A comparative morphological study of the ligamentum lamina nuchae and ligamenta interspinalia reveals enthesis patterns at the sites of attachment from the second to seventh cervical vertebrae in four extant species of Equus

Vertebrate Anatomy, Morphology, Palaeontology, 2020
Morphological variation in the attachment sites of the ligamentum lamina nuchae and ligamenta interspinalia to the 2nd to 7th cervical vertebrae is described in four species of Equus, and enthesis patterns in relation to these attachment sites are ...

Comparative functional morphological study of the tarsal joint mobility in artiodactyls and perissodactyls in light of astragalar morphological differences

Journal of Anatomy, EarlyView.
This study investigated how variations in the shape of the astragalus affect tarsal joint behavior, using CT scans. In artiodactyls with a double‐pulley astragalus, the calcaneus shifted plantarly during plantarflexion. This suggests the movement increases hindlimb functional length and contributes to enhanced running speed.

Brazilian donkeys (Equus asinus) have a low exposure to Neospora spp.

Revista Brasileira de Parasitologia Veterinária
Donkeys (Equus asinus) are closely related to horses and are known to be infected by several equine pathogens. Neospora caninum and Neospora hughesi are protozoan parasites that infect horses, but they were not confirmed in donkeys up to this date.

Unveiling Novel Viral Diversity, Biogeography, and Host Networks in Wildlife Through High‐Throughput Sequencing Data Mining

Advanced Science, Volume 12, Issue 46, December 11, 2025.
Analysis of 57 536 high‐throughput sequencing datasets uncovers a vast, hidden world of viruses in wildlife. The researchers reveal significant geographic and host‐specific patterns of viruses, and their surprising cross‐species transmissions, such as avian flu viruses infecting goats.

Plesippus francescana (Frick) from the late Pliocene, Coso Mountains, California, with a review of the genus Plesippus [PDF]

, 1936
Two mammalian types, occurring in a late Pliocene fauna from the Coso Mountains, California, have already been described. Among the more abundant forms in this assemblage are the horses of the genus Plesippus.

Observations of tear‐drinking by lepidopterans on moose (Alces americanus americanus) in northeastern North America

Ecosphere, Volume 16, Issue 11, November 2025.
Abstract Lepidoptera have long been known to feed on the tears of vertebrates as a presumed source of minerals or nutrients. While this unusual behavior has been observed in a variety of species, only a single previous record has been documented outside of the tropics. Here, we present the first documentation of moths visiting the eyes of a bull moose (

Why the Donkey Did Not Go South: Disease as a Constraint on the Spread of Equus asinus into Southern Africa [PDF]

, 2017
Donkeys are the only ungulate definitely known to have been domesticated in Africa and were widely employed in the north of the continent and through the Sahara and the Sahel as pack animals, as well as spreading through much of the Old World.
