Bush and Smeller — Mitchell Bush and Johanna Smeller — collaborated on at least 17 studies.
In at least one, they collaborated with another Bush:
“Physiologic Measures of Nonhuman Primates During Physical Restraint and Chemical Immobilization,” Bush M, Custer R, Smeller J, Bush LM., Journal of the American Veterinary Medical Association, vol. 171, no. 9, November 1, 1977, pp. 866-9. (Thanks to investigator Ben Haller for alerting us to the collaboration). The authors report: “Two types of behavior were observed during the physical restraint of golden marmosets. Some of the marmosets were excited during restraint, with a great deal of struggling and vocalizing. The other marmosets were quiet and calm, with minimal struggling.”
