Parasitic organisms can affect ecosystems by driving population dynamics of the hosts and influencing community interactions. The life history of the host can determine the relationship with its parasites. Reproductive effort and age of the host are two life history aspects often used to explain parasitic infection. In this study, we examined helminth parasite assemblages in two cyprinids with contrasting reproductive strategies, Cyprinella venusta (crevice spawners) and Notropis volucellus…

Patterns of the parasite communities in a fish assemblage of a river in the Brazilian Amazon region
Fish assemblage had few species of helminth that were specialist endoparasites, while many were parasites at the larval stage, infecting intermediate and paratenic hosts, lends supports to the notion that the feeding habits of the host species are a significant factor in determining the endopartasites fauna.

The diversity of nematodes that use P. nattereri as a host indicates the important role of this fish species in the maintenance of these six nematode Species in the lowland lakes of Central Amazonia.
No impact of a presumed manipulative parasite on the responses and susceptibility of fish to simulated predation
The manipulation of a host organism by its parasites is a widespread phenomenon that varies in its expression across taxa and interac‐ tions, from helminths that cause corals to swell and turn pink


Associations between fish reproductive cycle and the dynamics of metazoan parasite infection
The results suggest that stone loach females are more susceptible to parasite infection in periods of higher reproductive investment, probably induced by increasing fish hormone levels in the spring.
Parasite diversity and coinfection determine pathogen infection success and host fitness
The field data revealed the highly nested structure of parasite assemblages, with virulent species generally occupying basal positions, suggesting that increases in parasite richness and antagonism in nature will decrease virulent infections.

Host Partitioning by Parasites in an Intertidal Crustacean Community
Mapping the flow of parasites throughout the major crustacean species, identifying hosts that play the most important transmission role for each parasite, and assessing the impact of parasitism on host populations find the different parasite species make different use of available crustACEan intermediate hosts and possibly contribute to intertidal community structure.
The stickleback–Schistocephalus host–parasite system as a model for understanding the effect of a macroparasite on host reproduction
Using the trophic transmitted Schistocephalus as a model, the suite of traits expressed in hosts of trophically transmitted parasites should be systematically investigated to develop a complete understanding of the system.
Are the Immunocompetence and the Presence of Metazoan Parasites in Cyprinid Fish Affected by Reproductive Efforts of Cyprinid Fish?
It is found that reproductive investments in fish play an important role for energy allocation into somatic condition, immunity, and reproduction and may be associated with higher susceptibility to the metazoan parasites.
Importance of parasites and their life cycle characteristics in determining the structure of a large marine food web
The respective effect of individual parasite species was roughly proportional to the number of host species they affected, and thus the life cycle characteristics of parasites determine to a large extent their impact on food web structure.
Parasitism, life history traits and immune defence in cyprinid fish from Central Europe
The comparative analyses using cyprinid fish species demonstrated that natural mortality could be considered as a factor contributing to the variability of parasite species richness and moreover, parasite species benefit from long-lived fish.
Variation in the intraspecific relationship between fish length and intensity of parasitic infection: biological and statistical causes.
In a meta-analysis, the overall mean correlation between fish length and the intensity of parasitic infections derived from 76 different host-parasite species was positive but weak and
Diversity and disease: community structure drives parasite transmission and host fitness.
It is suggested that interspecific variation in parasite resistance can inhibit parasite transmission in multi-species communities, reducing infection and pathology in sensitive hosts.
