One of the central problems facing biology is to identify the generalprinciples that govern the evolution of form, function and diversity.Adding to this problem is the complexity of connecting pattern and processacross several scales of biological organization. The career developmentplan will allow for the development of a rigorous integrative trainingprogram in biological scaling at the University of Arizona. The proposedresearch program consists of two parts: 1) Expand a general allometricframework to account for patterns of ontogenetic growth across vascularplants. This focus will provide theoretical extensions and empiricalassessments of allometric theory to account for patterns of ontogeneticgrowth and allocation across vascular plants; 2) Extend theoreticalframework to quantitatively predict how physiological aspects of plantsand variation in allocation and growth rate ramify to influence numerousattributes of large-scale dynamics in ecological communities andecosystems. This line of investigation is geared toward: (i) documentingprominent scaling laws associated with the production and allocation ofbiomass across ecological communities; (ii) elucidating how theconstraints of plant allometry influences the size structuring anddynamics of ecological communities; and (iii) highlighting a novel theoryfor the movement of resources and energy through ecosystems. Themultifaceted research proposed will combine elaboration of allometrictheory, the compilation of large global datasets, and experimentalgreenhouse manipulations to assess the quantitative predictions of newtheoretical insights. The proposed research will contribute to asignificant advancement in our ability to mechanistically predict thescaling of pattern and process in biology.

生物学所面临的一个中心问题是确定支配形式、功能和多样性进化的一般原则。除此之外，在生物组织的几个尺度上连接模式和过程的复杂性也增加了这个问题。职业发展计划将允许亚利桑那大学在生物缩放方面制定严格的综合培训计划。该研究计划包括两部分：1）扩展一个通用的异速生长框架来解释维管植物的个体发育生长模式。这一重点将提供异速生长理论的理论扩展和分析评估，以解释维管植物的个体发育生长和分配模式; 2）扩展理论框架，以定量预测植物的生理方面以及分配和生长速率的变化如何影响生态群落和生态系统中大尺度动态的众多属性。 这条调查线是面向：（i）documentingprominent标度律与生产和分配的生物量在生态群落;（ii）阐明植物异速生长的约束如何影响生态群落的大小结构和动态;（iii）突出一个新的理论，通过生态系统的资源和能量的运动。 多方面的研究建议将结合联合收割机阐述异速生长理论，汇编大型全球数据集，和实验温室操作，以评估新的理论见解的定量预测。拟议中的研究将有助于我们在机械上预测生物学中模式和过程的尺度的能力的重大进步。
