Due to their high abundance in soil and diversity of responses to disturbances, nematodes are suitable indicators for environmental monitoring. However, the time-consuming nature of microscopic analysis of nematode communities so far hampered the scale at which this indicator group is used.
In this article (see link Article in PLOS ONE), results are presented of the first field test of a molecular tool for the quantitative analysis of nematode assemblages. As a starting point, a phylum-wide molecular framework consisting of 2,400 full-length SSU rDNA sequences (appr. 1,700 base pairs each) was used.
