Behaviour indicative of coprophagy in zoo-managed porcupine (Hystrix indica) [PDF]

, 2023
Although all hystricomorph rodents have the colonic furrow or groove that is the anatomical prerequisite for a ‘mucous trap’ colonic separation mechanism linked to coprophagy or cecotrophy, the taxon that gives this group its name, the porcupines, have ...

Update of Cestodes Parasitizing Neotropical Hystricomorphic Rodent

Frontiers in Veterinary Science, 2022
This review aims at identifying cestodes that are present in hunted rodent species in the neo-tropical region. The rodent species that was investigated were the capybara (Hydrochoerus hydrochaeris, Linnaeus, 1766), lappe (Cuniculus paca, Linnaeus, 1766), agouti (Dasyprocta leporina, Linnaeus, 1758), chinchilla (Chinchilla chinchilla, Lichtenstein, 1829)

197 HYSTRICOMORPH SUBPLACENTA: THE COMPARATIVE ASPECTS [PDF]

Reproduction, Fertility and Development, 2004
Placentae of four hystricimorph rodents – capybara (Hydrochaerus hydrochaeris), agouti (Dasyprocta aguti), paca (Agouti paca), and rock cavy (Kerodon rupestris) – were examined by conventional histology, transmission electron microscopy, and scanning electron microscopy.

Synapsids and sensitivity: Broad survey of tetrapod trigeminal canal morphology supports an evolutionary trend of increasing facial tactile specialization in the mammal lineage. [PDF]

Anat Rec (Hoboken)
Abstract The trigeminus nerve (cranial nerve V) is a large and significant conduit of sensory information from the face to the brain, with its three branches extending over the head to innervate a wide variety of integumentary sensory receptors, primarily tactile.

Preliminary investigation on enzymatic activity in saliva of Hystrix cristata L., 1758

Journal of Animal Physiology and Animal Nutrition, Volume 106, Issue 2, Page 387-394, March 2022., 2022
Abstract Mammal's saliva contains a variety of electrolytes and proteins. They carry out an important role in the digestion process, in the antibacterial and antiviral activity, in lubrication and maintenance of oral general health status. It may also contain several enzymes according to dietary habits and general wellness.

Sand accumulation in the digestive tract of rabbits (Oryctolagus cuniculus) and guinea pigs (Cavia porcellus): The role of the appendix

Journal of Morphology, Volume 283, Issue 1, Page 5-15, January 2022., 2022
Serial dorsoventral abdominal CT images of rabbits fed different amounts of sand as part of a serial feeding experiment. Given images are from different individuals in order to create an impression of the reproducibility of the sand's position in the abdomen.

The jaw is a second-class lever in Pedetes capensis (Rodentia: Pedetidae) [PDF]

PeerJ, 2017
The mammalian jaw is often modelled as a third-class lever for the purposes of biomechanical analyses, owing to the position of the resultant muscle force between the jaw joint and the teeth.

Morphological variation in atlas and axis of Neotropical spiny rats (Rodentia, Echimyidae). [PDF]

Anat Rec (Hoboken)
Abstract The unique morphologies of the first two cervical vertebrae, the atlas and axis, represent a significant innovation in mammalian evolution. These structures support the weight of the head and enable intricate movements of the head and neck.
