Changes in environmental conditions often reverse outcomes of competitive interactions among species. Such context dependency implies that the speed, persistence, and ubiquity of anthropogenic habitat alterations may suddenly put even previously well-adapted native species at a competitive disadvantage with non-native species. That is, anthropogenic disturbance may so drastically alter environments that a native species finds itself in an environment that in key ways is just as novel as it is… Expand

Figures from this paper

Spatial pattern of invasion and the evolutionary responses of native plant species
TLDR
This work proposes that the spatial structure of invasion, in particular the size and isolation of invaded patches, is one factor which can influence the evolutionary responses of native species through modifying gene flow and the strength of selection, and presents a conceptual model in which large, dense, and well‐connected patches result in a greater likelihood ofnative species adaptation. Expand
Ecological effects of non-native species in marine ecosystems relate to co-occurring anthropogenic pressures.
TLDR
This global assessment suggests co-existing anthropogenic impacts can intensify the ecological effects of non-native species, including areas in the Mediterranean Sea and along the northwest coast of the USA. Expand
Differential population responses of native and alien rodents to an invasive predator, habitat alteration and plant masting
TLDR
It is proposed that spatio-temporal monitoring data from eradication programmes will clarify the underlying ecological impacts of land-use change and invasive species, and will be useful for future habitat management. Expand
7.03 – Functional Consequences of Invasive Species in Coastal and Estuarine Systems
TLDR
Major functional impacts are assessed by considering invasive species as nutrient and biogeochemical modifiers, trophic transformers, and structural engineers, to synthesize the nature and magnitude of invasion effects on ecosystem function. Expand
Introduced species dominate different responses of grassland communities to climate change on serpentine and nonserpentine soils
TLDR
Analysis of a longterm dataset of species abundance in California grasslands collected during a period of severe drought indicates relatively stable native community composition and strong directional change in introduced species composition, contradicting predictions for how native and introduced species will respond to environmental shifts, but supporting the hypothesis that native and invading species groups have important functional differences that shape their relationships to the environment. Expand
Historical ecology of a biological invasion: the interplay of eutrophication and pollution determines time lags in establishment and detection
TLDR
Recon reconstructing the effect of disturbance on the invasion of the bivalve Anadara transversa from sediment cores in the Adriatic Sea shows that while disturbance does promote invasions, a synergism of multiple disturbances can shift selection regimes beyond tolerance limits and induce significant time lags in establishment. Expand
Nutrients influence the multi-trophic impacts of an invasive species unaffected by native competitors or predators.
TLDR
Results indicate that neither competitors nor predators have likely suppressed the invasion of the banded mystery snail, and highlight that the post-establishment impacts of invasive species are altered by the trophic state of freshwater ecosystems. Expand
Land use intensification differentially benefits alien over native predators in agricultural landscape mosaics.
TLDR
The results suggest that successfully established alien coccinellid species may be ‘disturbance specialists’ that thrive within human-modified habitats, and less-disturbed agroecosystems are desirable to promote the regional conservation of native species within increasingly human-dominated landscapes. Expand
Spatial and environmental factors predict the composition of non-native fish assemblages in Neotropical reservoirs
TLDR
The work tested the hypothesis that the spatial structure, reservoir productivity and morphology, and chronological characteristics are factors related to the composition and abundance of non-native fish species in reservoir, and showed that larger and older reservoirs have a greater abundance of non- native fish species. Expand
Do a threatened native amphibian and its invasive congener differ in response to human alteration of the landscape?
TLDR
This work examined the habitat correlates of distribution, persistence and reproduction of a global invader, the American bullfrog, and compared these correlates with those of a threatened, native congener, the California red-legged frog (Rana draytonii). Expand

Effects of invasive, non-indigenous plant species on ecosystem processes: lessons from Florida.
TLDR
It is suggested that ecosystem alteration may be relatively common among invasive non-indigenous species and where ecosystem processes have been altered, site restoration likely will require both control of the invader(s) and recovery of processes. Expand
Impacts of biological invasions on disturbance regimes.
TLDR
There is now evidence that alteration of disturbance regime may be the most profound effect that a species or functional group can have on ecosystem structure and function. Expand

TLDR
The null models indicated that competition was not the major structuring force, so it is likely the assemblages are structured through a combination of morphological specialization, predation, and some competition. Expand
Lack of native species recovery following severe exotic disturbance in southern Californian shrublands
TLDR
Non-native annual communities observed in this study did not recover to a predisturbed state within typical successional time (< 25 years), supporting the hypothesis that altered stable states can occur if a community is pushed beyond its threshold of resilience. Expand

Fluctuating resources in plant communities: a general theory of invasibility
TLDR
It is concluded that the elusive nature of the invasion process arises from the fact that it depends upon conditions of resource enrichment or release that occur only intermittently and, to result in invasion, must coincide with availability of invading propagules. Expand

Invasions by non-indigenous species (NIS) are recognized as important stressors of many communities throughout the world. Here, we evaluated available data on the role of NIS in marine and estuarineExpand
Biological invasions of nature reserves: A search for generalisations
TLDR
All nature reserves, except those in Antarctica, appear to have invasive species, and management priority has to be given both to invasive species that threaten endemic species with extinction and to species that have a strong landscape effect. Expand
EXPOSING THE MECHANISM AND TIMING OF IMPACT OF NONINDIGENOUS SPECIES ON NATIVE SPECIES
TLDR
This work combined detailed, quan- titative field data on this invader and its interactions with the native snail in an individual- based model that allowed it to address both general questions about the mechanism of displacement of native species and more specific concerns about detecting the trajectory and impact of the invasion.
