Updating the forelimb anatomy of the domestic cat (Felis catus, Felidae) based on evolutionary inferences of its muscles and nerves I: Shoulder and brachium

open access: yesJournal of Anatomy, EarlyView.
In this study, we provide a detailed description of the shoulder and brachium muscles and the brachial plexus of the domestic cat (Felis catus). We identified muscular variants (articularis humeri, coracobrachialis longus, biceps brachii caput breve), clarified the independence of the anconeus medialis muscle from the triceps brachii muscle, and ...

First molecular detection and characterization of herpesvirus and poxvirus in a Pacific walrus (Odobenus rosmarus divergens) [PDF]

open access: yes, 2014
BACKGROUND Herpesvirus and poxvirus can infect a wide range of species: herpesvirus genetic material has been detected and amplified in five species of the superfamily Pinnipedia; poxvirus genetic material, in eight species of Pinnipedia.

Fossils and living taxa agree on patterns of body mass evolution:A case study with Afrotheria [PDF]

open access: yes, 2015
Most of life is extinct, so incorporating some fossil evidence into analyses of macroevolution is typically seen as necessary to understand the diversification of life and patterns of morphological evolution.

Rodent monocyte‐derived macrophages do not express CD163: Comparative analysis using macrophages from living boreoeutherians

open access: yesDevelopmental Dynamics, Volume 255, Issue 4, Page 372-402, April 2026.
Abstract Background CD163 is a scavenger receptor predominantly expressed on the surfaces of macrophages in various mammalian species and is a marker of anti‐inflammatory (M2‐like) macrophages. High density of CD163‐positive tumor‐associated macrophages (TAMs) is associated with worse prognosis in various patient tumors.

Analyses of Sweet Receptor Gene (Tas1r2) and Preference for Sweet Stimuli in Species of Carnivora [PDF]

open access: yes, 2017
The extent to which taste receptor specificity correlates with, or even predicts, diet choice is not known. We recently reported that the insensitivity to sweeteners shown by species of Felidae can be explained by their lacking of a functional Tas1r2 ...

Morphological diversity of saber‐tooth upper canines and its functional implications

open access: yesThe Anatomical Record, Volume 308, Issue 11, Page 3007-3021, November 2025.
Abstract Elongated upper canine teeth, commonly known as saber‐teeth, have evolved three times within the sub‐order Feliformia. The species that wielded them flourished throughout the Cenozoic and have historically been separated into two morphological groups: the dirk‐tooths with longer, flatter canines, and the scimitar‐tooths with shorter, serrated ...

Exposed weapons: A revised reconstruction of the facial anatomy and life appearance of the saber‐toothed cat Megantereon (Felidae, Machairodontinae)

open access: yesThe Anatomical Record, Volume 308, Issue 11, Page 2924-2943, November 2025.
Abstract Megantereon was a widespread saber‐toothed felid from the Pliocene and Pleistocene of the Old World and North America, but its rarity in the fossil record makes it complicated to restore its life appearance. Lack of complete specimens makes it necessary to combine information from fossils of different individuals to reconstruct their facial ...

Resolution among major placental mammal interordinal relationships with genome data imply that speciation influenced their earliest radiations [PDF]

open access: yes, 2010
Background: A number of the deeper divergences in the placental mammal tree are still inconclusively resolved despite extensive phylogenomic analyses.

Anatomy of the “false thumb” of Tremarctos ornatus (Carnivora, Ursidae, Tremarctinae) : phylogenetic and functional implications [PDF]

open access: yes, 2006
Se describe por primera vez el sesamoideo radial o “falso pulgar” del oso de anteojos (Tremarctos ornatus), mostrando la gran similitud morfológica con el del panda gigante (Ailuropoda melanoleuca) y las diferencias que presenta con el resto de los ...
