| Abstract |
Biotic resistance, the reduction in invasion success
caused by native communities, plays an important role in the long-term
dynamics of biological invasions. A large body of empirical research on
biotic resistance has accumulated since the last comprehensive review on
the subject 20 years ago, enabling us to achieve a refined
understanding of biotic resistance and its dynamics. Here, we aim to
reshape research on biotic resistance to alien plant invasions by (i) synthesizing existing evidence on biotic resistance and (ii)
exploring the so far rarely considered interplay between biotic
resistance mechanisms (i.e. competition, aboveground and belowground
antagonisms, and diversity–invasibility effects) and the potential
eco-evolutionary changes in biotic resistance over time. To address the
first aspect, we conducted a global meta-analysis of 240 experimental
studies to assess the mechanisms by which and the extent to which biotic
resistance of native communities affects the performance of alien plant
species. We show that competition with native plant species,
aboveground antagonism (e.g. herbivores) and diversity–invasibility
effects significantly reduced alien plant performance, whereas there was
no evidence for consistent effects of belowground antagonism (e.g. soil
pathogens). Competition exerted the strongest biotic resistance,
followed by aboveground antagonism. However, the strength of biotic
resistance also depended on the alien plant performance measure
considered (vegetative performance, survival, reproductive performance,
or population growth). From the small set of studies that considered
more than one biotic resistance mechanism, we did not detect an overall
synergistic effect of combined mechanisms. The meta-analysis results
also revealed that biotic resistance first decreased with the residence
time of the alien plant species but increased again after approximately
200 years. In a subset of studies directly comparing species of
different origin, we did not detect a difference in biotic resistance to
alien versus native species. To address the second aspect, we
expanded the limited empirical evidence on temporal dynamics by
presenting a conceptual causal network and an accompanying mathematical
model to explore the eco-evolutionary dynamics of biotic resistance
mechanisms. Our conceptual and mathematical models highlight that biotic
resistance is determined by both the attributes of the alien species
(i.e. invasiveness) and of the recipient community (i.e. invasibility).
Both factors can change over time as inter- and/or intraspecific
selection cause changes in the composition and overall density of the
native community and the alien species. As invaders evolve and the
successful ones persist, biotic resistance initially decreases, then
increases again due to intra- and interspecific adaptation of the native
community. Using the findings from the comprehensive synthesis of
empirical studies and our modelling approach, we highlight research
avenues to better understand the temporal dynamics of biotic resistance
to plant invasions, including how biotic resistance depends on multiple
mechanisms and performance measures, how it may differently affect alien
versus native species and crucially, how it changes over time. |
