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.

There is, however, much overlap among the specimens from high and low altitudes independent of latitude. There is an apparent general pattern with specimens from the northern end of the distribution having higher median ratios than those from the southeastern end. This large variation ultimately precludes the use of the cephalic shield width as a diagnostic character. Identical sequences in C. This species is also thought to be present in northern Argentina.

For example, compare Catamarca —3, m asl in the north, to Buenos Aires 5— m aslSan Luis around m asland Mendoza —1, m asl in the south. Multivariate analyses of shape variation based on 3-dimensional landmark coordinates of skulls allowed a clear differentiation of each species with the exception of C. With the qualitative approach, we analyzed the variation of the squamosal-jugal suture to assess its specific diagnostic value.

The non-coding nuclear partition suggests the paraphyly of the genus Chaetophractus by grouping C.

The animals came from different localities of the department of Oruro in Bolivia; the zoo staff provided information on capture sites and dates. Cgaetophractus armadillo Dasypus novemcinctus. In addition, this species is also persecuted for its disruptive burrowing on agricultural land 1. Nevertheless, the reality of the subspecies definition within C.


Chaetophractus nationi

Embryos within the mother still produce their own placenta. The sequential Bonferroni correction Rice was used to address natiini problem of multiple statistical tests.

Wildscreen With – Tom Hooker: Receive exclusive offers and chaetopyractus from Oxford Academic. We assessed the phylogenetic relationships of hairy armadillos by collecting both mitochondrial and nuclear markers for all currently described species. The scale bar represents the mean number of substitutions per site.

Chaetophractus nationi – Wikispecies

In both groups, there are specimens with rounded or angular sutures. Nocturnal Active at night. These results demonstrate that C.

Project for City and Guilds: Landmark and semilandmarks 56— on the left side are not shown. Polymerase chain reaction conditions for the 2 protein-coding nuclear markers were: Once thought to be closely related to turtles because of their tough protective carapaceszoologists now classify them in the mammalian order Cingulata.

A Taxonomic and Geographic Reference 3rd ed. Nqtioni principal component axis 2, Z. This phylogenetic tree, rooted with Dasypodinae Dasypussupports the monophyly of the subfamilies Tolypeutinae PriodontesCabassousand Tolypeutesand Euphractinae EuphractusZaedyusand Chaetophractus in agreement with previous studies based on mitochondrial and nuclear markers Delsuc et al. The 2nd set of samples comprised a total of skulls of adult euphractine species and was used to conduct the skull morphogeometric analyses.

Over-fitting is avoided by predicting group affiliation using discriminant functions based on samples that do not include the specimens that are being chaetophracfus. The bony plates of armour that surround this animal’s body serve as protection from predators. The main shape change from small forms to larger ones involved a longer palate, short nasal length on the midline, larger frontal, lower height of the calvaria and occiput, broader muzzle, and mationi smaller orbit Fig.


ADW: Chaetophractus nationi: INFORMATION

There are currently 21 described species of armadillos Xenarthra, Cingulata, Dasypodidae— Gardner Synapomorphy of the Bilateria. Such a relationship fhaetophractus strongly supported by the phylogenetic analysis of more than 12kb of non-coding retroposon flanking sequences, and also by the shared presence of a specific DAS-III3b element insertion, plus a nucleotide diagnostic deletion in the An5 genomic locus.

Biological samples were collected from 10 Andean hairy armadillos putative C. It is hoped that this measure will reduce trade in this species and therefore the extent to which it is hunted, although enforcement on trade in souvenirs is often inadequate 8. Grzimek’s Chartophractus of Mammals Volume 2. The mean percentages of individuals classified by discriminant function analyses according to species are shown in Table 2 hold-out cross-validation. A dash – indicates that the node was not recovered in the corresponding analysis.
