Ecological significance of plant biomass turnover

植物物种的分布主要取决于它们科普不同生境的环境条件的能力，例如养分、水和光的供应。植物获得这些资源的能力在这方面是一个重要的和充分研究的性状。同样重要但研究较少的是植物避免失去曾经获得的资源的能力，即，其周转率。资源获取与生长速率密切相关，资源损失与叶、根的寿命密切相关。生长速度和器官寿命之间通常存在反向关系：快速生长的植物通常产生寿命短的叶子和根。这个项目涉及的基本问题，生态和进化机制方面的营业额，但它也可能是重要的了解土地利用和气候变化的后果。

The distribution of plant species is largely determined by their ability to cope with the environmental conditions in different habitats, such as the availability of nutrients, water and light. A plant's ability to acquire these resources is in this respect an important and well-studied trait. Equally important, but less studied, is the plant's ability to avoid losses of the once acquired resources, i.e., its turnover rate. Resource acquisition is closely related to growth rate, resource loss with life spans of leaves and roots. There is generally a reverse relationship between growth rate and organ life span: fast-growing plants usually produce short-lived leaves and roots. This projects concerns basic questions about ecological and evolutionary mechanisms with respect to turnover, but it is also potentially important for understanding the consequences of changes in land use and climate.
