About Jon's Work

Jon Seger is an evolutionary ecologist who combines fieldwork with mathematical modeling to understand how natural selection and other evolutionary forces generate biological diversity at several different levels of organization.

Seger studies the evolution of various aspects of sexual reproduction, including parental investment and sex ratios, mate choice, mating systems, recombination rates, genetic imprinting, host-parasite and prey-predator interactions, and life histories.  He also has specific interests in the evolutionary ecology of Hymenoptera (ants, bees, and wasps), including insect sociality and sex allocation, predation and parental investment in solitary wasps of the genus Philanthus, and the structure of bee communities.


Seger has held research positions at Princeton University (1983-86), the University of Michigan (1982-83) and the University of Sussex, Brighton, England (1981-82).  Since 1986, he has been a professor in the Department of Biology at the University of Utah.  His numerous articles have appeared in such publications as Genetics, Nature, and the Journal of Evolutionary Biology; and he serves on the editorial boards of Behavioral Ecology, the American Naturalist, and Evolution.

Seger received a B.A. (1969) from the University of California, Santa Barbara, and an Ed.M. (1972) and Ph.D. (1980) from Harvard University.
