It is generally accepted that comparative studies on animal communication can provide insights into the coevolution of social life, vocal communication, cognitive capacities and notably the emergence of some human language features. Recent studies suggested that non-human primates possess combinatorial abilities that may allow a diversification of vocal repertoires or a richer communication in spite of limited articulatory capacities. However, the functions of combined calls and the information that receivers can extract remain poorly understood. This thesis investigated call combination systems in two species of guenons: Campbell's monkey (Cercopithecus Campbelli) and Diana monkey (Cercopithecus Diana). Firstly, I studied the combinatorial structure and relevance to receivers of combined calls in of both species using playback experiments. Results confirmed the presence of a suffixation mechanism reducing the emergency of danger signaled by calls of male Campbell's monkeys. Also, they showed that combined calls of females Diana monkeys convey linearly information via their two units, which signal respectively caller's emotional state and identity. Secondly, focusing on the context associated with the emission of simple and combined female Campbell's monkey calls, results revealed flexible use of combination reflecting the immediate need to remain cryptic (i.e. simple calls) or to signal caller's identity (i.e. combined calls). Finally, I compared females' communication systems of both species to identify their similarities and differences. As predicted by their close phylogenetic relatedness, their repertoires are mostly based on homologous structures. However, the females differ strongly in their use of those structures. In particular, the great number of calls combined by Diana monkeys increases considerably their vocal repertoire compared to Campbell's monkeys. Given that the combinations are non-random, meaningful to receivers and used flexibly with the context, I propose a parallel with a rudimentary form of semantic morphosyntax and discuss more generally the possible existence of similar capacities in other non-human animals.

This thesis is about olfactory communication in mink (<i>Mustela vison</i>) and how it may relate to their social behaviour. The sources of mammalian social odours and studies of scent marking by carnivores were discussed. The possible functions of scent marking in territories were also discussed, with particular reference to Gosling's scent matching hypothesis. The distribution of faeces (scats) in a coastal population of mink was ddtermined on a monthly basis. Most scats were found in the months December to April, which includes the mating season. Although scats tended to occur singly, they had a clumped distribution because single scats tended to be deposited around certain features in the enviornment. Scats were found around the same features over a number of months. The areas where scats were deposited also tended to have a clumped distribution when data from all months were considered. A trained male mink was able to discriminate between the faeces of mink irrespective of their sex or degree of association with the experimental animal. Over a 48 hour period, male mink over-marked faecal samples from other mink with their own faeces. Females normally only over-marked faeces from females kept in neighbouring cages. During lactation and in August and September the females over-marked faeces from unknown males and females. When testing the immediate response of mink to faeces, both male and female mink spent more time sniffing at faeces from other mink than at their own faeces. Males also spent more time sniffing at faeces from females during the reproductive period than they did outside the reproductive period. During their immediate response to faeces, the males tended to produce trails of urine on top of or beside samples of faeces from unknown males and females. While in reproductive condition, mink spent more time sniffing and produced more urine trails in response to samples of urine collected from females that were likely to be in oestrus than at samples collected from females unlikely to be in oestrus. Outside the reproductive period both males and females produced urine trails in response to urine from unknown males and females. Male mink produced more scent marks in response to samples of old (24 hours) anal sac secretion than to fresh anal sac secretion. Female mink produced few scent marks in response to either sample. Anal sac secretion when sprayed from a model mink, caused both mink and potential predators of mink, to back away from the model. The presence of the major constituent of the anal sac secretion, 2,2-dimethylthietane was shown to reduce the 'trapability' of mink and small rodents, and to cause feeding suppression in rabbits over a 24 hour period. Experiments designed to test predictions of Goslings hypothesis could not support or refute the hypothesis.
