Global Overview of the Functional Roles of Soil-living Nematodes in Terrestrial Communities and Ecosystems.

摘要: The role of soil-living nematodes in different ecosystems can be largely predicted by the intensity nonbiotic stresses imposed temperature and moisture regimes. Assuming that tropical lowland rain forest experiences most biologically equitable climate, increasing climate-related stress occurs as one proceeds through intervening biomes to low latitude desert, high alpine desert. Soil nematodes, being mostly relative generalists, show only moderate diversity densities forests because competition from many other more specialized organisms. On hand, nematode increase remain relatively extreme greater adaptability than do taxa climate-induced stress. However, cold allows "ecological release" does drought essentially aquatic organisms, require for activity. Thus, have greatest diversities densities.
