| Summary: | This data describes above-ground and below-ground variables collected under small mammal-built structures and control sites from two tundra locations in polygonal tundra near Utqiagvik, Alaska, USA. Small mammal structures sampled included hay piles (winter nests), runways, latrines, and burrow entrances. Above-ground data collected include relative percent cover, litter depth, and Normalized Difference Vegetation Index. Below-ground data collected include inorganic soil nutrients, total extractable soil nutrients, microbial biomass nutrients, microbial exo-enzyme activities, soil pH, soil conductivity, soil temperature, and soil respiration.
