Abstract

Life history strategies, which combine schedules of survival, development, and reproduction, shape how natural selection acts on species' heritable traits and organismal fitness. Comparative analyses have historically ranked life histories along a fast-slow continuum, describing a negative association between time allocation to reproduction and development versus survival. However, higher-quality, more representative data and analyses have revealed that life history variation cannot be fully accounted for by this single continuum. Moreover, studies often do not test predictions from existing theories and instead operate as exploratory exercises. To move forward, we offer three recommendations for future investigations: standardizing life history traits, overcoming taxonomic siloes, and using theory to move from describing to understanding life history variation across the Tree of Life.

生命历程并非只有快慢之分。
生命史策略结合了生存、发育和繁殖的时间安排,决定了自然选择如何作用于物种的遗传性状和生物体的适应性。比较分析历来将生命史划分为快慢连续统一体,描述了生殖和发育时间分配与生存时间分配之间的负相关。然而,质量更高、更有代表性的数据和分析表明,生命史的变异不能完全由这一单一的连续统一体来解释。此外,这些研究往往没有检验现有理论的预测,而是作为探索性工作进行。为了向前迈进,我们为未来的研究提出了三项建议:生命史特征标准化、克服分类学孤岛以及利用理论从描述生命之树的生命史变异到理解生命之树的生命史变异。

期刊介绍: Trends in Ecology & Evolution (TREE) is a comprehensive journal featuring polished, concise, and readable reviews, opinions, and letters in all areas of ecology and evolutionary science. Catering to researchers, lecturers, teachers, field workers, and students, it serves as a valuable source of information. The journal keeps scientists informed about new developments and ideas across the spectrum of ecology and evolutionary biology, spanning from pure to applied and molecular to global perspectives. In the face of global environmental change, Trends in Ecology & Evolution plays a crucial role in covering all significant issues concerning organisms and their environments, making it a major forum for life scientists.
