The research proposed will focus on a mechanistic model for understanding simultaneous heat and water fluxes in porous media such as fur, feathers or grasses or crops in outdoor environments. Understanding heat and water fluxes is important because they are a critical part of an animal's capacity to grow and reproduce. Without a mechanistic understanding of these fluxes, empirical measurements must be made for each new situation. This work is important because it will lead to understanding animal population and community dynamics and to understanding the influences of multiple low level stresses, such as climate, disease and toxicants on those dynamics. It also provides a fundamental basis for developing general microclimate models for grasses and crops, which are "home" (constitute the microenvironments) for small vertebrates and invertebrates. Results from this research can also be applied to: 1) assessment of impact of climate change on animal growth and reproduction potential; 2) assessment of genetic engineering of changes in animal allometry of fur properties as it affects feed efficiency for production of milk or meat; 3) assessment of different, more energy efficient domestic animal housing in different climates; 4) understanding aspects of the limits to animal distributions and how they might change for different climate change scenarios; 5) assessment of the impact of infectious diseases and low level toxicants on capacity of animals to grow and reproduce in different environments.

拟议的研究将集中在一个机械模型， 了解多孔介质中的同时热通量和水通量 例如毛皮、羽毛或草或户外作物 环境. 了解热通量和水通量很重要 因为它们是动物生长能力的关键部分 并繁衍后代 如果没有机械地理解这些 通量，经验测量必须对每个新的 形势 这项工作很重要，因为它将导致 了解动物种群和群落动态， 了解多个低水平应力的影响，例如 气候、疾病和有毒物质对这些动力学的影响。 它还 为发展总体小气候提供了基础 草和作物的模型，这是“家”（构成 微环境）的小型脊椎动物和无脊椎动物。 本研究的结果也可应用于：1） 评估气候变化对动物生长的影响， 繁殖潜力; 2）评估基因工程 动物皮毛特性的异速生长变化对饲料的影响 生产牛奶或肉类的效率; 3）评估 不同的，更节能的家畜住房， 不同的气候; 4）了解限制的方面， 动物的分布以及它们在不同的 气候变化情景; 5）评估气候变化的影响 传染病和低水平的有毒物质的能力， 动物在不同的环境中生长和繁殖。
