Behavioural mechanisms underlying infant care in male and female Mongolian gerbils
… several species. Male and female adult Mongolian gerbils, Meriones unguiculatus were singly exposed to protected pups (PP exposures). Exposures lasted for ten minutes, and were carried out each day. Behaviour patterns shown by the adults were recorded, and their frequencies measured. After several …

The Effects of Naturally Occurring Plant Products on Experimental Haemonchus contortus Infection in Gerbils and Sheep
… experimental Haemonchus contortus infection in gerbils and sheep. In gerbil assays, animals were orally infected with 600 third-stage Haemonchus larvae and treated once or daily for 5 days with artemisinin, Artemisia annua aqueous or ethanolic extract, an orange oil emulsion, or Asimina triloba …

Patterns of intraspecific and intergeneric agonistic behavior in the male and female Mongolian gerbil (<i>Meriones unguiculatus</i>)
… gerbil. Six adult female and six adult male gerbils were established in individual home cages. Over a period of 4 weeks, individual intruders (either a male or female gerbil or a male or female SJL mouse) were placed in the home cage. The resulting outcomes of the social interactions between …

Impact of Dietary Composition and Beta-Carotene Isomeric Structure on Bioconversion of Beta-Carotene to Vitamin a in Gerbils
In conclusion, betaC bioconversion to VA was independently and adversely affected by consumption of low dietary fat and citrus pectin. 9-Cis betaC was less and 13cbetaC was more than the currently assigned retinol equivalency of 50% of atbetaC. Thus, the actual contribution of betaC to the VA …

Charakterisierung der Helicobacter pylori-assoziierten Magenadenokarzinogenese am Tiermodell des Mongolischen Gerbils: Rolle der cag-Pathogenitätsinsel bei der Induktion präkanzeröser Prozesse.
… im Magen am Modell des Mongolischen Gerbils zu analysieren. Mit Hilfe einer Zeitverlaufsstudie konnte zum ersten Mal gezeigt werden, dass eine frühzeitig hochgradige Entzündung der Antrum- und Korpusmukosa zu späten physiologischen Veränderungen führt (Hypochlorhydrie und …

Seed dispersal by black-backed Jackals (Canis mesomelas) and hairy-footed gerbils (Gerbillurus spp.) of !nara (Acanthosicyos horridus) in the central Namib Desert
… seed dispersal by scatter-hoarding hairyfooted gerbils (Gerbilliscus (Gerbillurus) spp.) in the central Namib Desert. This was accomplished by examining visitation rates and fruit removal of !nara melons, primarily by jackals. In addition, I determined the viability and germination rate of !nara …

Effect of Soy Protein, Isoflavones and Methionine Supplementation on Lipid Metabolism
… from our time course experiment indicated that gerbils fed casein had higher serum total cholesterol concentrations compared to gerbils fed alcohol-washed, essentially isoflavone-free isolated soy protein (ISP). This effect was statistically significant at day-14 and continued on day-21 where …

The effects of lavandula angustifolia on animal and human laboratory models of anxiety
… model of anxiety in both male and female gerbils, a model that has only previously been validated in female gerbils (Varty et al., 2002). Second, the studies on gerbils have shown that both lavender and rose essential oils have anxiolytic effects, which, rather than dissipating following …

Surveillance of the rabies-related lyssavirus, Mokola, in small non-volant mammals in South Africa and Mozambique
… exposure and were all collected from Bushveld gerbils (Gerbilliscus leucogaster) in both South Africa (n=36) and Mozambique (n=1). From all of the Bushveld gerbils that were tested, an overall MOKV seropositivity of 87.80% is observed for the gerbils that were caught at Meletse in Limpopo. …

Sex differences in the actions of psychoactive agents and progesterone on anxiety-related behaviour in the mongolian gerbil (meriones unguiculatus) and the effects of corticosterone on the hippocampal morphology of wistar rats (rattus norvegicus)
… tests of anxiety for male and female Mongolian gerbils. The second part of this thesis then evaluates the behavioural effects of progesterone treatment and withdrawal in this species. Finally, this thesis evaluates the influence of chronic corticosterone treatment on hippocampal volume and …

Denoising techniques reveal neural correlates of modulation masking release in auditory cortex
… explores neural correlates of MMR in NH and HI gerbils. Trained, awake gerbils (Meriones unguiculatus) listen passively to a target tone (1 kHz) embedded in modulated or unmodulated noise while a 16-channel microelectrode array records multi-unit neural spike activity in core auditory cortex. In …

Identifying the Cellular Sources of the Low-Frequency Cochlear Response
… potential recorded from the round window in gerbils to low-frequency tones contains responses from a number of cellular sources in addition to and, in some high-pass noise conditions, more substantial than the outer hair cell response. A model is created from data found in existing literature …

Development of Auditory Sensitivity in Barn Owls (Tyto furcata pratincola)
… including kittens, budgerigars, chickens, and gerbils. The onset of hearing began sometime earlier than the second week post-hatch, and proceeded in a frequency-dependent manner. Adult-like thresholds were reached in a progression from low to high frequency, and sensitivity was mature by P60. …

Consuming a diet enriched with choline, UMP, and DHA improves memory in rodents when these compounds increase phospholipids
… effects of the treatment in individual rats or gerbils subsequently shown to manifest its neurochemical effects (i.e., increased phosphatides). My present findings show that the treatment improves performance on various tests of memory function. The largest improvements in memory function and …

The demography of Balanites maughamii : an elephant-dispersed tree
… Cafeteria experiments revealed that bushveld gerbils (Tatera leucogaster) were removing many seeds but do not scatter- or larder-hoard. They are simply seed predators.

Cochlear morphology and sound-induced motion of the apical mammalian inner ear
… study the structure of the inner ears of mice, gerbils, and guinea pigs, as well as the acoustic response of the apical turn of in vitro and in vivo apical mammalian cochleae to low frequency (100 to 1000 Hz) sounds - frequencies that are critical to our understanding of speech.

Pathogenic and antigenic characterization of <I>Neospora hughesi</I>

Anatomical identification of primary auditory cortex in the developing gerbil
