Koedoe: African Protected Area Conservation and Science, 1979 The history of classification ofAfrotropical molerats is reviewed and an assessment is made of the supposed taxonomic "isolation" of the molerats (bathyergids) by considering morphological features in the skull, post-cranial skeleton, reproductive organs

I W Rowlands, Barbara J Weir and the biology of the hystricomorph rodents
Reproduction, 2023 In brief Current research on the genomics, ecology and reproductive biology of hystricomorph rodents relies on the pioneering studies of B J Weir and I W Rowlands. We show the enduring influence of a symposium on hystricomorph biology held 50 years ago.

Crepuscular Rhythms of EEG Sleep-Wake in a Hystricomorph Rodent, Octodon degus [PDF]
Journal of Biological Rhythms, 1998 Sleep-wake circadian rhythms are well documented for nocturnal rodents, but little is known about sleep regulation in diurnal or crepuscular rodent species. This study examined the circadian sleep-wake rhythms in Octodon degus by means of electroencephalogram (EEG) analysis. Recordings were made from animals housed with or without running wheels in the

Pulmonary trophoblastic deportation in the hystricomorph rodent Lagostomus maximus
PlacentaTrophoblast has been reported in the lungs of gestating eutherian mammals with hemochorial placenta, including humans, cotton rats, and American hares. This study describes the discovery of trophoblastic-like cells in the lungs of Lagostomus maximus.Lung and placenta samples from non-pregnant and pregnant plains viscachas were analyzed using histology ...

Digestive physiology of the plains viscacha (Lagostomus maximus): a large herbivorous hystricomorph rodent [PDF]
Zoo biology, 2015 Plains viscachas (Lagostomus maximus) are large South American, fossorial rodents susceptible to diabetic cataracts. Various aspects of their digestive physiology were studied in three different experiments with 9 male and 7 female adult animals and 6 different diets (total n of feeding trials = 35).

The Impact of Food Properties on Jaw Movements in Rodents: A Comparison Between Myomorphous and Hystricomorphous Species. [PDF]
J MorpholWe investigated the masticatory movements of two of the three main cranial‐mandibular morphological groups in Rodents (two species each) using 3D X‐ray reconstruction. We found that both groups use different movements and modulate their chewing differently in response to different food items.

The morphology of female genitalia in Galea spixii (Caviidae, Caviinae) [PDF]
Bioscience Journal, 2014 The yellow-toothed cavy (Galea spixii) is a hystricomorph rodent of the Caviidae family. In Brazil, G. spixii are bred in captivity to provide an alternative protein source and to preserve the specie.

Comparing cranial biomechanics between Barbourofelis fricki and Smilodon fatalis: Is there a universal killing-bite among saber-toothed predators? [PDF]
Anat Rec (Hoboken)Abstract Saber‐tooths, extinct apex predators with long and blade‐like upper canines, have appeared iteratively at least five times in the evolutionary history of vertebrates. Although saber‐tooths exhibit a relatively diverse range of morphologies, it is widely accepted that all killed their prey using the same predatory behavior. In this study, we CT‐

Two rodent suborders have evolved missing amino acids in the lipid-binding region of apolipoprotein E. [PDF]
LipidsAbstract The order Rodentia comprises nearly 45% of all extant taxa, currently organized into 31 living families, some 450 genera, and roughly 2010 species (Kelt & Patton, 2020). Considering that rodents began evolving at least 66 million years ago, it is not surprising that they have diversified into five distinct suborders.

Reproductive Technologies Used in Female Neo-Tropical Hystricomorphic Rodents [PDF]
Animals, 2021 This is the second of two literature reviews that focuses on the female reproductive anatomy and reproductive technologies used in selected neo-tropical hystricomorphic rodents. The rodents chosen included the agouti (Dasyprocta leporina), the capybara (Hydrochoerus hydrochaeris), and the paca (Cuniculus paca).
