植物功能性状与种群表现之间的关系构成了基于性状的生态学的基础。它也是基于特征的生态学和许多进化生物学之间的自然联系。尽管这些重要的方面，植物性状的人口统计性能的关系，在文献中报道的通常是薄弱或不存在的，以及性状如何与生态和进化模式的合成图片仍然不发达。在这里，我们开始提出一个概述的缺点，在功能性特质人口绩效研究和为什么弱的结果比基于特质的生态学家更常见喜欢承认。然后，我们讨论为什么应该有一个自然的合成之间的基于特征的生态学和进化生态学和潜在的原因，为什么这种合成尚未出现。最后，我们提出了一系列的概念和经验的焦点，应纳入未来的特质人口绩效的研究，希望巩固的基础，基于特质的生态学和催化与进化生态学的合成。这些措施包括：（1）把个体作为研究的基本单位，而不是依赖于种群或物种的性状和人口统计率的平均值;（2）更加重视表型整合，替代设计和性能景观;（3）接受区域和当地规模的环境对植物性能的重要性;（4）了解生命阶段转变的不同驱动因素，以及功能的哪些方面应该与这些转变相关联;（5）确定植物死亡的驱动因素如何独立和协调地起作用，以及植物功能的哪些方面最能预测这些结果。我们的目标是帮助突出特点人口学表现研究的缺点，因为它的立场和领域，这项研究当然可以正确的，最终，希望促进一个基于特点的研究计划，既讲生态学家和进化生物学家。
The relationship between plant functional traits and demographic performance forms the foundation of trait-based ecology. It also serves as the natural linkage between trait-based ecology and much of evolutionary biology. Despite these important aspects, plant trait–demographic performance relationships reported in the literature are typically weak or nonexistent, and a synthetic picture of how traits are related to ecological and evolutionary patterns remains underdeveloped. Here, we begin by presenting an overview of the shortcomings in functional trait–demographic performance research and why weak results are more common than trait-based ecologists like to admit. We then discuss why there should be a natural synthesis between trait-based ecology and evolutionary ecology and potential reasons for why this synthesis has yet to emerge. Finally, we present a series of conceptual and empirical foci that should be incorporated into future trait–demographic performance research that will hopefully solidify the foundation of trait-based ecology and catalyze a synthesis with evolutionary ecology. These include (1) focusing on individuals as the fundamental unit of study instead of relying on population or species mean values for traits and demographic rates; (2) placing more emphasis on phenotypic integration, alternative designs, and performance landscapes; (3) coming to terms with the importance of regional- and local-scale context on plant performance; (4) an appreciation of the varied drivers of life-stage transitions and what aspects of function should be linked to those transitions; and (5) determining how the drivers of plant mortality act independently and in concert and what aspects of plant function best predict these outcomes. Our goal is to help highlight the shortcomings of trait–demographic performance research as it stands and areas where this research could course correct, ultimately, with the hope of promoting a trait-based research program that speaks to both ecologists and evolutionary biologists.
