“…Seventeen tissue samples were collected from Madagascar as detailed in Andriantompohavana et al22 and Louis et al13,14 which represent the 17 nominal Microcebus species ( M. arnholdi , M. sambiranensis , M. mamiratra , M. margotmarshae , M. myoxinus , M. berthae , M. rufus , M. lehilahytsara , M. mittermeieri , M. tavaratra , M. jollyae , M. bongolavensis , M. ravelobensis , M. danfossi , M. murinus , M. griseorufus ). A sample was not available for the recently described M. gerpi, and thus, was not included in this study 25.…”

“…All sequences (accession numbers JX017385–JX017537) have been deposited in GenBank. Single haplotypes for COII and COIII to ND4 (PAST) mtDNA fragments representing each of the 17 recognized Microcebus species were analyzed and compared to the novel nuclear gene data set 13,14,22. Comparative sequence data was mined from three taxa as follows: O. garnettii and M. murinus from the partial genomes available from Ensembl and the draft genome for the Aye-aye, Daubentonia madagascariensis 37…”

Molecular phylogeny is a fundamental tool to understanding the evolution of all life forms. One common issue faced by molecular phylogeny is the lack of sufficient molecular markers. Here, we present PhyloMarker, a phylogenomic tool designed to find nuclear gene markers for the inference of phylogeny through multiple genome comparison. Around 800 candidate markers were identified by PhyloMarker through comparison of partial genomes of Microcebus and Otolemur. In experimental tests of 20 randomly selected markers, nine markers were successfully amplified by PCR and directly sequenced in all 17 nominal Microcebus species. Phylogenetic analyses of the sequence data obtained for 17 taxa and nine markers confirmed the distinct lineage inferred from previous mtDNA data. PhyloMarker has also been used by other projects including the herons (Ardeidae, Aves) phylogeny and the Wood mice (Muridae, Mammalia) phylogeny. All source code and sample data are made available at http://bioinfo-srv1.awh.unomaha.edu/phylomarker/.

“…In view of these perspectives, it is essential to obtain more samples from many of the 19 currently described mouse lemur species, and it will probably become necessary to revise the taxonomy of mouse lemurs again. If molecular divergence data are to remain a reliable indicator of taxonomic status or at least one of the analytical parameters that are used to delimitate mouse lemur species (following Yoder et al 2000;Louis et al 2006;Olivieri et al 2007;Andriantompohavana et al 2006;Radespiel et al 2008;Weisrock et al 2010), the boundary between the intra-and interspecific levels needs be redefined. However, even after some degree of taxonomic revision, the mouse lemurs of the Sahafina forest will certainly be recognized as a distinct taxon for the abovementioned reasons.…”

First indications of a highland specialist among mouse lemurs (Microcebus spp.) and evidence for a new mouse lemur species from eastern Madagascar

The factors that limit the distribution of the highly diverse lemur fauna of Madagascar are still debated. We visited an understudied region of eastern Madagascar, a lowland rainforest site (Sahafina, 29-230 m a.s.l.) close to the Mantadia National Park, in order to conduct a survey and collect further distributional data on mouse lemurs. We captured, measured, photographed, and sampled mouse lemurs from the Sahafina forest, performed standard phylogenetic methods based on three mitochondrial DNA genes, and conducted morphometric comparisons in order to clarify their phylogenetic position and taxonomic status. The mouse lemurs from the Sahafina forest could not be assigned to any of the known mouse lemur species and were highly divergent in all molecular analyses from all previously described species. Since they also differed morphometrically from their sister species and from their geographic neighbors, we propose species status and include a species description at the end. This study suggests that M. lehilahytsara may be the first highland specialist among all mouse lemurs. The distribution of the newly described mouse lemur is not fully known, but seems to be rather restricted and highly fragmented, which raises serious conservation concerns.

“…As previously communicated in systematic revisions of the genera Avahi , Lepilemur , Microcebus , and Propithecus , we have used a diagnostic approach that designates attributes or fixed characters based on the smallest definable Evolutionarily Significant Units (ESU) . We have concentrated our work on the primacy of pattern over process when defining species.…”

[5][6][7][8][9][10][11][12] We have concentrated our work on the primacy of pattern over process when defining species. Thus, our earlier work applied Population-Aggregate Analyses (PAA) of gene subunits from mtDNA sequence data (on average, 3,600-4,500 base pairs) according to the Phylogenetic Species Concept (PSC) sensu Wheeler and Platnick 15 or the PSC III of de Queiroz.…”

The answer to the proffered question, "What is a species?" is considered one of the fundamental issues of biological science, as well as one of the most polarizing and sometimes acrimonious problems. Dozens of species concepts have been defined, but none are universal for implementation across all taxa. Within the past thirty years, the ability to analyze DNA data has progressed to the point that multiple methodologies can be simultaneously applied to the same evolutionary questions. The use of restriction fragment length polymorphisms, microsatellites, and mitochondrial (mtDNA) and nuclear DNA (nucDNA) sequence data has unarguably changed how we look at diversity and intensified the concept debate through the proliferation of species descriptions. Over the past two decades, Madagascar's biodiversity has gone through a tremendous taxonomic expansion by the elevation of subspecies to species and through novel descriptions, especially within the nocturnal lemurs. With the tremendous continuous loss of habitat, exponential human population growth, and stochastic changes predicted over coming decades, elucidating the earth's biodiversity will never be more important than now. Here, we examine species concepts and their attendant criteria. We predict how technological advances will alter, improve and, we hope, fully consolidate the unity of thoughts related to this central topic of evolutionary biology and its numerous interconnected disciplines.
