What determines invasiveness of alien organisms is among the most interesting and urgent questions in ecology. In attempts to answer this question, researchers compare invasive alien species either to native species or to non-invasive alien species, and this is done in either the introduced or native ranges. However, inferences that can be drawn from these comparisons differ considerably, and f...
The ability to predict which alien plants will transition from naturalized to invasive prior to their introduction to novel regions is a key goal for conservation and has the potential to increase the efficacy of weed risk assessment (WRA). However, multiple factors contribute to plant invasion success (e.g., functional traits, range characteristics, residence time, phylogeny), and they all mus...
Invasive alien plants (IAPs) pose a significant threat to the ecological environment and agricultural production in China. Ageratina adenophora is one of most aggressive IAPs China poses serious socioeconomic threats. Estimating distribution pattern A. can provide baseline data for preventing damage by this weed. In present study, based on equilibrium occurrence related environmental variables,...

Oxalis pes-caprae f. pleniflora (Lowe) Sunding (Oxalidaceae), a naturalized invasive alien is recorded for the first time from Turkey. It has staminodes and double petals as different properties from Oxalis pes-caprae L. Sympatric variations occured in the species populations could be the result of an accumulation of mutations or genome rearrangement. Invasive alien weed Oxalis pes-caprae and i...
In a recent Opinion article in TREE [1], Gurevitch and Padilla concluded that the importance of invasive species in causing declines and extinctions of species is unproven. They analyzed the IUCN Red List database [2] and stated that only 6% of the taxa are threatened with extinction as a result of invasion by alien species and !2% (ten terrestrial plants and no animal species) of the 762 extin...
versity through genetic drift, founder effects, and genetic bottlenecks. Such events can reduce a population’s evolutionary potential and increase the risk of extinction. In this chapter, we use plant immigrants as a model system to examine the circumstances in which genetic bottlenecks do (and do not) occur and where in the hierarchical partitioning of genetic diversity such bottlenecks take p...
Invasive plant species are among the major threats to freshwater biodiversity. Few experimental studies have investigated whether native plant diversity can provide biotic resistance to invaders in freshwater ecosystems. At small spatial scales, invasion resistance may increase with plant species richness due to a better use of available resources, leaving less available for a potential invader...
Trait-based approaches are widely used in community ecology and invasion biology to unravel underlying mechanisms of vegetation dynamics. Although fundamental trade-offs between specific traits and invasibility are well described among terrestrial plants, little is known about their role and function in aquatic plant species. In this study, we examine the functional differences of aquatic alien...
