  Title Aggressionslevel und Platzangebot bei Pferden (Equus caballus) [ Aggression level and enclosure size in horses (Equus caballus)] Type Journal Article
  Year 2013 Publication Pferdeheilkunde Abbreviated Journal  
  Volume (up) 29 Issue 4 Pages 495-504  
  Keywords Aggression / Verletzungsgefahr / Sozialverhalten / Gruppenhaltung / Pferdehaltung / Eingliederung von Pferden [aggression / injury risk / social behaviour / group housing / horse management / introduction of horses]  
  Abstract Viele Pferdebesitzer bevorzugen aus Angst vor aggressiven Interaktionen und Verletzungsgefahr der Tiere untereinander die Einzelhaltung, obwohl von Tierschutzorganisationen die Gruppenhaltung für Pferde empfohlen wird. In dieser Studie beobachteten wir während des alltäglichen Soziallebens als auch bei der Eingliederung von neuen Gruppenmitgliedern das Sozialverhalten, insbesondere das Aggressionsverhalten, von elf Gruppen domestizierter Pferde (Equus caballus) verschiedener Größe und Zusammensetzung. Während des alltäglichen Soziallebens hatten die Gruppe und der Paddock-Typ (Gras / kein Gras) keinen Einfluss auf die Verhaltensweisen, wohingegen die Paddockgröße unter 10000 m2 einen signifikanten Einfluss auf die submissiven Verhaltensweisen (GzLM; n=56; t=-2.061, P=0.044) und einen nicht signifikanten Einfluss auf die aggressiven Verhaltensweisen (GzLM; n=56; t=-1.782, P=0.081) hatte. Allerdings verringerten sich sowohl die aggressiven als auch die submissiven Verhaltensweisen mit steigendem Platzangebot bis zu 10000 m2 (Spearman rank Korrelation; n=56; aggressive Verhaltensweisen: r = -0.313, P = 0.019; submissive Verhaltensweisen: r = -0.328, P = 0.014). Während den Eingliederungen reduzierten sich die Aggressionen pro Stunde mit der Vergrößerung des Platzangebotes (Spearman rank Korrelation; n=28; r=-0.402, P=0.034). Dies zeigte sich noch deutlicher, wenn Beobachtungen mit einem Platzangebot von über 10000 m2 ausgeschlos- sen wurden (Spearman rank Korrelation; n=23; r=-0.549, P=0.007). Während des alltäglichen Soziallebens näherte sich der Aggressionslevel der Nulllinie an, wenn das Platzangebot pro Pferd mehr als 331 m2 betrug. Deshalb empfehlen wir zur Reduzierung des Aggressionslevels und des Verletzungsrisikos von sozial gehaltenen Pferdegruppen ein Platzangebot von mindestens 331 m2 pro Pferd.

[Even though animal welfare organisations propose group housing for horse welfare, many owners stable horses individually for fear of aggressive interactions and injury risks. In the present study we observed social behaviour, and especially aggressiveness, in eleven domestic horse groups (Equus caballus) of different size and composition, in basic social situations and when new group members were introduced. During basic social situations, the group and the type of paddock (grass / no grass) had no effect on any of the behaviours, where- as the enclosure size below 10,000 m2 had a significant effect on submissive behaviour (GzLM; n=56; t=-2.061, P=0.044) and an insignificant effect on aggressive behaviour (GzLM; n=56; t=-1.782, P=0.081). However, aggressive and submissive behaviour dimi- nished with the increase of enclosure sizes up to 10,000 m2 (Spearman rank correlation; n = 56; aggressive behaviour: r = -0.313, P=0.019; submissive behaviour: r=-0.328, P=0.014). During introductions, aggression levels per hour decreased with any increase of enclosure size (Spearman rank correlation; n=28; r=-0.402, P=0.034) and even more when enclosure sizes above 10,000 m2 were excluded (Spearman rank correlation; n=23; r=-0.549, P=0.007). During basic social situations the aggression level approached zero when the space allowance was more than 331 m2 per horse. We therefore recommend keeping horse groups in an enclosure with at least 331 m2 per horse to reduce aggression and injuries.]

  Title How “natural” training methods can affect equine mental state? A critical approach -- a review Type Journal Article
  Year 2013 Publication Animal Science Papers & Reports Abbreviated Journal  
  Volume (up) 31 Issue 3 Pages 185  
  Keywords HORSES -- Training; HORSEMANSHIP; HUMAN-animal relationships; LEARNING in animals; ANIMAL psychology; ANIMAL intelligence; ANIMAL welfare  
  Abstract Among equestrians the “natural” training methods of horses are gaining widespread popularity due to their spectacular efficiency. Underlying philosophy of trainers – founders of different “natural horsemanship training” (NHT) schools, along with other not well documented statements includes argumentation of solely welfare- and human-friendly effects of NHT in the horse. The aim of this review was to screen scientific papers related to NHT to answer the question whether „natural“ training methods may actually exert only positive effects upon equine mental state and human-horse relationship. It appears that NHT trainers may reduce stress and emotional tension and improve learning processes as they appropriately apply learning stimuli. Basing on revised literature it can be concluded that training is successful provided that [i] the strength of the aversive stimulus meets sensitivity of an individual horse, [ii] the aversive stimulus is terminated at a right moment to avoid the impression of punishment, and [iii] the animal is given enough time to assess its situation and make an independent decision in the form of adequate behavioural reaction. Neglecting any of these conditions may lead to substantial emotional problems, hyperactivity, or excessive fear in the horse-human relationship, regardless of the training method. However, we admit that the most successful NHT trainers reduce aversive stimulation to the minimum and that horses learn quicker with fear or stress reactions, apparently decreasing along with training process. Anyway, NHT should be acknowledged for absolutely positive role in pointing out the importance of proper stimulation in the schooling and welfare of horses.

  Title Sexual experience increases oxytocin receptor gene expression and protein in the medial preoptic area of the male rat Type Abstract
  Year 2013 Publication Psychoneuroendocrinology Abbreviated Journal Psychoneuroendocrinology  
  Volume (up) 38 Issue 9 Pages 1688-1697  
  Keywords Oxytocin; Oxytocin receptor; Sexual behavior; Sexual experience; Medial preoptic area; Hypothalamus; Rats  
  Abstract Oxytocin (OT) promotes social and reproductive behaviors in mammals, and OT deficits may be linked to disordered social behaviors like autism and severe anxiety. Male rat sexual behavior is an excellent model for OT regulation of behavior, as its pattern and neural substrates are well characterized. We previously reported that OT microinjected into the medial preoptic area (MPOA), a major integrative site for male sexual behavior, facilitates copulation in sexually experienced male rats, whereas intra-MPOA injection of an OT antagonist (OTA) inhibits copulation. In the present studies, copulation on the day of sacrifice stimulated OTR mRNA expression in the MPOA, irrespective of previous sexual experience, with the highest levels observed in first-time copulators. In addition, sexually experienced males had higher levels of OTR protein in the MPOA than sexually naïve males and first-time copulators. Finally, intra-MPOA injection of OT facilitated mating in sexually naive males. Others have reported a positive correlation between OT mRNA levels and male sexual behavior. Our studies show that OT in the MPOA facilitates mating in both sexually naive and experienced males, some of the behavioral effects of OT are mediated by the OTR, and sexual experience is associated with increased OTR expression in the MPOA. Taken together, these data suggest a reciprocal interaction between central OT and behavior, in which OT facilitates copulation and copulation stimulates the OT/OTR system in the brain.

  Title Opportunistic citizen science data of animal species produce reliable estimates of distribution trends if analysed with occupancy models Type Journal Article
  Year 2013 Publication Journal of Applied Ecology Abbreviated Journal J Appl Ecol  
  Volume (up) 50 Issue 6 Pages 1450-1458  
  Keywords Bayesian inference; citizen science; detection; distribution; hierarchical modelling; Jags; monitoring; site occupancy  
  Abstract Summary Many publications documenting large-scale trends in the distribution of species make use of opportunistic citizen data, that is, observations of species collected without standardized field protocol and without explicit sampling design. It is a challenge to achieve reliable estimates of distribution trends from them, because opportunistic citizen science data may suffer from changes in field efforts over time (observation bias), from incomplete and selective recording by observers (reporting bias) and from geographical bias. These, in addition to detection bias, may lead to spurious trends. We investigated whether occupancy models can correct for the observation, reporting and detection biases in opportunistic data. Occupancy models use detection/nondetection data and yield estimates of the percentage of occupied sites (occupancy) per year. These models take the imperfect detection of species into account. By correcting for detection bias, they may simultaneously correct for observation and reporting bias as well. We compared trends in occupancy (or distribution) of butterfly and dragonfly species derived from opportunistic data with those derived from standardized monitoring data. All data came from the same grid squares and years, in order to avoid any geographical bias in this comparison. Distribution trends in opportunistic and monitoring data were well-matched. Strong trends observed in monitoring data were rarely missed in opportunistic data. Synthesis and applications. Opportunistic data can be used for monitoring purposes if occupancy models are used for analysis. Occupancy models are able to control for the common biases encountered with opportunistic data, enabling species trends to be monitored for species groups and regions where it is not feasible to collect standardized data on a large scale. Opportunistic data may thus become an important source of information to track distribution trends in many groups of species.

  Title Magnetic alignment in mammals and other animals Type Journal Article
  Year 2013 Publication Mammalian Biology – Zeitschrift für Säugetierkunde Abbreviated Journal Mamm. Biol.  
  Volume (up) 78 Issue 1 Pages 10-20  
  Keywords Cattle; Deer; Fox; Horse; Magnetoreception  
  Abstract Magnetic alignment (MA) constitutes the simplest directional response to the geomagnetic field. In contrast to magnetic compass orientation, MA is not goal directed and represents a spontaneous, fixed directional response. Because animals tend to align their bodies along or perpendicular to the magnetic field lines, MA typically leads to bimodal or quadrimodal orientation, although there is also growing evidence for a fixed unimodal orientation not necessarily coinciding with the magnetic cardinal directions. MA has been demonstrated in diverse animals including insects, amphibians, fish, and mammals. Alignment can be expressed by animals during resting as well as on the move (e.g. while grazing, hunting, feeding, etc.). Here, we briefly survey characteristic features and classical examples of MA and review the current knowledge about the occurrence of MA in mammals. In addition, we summarize what is known about mechanisms underlying MA and discuss its prospective biological functions. Finally, we highlight some physiological effects of alignment along the magnetic field axes reported in humans. We argue that the phenomenon of MA adds a new paradigm that can be exploited for investigation of magnetoreception in mammals.

  Title A comparison of innovative problem-solving abilities between wild and captive spotted hyaenas, Crocuta crocuta Type Journal Article
  Year 2013 Publication Animal Behaviour Abbreviated Journal  
  Volume (up) 85 Issue 2 Pages 349-356  
  Keywords Crocuta crocuta; innovation; neophobia; problem solving; spotted hyaena  
  Abstract Innovative problem solving enables individuals to deal with novel social and ecological challenges. However, our understanding of the importance of innovation for animals in their natural habitat is limited because experimental investigations of innovation have historically focused on captive animals. To determine how captivity affects innovation, and whether captive studies of animal innovation suffer from low external validity, we need experimental investigations of innovation in both wild and captive populations of the same species in diverse taxa. Here we inquired whether wild and captive spotted hyaenas differ in their ability to solve the same novel technical problem, and in the diversity of exploratory behaviours they exhibit when first interacting with the problem. Our results suggest that wild and captive populations show important differences in their innovative problem-solving abilities. Captive hyaenas were significantly more successful at solving the novel problem, and significantly more diverse in their initial exploratory behaviour, than were wild hyaenas. We were able to rule out hypotheses suggesting that these differences result from excess energy or time available to captive animals. We conclude that captive hyaenas were more successful because captive individuals were less neophobic and more exploratory than their wild counterparts. These results have important implications for our interpretation of studies on innovative problem solving in captive animals and aid our attempts to gain a broader understanding of the importance of innovation for animals in their natural habitat.

  Title Kosten-Nutzen-Analyse einer objektivierten Temperamentbeurteilung bei Pferden [Economic evaluation of an objective temperament assessment in horses] Type Journal Article
  Year 2013 Publication Züchtungskunde Abbreviated Journal  
  Volume (up) 85 Issue 2 Pages 129-142  
  Keywords Kosten, Nutzen, Interieurbeurteilung, Pferd, Temperament [Economy, personality assessment, horse, temperament]  
  Abstract Das Ziel der vorliegenden Studie war die Ermittlung der Kosten eines Verhaltenstests zur

objektiven Temperamentbeurteilung. Sie wurde an 1028 Pferden auf 55 Zuchtveranstaltungen

und Privatbetrieben ermittelt.

Weiterhin wurde eine Befragung zur allgemeinen Akzeptanz einer solchen Beurteilung

bei Reitpferden durchgeführt. Zusätzlich wurde mit Hilfe einer Online-Umfrage die

Meinung zu den Kosten und dem Aufwand einer solchen Beurteilung ermittelt. Die

Kosten der Einführung einer objektiven Temperamentbeurteilung entsprechen nach Einbeziehung

aller Faktoren ca. 18 Euro je Pferd. Den Kosten steht die Zahlungsbereitschaft

für eine verbesserte, da objektivierte Temperamentbeurteilung gegenüber. Insgesamt

56,7% der Befragten wären bereit, mehr als 11 Euro für eine objektive Interieurbeurteilung

auf Leistungsprüfungen im Feld zu investieren. Im Rahmen von Stationsprüfungen

wären sie sogar bereit mehr als 30 Euro aufzuwenden. Die Wertsteigerung eines im

Rahmen des Verfahrens positiv bewerteten Pferdes um 5%, die von den Teilnehmern der

Umfrage durchschnittlich angenommen wird, würde zusätzlich den Gewinn beim Pferdeverkauf

steigern. Die Ergebnisse zeigen, dass die Kosten einer objektiven Temperamentbeurteilung

durch eine erhöhte Zahlungsbereitschaft der Käufer scheinbar kompensiert

werden können, so dass die Einführung eines Temperamenttests zur objektiven Interieurbeurteilung

in Form der vorgestellten Untersuchungen grundsätzlich finanzierbar ist.

[The aim of the present study was to assess costs as well as riders’ acceptance of an

objective temperament evaluation in riding horses. Costs were determined based on a

novel object test conducted in 1028 horses tested on 65 occasions during performance

tests or in private stables. In addition, an online survey was used to identify riders’

opinion about the costs and benefits of such an assessment. Based on the conditions

assumed in the present study the costs for temperament testing have amount 18 Euro per

horse. More than 50% of the respondents were willing to pay more than 11 Euro for an

objective temperament assessment in their horses during performance tests in field.

Within performance tests on station they would spend more than 30 Euro for an objective temperament assessment. Participants further assumed a rise in value of favourably

assessed horses by 5%, leading to increased profits when selling the horse. In conclusion,

riders appear to be willing to cover the additional costs accrued from the temperament

test. Therefore, the introduction of an objective temperament assessment is likely to pay

off.]

  Title The use of visual media as a tool for investigating animal behaviour Type Journal Article
  Year 2013 Publication Animal Behaviour Abbreviated Journal  
  Volume (up) 85 Issue 3 Pages 525-536  
  Keywords citizen science; crowdsourcing; internet; online resource; opportunistic observation; 'people power'; playback study; preliminary testing; YouTube  
  Abstract In this essay we outline how video-related technology can be used as a tool for studying animal behaviour. We review particular aspects of novel, innovative animal behaviour uploaded by the general public via video-based media on the internet (using YouTube as a specific example). The behaviour of animals, particularly the play behaviour focused on here, is viewed by huge audiences. In this essay we focused on three different kinds of media clips: (1) interspecies play between dogs and a range of other species; (2) object play in horses; and (3) animal responses to stimuli presented on iPads, iPods and iPhones. We argue that the use of video is a good means of capturing uncommon or previously unknown behaviour, providing evidence that these behaviours occur. Furthermore, some of the behaviours featured on YouTube provide valuable insights for future directions in animal behaviour research. If we also take this opportunity to convey our knowledge to a public that seems to be fundamentally interested in animal behaviour, this is a good means of bridging the gap between knowledge among an academic few and the general public.
