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.

Prolonged lag in population outbreak of an invasive mussel : a shifting-habitat model
TL;DR: It is suggested that the delayed formation of B. pharaonis beds along the Israeli coast is a consequence of a recent shift in habitat conditions on some platforms, and receding of the biogenic rim at the edge of these platforms allowed more effective washing, reduced sediment accumulation, and reduced perennial algae cover making platforms more suitable for the mussels.

Biomass allocation, growth, and photosynthesis of genotypes from native and introduced ranges of the tropical shrub Clidemia hirta
TL;DR: It is concluded that genetic shifts in resource use, resource allocation, or plasticity do not contribute to differences in habitat distribution and abundance between the native and introduced ranges of C. hirta.

Predicting the number of ecologically harmful exotic species in an aquatic system
Anthony Ricciardi,Rebekah Kipp +1 more
TL;DR: Findings link vector activity and the negative impacts of introduced species on biodiversity, and thus justify management efforts to reduce invasion rates even where numerous invasions have already occurred.

More harm than good: when invader vulnerability to predators enhances impact on native species
Erik G. Noonburg,James E. Byers +1 more
TL;DR: General community ecology theory is applied to determine the conditions under which the net effect of predation on the exotic species is to extirpate the native competitor, providing a simple metric to estimate the threat of native species extinction due to apparent competition posed by an invader.

Establishment and ecosystem effects of the alien invasive red king crab (Paralithodes camtschaticus) in the Barents Sea–a review
TL;DR: Characteristics of the Barents Sea and the crab itself that may explain its success include suitable habitat for settlement and growth of the larvae; the wide range of habitats occupied throughout its life history, high mobility, generalist prey choice, low fishing pressure during establishment, and the lack of parasites.
