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 ...

The accelerating influence of humans on mammalian macroecological patterns over the late Quaternary [PDF]

, 2019
The transition of hominins to a largely meat-based diet ~1.8 million years ago led to the exploitation of other mammals for food and resources. As hominins, particularly archaic and modern humans, became increasingly abundant and dispersed across the ...

Diversity and Conservation of Carnivores in Saudi Arabia

Diversity
In the present study, we updated the taxonomy and distributional data for 14 carnivore species based on previous records and the recent results of camera trapping (4787 camera nights from 58 locations) and depicted species richness.

Evolutionary Impacts of Pattern Recognition Receptor Genes on Carnivora Complex Habitat Stress Adaptation

Animals, 2022
Many mammals develop specific immune responses owing to the changes in their ecological niche and diet that are essential for animal survival. However, pattern recognition receptors (PRRs) serve as the first line of defense in innate immunity and ...

Bite Force and Masticatory Muscle Architecture Adaptations in the Dietarily Diverse Musteloidea (Carnivora)

The Anatomical Record, 2019
Dietary ecology and its relationship with both muscle architecture and bite force potential has been studied in many mammalian (and non‐mammalian) taxa. However, despite the diversity of dietary niches that characterizes the superfamily Musteloidea, the ...

The relationship between form and function of the carnivore mandible

The 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 ...

Ecomorphological determinations in the absence of living analogs:The predatory behavior of the marsupial lion (Thylacoleo carnifex) as revealed by elbow joint morphology [PDF]

, 2016
Thylacoleo carnifex, or the “pouched lion” (Mammalia: Marsupialia: Diprotodontia: Thylacoleonidae), was a carnivorous marsupial that inhabited Australia during the Pleistocene.

Carnivora population dynamics are as slow and as fast as those of other mammals: implications for their conservation. [PDF]

PLoS ONE, 2013
Of the 285 species of Carnivora 71 are threatened, while many of these species fulfill important ecological roles in their ecosystems as top or meso-predators.

The extraordinary evolutionary history of the reticuloendotheliosis viruses [PDF]

, 2013
The reticuloendotheliosis viruses (REVs) comprise several closely related amphotropic retroviruses isolated from birds. These viruses exhibit several highly unusual characteristics that have not so far been adequately explained, including their extremely
