Novel parasites can have wide-ranging impacts, not only on host
populations, but also on the resident parasite community. Historically,
impacts of novel parasites have been assessed by examining pairwise
interactions between parasite species. However, parasite communities are
complex networks of interacting species. Here, we used multivariate
taxonomic and trait-based approaches to determine how parasite community
composition changed when African buffalo (Syncerus caffer) acquired an
emerging disease, bovine tuberculosis (BTB). Both taxonomic and functional
parasite richness increased significantly in animals that acquired BTB
than in those that did not. Thus, the presence of BTB seems to catalyze
extraordinary shifts in community composition. There were, however, no
differences in overall parasite taxonomic composition between infected and
uninfected individuals. The trait-based analysis revealed that
direct-transmitted, quickly replicating parasites increased following BTB
infection. This study demonstrates that trait-based approaches provide
novel insight for understanding parasite community dynamics in the context
of emerging infections. Parasite Prevalence Data
