Evidence is accumulating that plant–herbivore interactions vary spatiotemporally at scales of several decades and hundreds of kilometers and that this drives the evolution of plant defense within a species. Here, we present a general review of recent examples with the aim of outlining an empirical framework for understanding the evolutionary dynamics of anti-herbivore defenses. First, we review the mechanisms shaping and maintaining variation in plant defense by focusing on two spatial scales, <i>i.e</i>., <i>within</i> and <i>among</i> populations. We review how biotic and abiotic factors cause divergent selection <i>among</i> populations and thereby shape geographic variation in plant defense. <i>Within</i> a plant population, we focus on how an apparent herbivore-mediated interaction maintains genetic variation in anti-herbivore defense. Then, we outline intraspecific evolutionary processes and patterns (<i>i.e</i>., microevolution) in plant defense by connecting the two spatial scales in terms of apparent competition. We also discuss whether major hypotheses explaining interspecific patterns of plant defense can explain microevolution and whether microevolution in plant defense links to interspecific variation via speciation. These recent findings suggest that microevolution in plant defense contributes to global and phylogenetic patterns (macroevolution) in plant defense.Evidence is accumulating that plant–herbivore interactions vary spatiotemporally at scales of several decades and hundreds of kilometers and that this drives the evolution of plant defense within a species.
