Enhancement of plant diversity via the Janzen-Connell mechanism is often measured relative to neutral models that ignore species' competitive differences. Recent modelling indicates this mechanism is ineffective when included in models incorporating species' demographic variations. This suggests we have been asking the wrong questions when measuring the effectiveness of diversity-enhancing mechanisms.
通过 Janzen-Connell 机制增强植物多样性通常相对于忽略物种竞争差异的中性模型进行测量。最近的模型表明，当将物种的人口统计变化纳入模型时，这种机制是无效的。这表明我们在衡量增强多样性机制的有效性时问错了问题。
