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 …

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 …

Behavioral avoidance of parasites is a widespread strategy among animal hosts and in
human public health. Avoidance has repercussions for both individual and population-level …

Parasites often coinfect host populations and, by interacting within hosts, might change the
trajectory of multiparasite epidemics. However, host-parasite interactions often change with …

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 …

Host density shapes infection risk through two opposing phenomena. First, when infective
stages are subdivided among multiple hosts, greater host densities decrease infection risk …

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 …

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 …

The likelihood an individual becomes infected depends on the community in which it is
embedded. For environmentally transmitted parasites, host community composition can alter …

Abstract Theory often predicts that host populations should evolve greater resistance when
parasites become abundant. Furthermore, that evolutionary response could ameliorate …
