A framework for soil food web diagnostics : extension of the nematode faunal analysis concept
This work enhances the resolution of faunal analyses by providing a weighting system for the indicator importance of the presence and abundance of each functional guild in relation to enrichment and structure of the food web.
Form and function: Metabolic footprints of nematodes in the soil food web
Standardized metabolic activity levels, attributable to the abundance of nematodes performing various functional roles, can be calculated from existing and accessible morphometric data.
Effects of long-term crop management on nematode trophic levels other than plant feeders disappear after 1 year of disruptive soil management
BI and CI appeared to be most valuable as indicators for long-term effects of management on nematode suppression, since CI can be high in highly disturbed agro-ecosystems as well as in undisturbed natural ecosystems.
Dynamics of nematode communities in tomatoes grown in conventional and organic farming systems, and their impact on soil fertility
It is hypothesize that increasing abundance, biomass and activity of these nematodes in the spring by organic matter incorporation at the end of the previous crop would reduce the observed nitrogen stress.
Nitrogen mineralization by bacterial-feeding nematodes: verification and measurement
In experiments with different nematodes species, net mineralization and the nematode contribution to mineralization generally decreased with increasing C-to-N ratio, consistent with the hypothesis; however, there were exceptions.
Two semi-automatic elutriators for extracting nematodes and certain fungi from soil.
Two efficient, semi-automatic elutriators for assaying soil samples for nematodes are described and show promise for monitoring populations of certain other soil microorganisms.
Structural and functional succession in the nematode fauna of a soil food web
Maintenance of adequate soil fertility in systems driven by organic input may require maintenance of food web structure and function as indicated by high levels of enrichment-opportunist bacterivore nematodes, which will require frequent supply of labile organic sources.
Agroecology: A Review from a Global-Change Perspective
This review by a multidisciplinary team maps key components and emerging connections within the intellectual landscape of agroecology. We attempt to extend and preview agroecology as a discipline in
A Method for Estimating Numbers of Eggs of Meloidogyne spp. in Soil.
A procedure for extracting eggs of Meloidogyne spp. from soil was developed by modifying and combining certain existing techniques. Egg masses were elutriated from the soft, gelatinous matrices of
Soil management to enhance bacterivore and fungivore nematode populations and their nitrogen mineralisation function
We tested the hypotheses that management of the soil food web in the fall would enhance grazing on bacteria and fungi by microbivorous nematodes in the spring, consequently increasing N availability
