Learn more about the Andean hairy armadillo – with amazing Andean hairy armadillo photos and facts on Arkive. A recent work shows that Chaetophractus nationi and C. vellerosus would be the same species, and thus its distribution would extend further to. Familia: Chlamyphoridae Subfamilia: Euphractinae Genus: Chaetophractus Species: Chaetophractus nationi.

The genus Chaetophractus is described as comprising 3 species of hairy armadillos Wetzel ab ; Wetzel et al. The only differences are in statistical support values, which slightly increased for joining E. We defined cranial landmarks 45 taken on each side and 10 on the midline; Fig.

In fact, only a single mitochondrial haplotype was detected among chaetopyractus 10 D-loop sequences obtained for C. The morphological analyses were carried out in a morphogeometric framework Dryden and Mardia This large variation ultimately precludes the use of the cephalic shield width as a diagnostic character.

The contents of all supporting data are the sole responsibility of the authors. The Andean hairy armadillo lives exclusively in open high-altitude grasslands 2. Share on Facebook Tweet Send email. Assessing space chaetopractus in meadow voles: One clear example is the 5 euphractine armadillos: Euphractus sexcinctus Linnaeus,Zaedyus pichiy Desmarest,and 3 species of Chaetophractuswhich over time have been considered a subfamily called Euphractinae Frechkop and Yepesrecognized as a tribe Euphractini— Cabreralumped into a single genus Euphractus — Moellerand reclassified as a tribe by Wetzel b.


Following Poljakwho previously conducted phylogeographic studies of C. This approach is equivalent to a hold-out sample cross-validation Hair et al.

Chaetophractus nationi

The patterns of shape change were evaluated in relation to the taxonomy, which allowed defining morphospaces. Size variation with box and whisker plot showing median, quartile, and range in: A recent publication of Pacheco also locates the species in Perubasically in Puno Region. Help us improve the site by taking our survey.

Within Euphractinae, the maximum likelihood topology obtained from the concatenation was fully congruent with the phylogeny obtained from the most informative non-coding partition in natiomi the paraphyly of the chaetophractks Chaetophractus Fig. Help us share the wonders of the natural world. This absence of genetic diversity observed in the 10 individuals sampled at the scale of the Oruro region suggests a local reduction of effective population size.

Phylogenetic relationships of armadillo subfamilies Dasypodinae, Tolypeutinae, Chlamyphorinae, and Euphractinae represented as maximum likelihood phylograms inferred from the concatenation of a the 6 nuclear non-coding markers; b the 2 nuclear protein-coding genes BRCA1 and VWF; and c all 8 non-coding and protein-coding nuclear markers.

We used qualitative and quantitative approaches to evaluate the morphological differences between species. The grouping of these 2 genera to the exclusion of Zaedyus would be congruent with the cladistic study of craniodental characters by Gaudin and Wible In addition, this species is also persecuted for its disruptive burrowing on agricultural land 1.

The Morpho package in R allows 3-dimensional rendering to visualize the change in shape along the principal component of interest. The materials consist of data provided by the author that are published to benefit the reader. Semilandmarks are indicated in brackets.


The only significant nationo we identified between putative specimens of C. University of Chicago Press, Chicago. A dash – indicates that the node was not recovered in the corresponding analysis.

The molecular phylogenetic reconstructions led to apparent topological conflicts between non-coding and protein-coding nuclear markers. Ein beitrag zur phylogenie der Dasypodidae Bonaparte, This study assessed for the first time the taxonomic status of the Andean hairy armadillo, C. Quantitative analyses of form were carried out through classical and geometric morphometrics as described below. Multiple Alignment of Coding Sequences accounting for frameshifts and stop codons.

Ultraconserved elements are novel phylogenomic markers that resolve placental mammal phylogeny when combined with species-tree analysis. International Natilni for Conservation of Nature. Ecomorphology of vervet monkeys: Head and body length reaches to mm and the tail length is 90 to mm.

In this perspective, the targeted-sequence capture and sequencing of genomic regions flanking ultraconserved elements McCormack et al. These figures dropped to 55 variable 2.
