General Areas of Interest: Behavioral
ecology, population biology, conservation, behavioral
endocrinology, evolutionary ecology. Virtually
all of my research is based on field studies,
generally using observational methods, and often
following known individuals. Much of the work in
my lab has involved the integration of behavioral and
demographic data from the field with physiological and
genetic data from the lab. My lab is equipped
for extraction and enzyme immunoassays of steroid and
peptide hormones, microhistology and other assays.
My papers are on ResearchGate, and those from the last couple of years are listed below.

1991-1996, Nancy and I studied African wild dogs
(Lycaon pictus) in the Selous Game Reserve.
At roughly 80,000 square kilometers, the Selous is
one of the largest protected areas in the world, but its
ecology is little-studied. Our project
focused initially on simply assessing the size of the
wild dog population in Selous (a formidable task in
itself), and progressed to identifying the ecological
factors that cause wild dogs to be endangered, with
invariably low densities in comparison to other large
carnivores. In this regard, interspecific
competition plays a major role in limiting wild dog
numbers and distributions. We also used
demographic data to make quantitative assessments of
extinction risk, and collected a substantial data set on
prey selection, predator-prey interactions and the
costs/benefits of cooperative hunting. Finally we
examined social evolution and
behavioral and endocrine mechanisms of reproductive
suppression in wild dogs, in a manner similar to our
earlier work with dwarf mongooses. The major results of this work are found in
in Creel S & Creel N 2002. The African wild dog:
behavior, ecology and conservation. Princeton
