Alberti - 9875041. Urbanization is a pervasive, widely distributed process that is occurring widely throughout the world. Urban development has wide ranging impacts on the occurrence of natural habitats, energy flow and nutrient cycling. Understanding these effects of ecosystem characteristics is critical for human well being and the persistence of natural and human-effected ecosystems. This project involves an empirical investigation of the effects of urban development patterns on ecological conditions in the Greater Seattle Area. It focuses on population and community dynamics of native and introduced organisms. It will examine urban development and its impact on an urban to rural gradient in Greater Seattle. The central hypothesis is that ecological conditions in an urban-to-rural gradient are influenced by urban form, land-use intensity, land-use heterogeneity, and cover connectivity. It will be tested for bird, plant, and aquatic-macroinvertebrate communities.

阿尔伯蒂9875041 城市化是一个普遍、广泛分布的进程，正在世界各地广泛发生。 城市发展对自然生境的形成、能量流动和养分循环有着广泛的影响。 了解生态系统特征的这些影响对于人类福祉以及自然和人为影响的生态系统的持久性至关重要。 该项目涉及大西雅图地区城市发展模式对生态条件影响的实证调查。 它侧重于本地和引进生物的种群和群落动态。 它将研究城市发展及其对大西雅图城市到农村梯度的影响。 核心假设是，生态条件在城市到农村梯度的城市形态，土地利用强度，土地利用异质性和覆盖连接的影响。 将对鸟类、植物和水生大型无脊椎动物群落进行测试。
