ON THE DISTRIBUTION AND REPRODUCTIVE BIOLOGY OF THE MIDDAY GERBIL (MERIONES MERIDIANUS PALL.) IN THE KYZYLKUM DESERT
Аннотация
This study examines the distribution, morphological characteristics, population dynamics, and reproductive biology of the midday gerbil (Meriones meridianus Pall.) in the Kyzylkum Desert. Field research was conducted in the Nukus Sands region using trapping methods, direct observations, morphological assessments, and comparative analysis of literature data. The results indicate that the species is widely distributed in sandy habitats with moderately developed vegetation, which provide favorable conditions for burrowing and feeding. Population dynamics exhibit both long-term and short-term fluctuations, strongly influenced by food availability and climatic conditions. Reproductive activity varies significantly between years, with higher proportions of pregnant females and increased embryo numbers observed under favorable environmental conditions. The species demonstrates considerable ecological adaptability, including flexible habitat use and interaction with other rodent species. These findings highlight the important ecological role of the midday gerbil in desert ecosystems and its sensitivity to environmental variability.
