      indicated by neutral lipid fatty acid patterns.

AB  - Shifting of trophic niches of soil microarthropods may allow them to adapt to 
      changing resource conditions as induced by global change processes. However, the 
      capability of microarthropods to shift their trophic niches is little studied. 
      Whereas some studies based on stable isotopes ((15)N/(13)C) point to distinct and 
      narrow trophic niches, others indicate that trophic niches are plastic. Here, we 
      investigated shifts in trophic niches of oribatid mites (Oribatida, Acari), a 
      major soil detritivore microarthropod group, due to forest management, i.e., 
      plantation of beech and spruce forests in Central Europe, using neutral lipid 
      fatty acid (NLFA) markers. Due to differential microbial communities, we expected 
      a fungi-based diet of oribatid mites in beech forest, but more bacterial 
      contributions to the diet in spruce forest. Supporting these hypotheses, NLFA 
      markers indicated that the trophic niches of each of the studied oribatid mite 
      species differed between beech and spruce forests and shifted from feeding 
      predominantly on litter and fungi in beech forest to more intensively feeding on 
      bacteria in spruce forest. Oribatid mite species with the most pronounced 
      differences in trophic niches included Achipteria coleoptrata, Eupelops hirtus, 
      Eupelops plicatus and Liacarus xylariae, which had been classified as primary or 
      secondary decomposers in previous studies. Overall, the results indicate that the 
      ability of oribatid mite species to colonize different habitats and ecosystems is 
      due to their ability to adjust their diet, i.e., to trophic plasticity. Changes 
      in trophic niches in each of the studied oribatid mite species suggest that 
      detritivores in soil may better cope with future changes in environmental 
      conditions and associated changes in resource composition than species above the 
      ground.
