Research in my lab focuses on the social behavior of animals, with an emphasis on the mechanisms, development, and function of vertebrate social behavior. A second area of interest is dispersal, particularly as it relates to social structure and organization. Both of these topics are crucial to our understanding of evolution and to conservation efforts. A third and new area of research is the behavioral ecology of the brown recluse spider (Loxosceles reclusa)
In the area of social behavior, a primary interest has been communication, particularly chemical communication, in rodents and reptiles (e.g., Halpin 1986, 1990). Specifically, my research on individual odors demonstrated that mammalian odors can function in the discrimination of individuals, mates, and offspring, and other kin; they can also affect mating success and reproductive performance.
Research in my lab has also examined various aspects of kin discrimination, as well as the effects of kinship and social familiarity on social behavior and reproductive success. These studies have focused on understanding the mechanisms and development of kin discrimination and on elucidating the cues by which related individuals recognize one another (e.g., Halpin 1991, Tang-Martinez 2001).
Mammalian dispersal has been an ongoing area of interest (e.g., Chepko-Sade and Halpin 1987), and several of my students are conducting research on this topic. Dispersal patterns, including philopatry, can influence, and be influenced, by social structure and social behavior. Studies on dispersal can lead to a better understanding of mating systems and genetic structure of populations; additionally, they can be important in establishing realistic estimates of effective population size, as well as in determining genetic variability within and between populations.
At present, most of my students are conducting research on the demography, dispersal, and/or development of social behavior in various species of North American and neo-tropical mammals. Most of this research is being done in the field, but one student is working in the laboratory. Due to the high costs of animal care, and inadequate support for our animal care unit, after 2001 I will no longer accept students wishing to conduct laboratory studies on rodents.
In summer 2002, I initiated a new research project on the behavioral ecology and social behavior of brown recluse spiders (Loxosceles reclusa). These highly poisonous, but very timid spiders are extremely common in St. Louis, particularly in older houses. My research is a "field study" being conducted on a natural population of brown recluses living in the basement of my house. In addition to developing an ethogram, I am examining site fidelity, habitat preferences, population dynamics and social interactions of this terrestrial sit and wait predator.
I also have a strong interest in theoretical
issues, as well as in the philosophy and history of biology (see Braude et al. 1999; Tang-Martinez 1997, 2000, 2001, 2005).
Areas of focus are the history of biological determinism, the human sociobiology debate, ethical issues in biology, and the development of scientific ideas and paradigms.
