Mechanisms by which predators mediate host–parasite interactions in aquatic systems

LK Lopez, MA Duffy - Trends in Parasitology, 2021 - cell.com
It is often assumed that predators reduce disease prevalence and transmission by lowering
prey population density and/or by selectively feeding on infected individuals. However …

Spatial compartmentalization: a nonlethal predator mechanism to reduce parasite transmission between prey species

LGR Oliveira-Santos, SA Moore, WJ Severud… - Science …, 2021 - science.org
Predators can modulate disease transmission within prey populations by influencing prey
demography and behavior. Predator-prey dynamics can involve multiple species in …

Ranavirus ecology: from individual infections to population epidemiology to community impacts

JL Brunner, A Storfer, EH Le Sage, TWJ Garner… - … : Emerging Pathogens of …, 2024 - Springer
While ranaviruses were initially a focus of scientific study primarily among virologists, the
continued and growing interest in them stems largely from their impacts on host populations …

A healthy but depleted herd: Predators decrease prey disease and density

LK Lopez, MH Cortez, TS DeBlieux, IA Menel… - Ecology, 2023 - Wiley Online Library
The healthy herds hypothesis proposes that predators can reduce parasite prevalence and
thereby increase the density of their prey. However, evidence for such predator‐driven …

Predation shifts coevolution toward higher host contact rate and parasite virulence

JC Walsman, CE Cressler - Proceedings of the Royal …, 2022 - royalsocietypublishing.org
Hosts can avoid parasites (and pathogens) by reducing social contact, but such isolation
may carry costs, eg increased vulnerability to predators. Thus, many predator–host–parasite …

Dynamic trait distribution as a source for shifts in interaction strength and population density

Z Jackson, BK Xue - The American Naturalist, 2024 - journals.uchicago.edu
Intraspecific trait variation has been increasingly recognized as an important factor in
determining species interactions and diversity. Eco-evolutionary models have studied the …

D Duneau, N Buchon - Animal Behaviour, 2022 - Elsevier
Highlights•Chronic infection of Drosophila did not significantly affect the risk of

Spatially heterogeneous eco-epidemic model: Stabilizing role of non-local disease transmission

S Dey, DK Das, S Ghorai, M Banerjee - Communications in Nonlinear …, 2024 - Elsevier
Interaction between prey and predator in the presence of an infectious pathogen is the main
focus of this article. A non-local transmission, that encompasses the possibility of acquiring …

Context-dependent consumptive and non-consumptive predator effects of omnivorous tadpoles based on body size and habitat shading

BP Parlato, CL Mott - Hydrobiologia, 2024 - Springer
Despite previous treatment as herbivores, largely omnivorous tadpoles may exhibit both
consumptive (CEs) and non-consumptive effects (NCEs), but the roles of additional biotic …

Pathogens and predators: examining the separate and combined effects of natural enemies on assemblage structure

TS DeBlieux, JT Hoverman - Oecologia, 2022 - Springer
Natural enemy ecology strives to unify predator–prey and host–pathogen interactions under
a common framework to gain insights into community-and ecosystem-level processes. To …
