Why do infectious diseases erupt in some host populations and not others? This question
has spawned independent fields of research in evolution, ecology, public health, agriculture …

Pathogens continue to emerge from increased contact with novel host species. Whilst these
hosts can represent distinct environments for pathogens, the impacts of host genetic …

It is assumed that host genetic variability for susceptibility to infection conditions virus
evolution. Differences in host susceptibility can drive a virus to diversify into strains that track …

Virulence, the harm to hosts caused by parasite infection, can be selected for by several
ecological factors acting synergistically or antagonistically. Here, we focus on the potential …

Parasites, including pathogens, can adapt to better exploit their hosts on many scales,
ranging from within an infection of a single individual to series of infections spanning …

Virulence, the degree to which a pathogen harms its host, is an important but poorly
understood aspect of host-pathogen interactions. Virulence is not static, instead depending …

Although parasite-mediated selection is a major driver of host evolution, its influence on
genetic variation for parasite resistance is not yet well understood. We monitored resistance …

The giant liver fluke (Fascioloides magna) is an invasive parasite found permanently in three
foci in Europe. The fluke has an indirect life cycle involving a final and an intermediate host …

Natural events over time, and human interventions, influence the genetic structure of
species. The red deer (Cervus elaphus) is widely distributed in Europe, with a large‐scale …

Pairwise host–parasite relationships are typically embedded in broader networks of
ecological interactions, which have the potential to shape parasite evolutionary trajectories …
