Abstract:

Under global change, the variations of resources such as nutrients and water are not stabilized and often occur in the form of pulses with low frequency, large amplitude, and short duration. The existing evidence suggests that resource pulses have the potential to disrupt the inherent equilibrium of plant communities, and thereby play a critical role in another important component of global change, plant invasion. To date, studies on the impacts of global change on plant invasion have mainly focused on the constant changes of resources, but have ignored the resource fluctuation, in particular the role of resource pulses. Here, we present a literature review concerning the effects of resource pulses on plant invasion, including causes, types and impacts of resource pulses. Then we discuss the importance of resource pulses in plant invasion. Furthermore, our review puts forward some fields that are worthy to be paid more attention in the future, such as the importance of attributes and types of resource pulses, their interactive impacts on and potential mechanisms in plant invasion.

Key words: global change, biological invasion, invasive plant, resource availability, resource fluctuation, resource pulse
