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 …

Conceptual parallels between physiological and behavioral forms of resistance to parasites
have led to the development of terminology like “the behavioral immune system” to refer to …

Biparental sex is widespread in nature, yet costly relative to uniparental reproduction. It is
generally unclear why self-fertilizing or asexual lineages do not readily invade outcrossing …

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 …

Animals have evolved specialized pathways to detect appropriate food sources and avoid
harmful ones. Caenorhabditis elegans can distinguish among the odors of various species …

Adaptation of replicate microbial communities frequently produces shared trajectories of
community composition and structure. However, divergent adaptation of individual …

Host–parasite interactions may often be subject to opposing evolutionary forces, which likely
influence the evolutionary trajectories of both partners. Natural selection and genetic drift are …

Host susceptibility to parasites can vary over space and time. Costs associated with the
maintenance of host defence are thought to account for a portion of this variation …

Host-parasite research often focuses on a single host life stage, yet different life stages may
exhibit different defenses. The nematode Caenorhabditis elegans has an alternate dispersal …

The ubiquity of outcrossing in plants and animals is difficult to explain given its costs relative
to self‐fertilization. Despite these costs, exposure to changing environmental conditions can …
