Parasite Biology and Host Interactions

This study shows that VIE marking in guppies does not affect growth but increases parasite burden and transmission rates over time.

This study examines the impact of the nemertean parasite Carcinonemertes carcinophila on the reproductive output of Florida blue crabs, finding that body mass and embryo stage are stronger predictors than infestation status.

The paper shows host immune strategies affect parasite transmission timing and magnitude in a helminth parasite, with intermediate parasite burdens maximizing transmission potential.

This study identifies leeches and Neobenedenia girellae as potential vectors for Trypanosoma carassii spectrum and co-pathogenic bacteria in aquaculture, showing higher transmission efficiency via leeches in controlled experiments.

This study shows that parasite-parasite interactions affect spatial epidemiology, with within-host interactions having the strongest impact on prevalence and spread.

This study identifies helminth associations with gelatinous zooplankton across multiple seas, revealing their role as intermediate hosts and their impact on marine parasite biogeography.

This study examines how mixed-mode transmission affects parasite prevalence, finding that it can increase prevalence only under specific conditions involving different effects on host fitness.

The paper investigates immune variation in threespine stickleback populations by analyzing fibrosis responses to parasites and environmental factors.

The paper examines how thermal variability influences host-parasite defense strategies and infection dynamics, showing temperature variability can reduce infection prevalence but promote tolerance, increasing net prevalence.

This study shows that stickleback fish can transmit the parasite Pasteuria ramosa to its Daphnia host, contradicting the idea that predators reduce parasite prevalence.

This study links temperature and ecomorphology to blood pathogen incidence in neotropical amphibians, finding contrasting temperature responses and microhabitat influences on infection rates.

The paper shows that sublethal immune resistance can mimic tolerance in reaction-norm analysis, challenging the distinction between resistance and tolerance.

The paper tests how microbiome composition affects host survival in Daphnia magna infected with a fungal parasite, finding genotype- and life-stage-dependent effects.

The paper identifies genetic variants associated with host susceptibility to helminth and blood pathogens in Bank voles using GWAS, finding significant SNPs linked to non-classical immunity-related pathways.

The paper investigates how diet affects parasite transmission and epidemic dynamics in nematodes, finding that high-quality diets increase parasite abundance during epidemics despite similar fitness reductions across diets.

This study shows coinfections reduce temperature effects on host mortality in nematodes, but this effect weakens at extreme temperatures and with genetic variation.

This study uses ddPCR and Bayesian path analysis to link land-use changes to parasite dynamics in freshwater ecosystems, finding a positive correlation between deforestation and copepod density.

This study shows helminth infection increases susceptibility to gammaherpesvirus in wood mice, with anthelmintic treatment reducing viral infection and improved nutrition mitigating this effect.

This study examines the fitness consequences of parasite exposure versus infection in copepods, finding that exposure to sympatric parasites incurs lower fitness costs than exposure to allopatric parasites.

The paper analyzes how temperature and moisture affect helminth infections in bank voles over 17 years and multiple spatial scales, finding species-specific responses to climate variables.

The paper redescribes and provides the first molecular characterization of Ascarophis morrhuae, differentiates it from other North Atlantic Ascarophis species, and reviews previous records.

This study examines how parasitism, density, and resource availability interact to affect survival and fecundity in wild red deer across their lifespan.

The paper shows that food availability non-linearly affects host and pathogen traits in a Daphnia magna-Ordospora colligata system, with host fecundity increasing and virulence peaking at intermediate resource levels.

This study meta-analyzes 775 effect sizes from 124 studies to show elevated temperatures increase parasitism in many host-parasite systems, with varied responses across taxa.

This study investigates how heatwave duration and predictability affect host-parasite interactions under different mean temperature conditions, finding parasite-specific responses to thermal variability.

The paper shows that younger hosts have lower parasite prevalence and that dispersing juveniles are less infected during early epidemic stages in C. elegans.

This study shows that food supplementation reduces nematode abundance super-shedding in wild voles but not infection likelihood or intensity, and identifies age-related fitness impacts of nematode infection.

This study shows resource supplementation affects parasite infection dynamics and host behavior in wild wood mice, with mixed effects across 12 parasite taxa.
