Long-term data provide a valuable context to understand how landscapes and species adjust to variation in climate, changing land use, and a variety of disturbances. This project extends a twenty-six year study of 14 plant species by combining experiments with models to understand the effects of local and regional variation on plant population dynamics. Field experiments will vary water and ash addition and removal, competition, and seed additions. Survival, growth, fecundity, and recruitment will be measured in both undisturbed populations and experimental treatments, and these small-scale responses will then be linked with larger-scale changes in climate and fire regimes. Long-term data and experimental results will inform models that predict how different fire and climate conditions affect key plant species. In general, this research takes advantage of long-term demographic data on multiple co-occurring plant species to reveal how plants respond across different spatial scales to environmental change. The research incorporates education efforts at multiple levels. It will support high school research assistants each summer and will fund post-baccalaureate interns, continuing a unique, highly productive, in-depth research experience. Graduate students will be trained through their participation in the research. The project will provide a wealth of statistical, ecological, and conservation information, contributing directly to conservation of Florida scrub, an imperiled ecosystem that is home to dozens of endangered species. Specialized workshops and continual interaction with local land managers and policy makers through collaborations and presentations will increase the practical value of the research findings. Specifically, the project will inform land managers using fire and other tools to conserve critically threatened plants. Public displays and art projects will directly convey information to the general public.

长期数据为了解景观和物种如何适应气候变化、土地利用变化和各种干扰提供了有价值的背景。本研究延续了对14种植物26年的研究，通过实验与模型相结合，了解当地和区域变化对植物种群动态的影响。田间试验将改变水和灰分的添加和去除，竞争和种子添加。生存，生长，繁殖力和招聘将在不受干扰的人口和实验治疗，这些小规模的反应，然后将与气候和火灾制度的大规模变化。长期数据和实验结果将为预测不同火灾和气候条件如何影响关键植物物种的模型提供信息。总的来说，这项研究利用了多个共存植物物种的长期人口统计数据，揭示了植物如何在不同的空间尺度上对环境变化做出反应。 该研究纳入了多个层面的教育工作。它将支持高中研究助理每年夏天，并将资助学士学位后的实习生，继续一个独特的，高效的，深入的研究经验。研究生将通过参与研究进行培训。该项目将提供丰富的统计、生态和保护信息，直接有助于保护佛罗里达灌木丛，这是一个危险的生态系统，是数十种濒危物种的家园。专门讲习班以及通过合作和介绍与当地土地管理人员和决策者不断互动，将增加研究结果的实用价值。具体而言，该项目将告知土地管理人员使用火和其他工具来保护受到严重威胁的植物。公共展览和艺术项目将直接向公众传达信息。
