Phenotypic plasticity is nearly universal among organisms, and evidence indicates that plasticity can exhibit additive genetic variation and respond to selection. These findings have important implications for our understanding of how plasticity may be constrained and how its mechanistic structure may affect its evolution. Many life history trade-offs may(More)
Behavioral plasticity can occur on multiple timescales, from traits fixed during development to traits that remain plastic throughout an individual’s lifetime. Because mate choice is a key factor in determining selection on male ornaments, understanding the timescale of plasticity in female choice behavior is critical to understanding how this plasticity(More)
Please cite this article in press as: Zuk, M., e dx.doi.org/10.1016/j.anbehav.2014.02.032 It may seem as if behaviour is so plastic that it would not foster the establishment of a genetically determined trait, but under some circumstances, it can greatly influence whether a novel trait, such as a new morphology, spreads in a population. If the behaviours(More)
Alternative reproductive tactics may arise when natural enemies use sexual signals to locate the signaler. In field crickets, elevated costs to male calling due to acoustically orienting parasitoid flies create opportunity for an alternative tactic, satellite behavior, where noncalling males intercept females attracted to callers. Although the(More)
