Metabolic rate and thermal insulation in albino and hairless mice.
1. Rates of oxygen consumption of albino and hairless mice were measured in a metabolism chamber during periods of approximately 5 or 24 hr. Rectal temperature was measured before and after each period. The chamber temperatures used were 22, 30 and 32 degrees C for both albino and hairless, and in addition 34 and 36 degrees C for the hairless mice.2. The mean age and body weight of the albino m...
متن کاملPrenatal postcranial development in two species of sympatric Japanese wood mice (Apodemus argenteus and A. speciosus): a comparison of arboreal versus terrestrial congeners
Habitats of two closely related Japanese field mice, Apodemus argenteus and A. speciosus, broadly overlap in many Japanese forests. A. argenteus being more arboreal and A. speciosus being more terrestrial, it is thought that such ecological segregation allows their sympatric distribution. Comparing these two congeners, whether ecological difference is reflected in postcranial development was ex...
متن کاملThe estrous cycle in female wood mice (Apodemus sylvaticus) and the influence of the male
Based on studies of vaginal smears from wild-caught Swedish wood mice, females with three types of estrous cycles were identified: females with a continuous estrus; females with an estrous cycle between 6 and 11 days in length; and females that only rarely showed signs of estrus. We tested the pregnancy rates and how stable the estrus patterns were among the females. Ninety-one percent of the f...
متن کاملIndependent Lineage of Lymphocytic Choriomeningitis Virus in Wood Mice (Apodemus sylvaticus), Spain
To clarify the presence of lymphocytic choriomeningitis virus (LCMV) in Spain, we examined blood and tissue specimens from 866 small mammals. LCMV RNA was detected in 3 of 694 wood mice (Apodemus sylvaticus). Phylogenetic analyses suggest that the strains constitute a new evolutionary lineage. LCMV antibodies were detected in 4 of 10 rodent species tested.
متن کاملAge related variations observed in the oral microbiome of wild wood mice, Apodemus sylvaticus
We compared the oral microbiome of wild wood mice (Apodemus sylvaticus) at four ages (18, 22, 26 and 30 weeks). 25 wood mice captured and bred at FERA Science were swabbed orally and the microbial population was characterized by aerobic and anaerobic culture methods followed by 16S rRNA sequencing. The total oral bacterial counts in the wild mice were found to be ~10 cfu/m among all age groups,...
