It is well known that climate (temperature, rain or snow) can change the timing (or "phenology") of plant and animal reproduction, and that different species vary in how much they shift their timing. Little is known about how these differences in responses to climate will influence the ability of species to thrive. When the weather becomes warmer, or snow melts earlier, do plant species that shift their flowering time earlier become more common than plants that change less? Is it possible for bees and flowers to shift their timing of reproduction differently and miss interacting? Answers to these kinds of questions are important for predicting how plants and animals in natural areas will change in the future, and for managing the crop plants we depend on for food. The project also trains elementary and high school science teachers and college students in research, and provides science talks for children and adults.The Rocky Mountain Biological Laboratory Phenology Project maintains the world's longest detailed record of the timing of plant and insect activity. These records, together with new measurements of plant growth, will be used to understand how changes in the timing of flowering and bee activity with climate affect plant and bee success. The project has detailed measurements of climate (daily) and the timing of flowering (three times per week) for all plant species in 36 permanent plots in high mountain meadows in Colorado for up to 45 years, and the abundance of all bee species (every other week) in nearby meadows for ten years. Going forward, this project will measure the relative abundance of all plant species and productivity of the plant community. With these new data, the project will address three questions: (1) Does the phenological responsiveness of plant or bee species explain differences in species' abundances, annual variation in abundance, or resilience after extreme weather events? (2) How does the phenological responsiveness of the plants used by each bee guild influence bee communities? (3) Are the traits of plants in a local community related to community-level responses to climate such as changes in species richness, or ecosystem responses such as productivity? The project will also continue to provide its long-term datasets (already used by research groups across the US and abroad) to the scientific community.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.

众所周知，气候(温度、雨或雪)会改变动植物繁殖的时机(或“物候”)，不同的物种在改变时机的程度上存在差异。关于气候反应的这些差异将如何影响物种茁壮成长的能力，人们知之甚少。当天气变暖或积雪提前融化时，花期提前的植物物种是否比变化较少的植物更常见？蜜蜂和花朵有没有可能改变它们的繁殖时机，从而错过相互作用？这类问题的答案对于预测自然区的动植物未来将如何变化以及管理我们赖以生存的农作物是很重要的。该项目还培训中小学科学教师和大学生进行研究，并为儿童和成人提供科学讲座。落基山生物实验室物候学项目保持着世界上关于植物和昆虫活动时间的最长详细记录。这些记录，连同植物生长的新测量，将被用来理解开花时间和蜜蜂活动随气候变化如何影响植物和蜜蜂的成功。该项目对科罗拉多州高山草甸36块永久性地块的气候(每天)和所有植物的开花时间(每周三次)进行了详细的测量，最长可达45年，并对附近草甸的所有蜜蜂物种(每隔一周)的丰度进行了10年的测量。展望未来，该项目将测量所有植物物种的相对丰富度和植物群落的生产力。利用这些新数据，该项目将解决三个问题：(1)植物或蜜蜂物种的物候响应性是否解释了物种丰度、丰度年度变化或极端天气事件后弹性的差异？(2)每个蜜蜂协会使用的植物的物候响应性如何影响蜜蜂群落？(3)当地社区中植物的特征是否与群落对气候的反应(如物种丰富度的变化)或生态系统反应(如生产力)有关？该项目还将继续向科学界提供其长期数据集(已被美国和海外的研究小组使用)。这一奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。
