  Title Social learning in dogs: the effect of a human demonstrator on the performance of dogs in a detour task Type Journal Article
  Year 2001 Publication Animal Behaviour. Abbreviated Journal Anim. Behav.  
  Volume 62 Issue 6 Pages 1109-1117  
  Keywords (up)  
  Abstract We recorded the behaviour of dogs in detour tests, in which an object (a favourite toy) or food was placed behind a V-shaped fence. Dogs were able to master this task; however, they did it more easily when they started from within the fence with the object placed outside it. Repeated detours starting from within the fence did not help the dogs to obtain the object more quickly if in a subsequent trial they started outside the fence with the object placed inside it. While six trials were not enough for the dogs to show significant improvement on their own in detouring the fence from outside, demonstration of this action by humans significantly improved the dogs' performance within two-three trials. Owners and strangers were equally effective as demonstrators. Our experiments show that dogs are able to rely on information provided by human action when confronted with a new task. While they did not copy the exact path of the human demonstrator, they easily adopted the detour behaviour shown by humans to reach their goal.

  Title Saving energy during hard times: Energetic adaptations of Shetland pony mares Type Journal Article
  Year 2014 Publication The Journal of Experimental Biology Abbreviated Journal J. Exp. Biol.  
  Volume 217 Issue Pages 4320-4327  
  Keywords (up)  
  Abstract Recent results suggest that wild Northern herbivores reduce their metabolism during times of low ambient temperatures and food shortage in order to reduce their energetic needs. It is however not known if domesticated animals are also able to reduce their energy expenditure. We exposed ten Shetland pony mares to different environmental conditions (summer and winter) and to two food quantities (60 and 100% of maintenance energy requirement, respectively) during low winter temperatures to examine energetic and behavioural responses. In summer ponies showed a considerably higher field metabolic rate (FMR) (63.4±15.0 MJ d-1) compared to restrictively fed and control animals in winter (24.6±7.8 MJ d-1 and 15.0±1.1 MJ d-1, respectively). During summer conditions locomotor activity, resting heart rates and total water turnover were considerably elevated (P<0.001) compared to winter. Restrictively fed animals (N=5) compensated for the decreased energy supply by reducing their FMR by 26% compared to control animals (N=5). Furthermore, resting heart rate, body mass and body condition score were lower (29.2±2.7 beats min-1; 140±22 kg; 3.0±1.0 points) than in control animals (36.8±41 beats min-1; 165 ±31 kg; 4.4±0.7 points; P<0.05). While the observed behaviour did not change, nocturnal hypothermia was elevated. We conclude that ponies acclimatize to different climatic conditions by changing their metabolic rate, behaviour and some physiological parameters. When exposed to energy challenges, ponies, like wild herbivores, exhibited hypometabolism and nocturnal hypothermia.

  Title Fallstudie zum Platzangebot, Verhalten und Wohlbefinden der Pferde (Equus caballus) in Mehrraum-Außenlaufställen mit Aus-lauf und Bewegungsställen [A case study to space, behavior and well-being of horses (Equus caballus) in open stables and open active stables] Type Manuscript
  Year 2014 Publication KTBL Schriften Abbreviated Journal  
  Volume Issue Pages  
  Keywords (up)  
  Abstract Verhaltensbeobachtungen erfolgten an 112 Pferden in Mehrraum-Außenlaufställen mit Auslauf und Bewegungsställen. Bei vermehrtem Platzangebot sinkt das agonistische Verhalten in Bewegungsställen außerhalb des Fressbereiches. Mit zunehmender Stallgröße (überdachte Fläche und Auslauf) steigt in beiden Haltungsverfahren das affiliative Verhalten während das agonistische Verhalten mit Verletzungsrisiko sinkt. Daher wird für beide Haltungsverfahren ein möglichst großzügiger Stall je Pferd empfohlen. Die beobachteten Erkrankungen der letzten zwölf Monate zeigen vermehrt Hautkrankheiten in den Mehrraum-Außenlaufställen mit Auslauf, wohingegen Hufgeschwüre in Bewegungsställen auftraten. Wird der Fütterungsaspekt in den Bewegungsställen betrachtet, so ist die Transponderfütterung in Kombination mit ad libitum Fütterung aufgrund des deutlich geringeren, agonistischen Verhaltens beim Fressen, der reinen Transponderfütterung vorzuziehen. Mehrraum-Außenlaufställe mit Auslauf haben den Vorteil der synchronen Nahrungsaufnahme.

[The behaviour of 112 horses was observed in open stables and open active stables. Horses show less agonistic behaviour outside of the feeding area in open active stables as the space for each horse is augmented. Also the affiliative behaviour increases as a function of more space per horse while agonistic behaviour with a risk for injury decreases. These results are independent from the husbandry system. Due to this fact a stable with a larger area per horse is recommended. Diseases of the last twelve month were recorded and show skin diseases in open stables and abscesses in the hooves in open active stables. To consider the feeding in open active stables it was found that horses which were fed with hay controlled by transponders showed more agonistic behaviour in contrast to horses being fed using transponders but with access to hay ad libitum. Thus transponder feeding in combination with ad libitum feeding is recommended. Open stables have the advantage of synchronized feeding.]

  Title Ancient genomes revisit the ancestry of domestic and Przewalski's horses Type Journal Article
  Year 2018 Publication Science Abbreviated Journal  
  Volume 360 Issue 6384 Pages 111-114  
  Keywords (up)  
  Abstract The Eneolithic Botai culture of the Central Asian steppes provides the earliest archaeological evidence for horse husbandry, ~5,500 ya, but the exact nature of early horse domestication remains controversial. We generated 42 ancient horse genomes, including 20 from Botai. Compared to 46 published ancient and modern horse genomes, our data indicate that Przewalski's horses are the feral descendants of horses herded at Botai and not truly wild horses. All domestic horses dated from ~4,000 ya to present only show ~2.7% of Botai-related ancestry. This indicates that a massive genomic turnover underpins the expansion of the horse stock that gave rise to modern domesticates, which coincides with large-scale human population expansions during the Early Bronze Age.

  Title Lateralization of mother&#65533;infant interactions in a diverse range of mammal species Type Journal Article
  Year 2017 Publication Nature Ecology & Evolution Abbreviated Journal Nat Ecol Evol  
  Volume 1 Issue Pages 0030 Ep -  
  Keywords (up)  
  Abstract Left-cradling bias is a distinctive feature of maternal behaviour in humans and great apes, but its evolutionary origin remains unknown. In 11 species of marine and terrestrial mammal, we demonstrate consistent patterns of lateralization in mother&#65533;infant interactions, indicating right hemisphere dominance for social processing. In providing clear evidence that lateralized positioning is beneficial in mother&#65533;infant interactions, our results illustrate a significant impact of lateralization on individual fitness.

  Title What do wild saiga antelopes tell us about the relative roles of the two brain hemispheres in social interactions? Type Journal Article
  Year 2019 Publication Animal Cognition Abbreviated Journal Anim. Cogn.  
  Volume Issue Pages  
  Keywords (up)  
  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 An evaluation of long-term preservation methods for brown bear (Ursus arctos) faecal DNA samples Type Journal Article
  Year 2002 Publication Conservation Genetics Abbreviated Journal Conservat. Genet.  
  Volume 3 Issue 4 Pages 435-440  
  Keywords (up)  
  Abstract Relatively few large-scale faecal DNA studieshave been initiated due to difficulties inamplifying low quality and quantity DNAtemplate. To improve brown bear faecal DNA PCRamplification success rates and to determinepost collection sample longevity, fivepreservation methods were evaluated: 90%ethanol, DETs buffer, silica-dried, oven-driedstored at room temperature, and oven-driedstored at -20 °C. Preservationeffectiveness was evaluated for 50 faecalsamples by PCR amplification of a mitochondrialDNA (mtDNA) locus (~146 bp) and a nuclear DNA(nDNA) locus (~200 bp) at time points of oneweek, one month, three months and six months. Preservation method and storage timesignificantly impacted mtDNA and nDNAamplification success rates. For mtDNA, allpreservation methods had >= 75% success atone week, but storage time had a significantimpact on the effectiveness of the silicapreservation method. Ethanol preserved sampleshad the highest success rates for both mtDNA(86.5%) and nDNA (84%). Nuclear DNAamplification success rates ranged from 26-88%, and storage time had a significant impacton all methods but ethanol. Preservationmethod and storage time should be importantconsiderations for researchers planningprojects utilizing faecal DNA. We recommendpreservation of faecal samples in 90% ethanolwhen feasible, although when collecting inremote field conditions or for both DNA andhormone assays a dry collection method may beadvantageous.
