Research Interests: While my research interests are diverse, they can be divided into two broad categories: (i) arid ecosystem ecology and conservation and (ii) the behavioral ecology of information use. Much of my work in arid ecosystems has examined desertification and factors that affect the biodiversity. I am particularly interested in livestock effects on soil chemical and physical processes that then affect plant and animal populations. My examination of behavior is frequently centered on understanding how animals perceive their environment. Much of my behavioral work examines information use in social animals who differ from solitary individuals in that they can acquire public information to estimate the quality of resources by noting the activities of other individuals.

Research opportunities: I seek dedicated students interested in 1) desertification and plant ecology, or 2) public information use in animals. Please see my papers below and contact me (Valone@slu.edu) for further information.
