Effect of Climate Change on the Invasive Alien Plant Species

Abstract

The introduction of invasive alien plant species (IAPS), which have strong competitiveness will outcompete the native species, destroy the ecological balance and results in loss of biodiversity. Under staggering changes of climate scenarios, the damage brought by invasion could be even more unpredictably severe. To better protect the original biodiversity, possible evolution process of distribution and mechanisms of some invasive species, and some efficient approaches that could deal with invasive organisms is concluded below. The results illustrate that based on their dominant biological mechanisms, the invaded geographical regions will increase in the future and with different species, the rate of expansion may vary. The elevational changes of invaded regions will also occur due to rising temperature. With increasing rate of globalization and climate change, there will be more frequent species exchange in the future. Controlling or preventing the presence of IAPS out of natural range, especially the presence caused by anthropogenic activity will still be extremely crucial. It is also necessary to keep carrying out experiment, modelling and analysis to comprehend the nature of invasive species. The paper summarizes the possible effect and mechanisms of typical species that can be used by the authorities, in order to develop effective control and management strategies in the nearly future.
