I am not expert enough to argue with the author, but I have read research contrary to this. The research I have read states that the majority of the chasing, fighting, and marking is done by the 2.5-3.5 year old crowd. The older bucks sit back and wait for the does to come in and then chase off the younger bucks and lock down with the does. The study indicated that in bucks of breeding age (1.5-6.5 for this study) bucks in the 3.5 year old age group bred the most does, but the discrepency was not very large. I believe the breeding age deer that bred that least number of does and bred only bred 1, but the deer breeding the most bred 9. The average was 4 does per buck. So dominance does not mean that bucks are breeding vastly larger numbers of does. Maybe more than the younger bucks, but certainly not a harem.
