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 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 ...

Morphology of the Lingual Papillae in the Raccoon Dog and Fox

Okajimas Folia Anatomica Japonica, 2006
The dorsal lingual surfaces of the raccoon dogs (Nyctereutes procyonoides) and fox (Vulpes vulpes japonica) were examined by scanning electron microscopical (SEM) observations. The distribution and type of the lingual papillae found in the raccoon dog were similar to those in the fox. Filiform, fungiform, foliate and vallate papillae were observed. The

Seasonal Physiology of the Wild Raccoon Dog (Nyctereutes procyonoides) [PDF]

Zoological Science, 2004
The raccoon dog (Nyctereutes procyonoides) is a canid omnivore with autumnal fattening and winter sleep. Farmraised raccoon dogs have elevated plasma leptin and growth hormone levels in the winter and depressed plasma cortisol and insulin concentrations during wintertime food deprivation. However, these parameters were not previously tested in the wild

Host, vector, and parasite dynamics: exploring intrinsic and extrinsic factors shaping tick‐borne filarial nematode transmission

Biological Reviews, EarlyView.
ABSTRACT Tick‐borne filarial nematodes are a complex and understudied group of parasites that rely on ticks for transmission in vertebrates. This review examines how intrinsic and extrinsic factors may influence the successful transmission of filarial nematodes in tick vectors, drawing insights from extensively studied haematophagous dipteran vector ...

Alien predation in wetlands : the Raccoon dog and waterbird breeding success

, 2019
Alien predators are known to potentially strongly affect their prey populations. We studied the impact of raccoon dogs (Nyctereutes procyonoides) on waterbird breeding success in eight semi-urban wetlands in Finland. We manipulated raccoon dog density in

How wildlife respond to tropical cyclones: short‐term tactics and long‐term impacts

Biological Reviews, EarlyView.
ABSTRACT From butterflies to lizards and from sharks to seabirds, wildlife exhibit tactics to survive the impacts of tropical cyclones, also known as hurricanes, cyclones, or typhoons depending on where they occur. Some species seek refuge during the storm by moving, some remain in place and ride it out, and others move longer distances, avoiding the ...

Habitat Use by Introduced Raccoons and Native Raccoon Dogs in a Deciduous Forest of Japan [PDF]

Journal of Mammalogy, 2007
We investigated habitat use by introduced raccoons (Procyon lotor) and native raccoon dogs (Nyctereutes procyonoides albus) in a northern deciduous forest of Japan to examine the relationship between the 2 species. Spatial and temporal habitat use in the forest was monitored using infrared-triggered cameras.

Distribution and frequency of Vkorc1 polymorphisms in house mice and Norway rats in the northeastern United States

Pest Management Science, EarlyView.
This study assesses the distribution and frequency of Vkorc1 polymorphisms in house mice and Norway rats in northeastern USA. House mice showed higher frequency of Vkorc1 mutations than Norway rats. The A32V and Y139F mutations are first reported in mice, and the L128V is newly reported in Norway rats.
