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)

The Ear in Subterranean Rodents Revisited: Cochlear Hair-Cell Populations in African Mole-Rats (Bathyergidae). [PDF]

J Morphol
Morphometric analysis of the cochlea was conducted on 12 species of African mole‐rats (Bathyergidae), revealing that cochlear features related to hearing resolution correlate with body size. Compared to other mammals, bathyergid cochleae resemble the apical, low‐frequency‐tuned regions of typical mammalian cochleae.

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.

Understanding how environmental factors influence reproductive aspects of wild myomorphic and hystricomorphic rodents [PDF]

Animal Reproduction, 2021
Myomorphic and hystricomorphic rodents are vital for maintaining various ecosystems around the planet. This review enables a better understanding of how these rodents respond to environmental factors and adapt to climate adversities. Innumerable factors, such as photoperiod, rainfall, and temperature, can impair or contribute to the quality of rodent ...

Validation of a radioimmunoassay for measuring fecal cortisol metabolites in the hystricomorph rodent, Octodon degus.

Journal of Experimental Zoology Part A: Ecological Genetics and Physiology, 2009
AbstractDetermination of fecal steroid metabolites is a noninvasive technique that characterizes the physiological state of organisms without the physiological and psychological stress of handling. Although this technique has many applications in the study of wildlife and/or captive animals without the necessity of capturing individuals, it requires a ...

Progesterone-binding proteins in plasma of guinea-pigs and other hystricomorph rodents. [PDF]

Reproduction, 1981
Progesterone-binding plasma proteins (PBPP, progesterone-binding globulin, PBG, and corticosteroid binding globulin, CBG) have been measured in plasma of guinea-pigs, casiragua, cuis, degu and plains viscacha. During pregnancy PBPP increased to reach peak values between Days 20-25 and Days 50-term in guinea-pigs, immediately before parturition in ...

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.

Demography and Population Dynamics of a Small Mammal Assemblage in Chilean Semiarid Thorn-Scrub Habitat: A 30-Year Study. [PDF]

Ecol Evol
Using the longest and most comprehensive demographic database available in temperate South America, we characterize the population dynamics of an entire community of small mammals in a semiarid environment in north‐central Chile using a superpopulation CMR modeling framework.
