Phylogenetic analysis of ca. 4500 base pairs of mitochondrial DNA sequence data reveals further genetic diversity in mouse lemurs (Microcebus) on the eastern and western coasts of Madagascar. Molecular data and phylogenetic analyses revise the previously monotypic species of eastern Madagascar, Microcebus rufus, with the description of 3 new species. Three additional Microcebus species are proposed in eastern Madagascar, along with another Microcebus species in western Madagascar. Correlating… 

Revision of the Mouse Lemurs, Microcebus (Primates, Lemuriformes), of Northern and Northwestern Madagascar with Descriptions of Two New Species at Montagne d'Ambre National Park and Antafondro Classified Forest

The Inter-River-System hypothesis concerning the biogeographic patterns of the distributions of the northern and northwestern mouse lemurs is revised according to the findings concerning the two species described here.

Exceptional diversity of mouse lemurs (Microcebus spp.) in the Makira region with the description of one new species

This study and other lemur inventories suggest that the Makira region is particularly rich in lemur species and the lack of any protected zone in this area should now attract the urgent attention of conservation stakeholders.

Two New Species of Mouse Lemurs (Cheirogaleidae: Microcebus) from Eastern Madagascar

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.

Molecular phylogenetics and conservation genetics of mouse lemurs (Microcebus spp.) in northwestern Madagascar

The presence/absence of a given species can not be simply explained by the forest type and that microhabitat preferences need to be considered, and a new phylogeographic hypothesis is proposed that aims to explain the speciation process that lead to the present distribution of mouse lemurs in Madagascar.


To analyze the diversity within the eastern population and among the eastern and western populations, cytogenetic data and mitochondrial DNA sequences from woolly lemurs are compared and Cytogenetic and mtDNA data are in agreement and confirm the distinctiveness of A. laniger and A. occidentalis.

Ecology and morphology of mouse lemurs (Microcebus spp.) in a hotspot of microendemism in northeastern Madagascar, with the description of a new species

Delimitation of cryptic species is increasingly based on genetic analyses but the integration of distributional, morphological, behavioral, and ecological data offers unique complementary insights

Genetic and morphological diversity of mouse lemurs (Microcebus spp.) in northern Madagascar: The discovery of a putative new species?

It is shown that the spatial distribution of forest‐dwelling species may be used as a proxy to reconstruct the past spatial changes in forest cover and vegetation type, and a significant correlation between climatic variables and morphology is suggested, suggesting a possible relationship between species identity, morphology, and environment.

Genetic Differentiation and Demographic History of the Northern Rufous Mouse Lemur (Microcebus tavaratra) Across a Fragmented Landscape in Northern Madagascar

The authors' analyses suggest that M. tavaratra holds average genetic diversity when compared to other mouse lemur species, and two to four genetic clusters in the study region, a pattern similar to that observed in another lemur endemic to the region (Propithecus tattersalli).



Remarkable species diversity in Malagasy mouse lemurs (primates, Microcebus).

Phylogenetic analysis of mtDNA sequence data confirms the observation that species diversity in the world's smallest living primate (genus Microcebus) has been greatly underestimated and revises established hypotheses of ecogeographic constraint for the maintenance of species boundaries in these endemic Malagasy primates.

Taxonomic Revision of Mouse Lemurs (Microcebus) in the Western Portions of Madagascar

Seven species of Microcebus from western Madagascar are recognized, including a previously synonymized species, and 3 spp.

Molecular phylogeny of the lemur family cheirogaleidae (primates) based on mitochondrial DNA sequences.

The molecular data support the generic status of Mirza coquereli and species-level divergence of M. ravelobensis, and suggest that "M. rufus" may well represent more than one species.

A molecular approach to comparative phylogeography of extant Malagasy lemurs

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.

Abundant mitochondrial DNA variation and world-wide population structure in humpback whales.

Phylogenetic reconstruction of nucleotypes and analysis of maternal gene flow show that current genetic variation is not due to postexploitation migration between oceans but is a relic of past population variability, suggesting that existing humpback whale lineages are of ancient origin.

Captive breeding, reintroduction, and the conservation genetics of black and white ruffed lemurs, Varecia variegata variegata

Genetic data were used to assess the ongoing management strategy for reintroducing individuals into the Betampona population and for introducing new founders into the ex situ population, demonstrating the utility of combining genetic information with a consideration of conservation priorities in evaluating the implementation of management strategies.

Molecular evidence for the origin of birds.

DNA sequences from four slow-evolving genes (mitochondrial 12S and 16S rRNA, tRNAVal, and nuclear alpha-enolase) now provide strong statistical support for a bird-crocodilian relationship.

Relationships among brown lemurs (Eulemur fulvus) based on mitochondrial DNA sequences.

The brown lemurs (Eulemur fulvus) include seven subspecies, whose evolutionary relationships remain contentious. In particular, it is unclear whether the Malagasy and Comorian E. f. fulvus

Phylogenetic relationships among Lemuridae (Primates): evidence from mtDNA.

The results support monophyly of Eulemur, a basal divergence of Varecia, and a sister-group relationship for Lemur/Hapalemur, and indicate that there may be more phylogenetic structure within this taxon than is indicated by current taxonomy.
