Broadening the semiaquatic scene: Quantification of long bone microanatomy across pinnipeds
The Anatomical Record, EarlyView.Abstract Investigations of bone microanatomy are commonly used to explore lifestyle strategies in vertebrates. While distinct microanatomical limb bone features have been established for exclusively aquatic and terrestrial lifestyles, identifying clear patterns for the semiaquatic lifestyle remains more challenging.

Dynamic ecological system measures
Results in Applied Mathematics, 2019 The system decomposition theory has recently been developed for the dynamic analysis of nonlinear compartmental systems. The application of this theory to the ecosystem analysis has also been introduced in a separate article.

Gonadal development in scorpion mud‐turtles, Kinosternon scorpioides, in a controlled environment
The Anatomical Record, EarlyView.Stage 20 was identified as the critical point for gonadal differentiation in Kinosternon scorpioides, providing key insights into sex determination. These findings enhance conservation strategies by supporting reproductive management and population viability in both in situ and ex situ programs. Abstract Research on gonadal development including sexual

Predation of eggs and incubating females in willow ptarmigan Lagopus l. lagopus
Fauna NorvegicaNest predation is a major cause of reproductive loss in many ground-nesting birds. During 15 consecutive years the predation of nests and females throughout the incubation season were recorded in a willow ptarmigan Lagopus l.

An osteohistological analysis of Triceratops (Ornithischia: Ceratopsidae) cranial ornamentation
The Anatomical Record, EarlyView.Abstract Ceratopsids are among the most distinctive and well known extinct Cretaceous vertebrates, yet many details regarding the growth and composition of their cranial features are still not fully anatomically described or understood. In particular, striking cranial adornments such as the postorbital horns and parietal‐squamosal frill of Triceratops ...

Descriptive, comparative, and functional anatomy of the facial musculature in cattle (Bos taurus)
The Anatomical Record, EarlyView.Abstract Facial expressions can provide insight into animal emotions and pain, but no standardized system for assessing the entire facial display in cattle (Bos taurus Linnaeus) exists. The Facial Action Coding System (FACS), originally developed for humans, identifies distinct facial movements based on mimetic muscles.

The Anatomical Record, EarlyView.Abstract Tyrannosaurus is viewed as a model organism in vertebrate paleontology, with numerous studies analyzing its feeding biomechanics. Nonetheless, the evolution of this feeding performance has been under‐addressed in Tyrannosauroidea, especially in basal tyrannosauroids. Here we used muscle‐force reconstruction and finite element analysis (FEA) to
