Globally, invasions by alien plants are rapidly increasing in extent and severity, leading to
large-scale ecosystem degradation. One of the most widespread invasive alien plant …

Abstract Ailanthus altissima (Miller) Swingle (family Simaroubaceae), commonly known as
the 'Tree of Heaven', grows aggressively in harsh environments where it invades …

The success of some invasive tree species is attributed, in part, to high fecundity in the form
of sexual propagules. If invasive trees produce more seed annually than co-occurring native …

Tree of Heaven (Ailanthus altissima (Mill.) Swingle) is a tree native to China which has
invaded disturbed areas in many regions worldwide. Its presence endangers natural …

The invasion of alien plant species outside of their home range constitutes an emerging
problem threatening native plant diversity. The expansion of alien species is often favored in …

Ailanthus altissima and Robina pseudoacacia are two successful invasive species of
floodplains in central Spain. We aim to explain their success as invaders in this habitat by …

Dispersal is a key process in plant invasions and is strongly related to diaspore morphology.
Often, dispersal comprises more than one step, and morphologies adapted to a primary …

Successional tree species often form soil seedbanks, suggesting that extended seed
dormancy may also facilitate regeneration in nonnative species. We examined seed …

Abstract Background and Aims Assessing the demographic consequences of genetic
variation is fundamental to invasion biology. However, genetic and demographic …

We compared potential germination success (ie, percentage of produced seeds that
germinate under optimal conditions), the percentage of empty and insect‐damaged seeds …
