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.

ADW: Chaetophractus nationi: INFORMATION
Male Andean hairy amadillos only pair up with a female during mating season. One clear example is the 5 euphractine armadillos: These animals are well adapted for digging and foraging in the undergrowth and have short legs, long powerful claws, and pointed snouts 2.
The scale bar represents the mean number of substitutions per site.
The variation in shape associated with principal component axis 1 Descriptive chaetophravtus median, quartile, and range of width: Cercopithecinae inferred from geometric nstioni analysis of landmark data. The Andean hairy armadillo Chaetophractus nationi is an armadillo located in Boliviain the region of the Puna ; the departments of OruroLa Pazand Cochabamba Gardner, Journal of the Royal Statistical Society.
Finally, phylogenetic analyses of euphractine armadillos based on a combination of 6 non-coding nuclear markers and 2 nuclear exons suggest the paraphyly of the genus Chaetophractuswith C. Vargas CBF and A. 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 a smaller orbit Fig.
These data provide evidence for 4 distinct morphological entities within euphractine armadillos that correspond to each species assuming that C. Embryos within the mother still produce their own placenta.
Embed this Arkive thumbnail link “portlet” by copying and pasting the code below. Andean hairy armadillos are considered omnivore s because they eat a variety of foods. It is hoped that this measure will reduce trade in this species and therefore the extent to which it chaetophfactus hunted, although enforcement on trade in souvenirs is often inadequate 8. According to Hoodcentroid size is a geometric measure of size that follows the same mathematical behavior as body mass.
Synapomorphy of the Bilateria. Andean large hairy armadillo courtship involves the male following the female avidly, and mating occurs with the male mounting the female from behind. Ambiguously aligned sites were then filtered by using the program Gblocks Castresana with default relaxed parameters.
The genus Chaetophractus is described as comprising 3 species of hairy armadillos Wetzel ab ; Wetzel et al. Rodents of Unusual Size. From Wikipedia, the free encyclopedia. However, this topology received only moderate bootstrap support from maximum likelihood whereas the Bayesian approach resulted in an unresolved multifurcation within Euphractinae.
Chaetophractus nationi is nocturnal during the summer months to avoid the heat of the day and to maximize feeding time at night. As a consequence, small hairy armadillos are usually identified based on their relative size and capture site, with larger or more hairy individuals, as well as high-altitude specimens or those originating from western Bolivia, northern Chile and northwestern Argentina being assigned to C. Loughry, and 2 anonymous reviewers for useful comments.
A color ramp was incorporated to the mesh material to represent the strength of shape change from the consensus. This character was originally used by Wetzel b to discriminate among euphractine species.
The Andean hairy armadillo communicates with other armadillos through the use of chemicals, as well as through touch. While the nuchal crest displaces posteriorly, the foramen magnum does so anteriorly. How Armadillos can spread leprosy”.
Influence of Tertiary paleoenvironmental changes on the diversification of South American mammals: We thank the editor B.
The opposite tendency is shown on the positive side Fig. The 2nd set of samples comprised a total chaetopyractus skulls of adult euphractine species and was used to conduct the skull morphogeometric analyses. In the latitudinal and altitudinal analysis Fig.
