“Later, studies that I conducted as a graduate student in Maryland identified competition among yearling males as a likely cause of dispersal. The present study demonstrated the likely involvement of both mechanisms in dispersal of white-tailed deer.”
So,after doing 3 studies they still don't know which is the major factor for buck dispersal and it is only "likely" that both mechanisms of dispersal are involved. Furthermore , the spread of disease among deer is not a major concern at this time, so the study did nothing to improve the current deer management in the state and did not benefit hunters in any way.
