- Functional diversity metrics based on species traits are widely used to investigate ecosystem functioning. In theory, such metrics have different implications depending on whether they are calculated from traits mediating responses to environmental change (response traits) or those regulating function (effect traits), yet trait choice in diversity metrics is rarely scrutinized.
- Here, we compile effect and response traits for British bird species supplying two key ecological services—seed dispersal and insect predation—to assess the relationship between functional diversity and both mean and stability of community abundance over time.
- As predicted, functional diversity correlates with stability in community abundance of seed dispersers when calculated using response traits. However, we found a negative relationship between functional diversity and mean community abundance of seed dispersers when calculated using effect traits. Subsequently, when combining all traits together, we found inconsistent results with functional diversity correlating with reduced stability in insectivores, but greater stability in seed dispersers.
- Our findings suggest that trait choice should be considered more carefully when applying such metrics in ecosystem management.

响应和效应特征的多样性提供了与生态功能相关的鸟类群落动态的补充信息
- 基于物种特征的功能多样性指标被广泛用于调查生态系统功能。从理论上讲，这些指标具有不同的含义，具体取决于它们是从调节对环境变化的反应的性状（反应性状）还是从调节功能的性状（效果性状）计算出来的，但很少仔细审查多样性指标中的性状选择。
- 在这里，我们编制了提供两种关键生态服务（种子传播和昆虫捕食）的英国鸟类的效应和响应特征，以评估功能多样性与群落丰度随时间的平均值和稳定性之间的关系。
- 正如预测的那样，当使用响应性状计算时，功能多样性与种子传播者群落丰度的稳定性相关。然而，当使用效应性状计算时，我们发现功能多样性与种子传播者的平均群落丰度之间存在负相关。随后，当将所有性状结合在一起时，我们发现与功能多样性不一致的结果与食虫动物稳定性降低相关，但种子传播者稳定性更高。
- 我们的研究结果表明，在生态系统管理中应用此类指标时，应更仔细地考虑性状选择。
