While significant attention has been devoted to describing the diversity of host manipulation among parasite clades, and testing the adaptive value of phenotypic traits that can be manipulated, there is increasing evidence that variation exists in the frequency and intensity of the changes displayed by parasitized individuals within single host-manipulative parasite systems. Such variability occurs within individuals, between individuals of a same population, and across populations. Here we review the non-genetic (i.e. environmental) and genetic causes of variability in host behaviour manipulation, discuss its evolutionary significance, and propose directions for further researches. specialized Coevolution Genetic effect Environmental effect Local adaptation Phenotypic plasticity Acanthocephalans Cestodes Trematodes 052 11 2 262-269 2011 1567-1348 https://www.documentation.ird.fr/hor/fdi:010053446 10.1016/j.meegid.2010.12.013 1567-1348 [F B010053446] https://www.documentation.ird.fr/hor/fdi:010053446 https://www.documentation.ird.fr/intranet/publi/2011/04/010053446.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2011-05-02 2017-08-23 fdi:010053446 fre
