摘要: The composition of nematode communities (plant-parasitic and free-living) may be used as bioindicators soil health or condition because correlates well with nitrogen cycling decomposition, two critical ecological processes in soil. Maturity trophic diversity indices withstand statistical rigor better than do abundances, proportions, ratios groups. respond to a variety land-management practices, based largely on inferred life history characteristics families. Similarity more useful they reflect taxon composition. Improving existing developing alternative refined by greater understanding the biology key taxa enhance utility nematodes bioindicators.
