TLDR
19 testable hypotheses that explain temporal and spatial variation in impact are identified and reviewed and highlight the importance of the functional ecology of the nonnative species and the structure, diversity, and evolutionary experience of the recipient community as general determinants of impact.Abstract:
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 broad theoretical framework. The context dependency of impact has fueled the perception that meaningful generalizations are nonexistent. Here, we identified and reviewed 19 testable hypotheses that explain temporal and spatial variation in impact. Despite poor validation of most hypotheses to date, evidence suggests that each can explain at least some impacts in some situations. Several hypotheses are broad in scope (applying to plants and animals in virtually all contexts) and some of them, intriguingly, link processes of colonization and impact. Collectively, these hypotheses highlight the importance of the functional ecology of the nonnative species and the structure, diversity, and evolutionary experience of the recipient community as general determinants of impact; thus, they could provide the foundation for a theoretical framework for understanding and predicting impact. Further substantive progress toward this goal requires explicit consideration of within-taxon and across-taxa variation in the per capita effect of invaders, and analyses of complex interactions between invaders and their biotic and abiotic environments.read more

The Ecology of Invasions by Animals and Plants
Arnold B. Erickson,Charles Elton +1 more
TL;DR: Elton's "The Ecology of Invasions by Animals and Plants" as mentioned in this paper is one of the most cited books on invasion biology, and it provides an accessible, engaging introduction to the most important environmental crises of our time.

Global ecological impacts of invasive species in aquatic ecosystems
TL;DR: The synthesis suggests a strong negative influence of invasive species on the abundance of aquatic communities, particularly macrophytes, zooplankton and fish, and proposes a framework of positive and negative links between invasive species at four trophic positions and the five different components of recipient communities.

TL;DR: Improved international cooperation is crucial to reduce the impacts of invasive alien species on biodiversity, ecosystem services, and human livelihoods, as synergies with other global changes are exacerbating current invasions and facilitating new ones, thereby escalating the extent and impacts of invaders.

TL;DR: 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 is presented.
A proposed unified framework for biological invasions.

TL;DR: This article proposed a unified framework for biological invasions that reconciles and integrates the key features of the most commonly used invasion frameworks into a single conceptual model that can be applied to all human-mediated invasions.

Is invasion success explained by the enemy release hypothesis
TL;DR: Given the complexity of processes that underlie biological invasions, it is argued against a simple relationship between enemy ‘release’ and the vigour, abundance or impact of NIS.

Characterizing ecosystem‐level consequences of biological invasions: the role of ecosystem engineers
TL;DR: 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.

Biological invasions and ecosystem processes : towards an integration of population biology and ecosystem studies
TL;DR: Much of the recent progress in ecosystem ecology can be traced to studies which have examined the responses of ecosystems to disturbance, which have documented the reestablishment of biotic regulation of water and nutrient cycling during secondary succession.

TL;DR: For example, this paper found that areas of low plant spe- cies richness may be invaded more easily than areas of high plant species richness, and that this pattern may be more closely related to the degree resources are available in native plant communities, independent of species richness.
