This proposal requests funds for multi-user analytical equipment for the University of Missouri-St. Louis plant sciences program. Five investigators require this equipment to enhance their current research programs and for future research. These researchers work in the areas of plant population genetics, plant-herbivore interactions, and plant life history. Research in these diverse areas gains a common focus through the investigators' interest in determining the selective environmental factors influencing plant development, growth, and reproductive success. The equipment requested would provide the resources for faculty and students to study patterns of plant resource allocation, plant responses to environmental variation and stress, water relations, photosynthesis, and secondary compound chemistry. Specific research projects requiring this equipment include: comparative analysis of resource allocation and growth patterns in different microhabitats in Quercus species, assessment of genotypic variation in Piper arieanum defense and tolerance resistance to herbivory, documentation of resource allocation across canopies of tropical forests and between developmental stages of seedlings in Missouri forests, resource availability in fleshy fruits and assimilation efficiencies for common understory fruit-eating bats and birds, and determination of the genetic basis of reproductive costs in Solidago. The requested equipment includes an elemental analyzer, a fluorometer and photosynthesis system, water relations instruments, environmental monitoring equipment and computer, plant growth chambers, a gas chromatograph, and an ultracold freezer.

这项提案要求为密苏里大学圣彼得堡分校的多用户分析设备提供资金。路易植物科学项目。五名研究人员需要这种设备来加强他们目前的研究计划和未来的研究。这些研究人员在植物种群遗传学、植物-食草动物相互作用和植物生活史等领域开展工作。通过研究人员对确定影响植物发育、生长和繁殖成功的选择性环境因素的兴趣，这些不同领域的研究获得了共同的关注。所需的设备将为教职员工和学生提供学习植物资源分配模式、植物对环境变化和胁迫的反应、水分关系、光合作用和次生化合物化学的资源。需要这种设备的具体研究项目包括：比较分析栎属不同微生境中的资源分配和生长模式，评估胡椒对草食性的防御和耐受性，记录热带森林树冠之间和密苏里州森林苗木不同发育阶段之间的资源分配，肉质水果的资源可用性和常见林下食果蝙蝠和鸟类的同化效率，以及确定Solidago繁殖成本的遗传基础。所要求的设备包括元素分析仪、荧光仪和光合作用系统、水分关系仪器、环境监测设备和计算机、植物生长室、气相色谱仪和超冷冷冻机。
