Timing of Mating, Sperm Dynamics: DISCUSSION(7)

DISCUSSION(7)

This supports radio-tracking data collected by Lazenby-Cohen and Cockburn from a female on Day 18 after the commencement of the rut; these data indicated that this female was not visiting male nest trees at this time and had significantly reduced her foraging range from that observed early (Day 7) in the mating period. Together, these data strongly suggest that the 3 females radio-tracked by Lazenby-Cohen and Cockburn early and late in the rut were not receptive at the times they were being followed and that the 2 females followed on Day 18 of the rut had probably already mated and ovulated. buy flovent inhaler

The trapping data presented in this study suggested that male activity was low during the first week of the rut. This supports Lazenby-Cohen and Cockburn’s trapping and radio-tracking data collected during this period showing a decline in male ranges in the first week of the mating season. These authors suggest that the smaller male ranges observed at this time resulted from a restriction of male activity to only a few nest trees during this period, with most foraging occurring at the base of these communal nests. Male capture rates in our study were significantly higher on Days 8 and 9 after the commencement of mating (13 and 14 August) than at any other time examined throughout the rut.
