Urine composition of some hystricomorph rodents confined to metabolism cages

Comparative Biochemistry and Physiology Part A: Physiology, 1972
Abstract 1. 1. A comparison was made of the composition of urine from six species of hystricomorphs (chinchilla, plains viscacha, degu, cuis, native guinea-pig and domestic guinea-pig) maintained under laboratory conditions. 2. 2. All species produced moderate amounts of hypertonic urine and daily rhythms in water and electrolyte excretion ...

STUDIES ON THE ENDOPARASITIC FAUNA OF TRINIDAD MAMMALS: VII. PARASITES OF HYSTRICOMORPH RODENTS

Canadian Journal of Zoology, 1951
A possible new variety of cestode, Raillietina (R.) demerariensis var. trinitatae, and two new varieties, Trichuris gracilis var. trinitatae and Aspidodera binansata var. agoutiae and a new species of nematode, Helminthoxys urichi are recorded from the agouti and lappe from Trinidad, B.W.I.

Head myology of wild cavies (Caviidae, Caviomorpha) and functional implications of hystricomorphous and hystricognathous configurations

Journal of Mammalian Evolution, 2023
Cavies are one of the most-specialized grinding rodents, with folivorous and grass-based diets. Antecedents on head myology are focused mainly on domestic guinea pig. Here, we analyze three specimens of wild caviines (two of Cavia aperea and one of Galea leucoblephara), describing, illustrating, mapping, and weighing facial and masticatory muscles ...

Melatonin binding sites in sciurid and hystricomorph rodents: studies on ground squirrels and guinea pigs

Brain Research, 1994
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

Morphology of the lower deciduous premolars of South American hystricomorph rodents and age of the Octodontoidea

Historical Biology, 2018
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...
