	Title	Interactive video playback and opponent assessment in lizards			Type	Journal Article
	Year	2002	Publication	Behavioural Processes	Abbreviated Journal	Behav. Process.
	Volume	59	Issue	2	Pages	55-65
	Keywords	Animal communication; Display; Lizard; Playback; Visual signal
	Abstract	Video playback has been used to explore many issues in animal communication, but the scope of this work has been constrained by the lack of stimulus-subject interaction. In many natural contexts, each participant's signalling behaviour is dependent from moment-to-moment on that of the other. Analyses of acoustic communication demonstrate the value of reproducing such social contingencies. We assessed the utility of interactive playback for studies of visual signalling by comparing the responses of male Jacky dragons, Amphibolurus muricatus, to interactive and non-interactive digital video playbacks of a life-sized conspecific. Displays produced by lizards in the interactive condition had the effect of suppressing the aggressive display of their simulated opponent. Each stimulus sequence generated during an interactive playback was subsequently played to a size-matched control animal. Males that could interact with the video stimulus responded principally with aggressive displays, while those that could not produced a mixture of aggressive and appeasement signals. Adding a degree of receiver responsiveness is hence sufficient to alter the type of signal evoked, even when video stimuli are physically identical. Interactive playback permits the experimental study of a broader range of theoretical topics and can enhance the realism of video stimuli.

	Title	Heart rate and heart rate variability during a novel object test and a handling test in young horses			Type	Journal Article
	Year	2002	Publication	Physiology & Behavior	Abbreviated Journal	Physiol. Behav.
	Volume	76	Issue	2	Pages	289-296
	Keywords	Heart rate; Heart rate variability; Consistency; Behavioral tests; Temperament; Emotionality; Horses
	Abstract	Forty-one Dutch Warmblood immature horses were used in a study to quantify temperamental traits on the basis of heart rate (HR) and heart rate variability (HRV) measures. Half of the horses received additional training from the age of 5 months onwards; the other half did not. Horses were tested at 9, 10, 21 and 22 months of age in a novel object and a handling test. During the tests, mean HR and two heart variability indices, e.g. standard deviation of beat-to-beat intervals (SDRR) and root mean square of successive beat-to-beat differences (rMSSD), were calculated and expressed as response values to baseline measures. In both tests, horses showed at all ages a significant increase in mean HR and decrease in HRV measures, which suggests a marked shift of the balance of the autonomic nervous system towards a sympathetic dominance. In the novel object test, this shift was more pronounced in horses that had not been trained. Furthermore, statistical analysis showed that the increase in mean HR could not be entirely explained by the physical activity. The additional increase in HR, the nonmotor HR, was more pronounced in the untrained horses compared to the trained. Hence, it is suggested that this nonmotor HR might be due to the level of emotionality. HR variables showed consistency between years, as well as within the second year. These tests bring about a HR response in horses, part of which may indicate a higher level of emotionality; and horses show individual consistency of these HR variables over ages. Therefore, it is concluded that mean HR and HRV measures used with these tests quantify certain aspects of a horse's temperament.

	Abstract	HÜBENER, EBERHARD, Schmeichelnder Sitz, atmender Schenkel, flüsternder Zügel Vom feinfühligen, partnerschaftlichen Umgang mit dem Pferd und über Nöte der bundesdeutschen Reiterei. Mit einem Geleitwort von Dr. Reiner Klimke 2. ergänzte Aufl. Hildesheim 2002. 223 S. mit 63 Abb., davon 3 farbig. Gebunden. Reihe: (NOVA HIPPOLOGICA.) ISBN: 3-487-08408-2 Dieses Buch beantwortet eine Reihe zentraler Fragen zur Reitlehre und zum Umgang mit dem Pferd gründlich und leicht verständlich. Es ist daher hilfreich für alle, die sich am und auf dem Pferd gern helfen lassen. Ob sie nun nur zum Vergnügen oder mit turniersportlichen Ambitionen reiten. Ob sie lernen oder lehren. Der vorliegenden zweiten Auflage ist eine neue Arbeit des Autors beigebunden: Nachdem eine Video-Analyse seinen “selbsttätigen Schenkel” bestätigt hat, wird jetzt endlich auch das “Sitz-Rätsel” definitiv gelöst. Die Video-Technik hat ermöglicht, das Zusammenspiel von Gangart, Bewegungen von Pferderumpf und -rücken, Sitz des Reiters und Hilfengebung zum Nutzen des Reiter-Rückgrats, der keineswegs beliebig belastbaren Wirbelsäule des Pferdes und kultivierten, feinfühligen Reitens zu entschlüsseln. Reitunterricht kann anders aussehen. Irrwege sind vermeidbar geworden.

	Title	*Dogs' (Canis familiaris) responsiveness to human pointing gestures*			Type	Journal Article
	Year	2002	Publication	Journal of Comparative Psychology (Washington, D.C. : 1983)	Abbreviated Journal	J Comp Psychol
	Volume	116	Issue	1	Pages	27-34
	Keywords	Analysis of Variance; Animals; Behavior, Animal; Choice Behavior; Dogs/psychology; Female; Gestures; Male; *Recognition (Psychology); Species Specificity
	Abstract	In a series of 3 experiments, dogs (Canis familiaris) were presented with variations of the human pointing gesture: gestures with reversed direction of movement, cross-pointing, and different arm extensions. Dogs performed at above chance level if they could see the hand (and index finger) protruding from the human body contour. If these minimum requirements were not accessible, dogs still could rely on the body position of the signaler. The direction of movement of the pointing arm did not influence the performance. In summary, these observations suggest that dogs are able to rely on relatively novel gestural forms of the human communicative pointing gesture and that they are able to comprehend to some extent the referential nature of human pointing.

	Title	Conditioning taste aversions to locoweed (Oxytropis sericea) in horses			Type	Journal Article
	Year	2002	Publication	Journal of Animal Science	Abbreviated Journal	J. Anim. Sci.
	Volume	80	Issue	1	Pages	79-83
	Keywords
	Abstract	Locoweed (Oxytropis sericea) is a serious poisoning problem for horses grazing on infested rangelands in the western United States. Our objectives were to determine 1) whether lithium chloride or apomorphine would condition aversions to palatable foods, and at what doses, and 2) whether horses could be averted to fresh locoweed in a pen and grazing situation. Apomorphine was not an acceptable aversive agent because at the dose required to condition an aversion (> or = 0.17 mg/kg BW), apomorphine induced unacceptable behavioral effects. Lithium chloride given via stomach tube at 190 mg/kg BW conditioned strong and persistent aversions to palatable feeds with minor signs of distress. Pen and grazing tests were conducted in Colorado to determine if horses could be averted to fresh locoweed. Pen tests indicated that most horses (5/6) were completely averted from locoweed. Treated horses ate 34 g of fresh locoweed compared to 135 g for controls (P < 0.01) during three pen tests when offered 150 g per test. One horse (T) in the treatment group ate locoweed each time it was offered in the pen, but ate no locoweed while grazing. In the grazing trial, control horses averaged 8.6% of bites of locoweed (P < 0.01) during the grazing portion of the study, whereas treated horses averaged <0.5%. One treated horse (S) accounted for all consumption; he consumed 15% of his bites as locoweed in a grazing bout on d 2 of the field study. Thereafter, he was dosed a second time with lithium chloride and ate no locoweed in the subsequent 5 d. Three of six horses required two pairings of lithium chloride with fresh locoweed to condition a complete aversion. The results of this study indicate that horses can be averted from locoweed using lithium chloride as an aversive agent, and this may provide a management tool to reduce the risk of intoxication for horses grazing locoweed-infested rangeland.

	Title	Leadership behavior in relation to dominance and reproductive status in gray wolves, Canis lupus			Type	Journal Article
	Year	2002	Publication	Canadian Journal of Zoology	Abbreviated Journal
	Volume	80	Issue		Pages	1405-1412
	Keywords
	Abstract	We analyzed the leadership behavior of breeding and nonbreeding gray wolves (Canis lupus) in three packs during winter in 1997-1999. Scent-marking, frontal leadership (time and frequency in the lead while traveling), initiation of activity, and nonfrontal leadership were recorded during 499 h of ground-based observations in Yellowstone National Park. All observed scent-marking (N = 158) was done by breeding wolves, primarily dominant individuals. Dominant breeding pairs provided most leadership, consistent with a trend in social mammals for leadership to correlate with dominance. Dominant breeding wolves led traveling packs during 64% of recorded behavior bouts (N = 591) and 71% of observed travel time (N = 64 h). During travel, breeding males and females led packs approximately equally, which probably reflects high parental investment by both breeding male and female wolves. Newly initiated behaviors (N = 104) were prompted almost 3 times more often by dominant breeders (70%) than by nonbreeders (25%). Dominant breeding females initiated pack activities almost 4 times more often than subordinate breeding females (30 vs. 8 times). Although one subordinate breeding female led more often than individual nonbreeders in one pack in one season, more commonly this was not the case. In 12 cases breeding wolves exhibited nonfrontal leadership. Among subordinate wolves, leadership behavior was observed in subordinate breeding females and other individuals just prior to their dispersal from natal packs. Subordinate wolves were more often found leading packs that were large and contained many subordinate adults. Nous avons analysé le comportement de commandement chez des loups gris (Canis lupus) reproducteurs et non reproducteurs appartenant à trois meutes durant les hivers de 1997-1999. Le marquage d'odeurs, la position en tête de meute (la durée et la fréquence au cours des déplacements), l'initiation des activités et la prise de décisions ailleurs qu'en tête du groupe ont été notés pendant 499 h d'observations au sol dans le Parc national de Yellowstone. Tous les marquages (N = 158) ont été faits par des loups reproducteurs, surtout des individus dominants. Ce sont surtout les couples dominants qui assurent le commandement, en accord avec une tendance chez les mammifères sociaux chez lesquels la fonction de chef est en corrélation avec la dominance. Les loups reproducteurs dominants ont conduit les meutes en déplacement pendant 64 % (N = 591) des épisodes de comportement et pendant 71 % des épisodes de déplacement (N = 64 h). Les mâles et les femelles reproducteurs ont dirigé les meutes en déplacement à peu près également, ce qui reflète probablement l'investissement parental important aussi bien de la part des reproducteurs mâles que des femelles. Les comportements nouveaux (N = 104) ont été adoptés presque trois fois plus souvent par des reproducteurs dominants (70 %) que par des individus non reproducteurs (25 %). Des femelles reproductrices dominantes ont été instigatrices des activités de leur meute environ quatre fois plus souvent que les femelles reproductrices subordonnées (30 vs. 8 fois). Bien qu'une femelle reproductrice subordonnée ait pris la direction de sa meute plus souvent que les individus non reproducteurs au cours d'une saison, cela n'est pas habituel. Dans 12 cas, des loups reproducteurs ont pris la direction de leur meute sans être en tête. Chez les individus subordonnés, le comportement de commandement a été observé chez des femelles reproductrices et chez d'autres individus juste avant qu'ils ne quittent leur meute d'origine au moment de la dispersion. Les loups subordonnés mènent surtout de grands troupeaux qui comptent beaucoup d'individus subordonnés.[Traduit par la Rédaction]

	Title	Comparative Vertebrate Lateralization			Type	Book Whole
	Year	2002	Publication		Abbreviated Journal
	Volume		Issue		Pages
	Keywords
	Abstract	No longer viewed as a characteristic unique to humans, brain lateralization is considered a key property of most, if not all, vertebrates. This field of study provides a firm basis from which to examine a number of important issues in the study of brain and behaviour. This book takes a comparative and integrative approach to lateralization in a wide range of vertebrate species, including humans. It highlights model systems that have proved invaluable in elucidating the function, causes, development, and evolution of lateralization. The book is arranged in four parts, beginning with the evolution of lateralization, moving to its development, to its cognitive dimensions, and finally to its role in memory. Experts in lateralization in lower vertebrates, birds, non-primate mammals, and primates have contributed chapters in which they discuss their own research and consider its implications to humans. The book is suitable for researchers, graduates and advanced undergraduates in psychology, neuroscience and the behavioral sciences. - Unique in its truly comparative approach, covering fish, amphibians, birds, and mammals (including primates and humans) – World-class editors and contributors – Very broad coverage of both theoretical and technical aspects of laterality, including evolution, development, behaviour, and memory Contents Preface; Introduction; Part I.
