs.
TLDR
To explore central controversies on the phylogeny of Anura, nearly 4000 base pairs of mitochondrial and nuclear DNA for the major frog lineages are analyzed and likelihood-based analyses are congruent with morphological evidence in supporting a paraphyletic arrangement of archaeobatrachian frogs. Expand
Endemic African mammals shake the phylogenetic tree
TLDR
DNA sequences from three mitochondrial genes and two nuclear genes are analysed to examine relationships of insectivores to other mammals and suggest that there was an extensive African radiation from a single common ancestor that gave rise to ecologically divergent adaptive types. Expand
Arrival and diversification of caviomorph rodents and platyrrhine primates in South America.
TLDR
Considering both the fossil record and these molecular datings, the favored scenarios are a trans-Atlantic migration of primates from Africa at the end of the Eocene or beginning of the Oligocene, and a colonization of South America by rodents during the Middle or Late Eocene. Expand
A molecular approach to comparative phylogeography of extant Malagasy lemurs
TLDR
Genetic data show no significant differentiation between Malagasy and Comorian populations of these species, supporting the interpretation that both were introduced only recently to the Comoro Islands. Expand

TLDR
A phylogenetic study comprising 53 genera sequenced for four nuclear genes, GHR, BRCA1, RAG1, and c-myc, totaling up to 6400 nucleotides presents a revised classification for this largest but most unsettled mammalian superfamily. Expand
Phylogenetic relationships of bufonid frogs and tests of alternate macroevolutionary hypotheses characterizing their radiation

To examine phylogenetic relationships within Bufonidae and test these alternate hypotheses, DNA sequence data were obtained from four genes, three mitochondrial and one nuclear, from populations throughout the geographic and taxonomic breadth of the family. Expand
New frog family from India reveals an ancient biogeographical link with the Seychelles
TLDR
A burrowing frog from India that is noticeably distinct from known taxa in all anuran families is found and recognized as a new family because of its very distinct morphology and an inferred origin that is earlier than several neobatrachian families. Expand
