Exotic species affect the biogeochemical pools and fluxes of materials and energy, thereby altering the fundamental structure and function of their ecosystems. Rapidly accumulating evidence from many species of both animal and plant invaders suggests that invasive species often increase pool sizes, particularly of biomass, and promote accelerated flux rates, but many exceptions can be found. Ecosystem dynamics are altered through a variety of interacting, mutually reinforcing mechanistic… 
Biotic interactions drive ecosystem responses to exotic plant invaders
TLDR
Novel biological interactions with exotic species are a more important driver of ecosystem transformation than was previously recognized and underpin ecosystem transformations in carbon cycling rates.
Ecological impacts of invasive alien plants: a meta-analysis of their effects on species, communities and ecosystems.
TLDR
Overall, alien species impacts are heterogeneous and not unidirectional even within particular impact types, and by the time changes in nutrient cycling are detected, major impacts on plant species and communities are likely to have already occurred.
Mechanisms of Plant Invasions of North American and European Grasslands
North American and European grasslands consist of relatively young communities that have evolved under human influences. These communities are uniformly sensitive to top-down controls and exhibit
Diverse effects of invasive ecosystem engineers on marine biodiversity and ecosystem functions: A global review and meta‐analysis
TLDR
It is found that IEE had a significant effect in most studies testing impacts on individual species, but the overall effect size was small and negative, and understanding how IEE may alter biodiversity-ecosystem function relationships should be a primary focus of future studies of invasion biology.
Mutualistic Interactions and Biological Invasions
TLDR
This work identifies traits that influence invasiveness or invasibility through mutualistic interactions and examines the key mechanisms whereby such positive interactions mediate invasions and are in turn influenced by invasions.
Impacts of invasive plants on resident animals across ecosystems, taxa, and feeding types: a global assessment.
TLDR
A comprehensive meta-analysis covering 198 field and laboratory studies reporting a total of 3624 observations of invasive plant effects on animals found that invasive plants reduced overall animal abundance, diversity and fitness.
Changes in Primary Production and Carbon Sequestration after Plant Invasions
The potential differences in ecophysiological traits between native and invasive plants can change ecosystem functioning. In this chapter, we discuss the effects of plant invasions on ecosystem

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.
Effects of Exotic Plant Invasions on Soil Nutrient Cycling Processes
TLDR
This work has reviewed studies that compare pool sizes and flux rates of the major nutrient cycles in invaded and noninvaded systems for invasions of 56 species and suggests that invasive plant species frequently increase biomass and net primary production, increase N availability, alter N fixation rates, and produce litter with higher decomposition rates than co-occurring natives.
EFFECTS OF BIODIVERSITY ON ECOSYSTEM FUNCTIONING: A CONSENSUS OF CURRENT KNOWLEDGE
TLDR
Understanding this complexity, while taking strong steps to minimize current losses of species, is necessary for responsible management of Earth's ecosystems and the diverse biota they contain.
Mechanisms underlying the impacts of exotic plant invasions
TLDR
It is found that, while numerous studies have examined the impacts of invasions on plant diversity and composition, less than 5% test whether these effects arise through competition, allelopathy, alteration of ecosystem variables or other processes.
Impacts of Invasive Species on Ecosystem Services
The impacts of invasive species on ecosystem services have attracted worldwide attention. Despite the overwhelming evidence of these impacts and a growing appreciation for ecosystem services,
Riparian plant invasions: hydrogeomorphological control and ecological impacts
Biological invasions are a threat to ecosystems across all biogeographical realms. Riparian habitats are considered to be particularly prone to invasion by alien plant species and, because riparian
NEIGHBORHOOD MODELS OF THE EFFECTS OF INVASIVE TREE SPECIES ON ECOSYSTEM PROCESSES
TLDR
The invasion of northeastern forests by Norway maple and tree of heaven is characterized by predictable, neighborhood-specific acceleration of nutrient cycling rates and localized increases in nutrient pools, which have enormous potential for the modification of competitive hierarchies in forest communities.
Ecosystem engineering by invasive exotic beavers reduces in-stream diversity and enhances ecosystem function in Cape Horn, Chile
TLDR
This work quantifies the impacts of habitat and resource modifications caused by North American beavers on aquatic macroinvertebrate community structure and stream ecosystem function in the Cape Horn Biosphere Reserve, Chile and shows how diversity and ecosystem function can be decoupled by responding to alterative mechanisms.
Impact of invasive alien plant species on soil processes: a review.
TLDR
Soil processes which change in response to plant invasion and, in turn, affect the recruitment and growth of both native as well as invasive species are often ignored and appropriate management strategy could be developed to combat the onslaught of biological invasion.
