Ecological impacts of invasive alien plants: a meta-analysis of their effects on species, communities and ecosystems.
TLDR
Overall, alien species impacts are heterogeneous and not unidirectional even within particular impact types, and by the time changes in nutrient cycling are detected, major impacts on plant species and communities are likely to have already occurred. Expand
Trade, transport and trouble: managing invasive species pathways in an era of globalization

  • 1 February 2009
TLDR
The links between the main drivers of globalization and biological invasions are reviewed and state-of-the-art approaches to pathway risk assessment are examined to illustrate new opportunities for managing invasive species. Expand
Are treelines advancing? A global meta-analysis of treeline response to climate warming.
TLDR
Diffuse treelines may be more responsive to warming because they are more strongly growth limited, whereas other treeline forms may be subject to additional constraints. Expand
Grasping at the routes of biological invasions: a framework for integrating pathways into policy
TLDR
A framework is proposed to facilitate the comparative analysis of invasion pathways by a wide range of taxa in both terrestrial and aquatic ecosystems and helps identify existing gaps in current knowledge of pathways and highlight the limitations of existing legislation to manage introductions of alien species. Expand
A global assessment of invasive plant impacts on resident species, communities and ecosystems: the interaction of impact measures, invading species' traits and environment
TLDR
It is shown that there is no universal measure of impact and the pattern observed depends on the ecological measure examined, and some species traits, especially life form, stature and pollination syndrome, may provide a means to predict impact, regardless of the particular habitat and geographical region invaded. Expand
Beyond control : wider implications for the management of biological invasions
TLDR
Prevention is widely promoted as being a more environmentally desirable strategy than actions undertaken after IAS establishment, yet is hindered by the difficulty in separating invasive from non-invasive alien species. Expand
Alien species in a warmer world: risks and opportunities.
TLDR
It is emphasised that global warming has enabled alien species to expand into regions in which they previously could not survive and reproduce and management practices regarding the occurrence of 'new' species could range from complete eradication to tolerance. Expand
Bias and error in understanding plant invasion impacts.
TLDR
The first detailed critique of quantitative field studies of alien plant impacts is presented and biases in the biogeography and life form of the target species, the responses assessed, and the extent to which spatial variability is addressed are highlighted. Expand
A Unified Classification of Alien Species Based on the Magnitude of their Environmental Impacts
We present a method for categorising and comparing alien or invasive species in terms of how damaging they are to the environment, that can be applied across all taxa, scales, and impact metrics.
Herbivores inhibit climate‐driven shrub expansion on the tundra
Recent Pan-Arctic shrub expansion has been interpreted as a response to a warmer climate. However, herbivores can also influence the abundance of shrubs in arctic ecosystems. We addressed these altExpand
