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

open access: yesThe 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)

open access: yesXenarthra
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

open access: yesEFSA 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

open access: yesConservation Genetics Resources, 2020
Although sex assignment is essential to study biology and ecology of an animal, in Xenarthra there is still no standardized assay for genetic sex identification. Here, we evaluate the potential of two nuclear fragments [Zinc finger (~ 400 bp) and Sex-determination region Y (~ 180 bp) genes] for sex identification of seven Xenarthra species.
