Background: Co-infections of multiple parasite species in hosts may lead to interspecific associations and subsequently shape the structure of a parasite community. However, few studies have focused on these associations in highly abundant parasite species or, in particular, investigated how the associations develop with time in hosts exposed to co-infecting parasite species for the first time. We investigated metacercarial establishment and interspecific associations in the trematodes Ichthyocotylurus variegatus and I. pileatus co-infecting three age cohorts of young perch (Perca fluviatilis). Results: We found that the timing of transmission of the two Ichthyocotylurus species was very similar, but they showed differences in metacercarial development essentially so that the metacercariae of I. pileatus became encapsulated faster. Correlations between the abundances of the species were significantly positive after the first summer of host life and also within the main site of infection, the swim bladder. High or low abundances of both parasite species were also more frequent in the same host individuals than expected by chance, independently of host age or size. However, the highest abundances of the species were nevertheless observed in different host individuals and this pattern was consistent in all age cohorts. Conclusions: The results suggest similar temporal patterns of transmission, non-random establishment, and facilitative rather than competitive associations between the parasite species independently of the age of the infracommunities. However, we suggest that spatial differences in exposure are most likely responsible for the segregation of the parasite species observed in the few most heavily infected hosts. Regardless of the underlying mechanism, the result suggests that between-species associations should be interpreted with caution along with detailed examination of the parasite distribution among host individuals. ...

Parasite transmission in aquatic ecosystems under temperature change : effects of host activity and elimination of parasite larvae by filter-feeders Gopko, Misha; Mironova, Ekaterina; Pasternak, Anna; Mikheev, Victor; Taskinen, Jouni (Wiley-Blackwell, 2020)A moderate raise in temperature was suggested to enhance the impact of parasites on aquatic ecosystems. Under higher temperatures, poikilothermic animals (e.g. fish) increase their activity, which can result in a more ...
Spatiotemporal and gender-specific parasitism in two species of gobiid fish Karvonen, Anssi; Lindström, Kai (John Wiley & Sons Ltd., 2018)Parasitism is considered a major selective force in natural host populations. Infections can decrease host condition and vigour, and potentially influence, for example, host population dynamics and behavior such as mate ...
Divergent parasite infections in sympatric cichlid species in Lake Victoria Karvonen, Anssi; Wagner, Catherine E.; Selz, Oliver M.; Seehausen, Ole (Wiley-Blackwell Publishing Ltd., 2018)Parasitism has been proposed as a factor in host speciation, as an agent affecting coexistence of host species in species‐rich communities and as a driver of post‐speciation diversification. Young adaptive radiations of ...
Differences in parasite community composition support ecological differentiation in a freshwater gadoid fish Karvonen, Anssi; Horppila, Petteri; Kuitunen, Jere; Miettinen, Miikka; Ryynänen, Lauri; Marjomäki, Timo J. (John Wiley & Sons, 2022)Several northern freshwater fishes have gone through rapid adaptive radiation after the last glacial period, resulting in new species or intraspecific morphs with distinct life histories. Parasite infections can promote ...
