“…The hamsters were placed in a helium-oxygen (80%:20%) atmosphere for 18 min at an ambient temperature of 7 °C. In similar experiments with desert hamsters, no correlation was found between oxygen consumption and ambient temperature within 6-10 °C (Moshkin et al 2002). Consequently, the oxygen consumption values obtained at 7 °C can be considered as an indicator of the maximum aerobic performance.…”

We tested the winter immunity enhancement hypothesis (WIEH) on male desert hamsters (Phodopus roborovskii) kept under long-day (LD) and short-day (SD) photoperiods. We assumed that under SD in a laboratory, the adaptive humoral immune responsiveness to the antigenic challenge would be enhanced due to the lack of winter physical stressors and food shortages and/or because of the action of an endogenous winter bolstering mechanism, while under LD the immune responsiveness would be suppressed by the activity of the reproductive system. The results support the WIEH in part. We did not find a difference in antibody production in response to sheep erythrocytes between SD and LD hamsters, but SD males had the lower number of granulocytes and the higher number of lymphocytes in white blood cell counts. Reproductive activity was lower in SD males. These males demonstrated an increase in their mass-specific resting metabolic rate, their mass-specific maximal metabolic rate and their level of cortisol. The result of a generalized linear model analysis indicates the negative effect on secondary immunoresponsiveness to sheep erythrocytes of mid-ventral gland size, the organ characterizing individual reproductive quality, and designates a tradeoff between antibody production and reproductive effort. The mass-independent maximal metabolic rate also negatively affected antibody production, indicating a tradeoff between maximal aerobic performance and the adaptive immune function. The higher stress in SD males seems to be the most likely reason for the lack of the effect of daylight duration on antibody production.

“…One explanation for the lack of relationship between corticosterone concentration and BKA and time held is that mole-rats may simply produce low levels of glucocorticoid after acute stress. There is evidence that fossorial rodents, living in relatively stable microclimatic conditions, are adapted to environments with fewer extreme external stressors and are thus less reactive to stress (Moshkin et al, 2002).…”

“…The level of corticosterone, which is the main stress hormone in Spalax syn. Nannospalax and other subterranean rodents (Ganem and Nevo, 1996;Moshkin et al, 2002;Vera at al., 2012), was measured in serum using a commercial enzyme immunoassay kit, following the instructions provided (DetectX ® Corticosterone Enzyme Immunoassay Kit). Samples were run in duplicate, and we calculated the coefficient of variation to determine the repeatability of our corticosterone measurements.…”

“…The level of corticosterone, which is the main stress hormone in mole voles (Moshkin et al 2002;Novikov et al 2004), was measured in dry faeces using an enzyme immunoassay, according to the instructions for the corticosterone EIA kit (Enzo Life Sciences, USA). For this procedure, 150 lL of ethanol extract (40 mg/mL) was dried and added to 200 lL of phosphate buffer (pH 7.4).…”

Reproduction, aging and mortality rate in social subterranean mole voles (Ellobius talpinus Pall.)

Eusocial subterranean rodents of the Bathyergidae family have enormous longevity. The long lifespan of these species is associated with negligible senescence, that is, an absence of the signs of age-related deterioration in physical condition. The question arises as to whether these features are unique to eusocial Bathyergids or typical of other social subterranean rodents as well. In the present study, we analysed data from observations of a social subterranean Microtinae rodent, the northern mole vole (Ellobius talpinus Pall.), which, like mole-rats, has reproductive skew. Among the individuals captured in the wild and maintained in captivity, females that reproduced lived significantly longer than non-breeding females. We did not find any changes in muscle strength with age in any of the demographic groups studied. Faecal glucocorticoid concentrations before death were significantly higher in non-breeding females than in breeding females and males. Increased adrenocortical activity may be one mechanism responsible for the decreased lifespan of non-reproducing individuals of social subterranean rodents. We conclude that the patterns of aging, although different in some respects, are generally common for social subterranean rodents of different taxonomic groups.
