Research Associate (STEP 2004-2006)

My research concerns the distribution of species and of species diversity in space, from local to global scales. Based on this work, I explore methods for sustaining and restoring nature. At Princeton, David Wilcove and I are assessing the state of imperiled species in Florida's Lake Wales Ridge. Within this ecosystem, we are developing decision tools for more efficient allocation of management actions given scarce resources. Elsewhere, I have found human-dominated areas to be both fertile ground for basic research and critical targets for successful conservation. As a Ph.D. student at the University of Arizona, I created the Tucson Bird Count (tucsonbirds.org), an ongoing, community-based program which monitors birds at more than 1000 sites in the Tucson area. There, I modeled the scale-dependent relationships between bird species and their habitats in fragmented landscapes, and -- using simulation -- evaluated alternative "future Tucsons" to determine development and restoration strategies best able to sustain native birds. Other recent projects include improving methods for estimating species diversity, and understanding scale-dependence in species-area relationships.
