Nematodes in Soil Ecosystems

Many species of the phylum Nematoda, the nonsegmented worms, play an important role as animal or plant parasites; most species are active contributors to the decomposition cycle in soil ecosystems, but the details of that contribution are just beginning to be understood.

Agricultural nematologists, vitally involved in the study of the methodology, taxonomy, and biology of the species due to the direct relationship between crop yield and the size of plant-parasitic nematode populations, have...
