Parasites are generally thought of as being intimately tied to their hosts, yet many parasites produce free-living stages. This raises the question: what are parasites doing when they are not being parasitic? We studied the spatiotemporal dynamics of free-living infectious stages and asked whether these dynamics were correlated with infections in 2 focal host species. We used a com- mon and virulent bacterial parasite, Spirobacillus cienkowskii, which infects Daphnia spp. Densities of free…

Disease in freshwater zooplankton: what have we learned and where are we going?
The Daphnia –parasite model system offers a powerful tool to link anthropogenic changes to infectious diseases, including zoonotic diseases of significance to human health.
Global drivers of parasitism in freshwater plankton communities
A comparative analysis of parasitism in planktonic communities is presented, assembling data from a range of host and parasite taxa, habitat types, and geographic regions to suggest the prominent depth-prevalence relationship observed in studies on Daphnia in temperate lakes of North America is applicable to a wide range of aquatic habitats, hosts, and parasites.
A colorful killer: Daphnia infected with the bacterium Spirobacillus cienkowskii exhibit unexpected color variation.
When Elie Metchnikoff peered into a pond in the autumn of 1885, he saw something unusual. Among the many small, clear zooplankton that lived there a few 'distinguished themselves by their scarlet red.

The Population Dynamics of Microparasites and Their Invertebrate Hosts
Three simple models embodying the essentials of the dynamical interaction between invertebrate hosts and their directly transmitted microparasites suggest that the baculovirus and microsporidian infections of many temperate forest insects will tend to produce stable cycles in host abundance and in prevalence of infection, with periods in the range 5-12 years.
Selective Predation and Rapid Evolution Can Jointly Dampen Effects of Virulent Parasites on Daphnia Populations
The results show that understanding the outcomes of host‐parasite interactions in this Daphnia‐microparasite system may require consideration of ecological context and evolutionary processes and their interaction, and argue that two prominent features of this system, rapid evolution of host resistance to the parasite and selective predation on infected hosts, both decrease peak infection prevalence and can minimize decline in host density during epidemics.
Spatial heterogeneity of daphniid parasitism within lakes
Patterns suggest that nearshore offshore gradients, rather than local-scale interactions, could play a role in governing epidemiology of this open water host–parasite system.
Temporal, spatial, and between-host comparisons of patterns of parasitism in lake zooplankton.
This study demonstrates a method for parsing patterns of variation and covariation in infection prevalence data, providing greater insight into the relative importance of different underlying drivers of parasitism.
Haunted by the past: Evidence for dormant stage banks of microparasites and epibionts of Daphnia
The hypothesis that dormant stage banks remain infective for decades are explored, suggesting that long‐lasting spore banks for the disease dynamics and coevolution in the Daphnia‐microparasite system are discussed.

Ecosystem energetic implications of parasite and free-living biomass in three estuaries
It is shown that parasites have substantial biomass in these ecosystems and that the annual production of free-swimming trematode transmission stages was greater than the combined biomass of all quantified parasites and was also greater than bird biomass.
Infectious Disease and Species Coexistence: A Model of Lotka-Volterra Form
The model identifies three ingredients that must be assessed to predict the consequences of shared infectious disease for species coexistence: the intrinsic capacity for increase of each host; the per capita birth, death, and recovery rates of infected individuals; and the pattern of within- and cross-species infections.
Selective predators and their parasitized prey: Are epidemics in zooplankton under top‐down control?
It is suggested that parasitism in Daphnia populations may be seasonally restricted by fish predation, if driven largely by a reduction in predation.
Eating yourself sick: transmission of disease as a function of foraging ecology.
Foraging-based models for disease transmission rate based on broadly applicable components of feeding biology should broadly apply to systems in which hosts encounter parasites while eating, and will catalyse future integration of the roles of Daphnia as grazer and host.
