Microbiomes have profound effects on host fitness, yet we struggle to understand the
implications for host ecology. Microbiome influence on host ecology has been investigated …

In most species, variation in age among individuals is the strongest and most visible form of
phenotypic variation. Individual-level age effects on disease traits, caused by differences in …

Climatic warming will likely have idiosyncratic impacts on infectious diseases, causing some
to increase while others decrease or shift geographically. A mechanistic framework could …

Co-infections of hosts by multiple pathogen species are ubiquitous, but predicting their
impact on disease remains challenging. Interactions between co-infecting pathogens within …

What drives the evolution of parasite life-history traits? Recent studies suggest that linking
within-and between-host processes can provide key insight into both disease dynamics and …

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

Human activities simultaneously alter nutrient levels, habitat structure, and levels of
parasitism. These activities likely have individual and joint impacts on food webs …

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

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 …

A common assumption is that pathogens more readily destabilize their host populations,
leading to an elevated risk of driving both the host and pathogen to extinction. This logic …
