A predictive understanding of the ecological impacts of nonnative species has been slow to
develop, owing largely to an apparent dearth of clearly defined hypotheses and the lack of a …

The argument that the threat posed by introduced species is overblown is often buttressed
by the observation that native species sometimes also become invasive. An examination of …

An increasing number of studies in a wide range of natural systems have investigated how
pulses of resource availability influence ecological processes at individual, population, and …

The roles of species richness, resource use, and resource availability are central to many
hypotheses explaining the diversity–invasion phenomenon but are generally not …

Human modification of the environment is causing both loss of species and changes in
resource availability. While studies have examined how species loss at the local level can …

Grassland diversity can support sustainable intensification of grassland production through
increased yields, reduced inputs and limited weed invasion. We report the effects of diversity …

The grazing exclusion in degraded grassland has been extensively used to prevent the loss
of grassland resources and to improve grassland services. The effects of grazing exclusion …

This study presents an updated analysis of the relative generality of invasion mechanisms in
invasive plants. We categorised eight invasion mechanisms into three classes, according to …

In many systems, native communities are being replaced by novel exotic‐dominated ones.
We experimentally compared species diversity decline between nine‐species grassland …

Although global change is known to influence plant invasion, little is known about
interactions between altered precipitation and invasion. In the North American mixedgrass …
