摘要: The function of scent marking varies not only between species, but also among different age/sex classes within the same species. We conducted a longitudinal study 26 free-living spotted hyenas to describe ontogeny anal gland (‘pasting’) in this Males increased proportional abundance overmarking cub and subadult periods, while female pasting remained consistent throughout early development. Pasting was sexually dimorphic that male cubs pasted more frequently than cubs, subadults countermarked often their peers. By examining pouches 113 anaesthetized individuals, we determined do consistently produce paste until third year. In light these findings, potential functions by juvenile were discussed.
