Summary
Introduction
Biological invasions result in a wide range of novel ecological and evolutionary interactions with native community members. Invaders may be predators or competitors, with direct negative impacts on native taxa, and they may be prey or mutualists, which could have positive effects on native taxa. In addition to these initial direct effects, as invading species become integrated into native communities, they begin to interact both directly and indirectly with a multitude of native taxa in the invaded community. While the direct effects of biological invasions on natives are well appreciated, the indirect effects of biological invasions remain relatively unstudied (White et al. 2006), especially from an evolutionary perspective. However, indirect effects are likely common, can be strong, and may impact an even wider array of community members than the initial direct effects resulting from the invasion.
In this chapter, I first briefly discuss: (1) the evidence for evolutionary changes in both natives and invaders during the invasion process and (2) the many potential and documented indirect effects of invaders on natives. I then combine these two themes to address the main thesis: how evolutionary changes in both natives and invaders during the invasion process can alter interactions with additional community members (i.e. ‘evolutionary indirect effects’). While specific tests for evolutionary indirect effects in the context of biological invasions are still rare, I present a series of examples linking evolutionary change and strong indirect effects to illustrate the possibility for important evolutionary indirect effects. I conclude by discussing open questions and experimental designs that could explicitly test the importance of evolutionary indirect effects to natural communities and the study of biological invasions.
