soil ecosystem
The smallest amount of fungi (54-59%) is found in the arable soil ecosystem.
      
Tillage affected nematode communities in the soil ecosystem by changing the trophic structure and gave a decreasing, but not statistically significant, trend in MI.
      
Most caecilians are thought to be generalist predators of soil ecosystem engineers (earthworms, termites and ants), but it has been suggested that members of the East African genus Boulengerula are specialist predators.
      
To analyse nematode community structures appropriately for the evaluation of soil ecosystem status and function requires information on the life history traits of K-strategic nematodes.
      
The purported benefits of conservation tillage and continuous cropping in agricultural systems include enhancement of soil ecosystem functions to improve nutrient availability to crops and soil C storage.
      
Understory flora and community physiognomy of planted forests in the degraded purple soil ecosystem, South China
      
Four different restoration communities (labeled as ecological restoration treatment I, II, III and IV) were selected by space-time replacement method according to the erosion intensity in degraded purple soil ecosystem.
      
The results showed that there were totally 86 plant species belonging to 78 genera and 43 families in the degraded purple soil ecosystem.
      
Of the 15 types of distribution area in spermatophyte genus, 12 types were found in the purple soil ecosystem.
      
The vegetation-litter-soil ecosystem stored 452624 t·a-1 of carbon, which was the important CO2 sink.
      
The net carbon storage was currently 3146 t·a-1 in vegetation-litter-soil ecosystem.
      
Time-resolved fluorescence spectroscopy was used to characterize water-soluble organic matter (WSOM) which plays an important role in soil ecosystem processes.
      
The results of this study demonstrate the importance of moisture availability to the nematode community and its species composition in this Antarctic soil ecosystem.
      
Microorganisms, as primary colonists, are integral to Antarctic soil ecosystem development, essential for pedogenesis and structuring the soil, and providing the nutrients necessary for the subsequent establishment of macroorganisms.
      
The results show that not only the Enchytraeidae but even single species like Cognettia sphagnetorum or Mesenchytraeus glandulosus contribute a measurable amount to the energy flow of the soil ecosystem.
      
In addition to measures to reduce the input of atmospheric deposition, removal of the ectorganic layers by sod-cutting may contribute to the recovery of the soil ecosystem.
      
In a Dutch Scots pine forest an experiment was conducted to quantify the role of soil biota in the functioning of the soil ecosystem, and the effects of enhanced nitrogen deposition.
      
Earthworms may alter the physical, chemical, and biological properties of a forest soil ecosystem.
      
Any physical manipulation of the soil ecosystem may, in turn, affect the activities and ecology of earthworms.
      
The maturity index, based on the nematode fauna, is proposed as a gauge of the condition of the soil ecosystem.
