“…Small mammals typically possess a high metabolic rate and limited physiological adaptability to stress. However, at the population level, these animals demonstrate a notable degree of adaptation [12]. Hence, the assessment of anatomical features, such as the relative organ mass (e.g., heart, kidneys), in narrow-skulled field mice living in the same region, offers valuable insights into the environmental influence on this mammalian species.…”

This study delves into the intricate relationships between ecological factors, adaptation, and the effects of anthropogenic activities on small mammals in the Northeastern region of Kazakhstan. External traits, including body mass, length, tail length, ear height, and hind foot length, provide valuable insights into adaptive adjustments in response to various climatic and ecological conditions. Industrial areas reveal a reduction in average body mass, attributed to patchy vegetation and proximity to factories and roads. Size variations are closely tied to food availability, with a reduction in body size and growth rates observed in technogenic zones. Tail sizes differ by age and sex, while foot sizes tend to even out as animals mature. Notably, anthropogenic pollution has minimal impact on ear length. The heart index reflects an individual’s mobility and thermoregulation, while the liver index is influenced by food availability and energy resources. Notably, the analysis extends beyond average differences, considering the range of variability to identify increased diversity, even in ecologically challenging areas. Small mammals exhibit a high metabolic rate and limited physiological stress adaptability, yet the population demonstrates remarkable adaptation. Enlarged heart indices suggest increased locomotor activity associated with overcoming anthropogenic barriers, such as railways and highways. In addition to heart indices, liver mass calculations reflect the accumulation of energy reserves and materials for growth. The study highlights that the liver mass index of field mice in industrial zones exceeds that of the control group, indicating the impact of anthropogenic activities on these organisms. This research provides valuable insights into the intricate relationships between ecological factors, adaptation, and human influence on small mammal populations in the Northeastern region of Kazakhstan. Keywords: small mammals, narrow-crusted vole, morphophysiological indicators method, exterior signs, interior signs.

The following data was acquired from literary sources and obtained by us as a result of field studies on the distribution, stationality, abundance and reproduction of voles of the genus Blanfordimys Argyropulo, 1933: Afghan vole B. afghanus (Thomas, 1912) with subspecies B. a. afghanus and B. a. balchanensis (Heptner et Shukurov, 1950), Bukhara vole B. bucharensis (Vinogradov, 1930), with subspecies B. b. bucharensis and B. b. davydovi (Golenishchev et Sablina, 1991) and Pamir vole B. juldaschi (Severtzov, 1879) with subspecies B. j. carruthersi (Thomas, 1909) and B. j. juldaschi in natural conditions on the territory of Turkmenistan, Tajikistan and Kyrgyzstan. According to the elevation gradient from low to high altitude, these voles are distributed as follows: Afghan, Bukhara, Pamir, respectively. The features of reproduction and postembryonic ontogenesis in captivity have also been studied. Reproduction took place year-round with low intensity: the number of newborns in the litter of all the species considered is small, 3 cubs on average, the average interval between litters is about 50 days. The young of voles living at lower altitudes (B. afghanus and B. bucharensis) develop somewhat faster compared to higher-altitude ones (B. juldaschi). In general, the studied species showed signs of slow development and delay in the appearance of the most important signs in postembryonic ontogenesis (eruption of incisors, epiphany) compared to most of the lowland representatives of the Arvicolini tribe voles. These features are more pronounced in B. j. juldaschi, living at high altitudes. Thus, considering the theory of pace-of-life syndrome (POLS), we observe a shift from a faster pace of life (r-strategy), characteristic of most lowland rodents, to a slower one (k-strategy). The vulnerability of voles of the genus Blanfordimys in the process of climate aridization and in conditions of anthropogenic pressure is noted.
