As nonindigenous species continue to displace native species and disrupt ecosystems, understanding the degree to which native species richness affects the vulner- ability of communities to nonindigenous species invasions has grown in importance. Native and exotic species diversity are often positively correlated in large-scale observational studies, but negatively correlated in small-scale experimental studies. This discrepancy suggests that the scale of invasion studies may be an important… Expand

Species diversity, invasion success, and ecosystem functioning: disentangling the influence of resource competition, facilitation, and extrinsic factors
TLDR
Observational data is applied to a study of the consequences of species loss for invasion to conclude that biotic resistance, as identified in experi- ments, is a consistent effect of diversity that can be explained mechanistically at even a landscape scale, but that it plays a dominant role only when total diversity is constrained by resource limitation. Expand
Native turncoats and indirect facilitation of species invasions
TLDR
The term ‘native turncoats’ is coined to describe native facilitators of non-native species and eight ways they may indirectly facilitate species invasion are identified and found that native turncoat effects increase with the number of resources and native species. Expand
Resolving the invasion paradox: pervasive scale and study dependence in the native-alien species richness relationship.
TLDR
While plot size explained most variation, the N AR was less positive in grassland habitats and in the Australasian region, suggesting the NAR depends strongly on how different authors choose their study system or study design. 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
Productivity alters the scale dependence of the diversity-invasibility relationship.
TLDR
The change in the relationship between native and exotic diversity occurs whenever environmental conditions change to promote species coexistence rather than competitive exclusion, which occurred within a single spatial scale when the environment shifted from being locally unproductive to productive. Expand
From richer to poorer: successful invasion by freshwater fishes depends on species richness of donor and recipient basins.
TLDR
A negative relationship between native and non-native species richness in local assemblages was found at the global scale, while regional patterns revealed the opposite trend, implying that coevolved ecological interactions in species-rich systems inhibit establishment of generalist non- native species from less diverse communities. Expand
Species-Rich Scandinavian Grasslands are Inherently Open to Invasion
TLDR
Results from an additional experiment suggested that these species-rich grasslands are effectively open to invasion and that diversity may be immigration driven, and species richness is no barrier to invasion. Expand
Factors affecting the community invasibility of tropical dry forests and the implications for ecological restoration
The invasion paradox describes the scale dependence of native-exotic richness relationships (NERRs), where NERRs are negative at neighborhood scales and positive at landscape scales. However, a lackExpand
Species invasion in the marine fouling communities of British Columbia : factors that influence invasion dynamics and how they may affect Botrylloides violaceus
TLDR
Salinity had a positive impact on native species richness as well, supporting the environmental favourability hypothesis, and suggests that knowledge of relevant environmental conditions is more important for the management of invasive species than previously thought. Expand
Environmental Productivity and Biodiversity Effects on Invertebrate Community Invasibility
TLDR
The experimental study supports the idea that niche availability and community interactions define community invasibility and does not support the application of a neutral community model for local food web management where predictions of exotic species impacts are needed. Expand

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 byExpand
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
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
Plant diversity increases resistance to invasion in the absence of covarying extrinsic factors
TLDR
A strong inverse association between resident diversity and invader performance is found as predicted by Elton's hypothesis, and covarying extrinsic factors may obscure the negative impact of diversity on invader success. 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

TLDR
A logical framework for an island-biogeographic theory in which species turnover is low even in the face of persistent invasions and for the protection of fragile native species from invading exotics is provided. Expand
Exotic plant species in a C4-dominated grassland: invasibility, disturbance, and community structure
TLDR
Results provide strong evidence for the role of community structure, as affected by disturbance, in determining invasibility of this grassland, and a significant positive relationship between exotic and native species richness was observed within a disturbance regime. Expand
