Biotic invaders are species that establish a new range in which they proliferate, spread, and persist to the detriment of the environment. They are the most important ecological outcomes from the unprecedented alterations in the distribution of the earth's biota brought about largely through human transport and commerce. In a world without borders, few if any areas remain sheltered from these im- migrations. The fate of immigrants is decidedly mixed. Few survive the hazards of chronic and…

Unraveling the Life History of Successful Invaders
Combining a global comparative analysis of avian introductions with demographic models and phylogenetic comparative methods, it is shown that although rapid population growth may be advantageous during invasions under certain circumstances, more generally successful invaders are characterized by life-history strategies in which they give priority to future rather than current reproduction.

Hard evidence is needed that rates of population growth change over time, along with experiments to reveal the mechanism behind that change, in this issue of PNAS.
Conciliation biology: the eco-evolutionary management of permanently invaded biotic systems
A conciliatory approach to managing systems where novel organisms cannot or should not be eradicated, which utilizes the predictive power of evolutionary theory to offer diverse and flexible pathways to more sustainable outcomes.
The role of evolution in the invasion process
  • S. Novak

    Proceedings of the National Academy of Sciences
  • 2007
The research of Lavergne and Molofsky reported in this issue of PNAS examines the factors that contribute to range expansion and the invasiveness of Phalaris arundinacea L. (reed canarygrass) in North America and provides powerful insights into the role of evolution in the invasion process.
Relative roles of climatic suitability and anthropogenic influence in determining the pattern of spread in a global invader
These analyses on the global-scale distribution of this invasive species provide strong evidence for the interplay of biotic and abiotic determinants of spread and also highlight the challenges of limiting the spread and subsequent impact of highly invasive species.
Human Agency in Biological Invasions: Secondary Releases Foster Naturalisation and Population Expansion of Alien Plant Species

    Biological Invasions
  • 2004
It is shown that introductions on varying spatial scales may strongly foster invasions throughout the whole invasion process, and the term `invasive' should preferably be used in a broader sense to describe the entire invasion process.
Mammal invaders on islands: impact, control and control impact
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.
Impact of Plants Introduced by People During a Time of Rapid Environmental Change
This article argues for long-term, integrated programmes of observation and experimentation in the field and laboratory into the risks that introduced plants pose for native species and ecosystems.
Biological invaders are threats to human health: an overview
It is imperative to improve the understanding of the pathways of arrival of invasive species affecting human health, their biological patterns and the mechanisms of impact, because all this information is essential to develop more effective and stringent policies for preventing and mitigating the negative effects that these species cause.
Plant invasions: their threats in an Irish context.
The impacts of invasive alien plants on native biodiversity and ecosystems are difficult to assess, and are often speciesand context specific, making it almost impossible to make general statements.


Lag times in population explosions of invasive species: causes and implications
Policy makers should understand that good surveillance and monitoring are essential, and that extirpation should be early and vigorous, for the sake of biodiversity losses caused by invasive species.
Biological invasions by exotic grasses, the grass/fire cycle, and global change
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
How Risky is Biological Control
This work addressed the potential harmful effects of non—indigenous species introduced for biological control by undertaking a literature review, and concluded that current regulation of introduced biological—control agents, particularly of entomophages, is insufficient.
Why Do Introduced Species Appear to Devastate Islands More Than Mainland Areas
It is unlikely that, by virtue of their reduced species richness alone, island communities pose less "biotic resistance" to invaders than mainland communities do, but certain entire groups of species, like terrestrial mammals, are often missing from islands, and these absences can predispose certain invaders to be especially likely to survive and to produce particular invaders.
Reducing the risks of nonindigenous species introductions.
A though plants and animals have always spread across the globe, expanding their ranges and invading new territories, human civilization has accelerated these biological invasions to an extraordinary
Comparative ecology of the native and alien floras of the British Isles
This work attempts to identify life history components that allow successful invasion by analysing the life history variables and ecological requirements of plant species that have successfully invaded the U.K. in recent years.
In search of the characteristics of plant invaders
  • J. Roy
  • Environmental Science
  • 1990
This chapter reviews the physiological, demographic and genetic attributes of invaders sensu stricto (excluding native weeds or colonists), and the need for an approach combining ecolological and evolutionary features of habitats and introduced species is emphasized.
Free Trade and Exotic Species Introductions
Several researchers and commentators have addressed the effects of introductions of harmful exotic species (Mooney & Drake 1989; Soule 1990; Temple 1990; U.S. Congress, Office of Technology
Plant invasions: Early and continuing expressions of global change
Through prolific, current use and tacit agreement ‘global change’ refers to permanent alteration of the Biosphere as caused by humans. In practice, most emphasis in predicting global change stems

As supported by empirical precedents, consistent implementation of the general strategy suggested by the model should improve the control of alien plants.
