We assessed the effects of zinc and copper on freshwater monogenean ectoparasites (Discocotyle sagittata Leuckart) infecting juvenile Atlantic salmon (Salmo salar L.). Exposure to 47 μg/L zinc and 3 μg/L copper reduced survival and fecundity of adult D. sagittata, while egg hatching success was only reduced at high exposure concentrations (2704 μg/L zinc and 164 μg/L copper). Parasitized salmon had decreased plasma chloride, but this was negated in infected fish exposed to metals. No other… Expand
Hatchability and survival of oncomiracidia of Paradiplozoon ichthyoxanthon (Monogenea: Diplozoidae) exposed to aqueous aluminium
TLDR
Higher larval mortality rate in 120 μg/l exposure can be related to aluminium crossing the eggshell in the late stages and causing death of unhatched yet fully developed embryos, possibly due to changes in the permeability of the egg shell as embryos neared developmental completion. Expand
Temperature modulates the interaction between fungicide pollution and disease: evidence from a Daphnia-microparasitic yeast model
TLDR
It is shown that higher temperature generally increased the virulence of the parasite, with the hosts developing signs of infection earlier, reproducing less and dying at an earlier age. Expand
Interplay between fungicides and parasites: Tebuconazole, but not copper, suppresses infection in a Daphnia-Metschnikowia experimental model
TLDR
While copper and parasite effects were mostly independent, tebuconazole suppressed infection and the ecological consequences of such a suppression of infection include interferences in host population dynamics and diversity, as well as community structure and energy flow across the food web, which could upscale to ecosystem level given the important role of parasites. Expand
Can parasites adapt to pollutants? A multigenerational experiment with a Daphnia × Metschnikowia model system exposed to the fungicide tebuconazole.
TLDR
The microparasitic yeast M. bicuspidata did not reveal potential for rapid evolution to an anthropogenic selective pressure; instead, the long-term exposure to tebuconazole was hazardous to this non- target species, highlighting the potential environmental risks of azole fungicides on non-target parasitic fungi. Expand
Effects of chronic metal exposure on wild fish populations revealed by high-throughput cDNA sequencing
TLDR
The results suggest that this marked decrease in transcription levels could result from an impairment of bile acid metabolism by Cd and energy restriction but also from the recruitment of several genes involved in epigenetic modifications of histones and DNA that lead to gene silencing. Expand
Warming and pollutants interact to modulate octocoral immunity and shape disease outcomes.
TLDR
This work investigates how warming oceans and copper pollution affect host immunity and disease risk for two diseases of the abundant Caribbean octocoral, the sea fan Gorgonia ventalina and highlights the importance of immune mechanisms in environmentally-mediated disease outbreaks. Expand
Parasite community similarity in Athabasca River trout-perch (Percopsis omiscomaycus) varies with local-scale land use and sediment hydrocarbons, but not distance or linear gradients
TLDR
Variations in the abundance of these taxa and of overall community similarity were strongly correlated with sediment hydrocarbons as well as landscape use within 5 km of study sites, indicating that parasite populations and communities in this system were likely primarily influenced by habitat level and landscape-scale filters.

Combined effects of parasites and contaminants on animal health: parasites do matter.
The cumulative effects of multiple stressors are becoming a priority concern for ecotoxicologists, ecologists and conservation biologists working to understand threats to ecosystems and species. InExpand
Parasite responses to pollution: what we know and where we go in ‘Environmental Parasitology’
TLDR
The suitability of parasites as accumulation indicators and their possible application to demonstrate biological availability of pollutants; the role of parasite as pollutant sinks; the interaction between parasites and biomarkers focusing on combined effects of parasitism and pollution on the health of their hosts; and the use of parasitesAs indicators of contaminants and ecosystem health are addressed.

Effects of waterborne zinc on reproduction, survival and morphometrics of Gyrodactylus turnbulli (Monogenea) on guppies (Poecilia reticulata).
TLDR
Data clearly indicate that concentrations as low as 120 microg Zn/L are directly toxic to G. turnbulli, a viviparous monogenean infecting the skin and fins of the guppy, Poecilia reticulata. Expand

Environmental effects on transmission of Discocotyle sagittata (Monogenea): egg production and development.
TLDR
Egg production by the freshwater gill monogenean Discocotyle sagittata infecting rainbow trout was monitored at 5, 13 and 18 degrees C and viability declined at the highest and lowest temperatures; the implications for seasonal parasite transmission are discussed. Expand
Egg hatching in the monogenean gill parasite Discocotyle sagittata from the rainbow trout (Oncorhynchus mykiss)
TLDR
Field experiments confirmed that eggs exposed to the natural day/night cycle throughout development also demonstrated the precise hatching rhythm seen under controlled conditions, suggesting that hatching is a direct response to exogenous cues and not endogenously driven. Expand
Pollution toxicity to the transmission of larval digeneans through their molluscan hosts
TLDR
It is apparent from these studies that the influence of pollutants on digenean transmission is highly complex with much of the observed effects in the laboratory often masked by a complexity of other factors in the field. Expand

TLDR
The many ways in which toxic pollution may affect infections of metazoan parasites in freshwater fish are discussed, creating an urgent challenge for ecotoxicologists and fish parasitologists alike. Expand
Pollution and parasitism in aquatic animals: a meta-analysis of effect size.
TLDR
This meta-analysis represented a first attempt to consider the size of the effect of pollution on parasites, and highlighted the potential of susceptible parasite taxa, communities, and functional groups for use in the biological assessment of pollution. Expand

Only in RWW trout were ulcerations of the upper and lower jaw found, together with significantly more severe histological liver alterations and a higher lactatdehydrogenase (LDH) enzyme level in the blood. Expand

Data on parasitic infections in the western mosquitofish (Gambusia affinis), a fish that meets the criteria in two separate studies, illustrate the usefulness of that host as a model to indicate both healthy and detrimentally influenced environments. Expand
