Monitoring wolf populations using howling points combined with sign survey transects

open access: yes, 2005
Wolves respond to simulated howling, especially during the mating and breeding seasons. Simulated howling points are, therefore, commonly used by many wolf researchers around the world to estimate pack numbers in a given area.

A perspective from the Mesozoic: Evolutionary changes of the mammalian skull and their influence on feeding efficiency and high‐frequency hearing

open access: yesThe 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 relationship between form and function of the carnivore mandible

open access: yesThe Anatomical Record, EarlyView.
Abstract Dietary morphology diversified extensively in Carnivoraformes (living Carnivora and their stem relatives) during the Cenozoic (the last 66 million years) as they evolved to capture, handle, and process new animal and plant diets. We used 3D geometric morphometrics, mechanical advantage, and finite element analysis to test the evolutionary ...

Tooth row allometry in domestic rabbits and nondomestic lagomorphs: Evidence for a decoupling of body and tooth row size changes in evolutionary time

open access: yesThe Anatomical Record, EarlyView.
Domestic rabbits of different body sizes differ disproportionately in the length of their tooth row or the length of their diastema. Abstract In various domestic mammals, smaller breeds tend to have proportionally larger teeth, whereas this is not a universal trend across mammals.

Descriptive, comparative, and functional anatomy of the facial musculature in cattle (Bos taurus)

open access: yesThe 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.

Tracing the evolutionary history of the morpho‐anatomy of baculum in primates

open access: yesThe Anatomical Record, EarlyView.
Abstract Animal morphology reflects both evolutionary history and present‐day adaptation. Male mammal copulatory structures such as the baculum (penile bone) are ideal for studying these processes because of their complexity and high interspecific variability. In primates, however, research has focused mostly on baculum length.

Born this way: Does variation in perinatal limb bone morphology predict adult locomotor repertoire in primates?

open access: yesThe Anatomical Record, EarlyView.
Abstract Primates show a high degree of locomotor diversity that engenders similar variance in limb bone cross‐sectional geometry and bending strength: leaping primates have stronger hindlimb bones whereas suspensory species have stronger forelimb bones.

Estimating denning date of wolves with daily movement and GPS location fix failure

open access: yesWildlife Society Bulletin, 2016
We used Global Positioning System (GPS) radiotelemetry data from 7 breeding female wolves (Canis lupus; n = 14 dennings) in 3 regions across Alaska, USA, during 2008–2011 to develop and compare methods for estimating the onset of denning, and thus infer ...

Periportal and Puncture Capsulotomy Techniques Have Similar Outcomes to Traditional Capsulotomies With Closure in Hip Arthroscopy: A Systematic Review and Meta‐analysis of 2‐Year Outcomes

open access: yesArthroscopy, EarlyView.
Purpose To systematically evaluate capsulotomy techniques through patient‐reported outcome measures, rates of revision arthroscopy, conversion to total hip arthroplasty, and achievement of clinically meaningful outcomes. Methods PubMed, Scopus, and Embase databases were queried in June 2024 for studies that could be used to compare capsular management ...

Breast cancer among shift workers: results of the WOLF longitudinal cohort study

open access: yesScandinavian Journal of Work, Environment & Health, 2013
OBJECTIVE: The aim of this study was to investigate whether shift work (with or without night work) is associated with increased risk of breast cancer. METHODS: The population consisted of 4036 women.
