Research Interests:

Dr. Lombardo is interested in the evolution of behavior. His current research involves examining both theoretically and empirically the role of sexually transmitted microbes (e.g., viruses, bacteria, and fungi) in the ecological and evolutionary dynamics of mating systems. According to Dr. Lombardo, it is easy to understand the advantages that accrue to individuals that avoid copulating with partners infected with sexually transmitted pathogens. However, it is also possible for an individual, especially a female, to benefit by copulating with a partner that inoculates it with a beneficial microbe that either acts as a therapy against a current infection or as a "vaccine" against future infection. Dr. Lombardo is interested in how the relative frequencies and potencies (i.e., effects on hosts) of sexually transmitted microbes in a population affect mating behavior. He also is collaborating with Dr. Thorpe on this project. Dr. Thorpe focuses on the microbiological aspects of this question while Dr. Lombardo focuses on the behavioral aspects. 

Sport is a human universal, but has received relatively little attention from evolutionary biologists. I am currently working on a book, "A Natural History of Sports," that synthesizes information from anthropology, biology, history, psychology, sociology, and today's sports pages to explain the biological importance of this fundamental component of human nature.


 

Research Opportunities for Students:

Drs. Thorpe and Lombardo study these questions by examining the microbiology and mating behavior of Tree Swallows, a common bird on the GVSU campus. Each year they are assisted by both field and laboratory assistants. Student field assistants learn the skills necessary for conducting basic ornithological and behavioral research. Each learns how to census nest boxes, capture and color-mark wild birds, weigh and measure birds, search birds for ectoparasites (e.g., mites and lice), and take blood, semen, fecal, and cloacal samples. Under the direction of Dr. Thorpe, lab assistants learn basic microbiological techniques. They have had many students working with them in the past. Some have been quite successful and have made presentations at professional meeting and have been co-authors on papers published in scientific journals. If you are interested in participating in this project, you may contact either professor.
