In contrast, widespread host species that live in high density are exposed to a wide range of parasite species that may affect drastically the population dynamics of these carnivores, suggesting that macroparasites may regulate them at least locally. Interestingly, Allee effects and parasitism have several features in common that are of interest when studying population dynamics in conservation biology (Deredec 2005) . Invasive host species have another advantage if they have invested in strong immune defences in their natural range, which may then subsequently confer a better capacity to control parasites that they may acquire in the introduced habitat. ./cache/cord-017819-85x0juiw.txt ./txt/cord-017819-85x0juiw.txt
