“…Our data regarding the rapid physical growth (1 g body weight gain per day from birth to 40 d of age) are consistent with earlier data reporting the similarly fast postnatal body weight gain in captive pup yellow steppe lemmings originated from the same natural population [78]. Among 39 investigated Arvicolinae species, the absolute body weight gain is faster (1.14 g per day) only in the European water vole Arvicola amphibious [90][91][92].…”

Ultrasonic vocalizations (USV) of laboratory rodents may serve as age-dependent indicators of emotional arousal and anxiety. Fast-growing Arvicolinae rodent species might be advantageous wild-type animal models for behavioural and medical research related to USV ontogeny. For the yellow steppe lemming Eolagurus luteus, only audible calls of adults were previously described. This study provides categorization and spectrographic analyses of 1176 USV calls emitted by 120 individual yellow steppe lemmings at 12 age classes, from birth to breeding adults over 90 days (d) of age, 10 individuals per age class, up to 10 USV calls per individual. The USV calls emerged since 1 st day of pup life and occurred at all 12 age classes and in both sexes. The unified 2-min isolation procedure on an unfamiliar territory was equally applicable for inducing USV calls at all age classes. Rapid physical growth (1 g body weight gain per day from birth to 40 d of age) and the early (9-12 d) eyes opening correlated with the early (9-12 d) emergence of mature vocal patterns of USV calls. The mature vocal patterns included a prominent shift in percentages of chevron and upward contours of fundamental frequency (f0) and the changes in the acoustic variables of USV calls. Call duration was the longest at 1-4 d, significantly shorter at 9-12 d and did not between 9-12-d and older age classes. The maximum fundamental frequency (f0max) decreased with increase of age class, from about 50 kHz in neonates to about 40 kHz in adults. These ontogenetic pathways of USV duration and f0max (towards shorter and lower-frequency USV calls) were reminiscent of those in laboratory mice Mus musculus.

“…This author also stated that water voles "probably need to attain a weight of 170 g in order to survive the winter". At the end of the breeding season, adult water voles may reduce their size, possibly to enhance winter survival [28]. These authors stated: "In contrast to other vole species, Arvicola terrestris L. demonstrates increased body weight after parturition relative to that at mating.…”

Weight development in a northern island population of water voles Arvicola amphibius: approaching an optimal weight to survive the winter?

Background: Growth and body size of mammals are commonly correlated with many life history strategies, including those related to survival and reproduction. However, in certain circumstances suboptimal growth rates and smaller size may be advantageous and adaptive. The water vole Arvicola amphibius is a large vole, about three times the size of a field vole Microtus agrestis, but with similar ecological and reproductive characteristics. Island populations were studied on the coast of northern Norway, just below the Arctic Circle, during 2003-2018, by capture-mark-recapture. The main aims were to study growth rates, asymptotic weight and survival, expecting that the “optimal” weight for surviving the winter would be 140-160 g. Results: The smallest juveniles caught weighed only 21 g and were assumed, based on data from the literature, to be around 14 days old. This age was used as starting point for the growth curve. This, however, may have been about one week too early, as juveniles are more likely not fully weaned and leave their nest of birth until 30-40 g. Initial growth rates in juveniles was relatively high but declined from around 100-120 g or 40-50 days old. The asymptotic weight was not clearly defined, but its maximum was around 150-160 g. Most juveniles that survived the winter weighed between 100 and 160 g in their first summer. Large individual variations in growth rates were found. Overwintered subadults in spring weighed about the same as juveniles did in the autumn but grew quickly in April and May to reach adult size. Conclusions: A specific “optimal” weight for juveniles that survived the winter was not found. The range could be given as 100-160 g, too broad to define an “optimal” weight range. However, those that survived tended to be slightly heavier than those that died. Reproducing adults generally weighed 180-220 g and did not reduce their weight toward the autumn, i.e., to increase winter survival, but very few adults survived even the summer and almost none survived their second winter. Juveniles postponed reproduction until next spring, most likely to take advantage of fresh vegetation growth and less competition.

The maximal longterm fluctuations with 1000-fold amplitude and 4 YUZHIK et al ies and laboratory experiments, there was established a direct dependence between reproductive success of females and their offspring, on the one hand, and their energy provision at mating as well as their ability to store up fat during pregnancy, on the other hand [5,6].…”

Fluctuations in water vole population size depend on abiotic and intra-population factors affecting the physiological condition of females. The relationship between reproductive success variability and morpho-physiological indices of females during pregnancy is studied quite poorly. In standard vivarium conditions, the morphometric and hormonal indices of females were assessed at different terms of pregnancy (first trimester-days 4-7, second trimester-days 8-14, third semester-days 15-20), and their relationship with potential and realized fertility and embryonic death rate was examined. The general regression model was used for the data analysis. Positive correlations were found between the potential fertility and the female body mass at mating, condition index, white adipose tissue index, and blood testosterone level. The reproductive indices under study were independent of the blood thyroxin level. A positive correlation was established between the level of embryonic loss and the liver and lung indices. Liver and spleen are essential for the maintenance of the female body mass homeostasis during the reproductive period.
