Invasive plant ecology

"Preface Invasion is not a novel phenomenon; however, it is one that has increased tremendously during the past few years due to rapidly expanding trade and transport among countries. It is one of the most important impact humans have ever produced on the earth's ecosystems. In fact, it has led to globalization of world biota, further resulting in biotic homogenization. While some argue that invasion biologists should adopt a more objective and dispassionate stance towards invasive species, everyone agrees that it is a problem that needs attention and action. Recognizing that a deeper understanding of biological characteristics of invasive species and the ecological principles that underpin the invasion process is critical in formulating management decisions, the scientific community has dome an exemplary job in publishing original research as well as synthesis articles on the subject in recent years. Unfortunately, the science is still lagging behind, necessitating a reactive rather than a proactive response to the problem. The body of knowledge is growing so fast, including our ability to predict invasions. This will accelerate the science-based decision making, whether it is for
