Variability of jaw muscles in Tunisian street dogs and adaptation to skull shape

open access: yesThe Anatomical Record, EarlyView.
Abstract The impact of artificial selection on the masticatory apparatus of dogs has been poorly studied, and comparative data with dogs subjected to more natural constraints are lacking. This study explores the jaw musculature of Tunisian street dogs, which are largely free from the influence of breed‐specific selection.

The morphology of the oval window in Paranthropus robustus compared to humans and other modern primates

open access: yesThe Anatomical Record, EarlyView.
Abstract The oval window (OW) is an opening connecting the inner and middle ear. Its area has been shown to consistently scale with body mass (BM) in primates, and has been used alongside semi‐circular canal (SCC) size to differentiate Homo sapiens and fossil hominins, including Paranthropus robustus.

“Visiting scientist effect”? Exploring the impact of time‐lags in the digitization of 2D landmark data

open access: yesThe Anatomical Record, EarlyView.
Abstract Measurement error (ME) in geometric morphometrics has been the subject of countless articles, but none specific to the effect of time lags on landmark digitization error. Yet, especially for visiting scientists working on museum collections, it is not uncommon to collect data in multiple rounds, with interruptions of weeks or years. To explore

Topological and variational modularity: A case study using the pectoral girdle across the Chrosomus eos‐neogaeus hybridization complex

open access: yesThe Anatomical Record, EarlyView.
Abstract Modularity and integration are key developmental properties and have remained central in evo‐devo research because of how they relate to evolvability. While modularity and integration have commonly been assessed with landmark‐based geometric morphometrics (GMM), other methods such as anatomical network analysis (AnNA) are increasingly being ...

Variation in parrot jaw musculature

open access: yesThe Anatomical Record, EarlyView.
Interspecific morphological differences in some superficial jaw muscles of parrots. Abstract Psittaciformes, the order encompassing parrots and their relatives, are highly diverse and generally known for having a strong beaks used for multiple behaviors. The muscles related to the masticatory apparatus should reflect this functional complexity; however,
