In a California riparian system, the most diverse natural assemblages are the most invaded by exotic plants. A direct in situ manipulation of local diversity and a seed addition experiment showed that these patterns emerge despite the intrinsic negative effects of diversity on invasions. The results suggest that species loss at small scales may reduce invasion resistance. At community-wide scales, the overwhelming effects of ecological factors spatially covarying with diversity, such as… Expand

Invasion impacts local species turnover in a successional system
TLDR
Declines in species richness associated with L. japonica invasion resulted from effects on local colonization rates only and not through the competitive displacement of established species, suggesting that some species are more susceptible to invasion than others. Expand
Dominance of non-native species increases over time in a historically invaded strandline community.
TLDR
Whether native and exotic dominance had changed, whether nativerich sites were less likely to be impacted by exotics over time, whether changes in dominance were driven by large changes in a small number of outlier species or by small, incremental changes among many species and whether disturbance mediated any of these relationships.

DIVERSITY AND INVASIBILITY OF SOUTHERN APPALACHIAN PLANT COMMUNITIES
We propose that the relationship between diversity and community invasibility depends on the degree to which community composition is driven by immigration processes. When immigration is enhanced by… Expand
Rare Species Loss Alters Ecosystem Function – Invasion Resistance
TLDR
It is found that exotic species establishment was higher in plots in which diversity was successfully reduced by removal treatments and was inversely related to imposed species richness. Expand
Environmental filtering and competitive exclusion drive biodiversity‐invasibility relationships in shallow lake plant communities
1. Understanding the processes that influence the diversity of ecological communities and their susceptibility to invasion by exotic species remains a challenge in ecology. In many systems, a… Expand
The relationship between community diversity and exotic plants: cause or consequence of invasion?
TLDR
The conceptual framework provides a structure to synthesize the current body of research, suggests research needed to fill the gaps in understanding and to organize results from future research, and is a powerful tool to guide ecological understanding of the relationship between invasion and diversity across systems, species, and scales. Expand
Biodiversity as a barrier to ecological invasion
TLDR
It is shown that species diversity in small experimental grassland plots enhances invasion resistance by increasing crowding and species richness in localized plant neighbourhoods, and suggests that local biodiversity represents an important line of defence against the spread of invaders. Expand
ECOLOGICAL RESISTANCE TO BIOLOGICAL INVASION OVERWHELMED BY PROPAGULE PRESSURE
TLDR
This is the first experimental study to demonstrate the primacy of propagule pressure as a determinant of habitat invasibility in comparison with other candidate controlling factors. Expand
WEAK VS. STRONG INVADERS OF NATURAL PLANT COMMUNITIES: ASSESSING INVASIBILITY AND IMPACT
TLDR
Examination of local-scale relationships between native and exotic plant taxa in bunchgrass communities of western Montana, USA found that measures of biotic resistance, or the ability of communities to resist invasions, are weak. Expand
Beyond biodiversity: individualistic controls of invasion in a self‐assembled community
TLDR
Control of species invasion in this system is individualistic, caused by a variety of community-level mechanisms rather than a single prevailing richness effect, which appears to be a mixture of compositional influences and a richness effect. Expand

Species Diversity and Invasion Resistance in a Marine Ecosystem.
TLDR
In experimental communities of sessile marine invertebrates, increased species richness significantly decreased invasion success, apparently because species-rich communities more completely and efficiently used available space, the limiting resource in this system. Expand
Effects of plant species richness on invasion dynamics, disease outbreaks, insect abundances and diversity.
TLDR
Experimental reductions in grassland plant richness increase ecosystem vulnerability to invasions by plant species, enhance the spread of plant fungal diseases, and alter the richness and structure of insect communities, suggesting that the loss of basal species may have profound effects on the integrity and functioning of ecosystems.

A test of the effects of functional group richness and composition on grassland invasibility.
TLDR
Overall invasion success was negatively related to resident functional group richness, but there was only weak evidence that resident species repelled functionally similar invaders and other factors seem to have been more important to community in- vasibility. Expand
Invasibility of experimental habitat Islands in a California winter annual grassland
TLDR
In an experimental test of plant community invasibility, seeds of a native ruderal, California poppy, are introduced at fixed density into experimental plots in a California winter annual grassland and species-rich plots were more invasible. Expand

TLDR
It is suggested that the high mortality and low diversity in the nitrogen addition plots, but not in the more productive watered plots, was due to limitation by nitrogen earlier than limitation by water during the growing season. Expand

COMMUNITY STRUCTURE AND FOREST INVASION BY AN EXOTIC HERB OVER 23 YEARS
TLDR
The invasion of a New Zealand mountain beech forest by the exotic perennial herb, Hieracium lepidulum, was studied to show that community structure was also significant at a microsite scale and to predict which plots were invaded. Expand
