Altitudinal range extension of the nine-banded armadillo, Dasypus novemcinctus (Linnaeus, 1758) (Mammalia, Xenarthra), in Irazú Volcano National Park, Costa Rica

Xenarthra
The nine-banded armadillo (Dasypus novemcinctus) is a widely distributed species throughout North and South America, however its distribution has been restricted by latitude and altitude due to cold temperatures.

Space use by giant anteaters (Myrmecophaga tridactyla) in a protected area within human‐modified landscape

Ecology and Evolution, 2020
Spatial ecology data are essential for conservation purposes, especially when extinction risk is influenced by anthropogenic actions. Space use can reveal how individuals use the habitat, how they organize in space, and which components are key resources

New mammalian and avian records from the late Eocene La Meseta and Submeseta formations of Seymour Island, Antarctica [PDF]

PeerJ, 2020
The middle–late Eocene of Antarctica was characterized by dramatic change as the continent became isolated from the other southern landmasses and the Antarctic Circumpolar Current formed.

Unravelling the phylogeny of armadillos and their kin (Mammalia, Xenarthra, Cingulata) combining morphological, molecular, and stratigraphic data

Cladistics, EarlyView.
Abstract Cingulata, a major lineage of Xenarthra, comprises extinct and extant armoured placental mammals that diversified throughout the Cenozoic. Despite extensive study, phylogenetic hypotheses based on morphological and molecular data remain incongruent, and no total evidence analysis has been conducted. Here, we integrate the largest morphological

Hoffmann's two‐toed sloth II: Muscle architectural properties in the thoracic limb of Choloepus (Pilosa: Xenarthra)

Journal of Anatomy, EarlyView.
Two‐toed sloths use their thoracic limbs for more frequent and greater suspensory support than three‐toed sloths and have muscle architectural properties consistent with stability of the pectoral girdle, enhanced flexor force/torque applied at the shoulder and elbow joints, and grip on the support as indicated by their myology. Abstract Two‐toed sloths

Early history of mammals is elucidated with the ENCODE multiple species sequencing data. [PDF]

PLoS Genetics, 2007
Understanding the early evolution of placental mammals is one of the most challenging issues in mammalian phylogeny. Here, we addressed this question by using the sequence data of the ENCODE consortium, which include 1% of mammalian genomes in 18 species
