Title | What do wild saiga antelopes tell us about the relative roles of the two brain hemispheres in social interactions? | Type | Journal Article | ||

Volume | Issue | Pages | |||

Abstract | Two brain hemispheres are unequally involved in the processing of social stimuli, as demonstrated in a wide range of vertebrates. A considerable number of studies have shown the right hemisphere advantage for social processing. At the same time, an approach-withdrawal hypothesis, mainly based on experimental evidence, proposes the involvement of both brain hemispheres according to approach and withdrawal motivation. The present study aimed to test the relative roles of the two hemispheres in social responses displayed in a natural context. Visual biases, implicating hemispheric lateralization, were estimated in the social interactions of saiga antelope in the wild. In individually identified males, the left/right visual field use during approach and withdrawal responses was recorded based on the lateral head/body position, relative to the conspecific. Lateralized approach responses were investigated in three types of interactions, with left visual field bias found for chasing a rival, no bias--for attacking a rival, and right visual field bias--for pursuing a female. In two types of withdrawal responses, left visual field bias was found for retreating after fighting, while no bias was evident in fight rejecting. These findings demonstrate that neither the right hemisphere advantage nor the approach-withdrawal distinction can fully explain the patterns of lateralization observed in social behaviour. It is clear that both brain hemispheres play significant roles in social responses, while their relative contribution is likely determined by a complex set of motivational and emotional factors rather than a simple dichotomous distinction such as, for example, approach versus withdrawal motivation. | ||||

Title | New Caledonian Crows Behave Optimistically after Using Tools | Type | Journal Article | ||
Year | 2019 | Publication | Current Biology | Abbreviated Journal | |
Volume | Issue | Pages | |||
Keywords | tool use; New Caledonian crows; optimism; cognitive bias; animal emotion; intrinsic motivation; comparative cognition | ||||
Abstract | Summary Are complex, species-specific behaviors in animals reinforced by material reward alone or do they also induce positive emotions? Many adaptive human behaviors are intrinsically motivated: they not only improve our material outcomes, but improve our affect as well [1, 2, 3, 4, 5, 6, 7, 8]. Work to date on animal optimism, as an indicator of positive affect, has generally focused on how animals react to change in their circumstances, such as when their environment is enriched [9, 10, 11, 12, 13, 14] or they are manipulated by humans [15, 16, 17, 18, 19, 20, 21, 22, 23], rather than whether complex actions improve emotional state. Here, we show that wild New Caledonian crows are optimistic after tool use, a complex, species-specific behavior. We further demonstrate that this finding cannot be explained by the crows needing to put more effort into gaining food. Our findings therefore raise the possibility that intrinsic motivation (enjoyment) may be a fundamental proximate cause in the evolution of tool use and other complex behaviors. Video Abstract | ||||

Title | Paleogenomics of Animal Domestication | Type | Book Chapter | ||
Year | 2019 | Publication | Paleogenomics: Genome-Scale Analysis of Ancient DNA | Abbreviated Journal | |
Volume | Issue | Pages | 225-272 | ||
Keywords | |||||
Abstract | Starting with dogs, over 15,000 years ago, the domestication of animals has been central in the development of modern societies. Because of its importance for a range of disciplines – including archaeology, biology and the humanities – domestication has been studied extensively. This chapter reviews how the field of paleogenomics has revolutionised, and will continue to revolutionise, our understanding of animal domestication. We discuss how the recovery of ancient DNA from archaeological remains is allowing researchers to overcome inherent shortcomings arising from the analysis of modern DNA alone. In particular, we show how DNA, extracted from ancient substrates, has proven to be a crucial source of information to reconstruct the geographic and temporal origin of domestic species. We also discuss how ancient DNA is being used by geneticists and archaeologists to directly observe evolutionary changes linked to artificial and natural selection to generate a richer understanding of this fascinating process. | ||||

Title | Stressbelastung bei Pferden in Abhängigkeit des Haltungssystems | Type | Manuscript | ||
Year | 2009 | Publication | Abbreviated Journal | ||
Volume | Issue | Pages | |||
Keywords | |||||
Abstract | Pferdegerechte Haltungssysteme spielen bei der heutigen Nutzung des Freizeit- oder Sportpartners Pferd eine wichtige Rolle, da naturnahe Haltungsbedingungen nur in seltenen Fällen zu realisieren sind. Sämtliche Aufstallungsformen müssen als Kompromiss angesehen werden und bieten somit Vor- und Nachteile. Die vorliegende Untersuchung verfolgte den Zweck, die Stressbelastung von Pferden in verschiedenen Haltungssystemen zu erfassen und vergleichend zu beurteilen. Während der von Mai 2006 bis Juli 2007 durchgeführten Versuche wurden 24 zwei- bis dreijährige Hannoveranerstuten für jeweils 4 Wochen in insgesamt 6 verschiedenen Haltungsformen aufgestallt. Die Haltungsvarianten beinhalteten die Einzelbox (Variante 1), die Einzelbox mit einem frei zugänglichem Paddock (Variante 2), die gemeinsame Haltung von zwei Pferden in zwei Boxen und einem angeschlossenen frei zugänglichem Auslauf (Variante 3) und die Gruppenhaltung von 6 Pferden in einer Mehrraumauslaufhaltung (Variante 4 – 6). Die Haltungsvariante 4 differierte von den Varianten 5 und 6 durch seinen ungegliederten Liegebereich. In den Variante 5 und 6 wurde der Liegebereich der Gruppenhaltung durch eine über die halbe Breite reichende Trennwand in zwei Bereiche unterteilt. Die Trennwand befand sich in Haltungsvariante 5 im rechten Winkel an die Außenwand grenzend, während sie in Variante 6 an der der Stallgasse zugewandten Seite des Liegebereichs aufgestellt wurde. Um eine Vergleichbarkeit mit einem Reitpferd zu schaffen, wurden alle Pferde in allen Haltungssystemen täglich für circa eine Stunde in einer Freilaufanlage bewegt. Die Stressbelastung wurde mittels der Messung der Herzfrequenzvariabilität (Parameter pNN50 und SD1) und der Bestimmung fäkaler Cortisolmetaboliten erfasst. Zusätzlich wurden Videoauswertungen hinsichtlich der Beobachtung von Verhaltensauffälligkeiten in den Haltungsvarianten 1 und 2 durchgeführt. Die durchschnittlich niedrigste Stressbelastung erfuhren die Pferde durch die Haltungsvarianten 4 (pNN50: 46,32 %, SD1:158,58 ms, Cortisolmetaboliten: 21,01nmol/kg Kot) und 6 (pNN50: 47,1 %, SD1: 144,62 ms, Cortisolmetaboliten: 21,01 nmol/kg Kot). Die 141 Auswertung der pNN50- und Cortisolmetabolitenwerte ergab die größte Stressbelastung der Pferde in den Varianten 1 (pNN50: 42,81 %, SD1: 134,52 ms, Cortisolmetaboliten: 28,56 nmol/kg Kot) und 3 (pNN50: 42,41 %, SD1: 135,36, Cortisolmetaboliten: 28,60 nmol/kg Kot). Die Auswertung der SD1-Werte zeigte zusätzlich noch eine hohe Stressbelastung der Pferde in der Variante 5 (pNN50: 44,83 %, SD1: 119,24 ms, Cortisolmetaboliten: 27,18 nmol/kg Kot). Die Haltungsvariante 2 (pNN50: 45,77 %, SD1: 144,25 ms, Cortisolmetaboliten: 27,59 nmol/kg Kot) beziehungsweise die Varianten 2 und 5 (bei der Betrachtung der pNN50- und der Cortisolmetabolitenwerte) verursachten im Durchschnitt eine mittlere Stressbelastung. Teilweise waren die Unterschiede jedoch zu gering um die Signifikanzgrenze zu überschreiten. Die Betrachtung der einzelnen Pferde und der Pferdegruppen ergab große interindividuelle Unterschiede und deutliche gruppenspezifische Gemeinsamkeiten. Die Position eines Tieres in der Rangordnung hatte in diesen Untersuchungen bei der Betrachtung der Mittelwerte keinen Einfluss auf die Stressbelastung in Abhängigkeit der Haltungsvariante. Vielmehr zeigten sich auch hier deutliche individuelle Unterschiede in der Stressanfälligkeit und den Vorlieben der einzelnen Pferde bezüglich der verschiedenen Haltungssysteme. Die Analyse der Videoaufzeichnungen ergab, dass mehrere Pferde Kreisbewegungen in der Einzelbox ohne Auslauf (Variante 1) zeigten, während in der Variante 2 (Paddockbox) kein Pferd durch Kreisbewegungen auffiel. Andere Verhaltensauffälligkeiten oder gar Verhaltensstörungen wurden nicht beobachtet. Bei der Auswertung der Aufenthaltshäufigkeit und der Aufenthaltesdauer in den 4 Boxenquadranten zeigten sich einige Pferde sehr aktiv, was ein Hinweis auf eventuelle Unruhe oder Nervosität sein kann, während andere Pferde im Vergleich zum Gruppendurchschnitt sehr ruhig wirkten, da sie sich in der Box kaum bewegten und über lange Zeitabschnitte in einem Quadranten standen. Obwohl die Gruppenhaltung für die Mehrzahl der Pferde eine geringere Stressbelastung bedeutete und auch hinsichtlich des Bewegungs- und Sozialverhaltens am artgerechtesten einzustufen ist, sollte für jedes Pferd individuell unter Berücksichtigung seines Alters, seiner Rasse, seines Nutzungsgrades, aber vor allem seines Charakters und seiner Erfahrungen im Sozialverhalten ein passendes großzügig bemessenes Haltungssystem ermittelt werden, um 142 die durch das Haltungssystem ausgeübte Stressbelastung zu minimieren und das Wohlbefinden der Pferde zu steigern. |
