一个强有力的案例可以证明，整个生物体的性能性状（即动态的、生态相关的性状，其表达受潜在形态因素的影响）是最终的综合性状。这不仅是因为它们捕获了多个较低水平生物组织的输出，还因为它们与多种生态环境中的个体适应性直接相关，并且在许多情况下是生存和/或繁殖成功的重要近似决定因素。但是，尽管许多生态和进化现象可以通过性能的视角来检验（反之亦然），但性能研究在纳入生命史进化这一庞大而重要领域的概念方面却出奇地缓慢。这样的综合是必要的，因为资源分配策略的转变可能对这些与生态高度相关的功能性性状产生影响，这些性状的表达可能与繁殖力、免疫功能或寿命以及其他关键的生活史性状相权衡。本次研讨会上的论文展示了许多生命史策略可以直接影响整个生物体表现的表达、维持和进化的方式（至少有一种情况下它们可能不会）。通过从许多不同的角度探讨生活史权衡问题，本次研讨会揭示了未来生活史技术与生物体性能研究的明确整合的范围，以更全面地了解多变量表型进化。
A strong case can be made for whole-organism performance traits (i.e., dynamic, ecologically relevant traits whose expression is shaped by underlying morphological factors) as being the ultimate integrative traits. This is not only because they capture the output of multiple lower levels of biological organization, but also because they are directly relevant to individual fitness in multiple ecological contexts, and are in many cases important proximate determinants of survival and/or reproductive success. But although many ecological and evolutionary phenomena can be examined through the lens of performance (and vice-versa), performance research has been surprisingly slow to incorporate concepts from the large and important field of life-history evolution. Such a synthesis is necessary, because shifts in resource allocation strategies can have implications for these highly ecologically relevant, functional traits, whose expression may trade-off against fecundity, immune function, or longevity, among other key life-history traits. The papers in this symposium showcase many of the ways in which life-history strategies can have direct consequences for the expression, maintenance, and evolution of whole-organism performance (and at least one case where they may not). By approaching the issue of life-history trade-offs from a number of diverse perspectives, this symposium reveals the scope for future explicit integration of life-history techniques with those of whole-organism performance studies for a more complete understanding of multivariate phenotypic evolution.
