abstract: Parasites can have important detrimental effects on host fitness, thereby influencing
their ecology and evolution. Hosts can, in turn, exert strong selective pressures on their
parasites, affecting eco-evolutionary dynamics. Although the reciprocal pressures that
hosts and parasites exert on each other have long been recognized, the mechanisms
are insufficiently understood. Here, we discuss the role of host cognition in host–parasite
eco-evolutionary dynamics. Theoretical advances have acknowledged the importance
of behavior in shaping these dynamics, but how and why host cognition should affect
and/or be affected by parasites is less clear. We propose three scenarios that may
create causal and non-causal links between cognition and the richness, prevalence
and intensity of parasites. First, host cognition may change the probability of exposure
to parasites, either increasing (e.g., altering the relationship with the environment via
innovative behaviors) or decreasing (e.g., influencing decision-making to avoid infected
conspecifics) exposure. Second, parasites may change host cognitive performance,
for example, by reducing host condition. Finally, host cognition and parasites can be
associated via common causal factors (e.g., shared molecular pathways), energetic
constraints generating trade-offs between cognition and immunocompetence, or trait
co-evolution with life history, ecological, or social strategies. The existence of such a
variety of non-mutually exclusive mechanisms suggests that host cognition has a great
potential to affect and be affected by parasites. However, it also implies that progress in
understanding these effects will only be possible if we distinguish between causal and
non-causal links.
