Earlier parasite arrival reduces the repeatability of host adaptive radiation

Although parasites are known to have various effects on their hosts, we know little about their role in the assembly of diversifying host populations. Using an experimental bacterium (Pseudomonas fluorescens SBW25)-bacteriophage (ϕ2) system, we show that earlier parasite arrival significantly reduce...

description Although parasites are known to have various effects on their hosts, we know little about their role in the assembly of diversifying host populations. Using an experimental bacterium (Pseudomonas fluorescens SBW25)-bacteriophage (ϕ2) system, we show that earlier parasite arrival significantly reduced the repeatability of host diversification. Earlier parasite arrival amplified the priority effects associated with the stochastic emergence of novel SBW25 phenotypes, translating into greater historical contingency in SBW25 diversification. Our results highlight the important role of parasite-host interactions in driving host adaptive radiation.
