稀有性一直是保护和进化生物学家的中心话题，其最终目标是确定导致灭绝风险的物种特征。最近，除了物种的稀有性之外，功能或功能特征的稀有性（称为功能稀有性）在帮助理解生物多样性下降对生态系统功能的影响方面获得了动力。然而，定义和量化功能稀有性的概念框架仍然缺乏。在这里，我们介绍了十二种不同形式的功能稀有性沿着梯度的物种稀缺性和性状独特性。然后，我们强调功能稀有性在长期和大规模的生态系统过程的维护中的潜在关键作用，以及功能稀有性和进化稀有性之间的必要联系。
Rarity has been a central topic for conservation and evolutionary biologists with the ultimate goal of determining the species characteristics that cause extinction risk. More recently, beyond the rarity of species, the rarity of functions or functional traits, called functional rarity, has gained momentum in helping to understand the impact of biodiversity decline on ecosystem functioning. However a conceptual framework for defining and quantifying functional rarity is still lacking. Here, we introduce twelve different forms of functional rarity along gradients of species scarcity and trait distinctiveness. We then highlight the potential key role of functional rarity in the long-term and large-scale maintenance of ecosystem processes, as well as the necessary linkage between functional and evolutionary rarity.
