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

Potential impact of four invasive alien plants on the provision of ecosystem services in Europe under present and future climatic scenarios
TL;DR: In this paper , the potential impacts of four invasive alien plant species (Ailanthus altissima, Baccharis halimifolia, Impatiens glandulifera and Pueraria montana) on the provision of three ecosystem services in Europe were evaluated under current and future climate change scenarios.

To list or not to list: Using time since invasion to refine impact assessment for an exotic plant proposed as noxious
TL;DR: In this article, the authors augmented standard observational methods by using local-scale time-since-invasion information in conjunction with rapidly gathered plant abundance data to evaluate potential impacts of common buckthorn (Ramnus cathartica) in the early stages of invasion in Montana, USA.

Invasive Mite Species in the Americas: Bioecology and Impact
TL;DR: Phytophagous mites are feasible to become invasive species since they are able to provoke severe damage to plants and due to the small size, they can be transported throughout the world and established in new areas where favorable conditions and the absence of efficient natural enemies favor their development.

In Nitrate-Rich Soil, Fallopia x bohemica Modifies Functioning of N Cycle Compared to Native Monocultures
Amélie A. M. Cantarel,Soraya Rouifed,Laurent Simon,Julien Bourg,Jonathan Gervaix,Leslie Blazère,Sophie Poussineau,Charline Creuzé des Châtelliers,Florence Piola +8 more
TL;DR: Investigating the effects of the presence of Fallopia x bohemica on the traits of three native species and interspecific competition on nitrification, denitrification, and related microbial communities found that competition for nitrogen among plants and between plants and microorganisms is highly dependent on species traits and environmental conditions.

Species identity and diversity effects on invasion resistance of tropical freshwater plant communities
Antonella Petruzzella,Tauany A. da S. S. R. Rodrigues,Casper H. A. van Leeuwen,Francisco de Assis Esteves,Marcos Paulo Figueiredo-Barros,Elisabeth S. Bakker +5 more
TL;DR: It is shown that resistance provided by these tropical freshwater submerged plant communities to invasive species contrasts to resistance described for other ecosystems, and emphasizes the need to include understudied systems when predicting patterns of species invasiveness and ecosystem invasibility across biomes.

Mechanisms of Maintenance of Species Diversity
TL;DR: Stabilizing mechanisms are essential for species coexistence and include traditional mechanisms such as resource partitioning and frequency-dependent predation, as well as mechanisms that depend on fluctuations in population densities and environmental factors in space and time.

TL;DR: This framework is used to discuss why the metacommunity concept is useful in modifying existing ecological thinking and illustrate this with a number of both theoretical and empirical examples.

Resource Availability and Plant Antiherbivore Defense
TL;DR: Resource availability in the environment is proposed as the major determinant of both the amount and type of plant defense, and theories on the evolution of plant defenses are compared with other theories.

A General Hypothesis of Species Diversity
TL;DR: A new hypothesis, based on differences in the rates at which populations of competing species approach competitive equilibrium (reduction or exclusion of some species), is proposed to explain patterns of species diversity.
