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

Foraging under Predation Risk: A test of giving-up densities with samango monkeys in South Africa [PDF]
, 2013 Animals frequently make a trade-off between food and safety and will sacrifice feeding effort if it means safety from predators. A forager can also vary its vigilance levels to manage predation risk.

The Anatomical Record, EarlyView.Abstract The complex evolutionary history behind modern mammalian chewing performance and hearing function is a result of several changes in the entire skeletomuscular system of the skull and lower jaw. Lately, exciting multifunctional 3D analytical methods and kinematic simulations of feeding functions in both modern and fossil mammals and their ...

The Anatomical Record, EarlyView.We describe the functional anatomy of masticatory muscles in nine opossums, finding a generalized anatomical pattern with differences related to skull morphology. Variation in quantitative myological data and estimated bite force was mostly related to size, and the increase in bite force supports dietary diversification associated with size increase ...

The Anatomical Record, EarlyView.Abstract Actinopterygii is a major extant vertebrate group, but limited data are available for its earliest members. Here we investigate the morphology of Devonian actinopterygians, focusing on the lower jaw. We use X‐ray computed tomography (XCT) to provide comprehensive descriptions of the mandibles of 19 species, which span the whole of the Devonian

Commentary: What's so interesting about sabertooths?
The Anatomical Record, EarlyView.Abstract Sabertooth creatures are fascinating to the public and to scientists. This Special Issue on The Anatomy of Sabertooths starts with a discussion of what exactly a sabertooth is, continues with a couple of papers about other animals with extraordinarily long teeth, and then delves into analyses of fossil sabertoothed taxa—some of which are not ...
