Social Structuring

Individual movement influences the spatial and social structuring of a population. Animals regularly use the same paths to move efficiently to familiar places, or to patrol and mark home ranges. We found that Australian sleepy lizards (Tiliqua rugosa), a monogamous species with stable pair-bonds, repeatedly used the same paths within their home ranges and investigated whether path re-use functions as a scent-marking behaviour, or whether it is influenced by site familiarity. Lizards can leave scent trails on the substrate when moving through the environment and have a well-developed vomeronasal system to detect and respond to those scents. Path re-use would allow sleepy lizards to concentrate scent marks along these well-used trails, advertising their presence. Hypotheses of mate attraction and mating competition predict that sleepy lizard males, which experience greater intra-sexual competition, mark more strongly. Consistent with those hypotheses, males re-used their paths more than females, and lizards that showed pairing behaviour with individuals of the opposite sex re-used paths more than unpaired lizards, particularly among females. Hinterland marking is most economic when home ranges are large and mobility is low, as is the case in the sleepy lizard. Consistent with this strategy, re-used paths were predominantly located in the inner 50% home range areas. Together, our detailed movement analyses suggest that path re-use is a scent marking behaviour in the sleepy lizard. We also investigated but found less support for alternative explanations of path re-use behaviour, such as site familiarity and spatial knowledge. Lizards established the same number of paths, and used them as often, whether they had occupied their home ranges for one or for more years. We discuss our findings in relation to maintenance of the monogamous mating system of this species, and the spatial and social structuring of the population.

Alpine Marmot

The aim of this fieldwork was to provide information about the function of scent-marking behaviour in the alpine marmot (Marmota marmota). Twenty-three identified animals were observed on their home range during the season of activity, from May to September, during which the probability and rate of cheek rubbing decreased significantly. Cheek rubbing was performed more by resident adults than by 2-year-olds or yearlings. The resident adult pairs made "marking tours" during which numerous successive bouts of scent marking occurred throughout most of the home range. Scent marks were not evenly distributed within home ranges. Principal and, if present, accessory burrow systems were saturated with scent deposits, the boundaries being marked significantly more than the central area. We tested the reactions of marmots to strange odours by presenting them with two glass tubes, one clean (control) and the other covered with marks deposited by marmots belonging to other groups. The results showed that residents tended to mark the experimental tubes more frequently, or at least more intensively, than the control ones. In the alpine marmot, cheek rubbing appears to be a multipurpose activity. It is used to advertise the occupancy of burrows and, as predicted by Gosling, scent marks were also laid down where the risk of intrusion was greatest, i.e., at the boundaries, so that intruders could detect them more readily. The results of field tests support another of Gosling's predictions, that residents will tend to overmark any mark deposited by a strange animal inside their territory. Thus, in the alpine marmot, cheek rubbing can play a role in territorial defence.

The Common

Aspects of the behaviour and ecology of Vombatus ursinus were studied in largely cleared agricultural land in a coastal area in northeast Tasmania. The average density of V. ursinus was 20 individuals.km-2 over the whole study area but around 60.km-2 in an intensively studied section. Burrows were concentrated in areas of sandy soil where a dense cover of native vegetation had been maintained. Only short, shallow burrows were present in areas of dolerite, probably because of the difficulty of digging. Home-ranges of different individuals overlapped. Wombats were not active continually through the night and varied in time of emergence from their burrow and the time spent above ground. Often more than one burrow was used on the same night, with more than one individual making use of a burrow, but usually not at the same time. Disputes over the use of burrows occurred. Individuals frequently sniffed around burrows and investigated for the presence of occupants. Males may use this as a strategy for finding females in oestrus. Mating behaviour was observed once. Wombats are solitary and actively avoid the presence of others. Odour in faecal pellets and from scent marking probably plays an important social role by providing information on the individuals sharing a home-range and the occurrence of strangers. Dominant animals may be intolerant of the presence of certain individuals within their home-range.

Context Conserving large carnivores can be challenging because of conflicts with human land use and competition with humans for resources. Predation on domestic stock can have negative economic impacts particularly for owners of small herds, and tools for minimising carnivore depredation of livestock are needed. Canids use scent marking to establish territories and avoid intraspecific conflict. Exploiting scent-marking behaviour may provide a means for manipulating canid movements. Aims We hypothesised that human-deployed scent marks (i.e. ‘biofence’) could be used to manipulate the movements of grey wolves (Canis lupus) in Idaho, USA. Methods We deployed 65 km of biofence within three wolf-pack territories during summer 2010 and 2011 and used location data from satellite-collared wolves and sign surveys to assess the effectiveness of biofencing. Key results Location data provided by satellite-collared wolves and sign surveys in 2010 showed little to no trespass of the biofence, even though the excluded areas were used by the packs in previous summers. We also opportunistically deployed a biofence in between a rendezvous site of a resident pack and a nearby sheep grazing allotment; the pack was not implicated in any depredations in summer 2010, even though they had killed sheep every year since 2006. Location data provided by satellite-collared wolves in summer 2011 showed that wolves did trespass biofences. Conclusions Biofencing effectively manipulated the movements of wolves in the first year of our study, but not the second. Implications Our work suggests that biofencing may be most limited by the apparent necessity to maintain a continuous presence once the biofence is established. The inherent labour and costs associated with such efforts may limit the usefulness of biofencing. Our work can be improved on through further testing that maintains biofencing over a longer timeframe (>3 months), samples several animals per treatment pack, and uses a treatment and control design.

Strip Transect

Both the male and the female klipspringer scent-mark their ranges. A pair of pre-orbital glands below the eyes produces the scent. The secretion is a sticky, substance that is deposited on a suitable twig. Klipspringer scent marks were surveyed in a specific klipspringer range in the Kruger National Park with the use of a strip transect method. The results showed that klipspringer in the Kruger National Park scent-mark more frequently on the boundaries of their ranges and also more on those sides where there is another resident klipspringer group.

ABSTRACT Male hamsters were tested for their interest in females on different days of the oestrous cycle. Behaviour of males towards novel females was measured and (after exposure to vaginal secretion) towards females that matched or did not match that vaginal odour. Because pro-oestrous (day 4) females lay trails of vaginal secretion and will become receptive within a few hours, it was predicted that males would show more interest in day 4 than in other dioestrous females. While males showed no preference for novel, pro-oestrous females over dioestrous females, after pre-exposure to odour, their response to females was determined by the cycle day of the vaginal secretion to which they had been exposed. Males pre-exposed to vaginal odour from females carrying large implants of oestrogen preferred to spend more time with females who matched that vaginal odour than mismatching females and to sniff them more. This preference was not seen if the females carried small oestrogen implants or had no replacement oestrogen. This suggests that pro-oestrous females (who are known to have high circulating levels of oestrogen) can, by means of their scent-marking behaviour, attract and keep males nearby until they become receptive.

Marking Behaviour

AbstractMost terrestrial mammals deposit scent marks to communicate with conspecifics. We examined the scent marking behaviour of meadow voles and prairie voles, species with different mating systems and social organizations, to determine whether voles scent mark according to the 'targeting' response, the 'avoidance' response, or the 'shotgun' response. The targeting response occurs when the second scent donor deposits more of its scent marks in an area marked by the first scent donor than in an unscented area. The avoidance response occurs when the second scent donor deposits more of its scent marks in an unscented area than in an area marked by the first scent donor. The shotgun response occurs when the second scent donor deposits a similar number of its scent marks in an area containing scent marks of a conspecific and in an area containing no conspecific scent marks. We allowed voles simultaneous access to an arena containing two arms: one of the arms was scented by a conspecific and the other arm was unscented. We recorded the number of marks deposited by the voles in each arm and the amount of time they spent investigating marks deposited previously in the scented arm. Our data provide no support for the avoidance response, but provide support for the shotgun response and the target response. Species and sex differences in the scent marking behaviours of voles when they encounter the scent marks of conspecifics are discussed within the framework that scent marking responses depend on the voles' social organization and mating system, and that these responses may reflect the tactics males and females use to attract mates and compete with same-sex conspecifics.
