| 英文摘要: | Ecological speciation appears to contribute to the diversification of insect herbivores and other parasites, which together comprise a major component of Earth's biodiversity. Host shifts are likely an important step in ecological speciation, and understanding how such shifts occur is critical to forming and testing hypotheses explaining parasite diversity. In this article, I argue that phenotypic variation in hosts arising from environmental variation (phenotypic plasticity) can promote shifts in parasites by bridging both spatiotemporal and phenotypic gaps between ancestral and novel hosts. This hypothesis, which I call the 'plastic-bridge hypothesis', is conceptually distinct from those invoking genetic variation in bridging these gaps. I describe the mechanistic basis of plastic bridges, review circumstantial evidence in support of the hypothesis and suggest strategies for testing it. I use herbivorous insects and their host plants as a model, but the proposed ideas apply to any system fitting a broad definition of a host-parasite relationship. The plastic-bridge perspective suggests that parasite diversity is not only due to divergent selection provided by hosts, but also to the intraspecific variation that facilitates shifts between them. This view is timely, as biological invasion and range shifts associated with climate change foster novel interactions between parasites and hosts. Copyright © 2016 John Wiley & Sons Ltd/CNRS. |
