Research

Ann Fritz’s research is in behavioral ecology, particularly of insects. Ann’s lab is currently investigating reproductive biology, population dynamics and genetic introgression. Dr. Fritz’s research is currently melding behavior, morphology, and molecular methods to address hypotheses on the dynamics of sperm storage and use in female insects affecting paternity outcomes. Insects are ideal study subjects since there is often a temporal separation between insemination and fertilization allowing greater potential for female manipulation of sperm.  Female control over fertilization outcomes adds a new dimension to understanding the evolutionary conflict between the sexes, thus changing our views on the degree to which females influence male reproductive success.  Dr. Fritz also has collaborative projects on microbial constituents of the gut and reproductive tracts of flies, and with institutions in Brazil and Bolivia on the population biology/genetics of fruit flies of economic importance.
