Urban landscape patterns are emergent, coupled human-natural phenomena that epitomize the complexity of interactions and feedback mechanisms between human decisions and ecological processes (Figure 1, Alberti 2008). The process of urbanization results in a complex pattern of intermixed high- and low-density built-up areas and fragmented natural patches. Alternative urban development patterns affect ecological processes both directly—by replacing native habitat with simplified, human-dominated systems—and indirectly—by rearranging the biophysical attributes that cause a variety of interrelated local and global effects. By studying the Seattle and Phoenix metropolitan areas, Dr. Alberti and colleagues from the University of Washington and Arizona State University have started to document distinct ecological signatures of urban landscape patterns, using landscape characteristics relevant to various ecosystem processes.
