DIVERSITY AND SPATIAL DISTRIBUTION OF SOIL COLLEMBOLA FAUNA AROUND NAVOI MINING AND METALLURGY COMBINAT
This study examines soil Collembola diversity around Navoi Mining and Metallurgy Combinat (NMMC) in Uzbekistan. Soil
samples were collected at three distances (0.5 km, 2 km, 5 km) during winter months (November 2025, December 2025, January
2026), with nine replicates per location (27 total samples). Five species were identified: Folsomia candida, Isotoma viridis,
Entomobrya nivalis, Sminthurus viridis, and Hypogastrura viatica. Results showed significant biodiversity increase with distance
from the industrial facility. Shannon diversity index increased from 0.00 at 0.5 km to 1.89 at 5 km. Total abundance increased
3.3-fold (89 to 297 individuals). Statistical analysis confirmed highly significant differences among distance groups (p<0.001).
Species-specific responses revealed differential pollution tolerance patterns. This research establishes baseline data for
biomonitoring programs in Central Asian mining regions.
