Scent marking in wild banded mongooses: 1. Sex-specific scents and overmarking
Overmarking occurs when one individual places its scent mark directly on top of the scent mark of another individual. Although it is almost ubiquitous among terrestrial mammals, we know little about the function of overmarking and detailed field observations are rare. We investigated the chemical composition of scents and patterns of overmarking by wild banded […]
Scent marking in wild banded mongooses: 2. Intrasexual overmarking and competition between males
Sexual selection has resulted in the elaboration of secondary sexual characteristics in many animals. Although mammalian scent glands, secretions and marking behaviour are commonly sexually dimorphic, these traits have received little attention compared to avian plumage and mammalian weaponry. Overmarking, when one individual places a scent mark directly over that of another individual, is of […]
Scent marking in wild banded mongooses: 3. Intrasexual overmarking in females
In contrast to numerous studies of scent marking in male mammals, studies of female scent marking are relatively rare. We have previously shown that communally breeding female banded mongooses, Mungos mungo, are more likely to overmark the scent of other females. Here we describe female overmarking patterns in more detail, and discuss these results in […]
Why do river otters scent-mark? An experimental test of several hypotheses
We tested several alternative hypotheses about the function of scent marking by the North American river otter, Lontra canadensis. Otters may mark at latrine sites with spraints (faeces) to (1) signal species identity, (2) advertise their reproductive status, (3) establish and maintain territories, and (4) communicate social status and identity to group members. Olfactory preference […]
