| Abstract: |
| In order to explore the impact of vegetation types and forest management on the soil oribatid
biodiversity，we investigated the community structure and diversity of soil oribatids in 7 different habitat types in
Tianshan Forest Park，Xinjiang，Northwest China using Tullgren funnel. We captured 21 836 adult individuals
of oribatid mites which belong to 81 genera and 45 families. Among them，Oribatella was the dominant group and
account for 11.24% of the total abundance，Oppiella，Ceratozetes，Jugatala and Rhysotritia were subdominant
groups，and account for 23.58%；21 genera including Trhypochthonius，Camisia and Tectocepheus were common
groups，and account for 49.8 %；55 genera including Eremulus，Galumna and Hoplophthiracarus were rare groups，
and account for 15.38%. The results indicated that there were significant differences in the structure and diversity of
soil oribatid mite communities among different habitats（ P<0.05），the number of individuals in coniferous forest >conifer-broadleaf forest > broad-leaved forest > nursery garden > meadow steppe> shrubbery> grass glade，and the
diversity index represents coniferous forest> nursery garden > broad-leaved forest> shrubbery> conifer-broadleaf
forest> meadow steppe> grass glade. There were significant differences in the spatial and temporal distribution
（P<0.01），the vertical distribution has distinct surface aggregation，while the total abundance was highest in
autumn and the lowest in spring. MGP analysis showed that the soil oribatida community basically belonged to 0 type
and P type. The clustering and sorting results divided seven different habitats into four main types. The results showed
that vegetation type and human disturbance were the dominant factors affecting the structure and diversity of soil
oribatida community in Tianshan Forest Park. |
