人们有强烈的动机去预测哪些物种会在它们变得过于广泛和难以管理之前成为入侵者。在这项研究中，我们进行了多年，时间复制，温室和田间实验的基础上植物功能性状，量化竞争能力，系统发育比较，以确定入侵状态，生活史和栖息地不同的四个密切相关的物种的入侵潜力。我们的研究结果表明，这些密切相关的物种确实表现出类似的竞争能力，入侵性，而不是这些物种的生活史或栖息地似乎是竞争力的驱动因素。
There is a strong incentive to predict which species will become invasive before they become too widespread and unmanageable. In this study, we conducted a multi-year, temporally replicated, greenhouse and field experiment based on plant functional traits, quantifying competitive ability, and phylogenetic comparison to determine the invasive potential of four closely related species varying in invasion status, life history and habitat. Our results suggest that these closely related species do exhibit similar competitive abilities and that the invasiveness and not the life history or habitat of these species appear to be the driving factor of competitiveness.
