Phenotypic alterations in parasitised hosts modify host population ecology, apparent competition processes, food web structure and energy and nutrient flow between habitats, as well as favouring habitat creation. As is usually the case in ecology, these phenomena can be greatly amplified by a series of secondary consequences (cascade effects). Here we review the ecological relevance of manipulative parasites in ecosystems and propose directions for further research. specialized 052 020 24 1 41-48 2009 0169-5347 https://www.documentation.ird.fr/hor/fdi:010046078 10.1016/j.tree.2008.08.007 0169-5347 [F B010046078] https://www.documentation.ird.fr/hor/fdi:010046078 https://www.documentation.ird.fr/intranet/publi/2009/compl1/010046078.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2009-07-08 2017-08-23 fdi:010046078 fre
