Evolution and ecology of parasite avoidance
AK Gibson, CR Amoroso - Annual review of ecology, evolution …, 2022 - annualreviews.org
Parasite avoidance is a host defense that reduces an individual's contact rate with parasites.
We investigate avoidance as a primary driver of variation among individuals in their risk of …

[HTML][HTML] An integrated landscape of fear and disgust: the evolution of avoidance behaviors amidst a myriad of natural enemies
JF Doherty, B Ruehle - Frontiers in Ecology and Evolution, 2020 - frontiersin.org
Fear of natural enemies in non-human animals is a concept dating back to the time of
Darwin. Now recognized as a non-consumptive effect, the ecological and evolutionary …

Genetic variation in parasite avoidance, yet no evidence for constitutive fitness costs
CR Amoroso, LL Shepard, AK Gibson - Evolution, 2024 - academic.oup.com

Age structure eliminates the impact of coinfection on epidemic dynamics in a freshwater zooplankton system
PA Clay, S Gattis, J Garcia… - The American …, 2023 - journals.uchicago.edu
Parasites often coinfect host populations and, by interacting within hosts, might change the
trajectory of multiparasite epidemics. However, host-parasite interactions often change with …

Virulent disease epidemics can increase host density by depressing foraging of hosts
RM Penczykowski, MS Shocket… - The American …, 2022 - journals.uchicago.edu
All else equal, parasites that harm host fitness should depress densities of their hosts.
However, parasites that alter host traits may increase host density via indirect ecological …

Timescale reverses the relationship between host density and infection risk
TE Stewart Merrill, CE Cáceres… - … of the Royal …, 2022 - royalsocietypublishing.org
Host density shapes infection risk through two opposing phenomena. First, when infective
stages are subdivided among multiple hosts, greater host densities decrease infection risk …

Natural variation in host feeding behaviors impacts host disease and pathogen transmission potential
AC Pfenning‐Butterworth, RE Vetter… - Ecology and …, 2023 - Wiley Online Library
Animals ranging from mosquitoes to humans often vary their feeding behavior when infected
or merely exposed to pathogens. These so‐called “sickness behaviors” are part of the innate …

A high‐throughput method to quantify feeding rates in aquatic organisms: A case study with Daphnia
JL Hite, AC Pfenning‐Butterworth… - Ecology and …, 2020 - Wiley Online Library
Food ingestion is one of the most basic features of all organisms. However, obtaining
precise—and high‐throughput—estimates of feeding rates remains challenging, particularly …

Dose relationships can exacerbate, mute, or reverse the impact of heterospecific host density on infection prevalence
The likelihood an individual becomes infected depends on the community in which it is
embedded. For environmentally transmitted parasites, host community composition can alter …

“Resistance Is Futile”: Weaker Selection for Resistance by Abundant Parasites Increases Prevalence and Depresses Host Density
Abstract Theory often predicts that host populations should evolve greater resistance when
parasites become abundant. Furthermore, that evolutionary response could ameliorate …
