Patterns of spinal motion, kinematic spaces and the land‐to‐sea transition in carnivorans

open access: yesThe Anatomical Record, EarlyView.
Using 3D reconstructions, we quantify intervertebral joint mobility to investigate how cervical, thoracic, and lumbar vertebral regions evolved distinct kinematic roles in pinnipeds. The findings reveal lineage‐specific adaptations for swimming and highlight the functional significance of vertebral joint flexibility in ecological transitions.

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.

Integrating Values and Ethics into Wildlife Policy and Management—Lessons from North America

open access: yesAnimals, 2011
Few animals provoke as wide a range of emotions as wolves. Some see wolves as icons of a lost wilderness; others see them as intruders. As the battle continues between wolf proponents and opponents, finding solutions that resolve conflicts while ...

Comparative cranial biomechanics reveal macroevolutionary trends in theropod dinosaurs, with emphasis on Tyrannosauroidea

open access: yesThe 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

How People Should Respond When Encountering a Large Carnivore: Opinions of Wildlife Professionals

open access: yesHuman-Wildlife Interactions, 2017
We conducted telephone surveys of wildlife professionals who work with large carnivores to ask their opinions about how people should respond to avoid being injured when confronted by a black bear (Ursus americana), grizzly bear (Ursus arctos), mountain ...

Valuation of Large Carnivores and Regulated Carnivore Hunting

open access: yesJournal of Forest Economics, 2020
Large carnivores are keystone species but represent economic costs to hunters. In Sweden, carnivore territories generally overlap with hunting areas, and as a result, conflicts occur because of the competition for prey. The wolf, lynx, and brown bear are protected species by law but are hunted when authorities allocate license hunting quotas.

Comparative Meta‐Analysis of Antimicrobial Peptides in Aquatic and Terrestrial Livestock Species

open access: yesAnimal Research and One Health, EarlyView.
A global meta‐analysis of 58 studies (926 effect sizes and 29 species across five taxa) revealed that dietary antimicrobial peptides generally improve growth performance, blood metabolites, and immune responses. The greatest benefits were observed in omnivorous livestock, such as pigs and chickens. Dose‐duration effects were evident. An optimal outcome

Mollusk species at a Pliocene shelf whale fall (Orciano Pisano, Tuscany) [PDF]

open access: yes, 2010
The recovery of an intact, 10 m long fossil baleen whale from the Pliocene of Tuscany (Italy) offers the first opportunity to study the paleoecology of a fully developed, natural whale-fall community at outer shelf depth.

Mapping molluscan endocrinology: a systematic and critical appraisal

open access: yesBiological Reviews, EarlyView.
ABSTRACT Historically, a vertebrate‐centric paradigm has framed our interpretation of molluscan endocrinology, with considerable research focusing on vertebrate‐type steroid hormones (e.g. oestrogens, testosterone). However, contradictory evidence on the occurrence of vertebrate‐type steroid hormones in molluscan tissues, and a lack of the specific ...
