Research Interests
Students and postdoctoral students in my laboratory work on a broad range of theoretical and applied questions in population biology (ecology, epidemiology, evolution) and social behavior.

Current Projects
At this time projects in my laboratory include:
(i) A GIS and population ecology analysis of census data from the Kruger National Park in South Africa
(ii) Modeling the interaction between elephants and vegetation in the Kruger National Park
(iii) A comparative study of the social impacts of transboundary natural resource management in southern Africa
(iv) The effects of reintroduced wolves on scavenger complexes in the Yellowstone Park ecosystem
(v) Kinship and rearing behavior in the elephants of Samburu, Kenya
(vi) Epidemiological aspects of bovine tuberculosis in Kruger Park buffalo
(vii) Sexual networks and the spread of AIDS, particularly in southern Africa
(viii) The application of network theory to understanding spatial and transmission related components of epidemics.

Abstract

The development of new telemetry and computer mapping technologies are facilitating the collection and management of large ecological data sets pertaining to the movement of individuals and the heterogeneity of populations over time and space. Here I present two new methods for analyzing such data: the first a generalization of the pair-wise correlation of two measurements to n measurements in time or over space (Getz 2003), and the second a new method for constructing home ranges or population utilization distributions on a landscape (Getz and Wilmers, 2004). I then apply these techniques to an analysis of social structure in elephants (Wittemyer et al, in press), and to interpreting movement patterns of wolves in Yellowstone National Park, USA, as well as the distribution of ungulates in the Kruger National Park, South Africa.
