Digital range of motion analysis is sensitive to subjective steps in joint model construction

open access: yesJournal of Anatomy, EarlyView.
A systematic sensitivity analysis of a six degree‐of‐freedom range of motion (ROM) analysis workflow was conducted to evaluate how variation in the subjective steps of the reference pose assembly affects the determined viable poses in the ankle and tarsometatarsophalangeal III joints of Guinea fowl (Numida meleagris).

A description of dental microanatomy and implantation geometry in Chamaeleonidae

open access: yesJournal of Anatomy, EarlyView.
A reassessment of the dental histology in adult chamaeleons reveals the presence of periodontal ligament. Alongside alveolar bone and cementum, these tissues together constitute a compacted and remodelled tripartite periodontium. Our findings include the novel observation of plicidentine‐like protuberances of dentine within underlying bone.

Syrinx anatomy and vocalizations in New World vultures (Aves: Cathartidae): Implications for avian vocal evolution

open access: yesJournal of Anatomy, EarlyView.
New World vultures are the only avian clade proposed to lack a syrinx and have been described as non‐vocal. Using dissection, diceCT, and histology, we demonstrate that cathartid vultures have novel syringeal features that form a syrinx and vocal characterization reveals that they produce more complex vocalizations than previously reported.
