Small fish, large variation: Morphological diversity of Weberian apparatus in Noturus catfishes and ecological implications

open access: yesThe Anatomical Record, EarlyView.
Abstract The Weberian apparatus is a hearing specialization unique to the otophysan fishes, and an unexpected degree of morphological variation exists in species of the Noturus catfishes. Our aim in this study is to investigate relationships between morphological variations and ecology that may drive this variation.

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.

Morphology and function of pinniped necks: The long and short of it

open access: yesThe Anatomical Record, EarlyView.
Abstract Terrestrial vertebrates from at least 30 distinct lineages in both extinct and extant clades have returned to aquatic environments. With these transitions came numerous morphological adaptations to accommodate life in water. Relatively little attention has been paid to the cervical region when tracking this transition.
