I W Rowlands, Barbara J Weir and the biology of the hystricomorph rodents [PDF]
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.

Molerats (Bathyergidae, Rodentia) in South African National Parks: notes on the Taxonomic "isolation" and Hystricomorph Affinities of the family [PDF]
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

Crepuscular Rhythms of EEG Sleep-Wake in a Hystricomorph Rodent, Octodon degus [PDF]
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

Digestive physiology of the plains viscacha (Lagostomus maximus): a large herbivorous hystricomorph rodent [PDF]
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).

Embryonic and fetal morphology in the lowland paca (Cuniculus paca): A precocial hystricomorph rodent [PDF]
In mammals, the embryonic and fetal development of a species has evolved to maximize neonatal survival. In this study, we use a sample of 132 embryos/fetuses of wild lowland paca (Cuniculus paca), obtained over a period of 15 years through collaborative methods with local hunters in the Amazon to describe the intrauterine development of external and ...

Melatonin binding sites in sciurid and hystricomorph rodents: studies on ground squirrels and guinea pigs [PDF]
Little is known about the distribution of binding sites for the pineal hormone melatonin in non-myomorph rodents. We used 2-[125I]iodomelatonin (IMEL) to analyze the distribution, affinity, and specificity of binding sites in the golden-mantled ground squirrel, a sciurid rodent that reportedly lacks IMEL binding sites in the brain. Specific binding was

The morphology of female genitalia in Galea spixii (Caviidae, Caviinae) [PDF]
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.

Morphology of the lower deciduous premolars of South American hystricomorph rodents and age of the Octodontoidea [PDF]
AbstractWe analyse the crest homologies of lower deciduous premolars (Dp4) of South American caviomorphs in a comparative context including other hystricomorphs and under a dynamic topological crit...

Comparing cranial biomechanics between Barbourofelis fricki and Smilodon fatalis: Is there a universal killing-bite among saber-toothed predators? [PDF]
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]
Abstract 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.
