  Title Reconciliation in Wolves (Canis lupus) – New Evidence for a Comparative Perspective Type Journal Article
  Year 2008 Publication Ethology Abbreviated Journal Ethology  
  Volume 114 Issue Pages 298 - 308  
  Keywords  
  Abstract Social animals gain benefits from cooperative behaviours. However, social systems also imply competition and conflict of interest. To cope with dispersal forces, group-living animals use several peace-keeping tactics, which have been deeply investigated in primates. Other taxa, however, have been often neglected in this field research. Wolves (Canis lupus) with their high sociality and cooperative behaviour may be a good model species to investigate the reconciliation process. In this study, we provide the first evidence for the occurrence of reconciliation in a group of zoo-kept wolves. The conciliatory contacts were uniformly distributed across the different sex-class combinations. We found a linear dominance hierarchy in the colony under study, although the hierarchical relationships did not seem to affect the reconciliation dynamics. Moreover, both aggressors and victims initiated first post-conflict affinitive contact with comparable rates and both high- and low-intensity conflicts were reconciled with similar percentages. Finally, we found that coalitionary support may be a good predictor for high level of conciliatory contacts in this species.

  Title Temporal Limitations on Social Learning of Novel Predators by Indian Mynahs, Acridotheres tristis Type Journal Article
  Year 2009 Publication Ethology Abbreviated Journal Ethology  
  Volume 115 Issue 3 Pages 287-295  
  Keywords  
  Abstract Antipredator vocalizations of social companions are important for facilitating long-term changes in the responses of prey to novel predator stimuli. However, dynamic variation in the time course of acoustic communication has important implications for learning of predator cues associated with auditory signals. While animals often experience acoustic signals simultaneously with predator cues, they may also at times experience signals and predator stimuli in succession. The ability to learn about stimuli that are perceived not only together, but also after, acoustic signals has the potential to expand the range of opportunities for learning about novel events. Earlier work in Indian mynahs (Acridotheres tristis) has revealed that subjects acquire a visual exploratory response to a novel avian mount after they have experienced it together with conspecific distress vocalizations, a call produced in response to seizure by a predator. The present study explored to what extent such learning occurred if the avian mount was experienced after, rather than simultaneously with, distress calls, such as might happen if call production is interrupted by prey death. Results showed that mynahs that experienced a novel avian mount simultaneously with the sound of distress calls exhibited a sustained exploratory response to the mount after training relative to before that was not apparent in birds that received distress calls and mount in succession. This finding suggests that vocal antipredator signals may only trigger learning of environmental stimuli with which they share some temporal overlap. Recipients may need to access complementary non-vocal cues from the prey victim to learn about predator stimuli that are perceived after vocal behaviour.

  Title Boldness and Information Use in Three-Spined Sticklebacks Type Journal Article
  Year 2010 Publication Ethology Abbreviated Journal Ethology  
  Volume 116 Issue 5 Pages 440-447  
  Keywords  
  Abstract Abstract In foraging groups, individuals may utilise information from their social environment to aid decision making when choosing where to search for food. Little work has looked at the costs or benefits of behavioural differences, such as consistent individual variation in boldness, with respect to learning ability. Here, we investigate the response of three-spined stickleback (Gasterosteus aculeatus) to ‘social cues’, ‘local enhancement’ and ‘public information’ during foraging tasks. Our results confirm previous work suggesting that this species responds to social cues and local enhancement but not public information. Variation in boldness did not affect the use of different types of information. However, time taken to make a choice and reach a patch varied between fish with different levels of boldness. Contrary to expectation, shy fish were the more variable individuals, having a greater range of reaction times when responding to the tasks. This suggests that individual behavioural differences still play a role when utilising information obtained from the environment and may influence the relative benefits that could result in different contexts.

  Title Dominance relationships and patterns of aggression in a bachelor group of Sorraia horses (Equus caballus) Type Journal Article
  Year 2010 Publication Journal of Ethology Abbreviated Journal J. Ethol.  
  Volume 28 Issue 1 Pages 35-44  
  Keywords Horse – Equus – Dominance relationship – Rank – Agonistic interaction  
  Abstract Abstract  The influence of individual factors on dominance rank and the relationship between rank distance and patterns of aggression predicted by models of evolutionarily stable strategies (ESS) of animal conflict were investigated in a managed bachelor group of Sorraia horses, Equus caballus. The group was composed of four to six stallions 3- to 12-years-old during the study period. The dominance hierarchy was significantly linear and rank was not related to age, weight, height or aggressiveness. Frequency and intensity of agonistic interactions were low, but higher-ranking stallions did not receive lower aggressiveness than lower-ranking stallions. There was some evidence that dominance relationships were more contested among close-ranking stallions, as predicted. Agonistic-related interactions among close-ranking stallions served similar functions to those among distant-ranking stallions, but the latter interacted more frequently than expected for access to resting sites and/or resting partners. Therefore, we found some evidence that agonistic-related interactions among distant-ranking stallions play a larger role in providing access to valuable and defendable resources than those among close-ranking stallions. Nevertheless, the fact that space to escape from aggression was limited and breeding access was independent from dominance rank may have reduced the benefits relative to costs of aggression and therefore limited the occurrence of contests over dominance and resources.

  Title Affiliative relationships among Sorraia mares: influence of age, dominance, kinship and reproductive state Type Journal Article
  Year 2010 Publication Journal of Ethology Abbreviated Journal J. Ethol.  
  Volume 28 Issue 1 Pages 133-140  
  Keywords Sorraia horse – Affiliative relationship – Dominance – Kinship – Reproductive state  
  Abstract Abstract  Affiliative relationships among mares were examined in a managed group of Sorraia horses, Equus caballus, over a 3-year period. We assessed the influence of age, dominance, kinship and reproductive state on the strength of affiliative relationships and diversity of partners. The herd comprised 9–11 mares that had known each other since birth, their foals and a stallion that remained in the group exclusively during the breeding season. In contrast to a previous study, kinship did not significantly affect bonds. Mares tended to spend more time in proximity to those in the same reproductive state. Affiliative relationships among mares were relatively stable but their strength decreased after foaling, possibly as a function of foal protection and bonding between dam and foal. There was no consistent evidence that mares disengaged from affiliative relationships with increasing age. As expected, dominant mares and barren mares contributed the most to affiliative relationships. Dominance rank increased with age, but dominance relationships were stable and did not change after foaling. Overall, reproductive state was the factor that had the most consistent influence on affiliative relationships among Sorraia mares.

  Title Understanding Social Behaviour with the Help of Complexity Science (Invited Article) Type Journal Article
  Year 2002 Publication Ethology Abbreviated Journal Ethology  
  Volume 108 Issue 8 Pages 655-671  
  Keywords  
  Abstract Abstract In the study of complexity, a new kind of explanation has been developed for social behaviour. It shows how patterns of social behaviour can arise as a side-effect of the interaction of individuals with their social or physical environment (e.g. by self-organization). This development may influence our ideas about the direct causation and evolution of social behaviour. Furthermore, it may influence our theories about the integration of different traits. This new method has been made possible by the increase in computing power. It is now applied in many areas of science, such as physics, chemistry, sociology and economics. However, in zoology and anthropology it is still rare. The major aim of this paper is to make this method more generally accepted among behavioural scientists.

  Title Self-Organized Shape and Frontal Density of Fish Schools Type Journal Article
  Year 2008 Publication Ethology Abbreviated Journal Ethology  
  Volume 114 Issue 3 Pages 245-254  
  Keywords  
  Abstract Abstract Models of swarming (based on avoidance, alignment and attraction) produce patterns of behaviour also seen in schools of fish. However, the significance of such similarities has been questioned, because some model assumptions are unrealistic [e.g. speed in most models is constant with random error, the perception is global and the size of the schools that have been studied is small (up to 128 individuals)]. This criticism also applies to our former model, in which we demonstrated the emergence of two patterns of spatial organization, i.e. oblong school form and high frontal density, which are supposed to function as protection against predators. In our new model we respond to this criticism by making the following improvements: individuals have a preferred ‘cruise speed’ from which they can deviate in order to avoid others or to catch up with them. Their range of perception is inversely related to density, with which we take into account that high density limits the perception of others that are further away. Swarm sizes range from 10 to 2000 individuals. The model is three-dimensional. Further, we show that the two spatial patterns (oblong shape and high frontal density) emerge by self-organization as a side-effect of coordination at two speeds (of two or four body lengths per second) for schools of sizes above 20. Our analysis of the model leads to the development of a new set of hypotheses. If empirical data confirm these hypotheses, then in a school of real fish these patterns may arise as a side-effect of their coordination in the same way as in the model.

  Title Review of some research areas of applied and theoretical interest in domestic animal behavior Type Journal Article
  Year 1980 Publication Applied Animal Ethology Abbreviated Journal Appl. Animal. Ethol.  
  Volume 6 Issue 2 Pages 111-119  
  Keywords  
  Abstract There are numerous areas worthy of study in the field of domestic animal behavior or applied ethology. In this paper a few areas are offerred as particularly worthy of attention. These areas are worthwhile either because they have received little or no study and are of basic interest or because they have application to current problems of livestock production. The study of cat behavior falls in the former category. Neither the food and water sources, the reproductive success rate nor even the social interactions of cats in the large populations found in both rural and urban environments are known. Pigs as a species have already been the subjects of many behavior studies; nevertheless, there are still gaps in our knowledge of the underlying principles of swine behavior. The physiological basis of maternal behavior, for example, has not been studied in swine or in any domestic species. The sensory basis of udder location by the neonatal piglet deserves study also. Some aspects of olfactory and vocal communication of pigs have been studied, but only one of what may be a large number of pheromones of pigs has been chemically identified. The message conveyed by the vocal interactions between adult swine of the same sex is unknown, as is the role of facial and postural expressions in porcine communication. The two major problems of pig behavior under conditions of intensive livestock management are tail biting and reproductive failure. The application of behavioral techniques to these problems might help to attenuate those problems as well as broaden our understanding of normal pig behavior. Horse behavior has also been a relatively neglected field of study. Of particular interest is the significance of the flehmen gesture used by both mares and stallions in a variety of situations. Flehmen may be related to the function of the vomeronasal organ, but both observational and physiological studies should be performed to verify the hypothesis.
