“…Our study indicates that, depending on context, some of the traits conferring invasiveness, namely life form and height of the invader correspond to traits regarded as potentially influencing invasion success (Pyšek & Richardson, ). However, due to the constraints resulting from the different nature of studies examining invasion success (Pyšek et al ., , ), the compatibility of traits conferring invasiveness and impact cannot yet be assessed and research that would specifically address correspondence between the two consequences of plant introduction is much needed (Hulme, , ). If both invasiveness and impact are associated with a similar suite of traits, the body of information available from screening systems addressing invasiveness (e.g.…”

With the growing body of literature assessing the impact of invasive alien plants on resident species and ecosystems, a comprehensive assessment of the relationship between invasive species traits and environmental settings of invasion on the characteristics of impacts is needed. Based on 287 publications with 1551 individual cases that addressed the impact of 167 invasive plant species belonging to 49 families, we present the first global overview of frequencies of significant and non-significant ecological impacts and their directions on 15 outcomes related to the responses of resident populations, species, communities and ecosystems. Species and community outcomes tend to decline following invasions, especially those for plants, but the abundance and richness of the soil biota, as well as concentrations of soil nutrients and water, more often increase than decrease following invasion. Data mining tools revealed that invasive plants exert consistent significant impacts on some outcomes (survival of resident biota, activity of resident animals, resident community productivity, mineral and nutrient content in plant tissues, and fire frequency and intensity), whereas for outcomes at the community level, such as species richness, diversity and soil resources, the significance of impacts is determined by interactions between species traits and the biome invaded. The latter outcomes are most likely to be impacted by annual grasses, and by wind pollinated trees invading mediterranean or tropical biomes. One of the clearest signals in this analysis is that invasive plants are far more likely to cause significant impacts on resident plant and animal richness on islands rather than mainland. This study shows that there is no universal measure of impact and the pattern observed depends on the ecological measure examined. Although impact is strongly context dependent, some species traits, especially life form, stature and pollination syndrome, may provide a means to predict impact, regardless of the particular habitat and geographical region invaded.

“…Because of the important role that humans play in spreading invasive species, agencies have begun to develop procedures and policies that attempt to prevent further introductions (Hulme, 2011). Nevertheless, humans may affect non-native species distributions and impacts in the future by other indirect means, including global climate change, land use conversion, and pollution (Dullinger et al, 2013).…”

Humans have effectively transported thousands of species around the globe and, with accelerated trade; the rate of introductions has increased over time. Aquatic ecosystems seem at particular risk from invasive species because of threats to biodiversity and human needs for water resources. Here, we review some known aspects of aquatic invasive species (AIS) and explore several new questions. We describe impacts of AIS, factors limiting their dispersal, and the role that humans play in transporting AIS. We also review the characteristics of species that should be the greatest threat for future invasions, including those that pave the way for invasions by other species (''invasional meltdown''). Susceptible aquatic communities, such as reservoirs, may serve as stepping stones for invasions of new landscapes. Some microbes disperse long distance, infect new hosts and grow in the external aquatic medium, a process that has consequences for human health. We also discuss the interaction between species invasions and other human impacts (climate change, landscape conversion), as well as the possible connection of invasions with regime shifts in lakes. Since many invaders become permanent features of the environment, we discuss how humans live with invasive species, and conclude with questions for future research.

“…Another property of dynamic modeling is its ability to follow and model the diffusion process and not only its results, as opposed to just focusing on the final maps of potential distribution at equilibrium when using niche modeling. A dynamic approach allows predicting and understanding invasion pathways, enabling the design and prioritization of strategies to control the spread of invasive alien species into their non‐native ranges (Hulme , ). Furthermore, because the state of the biological system is modeled explicitly, sites being colonized or not over time can be predicted as a function of different factors.…”

“…However, despite a few successful results almost exclusively in islands (Veitch and Clout ), it is now widely accepted that eradication over large areas is extremely difficult when species have been established for a long time and have already modified the ecosystem (Vilà et al , Simberloff et al ). The alternate approach consists of predicting and understanding invasion pathways and processes in order to prioritise strategies to control the arrival and spread of invasive alien species into their invaded ranges (Hulme , ).…”

Species distribution models (SDM) have often been used to predict the potential ranges of introduced species and prioritize management strategies. However, this approach assumes equilibrium between occurrences and environmental gradients, an assumption which is violated during the invasion process, where many suitable sites are empty because the species has not yet reached them. Here we considered the invasive ladybird Harmonia axyridis as a case study to show the benefits of using a dynamic colonization-extinction model that does not assume equilibrium. We used a multi-year occupancy model incorporating environmental, anthropogenic and neighborhood effects, to identify factors that explained spreading variation of this species in France from 2004, when only a few occupied sites were detected, to 2011. We found that anthropogenic factors (urbanization, agriculture, vineyards, and presence/absence of highways) explained more variation in the diffusion process than environmental factors (winter and summer temperatures, wind-speed, and rainfall). The surface of urbanization was the major anthropogenic factor increasing the probability of colonization. The average summer temperature was the main environmental factor affecting colonization, with a negative effect when high or low. The neighborhood effect revealed that colonization was mostly influenced by contributions coming from a radius of 24 km around the focal cell. The contribution of neighborhood decreases over time, suggesting that H. axyridis is reaching its equilibrium in France. This is confirmed by the small discrepancy observed between the performance of our approach and a SDM approach when predicting a single year occupancy pattern at the end of the study period. Our approach has the advantage of explicitly modelling the state of the biological system during the spatial expansion and identifying colonization constraints. This allows managers to explore the effect of different actions on the system at key moments of the invasion process, hence providing a powerful approach to prioritize management strategies
