Desoria

Cold environments including supraglacial stony debris, subnivean (under snow), intranivean (in snow), and supranivean (on snow surface) microhabitats; alpine glaciers, snow-covered forestland and cropland, and Antarctic ice-free areas.

Widely distributed in cold regions: Central Apennines, Italy (Calderone glacier); northern Victoria Land, Antarctica; northern China (Jilin Province); and diverse snow-covered habitats globally.

Active in winter at low temperatures (0°C–5°C); maintains activity when food resources are limited in snowy environments.

Maintains activity in extremely cold environments; tolerates low temperatures where other arthropods are dormant.

Contributes to soil biodiversity during winter; host-microbiota interactions sustain soil biodiversity in cold environments; microbiota associated with nutrient turnover and stable isotope enrichment patterns.

Some species (e.g., Desoria ruseki) used in laboratory studies examining microbiota-host relationships and stable isotope ecology; climate change poses extinction risk for glacial-dependent species, making them potential indicators of cryospheric change.
