Data from: Patterns of macroevolution among Primates inferred from a supermatrix of mitochondrial and nuclear DNA.

Pierre-Henri Fabre, Andrew Rodrigues, Emmanuel J. P. Douzery, P-.H. Fabre, A. Rodrigues & E.J.P. Douzery
Here, we present a new primate phylogeny inferred from molecular supermatrix analyses of size 42 kb containing 70% of missing data, and representing 75% of primate species diversity. The supermatrix was analysed using a gene-partitioned maximum likelihood approach to obtain an exhaustive molecular phylogenetic framework. All clades recovered from recent molecular works were upheld in our analyses demonstrating that the presence of missing data did not bias our supermatrix inference. The resulting phylogenetic tree was...

Data from: Accelerated evolutionary rate of housekeeping genes in tunicates

Georgia Tsagkogeorga, Xavier Turon, Nicolas Galtier, Emmanuel J. P. Douzery & Frédéric Delsuc
Phylogenomics has recently revealed that tunicates represent the sister-group of vertebrates in the newly defined clade Olfactores. However, phylogenomic and comparative genomic studies have also suggested that tunicates are characterized by an elevated rate of molecular evolution and a high degree of genomic divergence. Despite the recurrent interest in the group, the picture of tunicate peculiar evolutionary dynamics is still fragmentary, as it mainly lies in studies focusing on only a few model species. In...

Data from: Phylogenetic signal in module composition and species connectivity in compartmentalized host-parasite networks

Boris R. Krasnov, Miguel A. Fortuna, David Mouillot, Irina S. Khokhlova, Georgy I. Shenbrot & Robert Poulin
Across different taxa, networks of mutualistic or antagonistic interactions show consistent architecture. Most networks are modular, with modules being distinct species subsets connected mainly with each other and having few connections to other modules. We investigate the phylogenetic relatedness of species within modules and whether a phylogenetic signal is detectable in the within- and among module connectivity of species using 27 mammal-flea networks from the Palaearctic. In the 24 networks that were modular, closely-related hosts...

Data from: Phylogenetic analyses of mitochondrial and nuclear data in haematophagous flies support the paraphyly of the genus Stomoxys (Diptera: Muscidae)

Najla Dsouli, Frédéric Delsuc, Johan Michaux, Eric De Stordeur, Arnaud Couloux, Michel Veuille & Gérard Duvallet
The genus Stomoxys Geoffroy (Diptera; Muscidae) contains species of parasitic flies that are of medical and economic importance. We conducted a phylogenetic analysis including 10 representative species of the genus including multiple exemplars, together with the closely related genera Prostomoxys Zumpt, Haematobosca Bezzi, and Haematobia Lepeletier & Serville. Phylogenetic relationships were inferred using maximum likelihood and Bayesian methods from DNA fragments from the cytochrome c oxidase subunit I (COI, 753 bp) and cytochrome b (CytB,...

Data from: New DNA data from a Transthyretin nuclear intron suggest an Oligocene to Miocene diversification of living South America opossums (Marsupialia: Didelphidae).

Cynthia C. Steiner, Marie-Ka Tilak, Emmanuel J. P. Douzery, François M. Catzeflis, Cynthia Steiner & Emmanuel J.P. Douzery
Phylogenetic relationships of 19 species of didelphid marsupials were studied using two nuclear markers, the non-coding transthyretin intron 1 (TTR) and the coding interphotoreceptor retinoid binding protein exon 1 (IRBP), and two mitochondrial genes, the protein-coding cytochrome b (cyt-b) and the structural 12S ribosomal DNA (12S rDNA). Evolutionary dynamics of these four markers were compared to each other, revealing the appropriate properties presented by TTR intron 1 together with its well supported and resolved phylogenetic...

Data from: Local molecular clocks in three nuclear genes: divergence times for rodents and other mammals and incompatibility among fossil calibrations.

Emmanuel J. P. Douzery, Frédéric Delsuc, Michael J. Stanhope & Dorothée Huchon
Reconstructing the chronology of mammalian evolution is a debated issue between molecule- and fossil-based inferences. A methodological limitation of molecules is the evolutionary rate variation among lineages, precluding the application of the global molecular clock. We considered 2422 first and second codon positions of the combined ADRA2B, IRBP, and vWF nuclear genes for a well-documented set of placentals including an extensive sampling of rodents. Using seven independent calibration points and a maximum-likelihood framework, we evaluated...

Data from: Ecomorphological diversification among South American spiny rats (Rodentia, Echimyidae): a phylogenetic and chronological approach.

Thomas Galewski, Jean-François Mauffrey, Yuri L. R. Leite, James L. Patton, Emmanuel J. P. Douzery, Thomas Galewski, Jean-François Mauffrey, Yuri L. R. Leite, James L. Patton, Emmanuel J. P. Douzery & Emmanuel J.P. Douzery
The phylogeny of South American spiny rats (Rodentia; Echimyidae) was studied using the exon 28 of the von Willebrand Factor nuclear gene (vWF). Sequences were analysed separately and in combination with a mitochondrial dataset (cyt b, 12S and 16S rRNAs) used in previous publications. The basal polytomy of echimyids was partially resolved and unexpected intergeneric clades were recovered. Thus, the intimate nested position of Myocastor within echimyids is evidenced. A well-supported clade is identified, including...

Data from: Molecular phylogenetics unveils the ancient evolutionary origins of the enigmatic fairy armadillos

Frédéric Delsuc, Mariella Superina, Marie-Ka Tilak-Jean, Emmanuel J. P. Douzery, Alexandre Hassanin, Marie-Ka Tilak & Emmanuel J.P. Douzery
Fairy armadillos or pichiciegos (Xenarthra, Dasypodidae) are among the most elusive mammals. Due to their subterranean and nocturnal lifestyle, their basic biology and evolutionary history remain virtually unknown. Two distinct species with allopatric distributions are recognized: Chlamyphorus truncatus is restricted to central Argentina, while Calyptophractus retusus occurs in the Gran Chaco of Argentina, Paraguay, and Bolivia. To test their monophyly and resolve their phylogenetic affinities within armadillos, we obtained sequence data from modern and museum...
