The habitat distribution and environmental characteristics of dwarf hamsters are as follows:
I. Natural Distribution Areas
Continental Asia
- Mainly found in northern China, Mongolia, Kazakhstan, and Siberia (Russia).
- In China, commonly seen in grasslands and semi-desert zones of Inner Mongolia, Xinjiang, and other regions.
Typical Habitat Environments
- Grassland Semi-Deserts: Sparse vegetation on sand dune areas, adapted to arid climates.
- Forest-Steppe Edges: Shrubby zones near cultivated lands.
- Farmland Periphery: Some populations inhabit areas close to human croplands.
II. Survival Adaptability
Burrowing Traits
- Nocturnal burrowing animals that dig underground tunnel systems to evade predators.
- Nests can reach 30–50 cm in depth, used for cold protection in winter.
Extreme Environment Adaptations
- Cold Tolerance: Siberian populations develop white winter fur (winter white phenomenon).
- Water Conservation: Reduces water loss by concentrating urine.
III. Artificial Breeding Recommendations
Environmental Simulation Essentials
- Bedding thickness should be ≥10 cm to satisfy burrowing instincts.
- Maintain temperatures at 20–25°C and avoid direct sunlight.
Behavioral Observations
- Active at night, mostly hidden beneath bedding during the day.
- Wild individuals often hoard food; provide hiding spaces for food storage in captivity.
Note: Slight habitat differences exist among dwarf hamster species (e.g., Djungarian hamsters, Campbell’s hamsters).
