Abstract | Calcium gluconate was administered to conscious horses at 3 different rates (0.1, 0.2, and 0.4 mg/kg/min for 15 minutes each). Serum calcium concentrations and parameters of cardiovascular function were evaluated. All 3 calcium administration rates caused marked increases in both ionized and total calcium concentrations, cardiac index, stroke index, and cardiac contractility (dP/dtmax). Mean arterial pressure and right atrial pressure were unchanged; heart rate decreased markedly during calcium administration. Ionized calcium concentration remained between 54% and 57% of total calcium concentration throughout the study. We conclude that calcium gluconate can safely be administered to conscious horses at 0.1 to 0.4 mg/kg/min and that administration will result in improved cardiac function. | ||||

Abstract | We studied the relationship of reciprocity, gender, and racial composition (Caucasian, African American, cross-race) of adolescent friendship dyads to similarity and proximity in 136 young adolescents. We found that adolescents selected friends who were of the same gender and race and that female dyads were more similar than male dyads on verbal achievement and several personality dimensions. Caucasian dyads were more similar than African American dyads on verbal achievement, mental alertness, and dominance. African American adolescents had more contact with their best friends outside school, whereas Caucasian adolescent friends had more in-school contact. African American students had fewer reciprocal relationships than the Caucasian students. Cross-race friendships were less reciprocal than same-race friendships. Race and gender were important in determining friendship patterns. Similarity and proximity were more important than reciprocity in understanding early adolescent friendships. | ||||

Abstract | ABSTRACT: e aim of this study was to test the effect of sire line on maze learning ability and locomotor behaviour in open-field tests of heifers, consistency over the time of grid crossing and relationship between the time of traversing the maze and grid crossings in open-field tests, respectively. We analysed the results of ethological tests for 54 Holstein heifers that descended from 7 sires. Maze behaviour was observed at the age of 15 weeks, an open-field test was applied at two age periods, 16 weeks and 18 months. We found out highly significant differences in the time of traversing the maze between heifers of different sire origin (P < 0.01). e number of grid crossings over the five minutes of the open-field test did not differ between the daughters of the age of 16 weeks and 18 months. Repeatability between the number of grid crossings at the age of 16 weeks and 18 months was proved by significant correlation (r = 0.2713*). On the contrary, significant relationships between the times of traversing the maze and locomotor behaviour in the open-field test (r =-0.3739*) were found only when the sequence of observations followed after a week pause (age of 15 and 16 weeks). |

Title | Dyadic relationships and operational performance of male and female owners and their male dogs | Type | Journal Article | ||
Year | 2009 | Publication | Behavioural Processes | Abbreviated Journal | Behav. Process. |
Volume | 81 | Issue | 3 | Pages | 383-391 |
Keywords | Dyadic interactions; Human-animal companions; Human-animal relationships; Human-dog dyads; Personality; Social stress | ||||
Abstract | In the paper we investigate how owner personality, attitude and gender influence dog behavior, dyadic practical functionality and the level of dog salivary cortisol. In three meetings, 12 female and 10 male owners of male dogs answered questionnaires including the Neo-FFI human personality inventory. Their dyadic behavior was video-taped in a number of test situations, and saliva samples were collected. Owners who scored highly in neuroticism (Neo-FFI dimension one) viewed their dogs as social supporters and spent much time with them. Their dogs had low baseline cortisol levels, but such dyads were less successful in the operational task. Owners who scored highly in extroversion (Neo-FFI dimension two) appreciated shared activities with their dogs which had relatively high baseline cortisol values. Dogs that had female owners were less sociable-active (dog personality axis 1) than dogs that had male owners. Therefore, it appears that owner gender and personality influences dyadic interaction style, dog behavior and dyadic practical functionality. | ||||

Abstract | The social development of a female rhesus monkey (Macaca mulatta) was followed from the day of birth until her death, at age 32 months. The subject, born to an older mother, had an extra autosome (karyotype: 43, XX, +18), an affliction that came about spontaneously. MRI scans revealed that she was also hydrocephalic. Compared to 23 female monkeys growing up under identical conditions, the subject showed serious motor deficiencies, a dramatic delay in the development of social behavior, poorly established dominance relationships, and greater than usual dependency on mother and kin. The subject was well-integrated into the social group, however. | ||||

Title | Patterns of coalition formation and spatial association in a social carnivore, the African wild dog (Lycaon pictus) | Type | Journal Article | ||
Year | 2003 | Publication | Journal of Zoology | Abbreviated Journal | J Zool |
Volume | 260 | Issue | 4 | Pages | 377-389 |
Keywords | coalitions; social systems; Carnivora; Lycaon pictus | ||||
Abstract | In many social species, relationships within groups seem to be non-random but related to variables such as rank, kinship or sexual attractiveness. The endangered African wild dog Lycaon pictus is a social carnivore that lives in large, stable packs, and intra-pack associations might be expected to display similar patterns. We investigated patterns of coalition formation (support during dominance interactions, and partnership interactions) and resting associations between members of a captive pack of 19 wild dogs. The social organization of the captive pack was similar to that of free-ranging packs in many respects. Polyadic (group) incidents of coalition support were also observed in a free-ranging pack. Patterns of coalition formation in the captive pack were related to rank. Most aggressive interactions involved high-ranking individuals (particularly the alpha, beta and third-ranking males) and coalitionary support tended to reinforce the existing hierarchy. However, there was at least one example of support influencing a successful rank challenge. Support was affected by potential risks and benefits, the latter including dominance through association and revolutionary alliances. An even stronger pattern overlaid associations between pack members: coalitions and resting associations were strongest between members of the same age–sex cohort, and may have enabled the eventual dominance of younger pack members over adults. Among adults, coalitionary associations were sometimes overridden by intersexual relationships. The results from this captive pack suggest that wild dogs are sensitive to differences in competitive ability. This information, in conjunction with strong affiliative bonds between littermates, is used to manoeuvre for position in the social hierarchy. It may also be important during dispersal, in encounters with other dispersing groups of the same sex. Although most features of the social structure of the captive pack were comparable to those of free-ranging packs, aspects such as the influence of relatedness on coalition formation still need to be explored. | ||||

Abstract | Heart rate, arterial blood pressures, respiratory rate, body temperature, and central nervous system excitement were compared before and after epidural administration of morphine (0.1 mg/kg), butorphanol (0.08 mg/kg), alfentanil (0.02 mg/kg), tramadol (1.0 mg/kg), the k-opioid agonist U50488H (0.08 mg/kg), or sterile water using an incomplete Latin square crossover design in five conscious adult horses. Treatments were administered into the first intercoccygeal epidural space. Significant (P <.05) reductions in respiratory rate were detected after epidural administration of morphine, alfentanil, U50488H, and sterile water. Additionally, significant (P <.05) head ptosis was observed within the first hour after administration of morphine, U50488H, and tramadol, but neither of these changes appeared to be of clinical significance. No treatment-related changes in motor activity or behavior were observed. | ||||

Abstract | Gegenstand und Ziel: Überprüfung der Tiergerechtheit von Abrufstationen für Kraftfutter und Heu in der Gruppenhaltung von Pferden anhand ethologischer und physiologischer Parameter im Vergleich zu konventionellen Fressständen. Material und Methoden: Die Verhaltensbeobachtungen fanden in 11 bzw. 10 Offenlaufställen mit Abrufstationen bzw. Fressständen statt. 270 Pferde wurden individuell unterschieden. Untersuchungsparameter waren: Drohverhalten mit und ohne Verletzungsrisiko, Meideverhalten, Verdrängung aus dem Fressstand sowie Herzfrequenz und Integumentverletzungen. In jedem Betrieb erfolgten kontinuierliche Direktbeobachtungen für je einen 24-Stunden-Tag (Tortenstückverfahren). Ergebnisse: Im Wartebereich der Abrufautomaten traten signifikant mehr Drohgesten ohne bzw. mit Verletzungsgefahr je Pferd und Tag (8,6 bzw. 3,0) auf als im Wartebereich der Fressstände (3,4 bzw. 0,9). Demgegenüber konnten die Pferde in Abrufstationen (1,4 Drohgesten je Pferd und Tag) ungestörter fressen als in Fressständen (3,2 Drohgesten je Pferd und Tag). Insgesamt betrachtet ergab sich jedoch bei beiden Fütterungssystemen eine geringe Anzahl an sozionegativen Interaktionen im Bereich der Futtereinrichtungen. Die Herzfrequenz lag im Warteareal im Durchschnitt im physiologischen Bereich (44,59 ± 11,73 Schläge/min). Integumentverletzungen im Zusammenhang mit dem Fütterungssystem traten nicht auf. Der wichtigste Einflussfaktor auf die Untersuchungskriterien war der Betrieb (Fläche, Konzeption, Management). Schlussfolgerung: Unter dem Aspekt der Tiergerechtheit hinsichtlich des Stress- und Verletzungsrisikos durch soziale Interaktionen eignen sich bei ordnungsgemäßer Gruppenhaltung mit fachgerechtem Management sowohl Fressstände als auch Abrufstationen für Pferde im Offenlaufstall. [Objective: A comparison with regard to animal welfare of feeding stalls and automatic feeding systems for hay and concentrates in group housing systems for horses using parameters of ethology and physiology. Material and method: The observations of animal behaviour took place in 10 stables with feeding stalls and in 11 stables with automatic feeding systems. The field around the feeding systems was divided into three areas with comparable dimensions (waiting area, exit area and inside of the feeding system). 270 horses were individually observed. Parameters of research comprised: threatening behaviour with and without risk of injury, avoiding behaviour, ”chasing away from the feeding place”, as well as heart rate and injuries of the integument. Every group of horses was continuously observed for 24 hours. This observation took place on four different days and comprised six sessions, each of 4 hours. Results: In the waiting area of the automatic systems there were significantly more threatening gestures with and without risk of injuries for each horse and day (8.6 and 3.0, respectively) than in the waiting area of the feeding stalls. In contrast, the horses could eat more relaxed in the automatic systems (1.4 threatening gestures for each horse and day) than in the feeding stalls (3.2 threatening gestures for each horse and day). All together the number of negative interactions in the feeding area of both feeding systems was relatively low. The heart rate was within the physiological range (44,59 ± 11,73 beats/min) in the waiting area. There were no injuries of the integument in correlation with the feeding systems. The most important factor of the observation criteria was the individual group housing system with its different dimension, conception and management. Conclusion: Under the aspect of animal welfare both feeding systems are suitable for horses with respect to the risk of stress and injuries by social interactions and under the condition of proper group housing with professional management.] |

Title | Illness as a source of variation of laterality in lions (Panthera leo) | Type | Journal Article | ||
Year | 2010 | Publication | Laterality | Abbreviated Journal | Laterality |
Volume | 16 | Issue | 3 | Pages | 356-366 |
Keywords | Brain lateralisation; Illness; Iions; Panthera leo; Footedness | ||||
Abstract | Brain asymmetry—i.e. the specialisation of each cerebral hemisphere for sensorimotor processing mechanisms and for specific cognitive functions—is widely distributed among vertebrates. Several factors, such as embryological manipulations, sex, age, and breeds, can influence the maintenance, strength, and direction of laterality within a certain vertebrate species. Brain lateralisation is a universal phenomenon characterising not only cerebral control of cognitive or emotion-related functions but also cerebral regulation of somatic processes, and its evolution is strongly influenced by social selection pressure. Diseases are well known to be a cost of sociality but their role in influencing behaviour has received very little attention. The present study investigates the influence of illness conditions as a source of variation on laterality in a social keystone vertebrate predator model, the lion. In a preliminary stage, the clinical conditions of 24 adult lions were assessed. The same animals were scored for forelimb preference when in the quadrupedal standing position. Lions show a marked forelimb preference with a population bias towards the use of the right forelimb. Illness conditions strongly influenced the strength of laterality bias, with a significant difference between clinically healthy and sick lions. According to these results, health conditions should be recognised as an important source of variation in brain lateralisation. | ||||
