Recent years have seen a surge of interest in understanding patterns and processes of plant
invasions into mountains. Here, we synthesise current knowledge about the spread of non …

Invasion science is a very active subdiscipline of ecology. However, some scientists contend
that theoretical integration has been limited and that predictive power remains weak. This …

Nonnative species richness typically declines along environmental gradients such as
elevation. It is usually assumed that this is because few invaders possess the necessary …

Aim Climate change has increased the risk of biological invasions, particularly by increasing
the climatically suitable regions for invasive alien species. The distribution of many native …

Our ability to predict invasions has been hindered by the seemingly idiosyncratic context-
dependency of individual invasions. However, we argue that robust and useful …

Mountain ecosystems have been less adversely affected by invasions of nonnative plants
than most other ecosystems, partially because most invasive plants in the lowlands are …

Invasion by alien species is a global problem and forms one of the major drivers of global
change. The researches on plant invasion have grown rapidly across the globe since the …

Prevention is regarded as a cost-effective management action to avoid unwanted impacts of
non-native species. However, targeted prevention can be difficult if little is known about the …

Until now, nonnative plant species were rarely found at high elevations and latitudes.
However, partly because of climate warming, biological invasions are now on the rise in …

Aim To investigate how species richness and similarity of non‐native plants varies along
gradients of elevation and human disturbance. Location Eight mountain regions on four …
