Abstract |
Two contrasting results emerge from comparisons of the social systems of several odontocetes with terrestrial mammals. Researchers have identified remarkable convergence in prominent features of the social systems of odontocetes such as the sperm whale and bottlenose dolphin with a few well-known terrestrial mammals such as the elephant and chimpanzee. In contrast, studies on killer whales and Baird's beaked whale reveal novel social solutions to aquatic living. The combination of convergent and novel features in odontocete social systems promise a more general understanding of the ecological determinants of social systems in both terrestrial and aquatic habitats, as well as the relationship between relative brain size and social evolution. |

Abstract |
Imitation and innovation work in tandem to support cultural learning in children and facilitate our capacity for cumulative culture. Here we propose an integrated theoretical account of how the unique demands of acquiring instrumental skills and cultural conventions provide insight into when children imitate, when they innovate, and to what degree. For instrumental learning, with an increase in experience, high fidelity imitation decreases and innovation increases. By contrast, for conventional learning, imitative fidelity stays high, regardless of experience, and innovation stays low. We synthesize cutting edge research on the development of imitative flexibility and innovation to provide insight into the social learning mechanisms underpinning the uniquely human mind. |

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.] |

Abstract |
Ziel: Überprüfung der Tiergerechtheit von in der Bauweise unterschiedlichen
Futterabrufstationen für Pferde in Gruppenhaltung anhand ethologischer
und physiologischer Parameter. Material und Methoden: In 32
Offenlaufställen (452 Pferde) mit computergesteuerten Abrufstationen
für Kraftfutter und Heu erfolgten kontinuierliche Direktbeobachtungen
für je einen 24-Stunden-Tag (Tortenstückverfahren). Erfasst wurden: Aufenthaltsdauer,
Besuchshäufigkeit, Droh- und Meideverhalten im Fütterungsbereich,
Blockaden sowie Herzfrequenz und Integumentverletzungen.
Ergebnisse: Eine Durchlaufstation reduzierte die Zahl der Auseinandersetzungen
im Fütterungsbereich signifikant. Ansonsten erhöhten die
für das fressende Pferd tiergerechten Varianten (Fressstand mit Eingangssperre,
ohne Austreibehilfe) Besuchshäufigkeit und Aufenthaltsdauer und
steigerten somit auch die Anzahl an Drohgesten je Tier und Tag. Insgesamt
betrachtet kann jedoch die Anzahl an sozionegativen Interaktionen
im Fütterungsbereich der Abrufstationen als relativ gering eingestuft
werden. Die Herzfrequenz lag im Warteareal bei den meisten Pferden im
physiologischen Bereich (45,1 ± 12,42 Schläge/min), erhöhte sich jedoch
in der Abrufstation um ca. 20 Schläge/min. Einige Tiere zeigten möglicherweise
stressbedingt kurzfristig auffallend hohe Werte (≥ 100 Schläge/
min). Integumentverletzungen im Zusammenhang mit dem Fütterungssystem
traten nicht auf. Der wichtigste Einflussfaktor auf die Untersuchungskriterien
war der Betrieb (Fläche, Konzeption, Management).
Schlussfolgerung: Durchlaufstationen sind pferdegerechter als Rücklaufstationen.
Nicht tiergerecht sind Stationen mit stromführender Austreibehilfe.
Weitere bauliche Unterschiede der derzeitigen Futterabrufstationen
dürften eher von untergeordneter Bedeutung sein, vor allem da
Flächengebot und Konzeption der Offenstallanlage sowie das Management
die überprüften Kriterien zur Tiergerechtheit maßgeblich beeinflussen.
Untersuchungen zur Abklärung der Ursache für die vereinzelt aufgetretenen
sehr hohen Herzfrequenzwerte sollten durchgeführt werden.
Objective: Comparison with regard to animal welfare of different automatic
feeding systems for hay and concentrate in group housing systems
for horses using parameters of ethology and physiology. Material and
methods: Parameters of research comprised: duration of stay, frequency
of visit, threatening behaviour with and without risk of injury, and avoiding
behaviour as well as heart rate and injuries of the integument. 452
horses were observed at the feeding area of 32 run-out-sheds. Every group
of horses was continuously observed following the pie chart system for
24 hours. Results: The “walk-through” station significantly reduced the
number of conflicts in the feeding area, whereas those systems which are
appropriate for the feeding horses (feeding station with access barrier and
without stimulation device by electric shock) led to a higher frequency of
visits and a longer duration of stay resulting in more threatening gestures.
However, the number of negative interactions in the feeding area of the
feeding systems can all together be classified as relatively insignificant.
The heart rate was within the physiological range (45.1 ± 12.42 beats/min)
in the waiting area, but increased by approximately 20 beats/min on average
within the feeding station. Some horses showed a very high heart rate
(≥ 100 beats/min) while entering the feeding station, possibly stress-related.
There were no injuries of the integument associated with the feeding
systems. The most important factor of the observation criteria was the
individual group housing system with its different dimensions, conception
and management. Conclusion: “Walk-through” stations are better than
”walk-back” stations with regard to animal welfare. Likewise, automatic
feeding stations with a current-carrying stimulation device are not supportive
of good welfare. The other differences between the constructions
of feeding stations of present systems are probably of less importance, particularly
as it was shown that the stable (management, stable area, conception)
had a significant influence on the surveyed parameters. Investigations
to obtain information on the cause for the sporadic occurrence of
very high heart rate values should be undertaken.] |

Abstract |
Zusammenfassung
Gegenstand und Ziel Seit 2000 siedelt sich der Wolf in Deutschland wieder an. Mit steigenden Wolfszahlen nehmen die durch Wölfe verursachten Nutztierschäden zu, wobei auch Pferde betroffen sind. Ziel der Studie war es, einen Überblick zu dieser Problematik sowie Lösungsansätze zu geben.
Material und Methoden Anhand einer Literaturrecherche wurden Daten zur Wolfspopulation in Deutschland, wolfsbedingten Schäden sowie Möglichkeiten und Grenzen des Herdenschutzes beim Pferd eruiert. Eine Online-Befragung von Pferdehaltern/-besitzern diente dazu, die tatsächliche und/oder gefühlte Bedrohung durch Wölfe und die daraus resultierenden Auswirkungen auf die Pferdehaltung zu ermitteln.
Ergebnisse Die Literaturrecherche zeigte ein kontinuierliches Anwachsen der Wolfspopulation in den letzten Jahren und insbesondere seit 2016 einen deutlichen Anstieg wolfsverursachter Nutztierschäden, wobei Pferde selten betroffen waren. Bei der Online-Befragung stammte die Hälfte der 574 ausgewerteten Fragebögen aus Brandenburg und Niedersachsen. Den größten Einfluss auf die Gefährdungsbeurteilung eigener Pferde durch die wachsende Wolfspopulation hatte das Wissen der Pferdehalter über Wolfsangriffe im eigenen Landkreis, wobei insbesondere die Aspekte einer Haltung von Jungpferden und Weidegang für die Pferde eine Rolle spielten. 64 % der Befragten gaben an, ihre Pferdehaltung trotz der zunehmenden Wolfspopulation nicht geändert zu haben. Nur 8 von 576 Pferdehaltern gaben amtlich bestätigte Wolfsübergriffe an und 30 hatten einen vermuteten Wolfsschaden amtlichen Stellen nicht gemeldet. Mehr als die Hälfte der Befragten, die Kontakt zu einem Wolfsberater hatten, bezeichneten die Zusammenarbeit als nicht bis wenig zielführend.
Schlussfolgerung und klinische Relevanz Die Zahl amtlich bestätigter Wolfsangriffe auf Pferde ist gering. Durch einen grundsätzlich durchgeführten Gentest bei entsprechendem Verdacht ließen sich diese Zahlen objektivieren. Trotz des Bewusstseins einer zunehmenden Gefährdung von Pferden durch Wölfe unternehmen Pferdehalter überwiegend keine prophylaktischen Schutzmaßnahmen. Die Kommunikation zwischen den für das Wolfsmonitoring zuständigen Behörden und den Pferdehaltern erscheint verbesserungswürdig.
Abstract
Objective Since 2000 the wolf population is reestablishing itself in Germany. In consequence to increasing numbers, livestock damage caused by wolves is on the rise, with horses likewise being affected. The aim of the study was to provide an overview of this challenge and its possible solutions.
Material and methods Based on a literature research, data on the wolf population in Germany, wolf-related damage as well as possibilities and limitations of herd protection for horses were evaluated. An online survey addressed to horse owners/keepers served to determine the actual and/or perceived threat posed by wolves and the resulting effects on horse husbandry.
Results The literature search showed a continuous increase of the wolf population in recent years as well as a significant increase of wolf-caused livestock damage in general especially since 2016; although horses were rarely affected. Half of the 574 evaluated questionnaires were from Brandenburg and Lower Saxony. The greatest influence on the individual risk assessment concerning their own horses by the growing wolf population was the horse owners� knowledge of wolf attacks in their own county. Especially the aspects of keeping young horses as well as pasture keeping played a significant role. 64 % of respondents indicated that they had not changed their horse management practices despite the increasing wolf population. Only 8 of 576 horse owners had reported officially confirmed wolf attacks and 30 respondents had not reported a suspected wolf damage to official agencies. More than half of the respondents who had contact with a wolf advisor described the cooperation as either not or only slightly purposeful.
Conclusion and clinical relevance The number of officially confirmed wolf attacks on horses is low. These numbers could be objectified by a routinely performed genetic test in case of corresponding suspicion. Despite the awareness of an increasing danger of horses by wolves, horse owners mostly do not undertake prophylactic protection measures. The communication between responsible authorities for wolf monitoring and horse owners seems to be in need of improvement. |

Abstract |
1. Models on territory acquisition and tenure predict that territorial animals benefit by adjusting territorial defence behaviour to previous challenges they had experienced within the socially complex environment of communication networks. 2. Here, we addressed such issues of social cognition by investigating persisting effects of vocal contests on territory defence behaviour in nightingales Luscinia megarhynchos (Brehm). 3. Using interactive playback during nocturnal song of subjects, a rival was simulated to countersing either aggressively (by song overlapping) or moderately (by song alternating) from outside the subjects' territory. Thereby, the time-specific singing strategy provided an experimentally controlled source of information on the motivation of an unfamiliar rival. 4. Expecting that nightingales integrate information with time, the same rival was simulated to return as a moderately singing intruder on the following morning. 5. The results show that the vigour with which male nightingales responded to the simulated intrusion of an opponent during the day depended on the nature of the nocturnal vocal interaction experienced several hours before. 6. Males that had received the song overlapping playback the preceding night approached the simulated intruder more quickly and closer and sang more songs near the loudspeaker than did males that had received a song alternating playback. 7. This adjustment of territory defence strategies depending on information from prior signalling experience suggests that integrating information with time plays an important part in territory defence by affecting a male's decision making in a communication network. |
