Quantitative assessment of masticatory muscles based on skull muscle attachment areas in Carnivora
The Anatomical Record, EarlyView.Abstract Masticatory muscles are composed of the temporalis, masseter, and pterygoid muscles in mammals. Each muscle has a different origin on the skull and insertion on the mandible; thus, all masticatory muscles contract in different directions. Collecting in vivo data and directly measuring the masticatory muscles anatomically in various Carnivora ...

Bird Beak Accuracy Assessment [PDF]
, 2003 The purpose of this resource is to quantitatively evaluate the accuracy of a classification system. Students sort birds into three possible classes based on each bird's beak: carnivores, herbivores, and omnivores.

The 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.

Long‐Term Changes in Survival of Eurasian Lynx in Three Reintroduced Populations in Switzerland
Ecology and EvolutionFor conservation or management programs, basic data on vital rates are important but often hard to acquire for long‐lived and elusive wildlife species such as large carnivores.

Fencing affects movement patterns of two large carnivores in Southern Africa
Frontiers in Ecology and Evolution, 2023 The erection of peripheral fences around protected areas has been shown to adversely affect the movement behavior, genetic connectivity and long-term viability of animal populations. However, fencing is also used extensively to reduce human encroachment,

Top carnivore decline has cascading effects on scavengers and carrion persistence
Proceedings of the Royal Society B, 2018 Top carnivores have suffered widespread global declines, with well-documented effects on mesopredators and herbivores. We know less about how carnivores affect ecosystems through scavenging.

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 ...

First rangewide density estimate of the endemic and isolated Luangwa giraffe in Zambia
Scientific ReportsThe Luangwa giraffe (Giraffa tippelskirchi thornicrofti), a subspecies of the Masai giraffe endemic to the Luangwa Valley of northeastern Zambia, inhabits an increasingly human-modified landscape. Accurate and current population estimates are critical to

Body condition and dosage effects on ketamine–xylazine immobilization of female white‐tailed deer
Wildlife Society Bulletin, 2013 Ketamine and xylazine are an effective chemical combination for white‐tailed deer (Odocoileus virginianus) immobilization, but the effects of body condition on ketamine–xylazine efficacy have not been examined.

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 ...
