Genetic variation in defence against parasite infections is fundamental for host–parasite evolution. The overall level of defence of a host individual or population includes mechanisms that reduce parasite exposure (avoidance), establishment (resistance) or pathogenicity (tolerance). However, how these traits operate and evolve in concert is not well understood. Here, we investigated genetic variation in and associations between avoidance, resistance and tolerance in a natural host–parasite system. Replicated populations of Atlantic salmon (Salmo salar) and sea trout (an anadromous form of brown trout, Salmo trutta) were raised under common garden conditions and infected with the eye fluke Diplostomum pseudospathaceum. We demonstrate significant genetic variation in the defence traits across host populations and negative associations between the traits, with the most resistant populations showing the weakest avoidance and the lowest infection tolerance. These results are suggestive of trade-offs between different components of defence and possibly underlie the genetic variation in defence traits observed in the wild. Because the three defence mechanisms affect host–parasite evolution in profoundly different ways, we emphasize the importance of studying these traits in concert.

Variation in parasite resistance of Arctic charr, Salvelinus alpinus, between and within sympatric morphs
Karvonen, Anssi; Beck, Samantha V.; Skúlason, Skúli; Kristjánsson, Bjarni K.; Leblanc, Camille A. (Wiley-Blackwell, 2021)Genetic variation in resistance against parasite infections is a predominant feature in host–parasite systems. However, mechanisms maintaining genetic polymorphism in resistance in natural host populations are generally ... -
Cold water reduces the severity of parasite-inflicted damage : support for wintertime recuperation in aquatic hosts
Klemme, Ines; Hyvärinen, Pekka; Karvonen, Anssi (Springer, 2021)The reduction in host fitness caused by parasite infections (virulence) depends on infection intensity and the degree of damage caused per parasite. Environmental conditions can shape both virulence components, but in ... -
Host Developmental Stage Effects on Parasite Resistance and Tolerance
Klemme, Ines; Debes, Paul Vincent; Primmer, Craig Robert; Härkönen, Laura Sofia; Erkinaro, Jaakko; Hyvärinen, Pekka; Karvonen, Anssi (University of Chicago Press, 2022)Hosts can defend themselves against parasites either by preventing or limiting infections (resistance) or by limiting parasite-induced damage (tolerance). However, it remains underexplored how these defense types vary over ... -
Индивидуальность поведения рыб влияет на риск заражения паразитами [Personality influences risk of parasitism in fish]
Mikheev, V.N.; Pasternak, A.F.; Taskinen, J. (Rossiiskaya Akademiya Nauk / Russian Academy of Sciences, 2019)Influence of fish personality on infection rate is almost not studied. In the experiments on the young-of-the-year Oncorhynchus mykiss and cercariae of a trematode Diplostomum pseudospathaceum we tested the hypothesis that ... -
Connection between temperature, larval production, virulence and geographical distribution of Rhipidocotyle parasites infecting the duck mussel, Anodonta anatina
Choo, Jocelyn M. (University of Jyväskylä, 2015)In this thesis, two bucephalid trematode parasites Rhipidocotyle campanula and R. fennica, which use the same first (Anodonta anatina) and second intermediate (Rutilus rutilus) host were studied. The aim was to investigate ...
