Elton revisited: a review of evidence linking diversity and invasibility

  title={Elton revisited: a review of evidence linking diversity and invasibility},
  author={Jonathan M. Levine and Carla M. D’Antonio},
It is commonly believed that diverse communities better resist invasion by exotic species than do simple communities. We examined the history of this notion, and evaluated theoretical and empirical work linking diversity and invasions. We found that much of the historical work that has contributed to the perception that diverse communities are less invasible, including Elton's observations and MacArthur's species-packing and diversity-stability models, is based on controversial premises…

It is found that high functional diversity reduced the success of Centaurea by reducing resource availability, and communities with fewer species may be more likely to decline as a consequence of invasion.
Diversity-invasibility across an experimental disturbance gradient in Appalachian Forests.
Results suggest that more nonnative plants may invade species-rich communities compared to species-poor communities following disturbance, and no correlation between native and nonnative species richness before disturbance except at the largest spatial scale, but a positive relationship after disturbance across scales and levels of disturbance.
Biodiversity as a barrier to ecological invasion
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.
Dukes Biodiversity and invasibility in grassland microcosms
In the years since Charles Elton proposed that more diverse communities should be less susceptible to invasion by exotic species, empirical studies have both supported and refuted Elton's hypothesis.
Mechanisms of invasions: can the recipient community influence invasion rates?
The ability of a community to resist the establishment of new populations comes not from species richness, diversity or the average connectivity of the system per se, but from the ability of established species to utilise the maximum amount of resources in the long term and realise the smallest amount of variability in resource availability.
Species Invasions and the Relationships between Species Diversity , Community Saturation , and Ecosystem Functioning 2
this chapter, we examine how the ecology of invasions helps clarify the relationships among community saturation, diversity, and ecosystem functioning. We begin with a theoretical approach that
Plant diversity increases resistance to invasion in the absence of covarying extrinsic factors
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.
A strong negative correlation between native-species richness and the number and frequency of nonnative invaders at the scale of both a single quadrat and an entire site is found, which suggests that the means by which diversity affects invasion resistance in experiments is important in determining the distribution of invasive species in the field.
Maintenance of diversity altered by a shift in dominant species: implications for species coexistence.
Diversity patterns between 2 panel studies (1979 to 1982; 2003 to 2006), one conducted before the establishment of invasive colonial ascidians, revealed an increase in species diversity and short-term recruitment studies designed to elucidate mechanisms behind the patterns observed in long-term studies suggest contrasting methods of maintaining diversity.
Species diversity, invasion success, and ecosystem functioning: disentangling the influence of resource competition, facilitation, and extrinsic factors
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.


Invasion resistance, species build‐up and community collapse in metapopulation models with interspecies competition
A logical framework for an island-biogeographic theory based on species interactions and invasions and for the protection of fragile native species from invading exotics is provided.
Competition and Biodiversity in Spatially Structured Habitats
The spatial competition hypothesis seems to explain the coexistence of the numerous plant species that compete for a single limiting resource in the grasslands of Cedar Creek Natural History Area and provides a testable, alternative explanation for other high diversity communities, such as tropical forests.

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.
Biological Invasions as Agents of Change on Islands Versus Mainlands
Over the past decade, the Scientific Committee on Problems of the Environment (SCOPE) has devoted considerable attention to the ecology of invasive organisms (e.g., Brockie et al. 1988; Loope et al.

Species Richness and Resistance to Invasions
Traditionally, tropical forests, and especially tropical rain forests, have been contrasted with extratropical communities in terms of their species diversity and stability (Elton 1958).

It is suggested that abiotic suitability is of paramount importance in determining rate of invasion for the Argentine ant, a widespread invasive species of northern California.

Biological invasions and ecosystem processes : towards an integration of population biology and ecosystem studies
Much of the recent progress in ecosystem ecology can be traced to studies which have examined the responses of ecosystems to disturbance, which have documented the reestablishment of biotic regulation of water and nutrient cycling during secondary succession.
