Competent Non‐Native Alternative Host Reduces Infection Success in a Generalist Parasite
Ecology and Evolution, Volume 16, Issue 6, June 2026.In this study, we experimentally assessed how the addition of a non‐native alternative host affects the infection success of the larval generalist trematode, Diplostomum pseudospathaceum, in fish intermediate hosts. Our results demonstrate that the presence of alternative hosts, especially the non‐native ones, can reduce parasite transmission through ...
