Increased resource availability can promote invasion by exotic plants, raising concerns over the potential effects of global increases in the deposition of nitrogen (N). It is poorly understood why increased N favors exotics over natives. Fast growth

The impact of exotic species on native organisms is widely acknowledged, but poorly understood. Very few studies have empirically investigated how invading plants may alter delicate ecological interactions among resident species in the invaded range.

Concern over exotic invasions is fueled in part by the observation that some exotic species appear to be more abundant and have stronger impacts on other species in their non-native ranges than in their native ranges. Past studies have addressed biog

Summary 1. Increased resource availability and resource pulses often promote invasion by exotic invasive plants, but the relative importance of increased resource supply for invaders with different life histories is likely to vary. It is also unclear

A central hypothesis in ecology is that plant life history evolution is constrained by funda- mental ''compromises between the conflicting selec- tion pressures resulting from particular combinations of competition, stress, and disturbance'', with st

Summary 1. Exotic invasive plants can have strong effects on native communities. Centaurea maculosa , a forb that is native to Eurasia, has created near-monocultures in many parts of its invaded range in western North America and produces the root ex

Recent studies suggest that the invasive success of Centaurea maculosa may be related to its stronger allelopathic effects on native North American species than on related European species, one component of the "novel weapons" hypothesis. Other resea

Centaurea maculosa Lam. is a noxious weed in western North America that produces a phytotoxin, (±)-catechin, which is thought to contribute to its invasiveness. Areas invaded by C. maculosa often result in monocultures of the weed, however; in some

Summary 1 Plant allelopathic compounds may have other roles than interspecific interference. We investigated whether ( ± )-catechin, a phytotoxin exuded from the roots of the exotic invader Centaurea maculosa (spotted knapweed), is also one of the f
