Urban raptor population assessment for the metropolitan Phoenix area, central Arizona, 2001-2006

The spread of urbanization is inevitable in both the developed and developing nations of the world. As cities continue to spread the impact on the environment, flora and fauna of their local ecosystems increases. In a southwestern U.S. city (Phoenix, AZ), we assess the effects of urban development on the local raptor population both in terms of casualties and nesting behavior.城市化进程在全球发达国家与发展中国家均为不可避免的趋势。随着城市规模持续扩张，其对当地生态系统的环境、动植物所造成的影响日益加剧。本研究以美国西南部城市——亚利桑那州凤凰城（Phoenix, AZ）为例，从种群伤亡与筑巢行为两个维度，评估了城市开发对当地猛禽（raptor）种群的影响。
