Unravelling the beta diversity of plant-parasitic nematodes associated with cultivated olive in southern Spain

Trabajo presentado en el 15th Congress of the Mediterranean Phytopathological Union (Plant health sistaining Mediterranean ecosystems), celebrado en Córdoba (España) del 20 al 23 de junio de 2017.Olive trees host many plant-parasitic nematodes (PPNs). Understanding the factors that maintain biodiversity in communities depends on identification of diversity. We investigated the effects of environmental conditions, soil properties, agronomic management practices and spatial structure, on the variation of species community composition (β-diversity) and species richness of PPNs infesting rhizosphere soil from 376 commercial olive orchards widely distributed in Andalusia, southern Spain.This research was supported by the Project AGL-2012-37521 from `Ministerio de Economía y Competitividad’ of Spain, Project P12-AGR-1486 from `Consejería de Economía, Innovación y Ciencia’ of Junta de Andalucía, and FEDER financial support from the European Union.N
