TLDR
The costs and benefits of IAS for provisioning, regulating and cultural services are assessed, and the synergies and tradeoffs associated with these impacts are illustrated using case studies that include South Africa, the Great Lakes and Hawaii.Abstract:
Although the effects of invasive alien species (IAS) on native species are well documented, the many ways in which such species impact ecosystem services are still emerging. Here we assess the costs and benefits of IAS for provisioning, regulating and cultural services, and illustrate the synergies and tradeoffs associated with these impacts using case studies that include South Africa, the Great Lakes and Hawaii. We identify services and interactions that are the least understood and propose a research and policy framework for filling the remaining knowledge gaps. Drawing on ecology and economics to incorporate the impacts of IAS on ecosystem services into decision making is key to restoring and sustaining those life-support services that nature provides and all organisms depend upon.read more

A global assessment of invasive plant impacts on resident species, communities and ecosystems: the interaction of impact measures, invading species' traits and environment

TL;DR: 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.

Invasive Species, Environmental Change and Management, and Health
Petr Pyšek,David M. Richardson +1 more
TL;DR: Invasive species are a major element of global change and are contributing to biodiversity loss, ecosystem degradation, and impairment of ecosystem services worldwide as discussed by the authors, and new approaches are emerging for describing and evaluating impacts of invasive species, and for translating these impacts into monetary terms.

Ecosystem Consequences of Biological Invasions
TL;DR: In this article, a variety of interacting, mutually reinforcing mechanistic pathways, including species' resource acquisition traits; population densities; ability to engineer changes to physical environmental conditions; effects on disturbance, especially fire; regimes; the ability to structure habitat for other species; and their impact on food webs, are discussed.

State of the world's freshwater ecosystems: physical, chemical, and biological changes.
TL;DR: In this article, a natural capital framework is used to assess freshwater ecosystem health and to understand the causes and consequences of change as well as the correctives for adverse change in any given watershed.

Update on the environmental and economic costs associated with alien-invasive species in the United States
TL;DR: About 42% of the species on the Threatened or Endangered species lists are at risk primarily because of alien-invasive species.

Biological invasions by exotic grasses, the grass/fire cycle, and global change
TL;DR: Biological invasions into wholly new regions are a consequence of a far reaching but underappreciated component of global environmental change, the human-caused breakdown of biogeographic barriers to species dispersal.

Quantifying threats to imperiled species in the united states
TL;DR: Surprisingly, there have been surprisingly few analyses of the extent to which each of these factors-much less the more specific deeds encomDavid S. Wilcove is a senior ecologist at the Environmental Defense Fund and David Rothstein re ceived his J.D. in 1997 from Northeastern

Introduced species: a significant component of human-caused global change
TL;DR: It is suggested that biological invasions by notorious species like the zebra mussel, and its many less-famous counterparts, have become so widespread as to represent a significant component of global environmental change.

Impact: Toward a Framework for Understanding the Ecological Effects of Invaders

TL;DR: This paper argues that the total impact of an invader includes three fundamental dimensions: range, abundance, and the per-capita or per-biomass effect of the invader, and recommends previous approaches to measuring impact at different organizational levels, and suggests some new approaches.
