The primary hypothesis for the astonishing success of many exotics as community invaders relative to their importance in their native communities is that they have escaped the natural enemies that control their population growth – the `natural enemies hypothesis'. However, the frequent failure of introduced biocontrols, weak consumer effects on the growth and reproduction of some invaders, and the lack of consistent strong top-down regulation in many natural ecological systems indicate that… Expand

Figures from this paper

Allelopathic effect of a native species on a major plant invader in Europe
TLDR
Native species use allelopathy as a biotic containment mechanism against the naturalization of invasive species, testing the impact of the native species Sambucus ebulus on the colonization of propagules of the invasive species Fallopia x bohemica. Expand
Allelopathy of a native grassland community as a potential mechanism of resistance against invasion by introduced plants
TLDR
Although allelopathy of native plant communities might increase their resistance against introduced plants, there was no evidence that tolerance to allelopathic ofnative plant communities contributes to the degree of invasiveness of introduced plants. Expand
Allelopathy and plant invasions: traditional, congeneric, and bio-geographical approaches
TLDR
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. Expand
Allelopathy as a mechanism for the invasion of Typha angustifolia
TLDR
The allelopathic effects of T.angustifolia on a North American native wetland plant and its production of root biochemicals that appear to differ from those produced by a native congener are consistent with the possibility that T. angust ifolia may use a novel allelochemical in its invasion of North American wetlands. Expand
Allelopathic Effects of Native Versus Invasive Plants on One Major Invader
TLDR
The autoallelopathy of L. hexapetala could explain its invasiveness and an “invasional meltdown” of the two invasive plant species Myriophyllum aquaticum and L. peploides could favor the establishment of invasive species. Expand
Allelopathic invasion of alien plant species in India and their management strategies: A review
TLDR
Integrated management with the participation of native people and proper land management have been proved beneficial in controlling the invasion of weeds in India. Expand
Do allelopathic compounds in invasive Solidago canadensis s.l. restrain the native European flora
TLDR
Seven competing native European plant species were more competitive against the invasive species in soils with activated carbon than without, supporting the allelopathy hypothesis and suggesting lower investment of invasive plants into secondary compounds, possibly because of a higher susceptibility of plant competitors in the invasive range to these substances. Expand
Understanding invasions: the rise and fall of diffuse knapweed (Centaurea diffusa) in North America
TLDR
Control of this invasive species by insect herbivory now appears to have been achieved in widely separated ecosystems in North America. Expand
Relative allelopathic potential of invasive plant species in a young disturbed woodland1
TLDR
Most species, particularly invasive shrubs, did not exhibit sufficient allelopathic potential to suggest allelopathy would occur in the field and warrant additional study in theField. Expand
Allelopathy and resource competition: the effects of Phragmites australis invasion in plant communities
TLDR
The results demonstrated that plant–plant interference is the combined effect of allelopathy and resource competition with many other factors but this experimental design, target-neighbor mixed-culture in combination of plant grown at varying densities with varying level of phytotoxins, mono-culture can successfully separate allelopathic effects from competition.

Fluctuating resources in plant communities: a general theory of invasibility
TLDR
It is concluded that the elusive nature of the invasion process arises from the fact that it depends upon conditions of resource enrichment or release that occur only intermittently and, to result in invasion, must coincide with availability of invading propagules. Expand
Invasive plants versus their new and old neighbors: a mechanism for exotic invasion.
TLDR
It is found that Centaurea diffusa, a noxious weed in North America, has much stronger negative effects on grass species from North America than on closely relatedgrass species from communities to which CentAurea is native. Expand
When do herbivores affect plant invasion? Evidence for the natural enemies and biotic resistance hypotheses
TLDR
A review of the evidence for both the natural enemies hypothesis and the biotic resistance hypothesis reveals that: 1) introduced plants can attract a diverse assemblage of native herbivores and that 2) native Herbivores can reduce introduced plant growth, seed set and survival. Expand
An ecosystem‐level perspective of allelopathy
TLDR
It is argued that the concept of allelopathy is more appropriately applied at the ecosystem‐level, rather than the traditional population/community level of resolution, and two contrasting examples of how invasive plant species with allelopathic potential may alter ecosystem properties through the production of secondary metabolites are illustrated.

BIOTIC INVASIONS: CAUSES, EPIDEMIOLOGY, GLOBAL CONSEQUENCES, AND CONTROL
TLDR
Given their current scale, biotic invasions have taken their place alongside human-driven atmospheric and oceanic alterations as major agents of global change and left unchecked, they will influence these other forces in profound but still unpredictable ways. Expand
Modeling invasive weeds in grasslands: the role of allelopathy in Acroptilon repens invasion
TLDR
Allelopathic interactions were an important component of the invasion dynamics of this perennial invasive weed, and further field investigations are warranted. Expand
GLOBAL PATTERNS OF PLANT INVASIONS AND THE CONCEPT OF INVASIBILITY
With a simple model, I show that comparisons of invasibility between regions are impossible to make unless one can control for all of the variables besides invasibility that influence exoticExpand
The Role of Chemical Inhibition (Allelopathy) in Vegetational Composition
TLDR
The deterioration of old Salvia stands, apparently by auto-initoxication, suggests that allelopathy could be a significant factor in plant succession in many kinds of vegetation. Expand
ALLELOPATHY AND ITS INFLUENCE ON THE DISTRIBUTION OF PLANTS IN AN ILLINOIS OLD-FIELD
TLDR
It was concluded that the types of allelopathy which were tested by these bioassay results were not demonstrably effective under field conditions, that perhaps any species can be shown to have allelopathic properties in bioassays, and thatBioassays may, for many communities, have no ecological meaning.

The Ecology of Invasions by Animals and Plants
TLDR
The first book on invasion biology, and still the most cited, Elton's masterpiece provides an accessible, engaging introduction to one of the most important environmental crises of the authors' time. Expand
