Non-native species can cause the loss of biological diversity (i.e., genetic, species, and ecosystem diversity) and threaten the well-being of humans when they become invasive. In some cases, however, they can also provide conservation benefits. We examined the ways in which non-native species currently contribute to conservation objectives. These include, for example, providing habitat or food resources to rare species, serving as functional substitutes for extinct taxa, and providing… Expand

The biodiversity impacts of non-native species should not be extrapolated from biased single-species studies
TLDR
It is argued that meta-analyses of the impacts of individual non-native species on natives, no matter how meticulous or objective, should not be generalized beyond the set of ‘training’ species, and two meta-Analyses that make general conclusions from impact studies skewed towards ‘transformers’, the most extreme invaders are discussed. Expand
Rare species and aliens: reconsidering non‐native plants in the management of natural areas
TLDR
It is suggested greater emphasis be placed on the role species play in ecological settings regardless of their origin, recognizing that only some non-native plants are invasive, that the risk of causing ecological harm varies considerably, and that distributions will change as species migrate in response to climate change. Expand
Non-Native Invasive Species as Ecosystem Service Providers
Non-native or alien species present a range of threats to native ecosystems and human well-being. Many such species have selective advantages over native species, such as faster growth andExpand
Do non-native species contribute to biodiversity?
TLDR
It is argued that biodiversity and sustainability indices should include all species, not only consistent with definitions of biodiversity but also will promote the idea that long-term, sustainable, human well-being is intricately tied to benefits derived from nature. Expand
Defining the Impact of Non-Native Species
TLDR
It is argued that explicitly defining the impact of non-native species will promote progress toward a better understanding of the implications of changes to biodiversity and ecosystems caused by non- native species; help disentangle which aspects of scientific debates about non-Native species are due to disparate definitions and which represent true scientific discord; improve communication between scientists from different research disciplines and between scientists, managers, and policy makers. Expand
Contrasting ecological roles of non-native ungulates in a novel ecosystem
TLDR
This study examined the effects of two long-established non-native species—Philippine deer and feral pigs in Guam, Micronesia, where native vertebrate frugivores are functionally absent leaving forests devoid of seed dispersers, suggesting that ecological function may be more important to consider in managing novel systems. Expand
Native faunal communities depend on habitat from non-native plants in novel but not in natural ecosystems
TLDR
The results indicate the ecological functions of non-native plant species vary depending on habitat and need to be considered for management and apply a standardized approach across a broad range of conditions at the landscape and habitat scale. Expand
The establishment of non-native plant species in relation to climate and land use in Britain
Human transport of species around Earth has led to the intentional and accidental introduction of many species into new regions. Introduced species can have significant impacts outside their nativeExpand
Invasive plant species in the Swedish flora: developing criteria and definitions, and assessing the invasiveness of individual taxa
TLDR
In this study, all 721 presently established vascular plant and bryophyte taxa known to have been introduced to, or to have immigrated to, Sweden since the year 1700 are assessed for their invasive potential. Expand
Are non-native species more likely to become pests? Influence of biogeographic origin on the impacts of freshwater organisms3
TLDR
Non-native species comprised the majority (60%) of aquatic pests in North America and Europe and were six times as likely to be pests as compared with native species, and the incidence of pest species was greatest among foreign invaders. Expand

Do Non-Native Species Threaten The Natural Environment?
TLDR
To assert that non- native species threaten biodiversity or undermine ecosystem health, however, may be to draw conceptual entailments or consequences from definitions of “biodiversity” and “integrity” that arbitrarily exclude non-native species or make the presence of exotic species a per se indicator of decline. Expand
Can Invasive Species Facilitate Native Species? Evidence of How, When, and Why These Impacts Occur
TLDR
Evidence is presented for several mechanisms that exemplify how exotic species can facilitate native species and predict that facilitative impacts on native species will be most likely when invasive species provide a limiting resource, increase habitat complexity, functionally replace a native species, or ameliorate predation or competition.

Invasive non-native species' provision of refugia for endangered native species.

TLDR
The thick and dense litter of Casuarina appears to provide refugia for native land snails by protecting them from predation by rats; thus, eradication of rats should precede eradications of CasUarina. Expand
Species invasions and extinction: The future of native biodiversity on islands
  • D. Sax, S. Gaines
  • Biology, Medicine
  • Proceedings of the National Academy of Sciences
  • 2008
TLDR
It is shown that the number of naturalized plant species has increased linearly over time on many individual islands, and the mean ratio of naturalization to native plant species across islands has changed steadily for nearly two centuries, suggesting that many more species will become naturalized on islands in the future. Expand
Evolutionary biology and practical conservation: bridging a widening gap
TLDR
Improved methods for integrating the work of scientists and policymakers is recommended, from the beginning to end of the planning process, to help maintain evolutionary processes in natural populations. Expand
Mammal invaders on islands: impact, control and control impact
TLDR
It is difficult to predict the outcome of the removal of key species, such as a top predator, given the numerous and complex population interactions among island species, and justifies careful pre‐control study and preparation prior to initiating the eradication of an alien species, in order to avoid an ecological catastrophe.

Park Management of Exotic Plant Species: Problems and Issues
: Vegetation management policies in public parks in the United States call for the removal of exotic species to the extent feasible. The underlying goal is to preserve samples of wilderness byExpand
Scale, connectivity, and incentives in the introduction and management of non‐native species: the case of exotic salmonids in Patagonia
TLDR
It is proposed that three interrelated properties of these case studies (scale, connectivity, and incentives for conservation) determine the ability to identify and promote situations that balance production and the integrity of nature. Expand
Characterizing ecosystem‐level consequences of biological invasions: the role of ecosystem engineers
TLDR
Recognition of engineering as a major means by which invasive species affect ecosystems provides a unifying theme for invasion biology and offers a chance to consider more fully the general role of species in ecosystems. Expand
The paradox of the long-term positive effects of a North American crayfish on a European community of predators.
TLDR
This work investigates the potential facilitative effects of the North American red swamp crayfish (Procambarus clarkii) on the community of predators in southwestern Spain and reports the first case in which one non-native species is both beneficial and detrimental because it can drive species at lower trophic levels to extinction.
