| Title | Advances In The Study Of Behavior, 34 | Type | Journal Article | ||
| Year | 2004 | Publication |
Abbreviated Journal | ||
| Volume | 34 | Issue | Pages | ||
| Keywords | |||||
| Abstract | DescriptionThe aim of Advances in the Study of Behavior remains as it has been since the series began: to serve the increasing number of scientists who are engaged in the study of animal behavior by presenting their theoretical ideas and research to their colleagues and to those in neighboring fields. We hope that the series will continue its “contribution to the development of the field”, as its intended role was phrased in the Preface to the first volume in 1965. Since that time, traditional areas of animal behavior have achieved new vigor by the links they have formed with related fields and by the closer relationship that now exists between those studying animal and human subjects. Advances in the Study of Behavior, Volume 31 continues to serve scientists across a wide spectrum of disciplines. Focusing on new theories and research developments with respect to behavioral ecology, evolutionary biology, and comparative psychology, these volumes foster cooperation and communications in these dense fields.AudienceExperimental psychologists studying animal behavior, comparative psychologists, ethologists, evolutionary biologists, and ichthyologists.ContentsContributors.

| Title | Hair Whorl Position as a Predictor of Learning Ability and Locomotor Behavior in Cattle? | Type | Journal Article | ||

| Abstract | The aim of our work was to investigate the hypothesis that the speed of solving the maze tests and locomotor behavior of heifers in open-field tests are affected by the height location of facial whorl. Fifty-eight Holstein heifers were used. Maze learning was observed at the age of 15 weeks, and an open-field test was applied at two ages, 16 weeks and 18 months. Whorl placement was recorded by one person as each heifer entered the scale. The hair whorl position was determined on the basis of two patterns: A) hair whorl high, middle and low and B) hair whorl high and low. Heifers with a high hair whorl were the fastest (77.8 ± 84.3 s) and heifers with a middle hair whorl the slowest (87.3 ± 100.3 s) in the A pattern during the maze tests. In the B whorl pattern, heifers with a high hair whorl ran across the maze in 84.5 ± 95.2 s and heifers with a low hair whorl in 84.1 ± 97.9 s. The number of crossed squares in a 5-minute open-field test in the A pattern was the non-significantly highest in heifers with a high hair whorl (43.4) at the age of 16 weeks. In the B whorl pattern, heifers with a high hair whorl were also more mobile, but neither differences in individual minutes nor in the whole 5 minutes were significant. Heifers with a high hair whorl displayed the strongest locomotory behavior (37.6 squares) and heifers with a low hair whorl (30.8) were the slowest in the A pattern at the age of 18 months. The differences were not significant. In the B whorl pattern, heifers with a high hair whorl crossed more squares, but the difference was not significant in comparison with heifers with a low hair whorl. We found that the time of traversing the maze and the locomotor activity in open-field test may not be influenced in the dairy cattle by the height facial whorl position |

| Title | Reconciliation and consolation in captive bonobos (Pan paniscus) | Type | Journal Article | ||

| Abstract | Although reconciliation in bonobos (Pan paniscus) has previously been described, it has not been analyzed heretofore by the postconflict (PC) match-control (MC) method. Furthermore, although reconciliation has been investigated before in this species, consolation has not. In this study we analyzed agonistic and affiliative contacts in all sex-class combinations to clarify and reevaluate the occurrence of reconciliation in bonobos via the PC-MC method. We also investigated the occurrence of consolation by analyzing the victims' triadic contact tendency (TCT), the influence of the sex of victims, and the relative occurrence of consolation and reconciliation. We collected 167 pairs of PC-MC observations in a captive group of bonobos (in Apeldoorn, The Netherlands). The conciliatory tendency (CCT) we obtained was tendentially lower than the mean value previously found for Yerkes captive chimpanzees. Close relationships, which were present in all female-female (FF) and some male-female (MF) dyads, positively affected reconciliation rates. When only adult PC-MC pairs (157) were considered, the mean TCTs and CCTs did not differ significantly. When we focused on types of PC affiliative contact, in the case of consolation we found a striking preference for sociosexual patterns. As to the relative occurrence of consolation and reconciliation, the highest level of the former was found in the absence of the latter. When reconciliation took place, consolation generally preceded it, suggesting that consolation may be a substitutive behavior. Our findings suggest that even if reconciliation remains the best option, consolation may be an alternative substitute for reconciliation that is used to buffer the tension originating from an unresolved conflict. Reconciliation and consolation are complex phenomena that are probably related to the life history of a group. Given that few studies have been conducted on this subject, we can not at this time make any generalizations regarding conflict resolution in certain species by comparing results among studies. | ||||

| Title | Variation in free jumping technique within and among horses with little experience in show jumping | Type | Journal Article | ||

| Abstract | OBJECTIVE: To quantify variation in the jumping technique within and among young horses with little jumping experience, establish relationships between kinetic and kinematic variables, and identify a limited set of variables characteristic for detecting differences in jumping performance among horses. ANIMALS: Fifteen 4-year-old Dutch Warmblood horses. PROCEDURE: The horses were raised under standardized conditions and trained in accordance with a fixed protocol for a short period. Subsequently, horses were analyzed kinematically during free jumping over a fence with a height of 1.05 m. RESULTS: Within-horse variation in all variables that quantified jumping technique was smaller than variation among horses. However, some horses had less variation than others. Height of the center of gravity (CG) at the apex of the jump ranged from 1.80 to 2.01 m among horses; this variation could be explained by the variation in vertical velocity of the CG at takeoff (r, 0.78). Horses that had higher vertical velocity at takeoff left the ground and landed again farther from the fence, had shorter push-off phases for the forelimbs and hind limbs, and generated greater vertical acceleration of the CG primarily during the hind limb push-off. However, all horses cleared the fence successfully, independent of jumping technique. CONCLUSIONS AND CLINICAL RELEVANCE: Each horse had its own jumping technique. Differences among techniques were characterized by variations in the vertical velocity of the CG at takeoff. It must be determined whether jumping performance later in life can be predicted from observing free jumps of young horses. | ||||

| Title | Effects of environmental stability and demonstrator age on social learning of food preferences by young Norway rats | Type | Journal Article | ||
| Year | 2004 | Publication |
Animal Behaviour | Abbreviated Journal | Anim. Behav. |
| Volume | 68 | Issue | 4 | Pages | 897-902 |
| Keywords | |||||
| Abstract | We used socially learned food preferences of Norway rats, Rattus norvegicus, to examine two common predictions of formal models of social learning in animals: (1) that animals living in relatively stable environments should be more attentive to socially acquired information than animals living in highly variable environments, and (2) that older demonstrators should have greater influence than younger demonstrators on the behaviour of young observers. Old and young demonstrators were equally effective in modifying the food preferences of juveniles that interacted with them. However, food choices of rats that were moved daily from one cage to another and fed at unpredictable times for unpredictable periods were less affected by demonstrators than were rats maintained in stable environments. Our results thus provided experimental support for the first, but not the second, prediction from theory. | ||||
