Where a species lives - its geographic range - is affected by climate and the interactions it has with other living organisms. There is a complex set of factors that influence species ranges, and how these factors change with respect to changing environments depends on the life history stage of long-lived organisms, such as trees. Range shifts in plants that occur through differential mortality versus recruitment are complex processes, requiring long term data on the demography of both adults and the early stages of development for proper predictive modelling. This research replaces descriptive studies with a mechanistic understanding of species and ecosystem responses to environmental changes along elevation gradients by combining long-term field data with state-of-the-art demographic and environmental modeling. The results will advance our understanding of species range shifts, which is important to land managers and species conservation efforts. The study will also train US undergraduate and graduate students in STEM disciplines, and advance K-12 education.This research advances mechanistic knowledge of species- and ecosystem-level responses to environmental changes based on structural and chemical functional traits. Data gathered from field plots are coupled with advanced demographic modelling and airborne and satellite remote sensing to understand how the environment controls tropical forest species distributions, community composition, and ecosystem ecology. The research approach couples a large, traditional data set of forest plot inventories, which includes high precision and high temporal resolution growth and mortality data, with meteorology, structural and chemical traits, and remote sensing. A series of hypotheses centered on linking vital rates to species responses to ongoing and episodic environmental variability, as well as scaling individual species responses to ecosystem performance and function will be addressed with this research. The research centers on questions of tree distributional ecology, demography, and forest ecosystem ecology requiring long time-series to understand effects of ongoing environmental change and to detect responses to transient environmental change. Mechanistic answers to these questions in systems of long-lived organisms, such as trees, require understanding variation in vital rates conditional on environmental variables, which in turn require long time periods for accurate estimation.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

物种居住的地方（其地理范围）受气候及其与其他生物体的相互作用的影响。 有一系列复杂的因素影响物种范围，而这些因素在不断变化的环境方面如何变化取决于长寿命生物的生活历史阶段，例如树木。通过差异死亡率与招聘发生的植物的范围变化是复杂的过程，需要关于成人人口统计学和发展早期阶段的长期数据，以进行适当的预测建模。这项研究通过将长期现场数据与最先进的人口统计和环境建模相结合，以对物种对环境变化的机械理解和生态系统对环境变化的反应取代描述性研究。结果将提高我们对物种范围变化的理解，这对于土地管理者和物种保护工作非常重要。这项研究还将在STEM学科中培训我们的本科生和研究生，并提高K-12教育。这项研究促进了基于结构和化学功能性状的对环境变化的物种和生态系统级别的机理知识。 从现场图收集的数据与先进的人口统计建模以及空中和卫星遥感，以了解环境如何控制热带森林物种分布，社区组成和生态系统生态学。该研究方法将大量的传统数据集融合在一起，其中包括高精度和高时间分辨率的增长和死亡率数据，以及气象，结构和化学特征以及遥感。这项研究将解决一系列的假设，这些假设将重要率与种类对正在进行的环境变异性的响应以及对生态系统性能和功能的单个物种响应进行扩展。 该研究集中在树木分布生态，人口统计学和森林生态系统生态学问题上，需要长时间的系列来了解持续的环境变化的影响，并检测对瞬时环境变化的回答。在长寿命生物体的系统中，对这些问题的机械答案，例如树木，需要理解以环境变量为条件的生命率的变化，这又需要长时间才能进行准确的估计。该奖项反映了NSF的法定任务，并被认为是通过基金会的智力和更广泛影响的评估来评估的支持，并被认为是值得的。
