Agricultural nematologists, vitally fascinated by the examine of the method, taxonomy, and biology of the species because of the direct dating among crop yield and the dimensions of plant-parasitic nematode populations, have supplied a lot information regarding the nematodes. extra lately, ecologists have contributed extra facts at the constitution and serve as of the complete soil group, together with strength movement and nutrient biking, and feature tested the severe and multifaceted position of soil nematodes in such groups. Nematodes in Soil Ecosystems presents a invaluable synthesis of vital study during this sector and should stimulate extra vital verbal exchange among the rural and ecological branches of nematode research.
