TL;DR: This work describes a wealth of information on the induction of various plant biochemical responses to environmental stimuli but found a limited body of literature on the reversibility of induced biochemical responses.

TL;DR: Three approaches to examine allelopathy as a mechanism for invasion are discussed and a data set for congeneric Lantana and Prosopis is presented to illustrate how the congeneric approach can be used, and experimentally how traditional and bio-geographic approaches can be integrated to shed light on allelopathic in exotic plant invasions are demonstrated.

TL;DR: It is hypothesized that Centaurea maculosa experiences strong directional selection on novel competitive and defense traits in its new range, suggesting that the evolution of increased competitive ability may not always be driven by physiological trade-offs between the allocation of energy or resources to growth or to defense.

TL;DR: A synthesis of separate lines of inquiry is a step towards understanding the evolutionary importance of interactions among plants, and suggests that the evolutionary consequences of interactions contribute to communities that are more than assemblages of independent populations.

TL;DR: Comparisons of mutualistic and antagonistic biota in soils collected in the native, expanded, and invasive range of the black locust tree, Robinia pseudoacacia, suggest that important regional evolutionary relationships may occur among plants and soilBiota, and that net effects of soil biota may affect invasion, but in ways that are not easily explained by studying isolated components of the soil biOTA.
