A suture in time: The ontogeny of cranial suture morphology in mammals

open access: yesJournal of Anatomy, EarlyView.
Mammal cranial sutures are important indicators of the biomechanical and developmental pressures acting upon the skull. Across three prominent sutures dividing the vault of the mammalian skull, divergent patterns emerge both taxonomically and developmentally.

Fit for purpose? Analysis of the relationship between skull, beak shape and feeding ecology in Psittaciformes

open access: yesJournal of Anatomy, EarlyView.
Psittaciformes exhibit high levels of morphological diversity, particularly in skull and beak structure, previously linked to diet and body size. Although there were some levels of significance between diet and beak shape, body mass was a much stronger co‐variate. Diet is not determining beak shape within the clade.

The raphe nuclear organization and serotonergic system in the bat (Artibeus planirostris)

open access: yesJournal of Anatomy, EarlyView.
Schematic representation of the methodological workflow used to characterize the serotonergic (5‐HT) system in the bat Artibeus planirostris. Serotonin (5‐HT) immunohistochemistry was performed on brainstem sections to identify and map the distribution of serotonergic neurons within the raphe nuclei.

Vicariant speciation resulting from biogeographic barriers in the Australian tropics: The case of the red‐cheeked dunnart (Sminthopsis virginiae)

open access: yesEcology and Evolution
Global biodiversity loss continues unabated, and in Australia, the rate of recent mammal extinctions is among the worst in the world. Meanwhile, the diversity among and within many endemic mammal species remains undescribed.

The Keystone‐Pathogen Hypothesis Updated: The Role of Porphyromonas gingivalis in Periodontitis

open access: yesJournal of Periodontal Research, EarlyView.
Porphyromonas gingivalis orchestrates a coordinated manipulation of immune and inflammatory responses in periodontal tissues which leads to the generation of a dysbiotic, subgingival biofilm community, and progression of periodontitis. The type 9 secretion system, lipid A modification, and the formation of outer membrane vesicles are important ...

Evaluation of the rate of residual polystomatic sublingual acinar tissue without tunneling dorsal to the digastricus using a ventral or ventrolateral approach in cats

open access: yesVeterinary Surgery, EarlyView.
Abstract Objective To evaluate the rate of residual polystomatic sublingual acinar tissue if tunneling dorsal to the digastricus muscle and dissection to the sublingual caruncle is not performed during mandibular‐sublingual sialadenectomy in cats. Study design Cadaveric study. Sample population A total of 10 feline cadavers.
