1. A large number of alien plant species have been introduced as
ornamental garden plants to Europe, but relatively few have become
invasive. Low climatic suitability may be limiting the current invasion
potential of many alien ornamental species. However, with ongoing
disturbance and climate change, this barrier may be reduced for some
species. 2. Here we tested how colonization ability (a prerequisite for
invasion) of frequently planted alien ornamentals depends on disturbance
and heating, and on their species characteristics. We sowed seeds of 37
non-naturalized alien herbaceous garden-plant species into native
grassland plots with and without disturbance, and with and without
infrared heating lamps. To assess whether their responses differ from
those within the regional wild flora, we also sowed 14 native species and
12 naturalized alien species. During two years, we assessed the
likelihoods of germination, first-year survival, second-year survival and
flowering of these 63 study species. 3. The heating treatment, which also
reduced soil moisture, decreased all measures of colonization success, but
more so for sown native species than for the non-naturalized and
naturalized alien ones. The disturbance treatment increased colonization
success, and because heating decreased productivity of the undisturbed
grassland plots, it also increased invasibility of these plots. Average
colonization success of non-naturalized aliens was reduced by heating, but
some species were not affected or performed even better with heating,
particularly those with an annual life span and a high seed mass. Winter
hardiness improved colonization ability of non-naturalized aliens, but
this advantage was reduced in the heated plots. 4. Synthesis. Disturbance
increased and heating decreased the absolute colonization success of most
of the 63 species sown. However, heating had stronger adverse effects on
the resident grassland and sown native species than either type of sown
alien species. Together, these results suggest that some alien plants may
have greater colonization success relative to native plants under a warmer
climate.
