▪ Abstract Edge effects have been studied for decades because they are a key component to
understanding how landscape structure influences habitat quality. However, making sense …

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 …

Nitrogen (N) and phosphorus (P) availability limit plant growth in most terrestrial ecosystems.
This review examines how variation in the relative availability of N and P, as reflected by N …

Invasion ecology, the study of how organisms spread in habitats to which they are not native,
asks both about the invasiveness of species and the invasibility of habitats: Which species …

The invasion paradox describes the co‐occurrence of independent lines of support for both
a negative and a positive relationship between native biodiversity and the invasions of …

A venerable generalization about community resistance to invasions is that more diverse
communities are more resistant to invasion. However, results of experimental and …

Assessments of the 'quality', condition or status of stands of native vegetation or habitat are
now commonplace and are often an essential component of ecological studies and planning …

Experiments assessing the effects of biodiversity on ecosystem functioning initially aimed at
establishing whether such relationships exist (eg Naeem et al. 1995; Tilman et al. 1996; …

The effect of evolutionary history on local‐scale diversity patterns has often been suggested,
but not shown. I explored whether widely described local‐scale relationships between plant …

There is an urgent need to improve the evaluation of conservation interventions. This
requires specifying an objective and a frame of reference from which to measure …
