Craniogenetic studies in Sus scrofa: With emphasis on the ‘orbitosphenoid’ problem

The Anatomical Record, Volume 308, Issue 7, Page 1931-1943, July 2025.
Abstract The orbitosphenoid is a skeletal element of the endocranium of extant mammals. However, it has also been described in many of their fossil ancestors. Craniogenetic studies show that it is composed of two types of bone: first, the cartilaginous ala orbitalis and parts of the trabecular plate are transformed by endochondral ossification; second,

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.

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

Molecular sexing of Xenarthra: A tool for genetic and ecological studies

Conservation Genetics Resources, 2020
Although sex assignment is essential to study biology and ecology of a given animal, in Xenarthra there is still no standardized assay for gender genetic identification. Here, we evaluate the potential of two nuclear fragments [SRY (~180pb) and Zinc finger (~400pb) genes] for sex identification of specimens who have lost their morphological ...

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

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 ...
