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.

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. The subsequent concatenation of the 5 non-coding data sets yielded an alignment totaling 2, nucleotide sites for 11 taxa.
The Supporting Information documents are linked to this manuscript and are available at Journal of Mammalogy online bationi. It also suggests the occurrence of a rapid diversification event, possibly related to paleoenvironmental changes Delsuc et al. Their territories are about eight acres in size. These markers were chosen in order to maximize nucleotide variability among the available sequences for euphractine armadillos: Furthermore, despite additional protection by national laws prohibiting the capture and trade of the Andean hairy armadillo in Bolivia, demand for armadillo products continues.
Nonetheless, several taxonomic natiobi and phylogenetic relationships within this subfamily still need to be elucidated.
Actually, several populations show large variation, independently of the number of specimens or diversity of environments represented in the sample. Cercopithecinae inferred from geometric morphometric analysis of landmark data. Loughry, and 2 anonymous reviewers for useful comments. A scanned surface of a putative C. In this chaetopjractus, we first present the results of the morphometric analyses aiming at revealing the morphological differentiation among hairy armadillo species in terms of both size and shape.
Valverde for strategic assistance on administrative issues and to N. Further resolution of the relationships within Euphractinae will thus involve gathering large-scale comparative genomic data, coupled with the use of gene tree-species tree reconstruction methods based on multispecies coalescent models Liu et al. The mean percentages of individuals classified by discriminant function analysis based on half cranium using shape coordinates, according to localities are shown in Table 3 hold-out cross-validation.
IUCN Red List of Threatened Species
Barn swallow Hirundo rustica. Based on these data, we propose that C.
In addition, the natilni divergence between them based on non-coding regions flanking retroposon elements was extremely low, with no difference detected in 3 out of the 5 markers investigated. Synapomorphy of the Bilateria.

A dash – indicates that the node was not recovered in the corresponding analysis. Among these, only the specimens from La Paz would potentially include C. These samples were taken before the morning meal in order to prevent any possible contamination in the subsequent DNA extractions.
Chile, Argentina, Uruguay, Paraguay.
Maximum likelihood bootstrap values BP ML were computed by using 1, pseudo-replicates of the same maximum likelihood heuristic search. The regrouping of E. The morphological analyses were carried out in a morphogeometric framework Dryden and Mardia These armadillos have even been found to eat rotting flesh and the maggots found within the corpse.
Geometric morphometric approaches to the study of sexual size dimorphism in mammals.
It is the largest species of Euphractinae and can be distinguished from the other members chaetophractue this tribe by its pale yellow or tan carapace and the absence of a movable band at the anterior margin of the scapular shield Redford and Wetzel Influence of Tertiary paleoenvironmental changes on the chateophractus of South American mammals: The Andean hairy armadillo’s sleep schedule depend on the season and temperature of its habitat.
Team WILD, an elite squadron of science superheroes, needs your help! Southern three-banded armadillo T. Cranial allometry, phylogeography, and systematics of large-bodied Papionins Primates: Please donate to Arkive Help us share the wonders of the natural world.
Wildscreen With – Tom Hooker: Calyptophractus Greater fairy armadillo C. The armouring extends to the top of the head, which bears dark plates like a helmet, and to the thin tail.
