Abstract

Abstract: The burrows of small mammals are one of the obvious landscapes in the forest floor, and play important roles in understanding the distribution patterns of small mammals and their ecological functions in the high-frigid regions. Therefore, the burrow selection and habitat characteristics of small mammals were investigated in an alpine forest of eastern Tibet Plateau from July to September in 2015. The results indicated that the average density of small mammals burrow was 182.8 entrances per hectare. Forest vegetation had significant effects on burrow entrances density, which showed the order of coniferous vegetation (328.6 burrow entrances per hectare) > broad-leaved and coniferous mixed vegetation (160.0 burrow entrances per hectare) > shrubbery (125.0 burrow entrances per hectare) > broad-leaved vegetation (81.5 burrow entrances per hectare) > bamboo ve-getation (66.7 burrow entrances per hectare). Mann-Whitney U Test and PCA analysis displayed that the arbor canopy, arbor height, arbor DBH, arbor density, ground-plant cover, fallen log cover, fallen log density and shrub height in the small mammals utilized habitat plots were significantly higher than those in other habitat plots (P<0.05). Compared with other factors, arbor was the primary factor in dominating the selection of small mammal burrows, showing the contribution rate with 44.8%. The following dominant factors were fallen log and shrub, with the contribution rates being 23.2% and 13.9%, respectively. In summary, there were numerous small mammal burrows in the alpine forest floor, which were primarily dominated by vegetation and fallen logs.
