Theory predicts that systems that are more diverse should be more resistant to exotic species, but experimental tests are needed to verify this. 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. Declining biodiversity thus facilitates invasion in this system, potentially… 

Species diversity and biological invasions: relating local process to community pattern.

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

Rare Species Loss Alters Ecosystem Function – Invasion Resistance

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.


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.

Biodiversity and invasibility in grassland microcosms

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.

Species richness and interacting factors control invasibility of a marine community

It is suggested that patches of low diversity and abundance may facilitate invasions, and that such patches, once colonized by non-indigenous species, can resist both native and non-Indigenous species recruitment.

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.

From invasive species to novel ecosystems

This session provides a platform for young marine researchers to present their research on species invasions from the whole spectrum of spatio-temporal scales and methods.

Biodiversity influences invasion success of a facultative epiphytic seaweed in a marine forest

Observational and experimental data show that, at early stages of invasion, species-rich seaweed forests are not more resistant to invasion than species-poor communities, suggesting negative impacts of invasive species on native biodiversity.

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

Community diversity and invasion resistance: An experimental test in a grassland ecosystem and a review of comparable studies

In biodiversity manipulation experiments more diverse communities are generally more resistant to invasion, and positive effects of species diversity on invasion resistance were found in experimental manipulations of plant diversity conducted in the field and in the glasshouse.

Accelerating invasion rate in a highly invaded estuary

Analysis of the San Francisco Bay and Delta ecosystem revealed a large number of exotic species that dominate many habitats in terms of number of species, number of individuals and biomass, and a high and accelerating rate of invasion.

Biodiversity and stability in grasslands

ONE of the ecological tenets justifying conservation of biodiversity is that diversity begets stability. Impacts of biodiversity on population dynamics and ecosystem functioning have long been


Local biotic interactions and recruitment dynamics jointly determined diversity, species composition, and species abundances in these native grassland communities, suggesting that recruitment limitation may be more important, even on a local scale, than often recognized.

The Influence of Functional Diversity and Composition on Ecosystem Processes

Functional composition and functional diversity were the principal factors explaining plant productivity, plant percent nitrogen, plant total nitrogen, and light penetration in grassland plots.

Biodiversity enhances ecosystem reliability

It is found that as the number of species per functional group increased, replicate communities were more consistent in biomass and density measures, suggesting that redundancy (in the sense of having multiple species perfunctional group) is a valuable commodity, and that the provision of adequate redundancy may be one reason for preserving biodiversity.

Biodiversity regulates ecosystem predictability

By manipulating biodiversity in aquatic microbial communities, it is shown that one process, ecosystem respiration, becomes more predictable as biodiversity increases, and analysis of similar patterns extracted from other studies indicates that biodiversity also enhances predictability in terrestrial ecosystems.

Invasibility of experimental habitat Islands in a California winter annual grassland

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.

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.
