dc.description.abstract | The resource quality of the host has been shown to affect parasite transmission
success, prevalence, and virulence. Seasonal availability of environmental nutrients alters
density and stoichiometric quality (carbon–nutrient ratios) of both producers and consumers,
suggesting that nutrient availability may drive fluctuations in parasite prevalence patterns
observed in nature. We examined the interactions between the population dynamics of a
keystone herbivore, Daphnia, and its parasites, and their associations with water nutrient
concentrations, resource quantity and quality, and other environmental variables (temperature,
pH, oxygen concentration) in a small lake, using general linear models. We found that
the prevalence of two gut endoparasites was positively related to food source and quality as
well as nitrogen content of Daphnia, whereas the prevalence of an epibiont and overall parasite
species richness was negatively related to phosphorus content of Daphnia. When only
endoparasite species richness was considered, no connections to nutrients were found. Daphnia
density was not connected to parasites, but we found interactions between Daphnia fecundity
and parasite prevalence. Overall, our results suggest that environmental nutrient concentrations
and stoichiometric quality of the host have the potential to affect seasonality in parasite
epidemics, but the connections between environmental carbon : nutrient ratios and parasite
prevalence patterns are diverse and species specific. | fi |
