Spatial Modeling


A major focus of my research is the spatial modeling of ecological systems, using computer simulation approaches. The goal of this approach is to develop an understanding of the impact of spatial interactions on the outcome of ecological processes. I have worked in a number of systems, independently and in collaboration with other scientists. The systems have included serpentine grasslands (Moloney and Levin 1996), tallgrass prairie (Klaas, Moloney and Danielson 2000), the Karoo of South Africa (Wiegand, Moloney and Milton 1998), South African savannas (Jeltsch et al. 1998, Wichmann et al. 2003), individually based models of European brown bears (Wiegand, Revilla and Moloney 2005), and most recently, a network analysis of the impact of localized control on the presistence of invasive mammals in New Zealand (Perry, Moloney and Etherington 2017). The goal of these models has been to address basic ecological questions ranging from examining the importance of the spatio-temporal architecture of disturance regimes in determining biodiversity to exploring the role of habitat fragementation on the sustainability of populations of brown bears in northern Spain.
