Management strategies that deliberately include the native shrub Piliostigma reticulatum in Senegalese cropping systems result in soil functioning enhancement that benefits to the associated cereal. The objective of this work was to evaluate shrub effect on soil nematode communities. Soil samples were collected from an experimental design where pearl millet (Pennisetum glaucum) was cultivated alone or with P. reticulatum stands and mulch. Soil nematofauna characteristics were determined and compared with results from soil under pure shrub stands and from bare soil. The analysis of soil nematofauna, characterized by the abundance of different trophic groups and related indices (MI, maturity index; El and SI, enrichment and structure indices), allowed discrimination between treatments with or without shrub presence. The soil nematode community in millet cultivation was dominated by plant feeding nematodes, mainly from the Hoplolaimidae family, but their abundance decreased when P. reticulatum was associated to the cereal. The shrub also impacted other nematode trophic groups. The abundance of opportunistic bacterial feeders (mainly Cephalobidae) was increased in shrub treatments. Further research should explore consequences on cereal nutrition and nematicidal properties of P. reticulatum. specialized Piliostigma reticulatum Pennisetum glaucum Sahelian shrub Soil nematodes Trophic groups Ecological indices SENEGAL 074 082 076 57 35-41 2013 1164-5563 https://www.documentation.ird.fr/hor/fdi:010060461 10.1016/j.ejsobi.2013.04.003 1164-5563 [F B010060461] https://www.documentation.ird.fr/hor/fdi:010060461 https://www.documentation.ird.fr/intranet/publi/2013/08/010060461.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2013-09-03 2017-08-23 fdi:010060461 fre
