Molecular and morphological baraminology of Xenarthra

, 2023
There are 31 xenarthran species living today, made up of armadillos, anteaters, and sloths. These animals are characterized by a narrow, elongated skull and a unique vertebral process in the posterior trunk. Xenarthra represents an apobaramin within which several holobaramins may be discerned, using both mitochondrial DNA and morphological data.

Risk posed by the HPAI virus H5N1, Eurasian lineage goose/Guangdong clade 2.3.4.4b. genotype B3.13, currently circulating in the US

EFSA Journal, Volume 23, Issue 7, July 2025.
Abstract The emergence of highly pathogenic avian influenza (HPAI) A(H5N1), clade 2.3.4.4b, genotype B3.13 in U.S. dairy cattle marks a significant shift in the virus' host range and epidemiological profile. Infected cattle typically exhibit mild clinical signs, such as reduced milk production, mastitis and fever, with morbidity generally below 20% and

Bilateral pre-axial polydactyly in a wild juvenile Hoffmann’s two-toed sloth (Choloepus hoffmanni)

Xenarthra
Polydactyly is a relatively common congenital condition in humans, also described in some other species of animals, where more digits than usual are present in the hands or feet. The literature about congenital anomalies in sloths is sparse.

Additions to the knowledge of Urumaquia robusta (Xenarthra, Phyllophaga, Megatheriidae) from the Urumaco Formation (Late Miocene), Estado Falcön, Venezuela [PDF]

, 2018
We describe new remains ofUrumaquia robusta Carlini, Brandoni & Sänchez, 2006, which significantly improve the knowledge of the species and allow a more precise discussion about the relationships with the rest of the South American Megatheriinae. The new

First record of Mylodon Darwini Owen (xenarthra, tardigrada, mylodontidae) from Arroyo Feliciano formation (late pleistocene), Entre Rios, Argentina [PDF]

, 2015
In this contribution a new record of M. darwini Owen, based on an incomplete skull (MRHU-1) recovered from the Arroyo Feliciano Formation (late Pleistocene) on the Gualeguay River cliffs, nearly the city of Urdinarrain, is presented.

Three‐Dimensional Limb Kinematics in Brown‐Throated Three‐Toed Sloths (Bradypus variegatus) During Suspensory Quadrupedal Locomotion

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, Volume 343, Issue 5, Page 564-577, June 2025.
ABSTRACT Suspensory locomotion differs significantly from upright quadrupedal locomotion in mammals. Nevertheless, we know little concerning joint kinematics of suspensory movement. Here, we report three‐dimensional kinematic data during locomotion in brown‐throated three‐toed sloths (Bradypus variegatus). Individuals were recorded with four calibrated

Core promoter short tandem repeats as evolutionary switch codes for primate speciation [PDF]

, 2015
Alteration in gene expression levels underlies many of the phenotypic differences across species. Because of their highly mutable nature, proximity to the +1 transcription start site (TSS), and the emerging evidence of functional impact on gene ...

A Composite Genome Approach to Identify Phylogenetically Informative Data from Next-Generation Sequencing

, 2014
We have developed a novel method to rapidly obtain homologous genomic data for phylogenetics directly from next-generation sequencing reads without the use of a reference genome.

The Initial Opening of the Drake Passage Occurred During ca. 62‐59 Ma

Geophysical Research Letters, Volume 52, Issue 7, 16 April 2025.
Abstract Although the Drake Passage has been considered a critical component of ocean circulation and climate, its initial opening age remains controversial due to the weak constraints on the paleoposition of the Antarctic Peninsula. Here, new zircon U‐Pb geochronological studies are conducted on the Barchans Islands, providing a critical age ...
