Title The Role of Nonlinear Coupling in Human-Horse Interaction: a Preliminary Study Type (up) Conference Article
Year 2017 Publication 2016 38th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC) Abbreviated Journal EMBC
Volume Issue Pages
Keywords
Abstract This study focuses on the analysis of humanhorse

dynamic interaction using cardiovascular information

exclusively. Specifically, the Information Theoretic Learning

(ITL) approach has been applied to a Human-Horse Interaction

paradigm, therefore accounting for the nonlinear information

of the heart-heart interplay between humans and horses.

Heartbeat dynamics was gathered from humans and horses

during three experimental conditions: absence of interaction,

visual-olfactory interaction, and brooming. Cross Information

Potential, Cross Correntropy, and Correntropy Coefficient were

computed to quantitatively estimate nonlinear coupling in a

group of eleven subjects and one horse. Results showed a

statistical significant difference on all of the three interaction

phases. Furthermore, a Support Vector Machine classifier

recognized the three conditions with an accuracy of 90:9%.

These preliminary and encouraging results suggest that ITL

analysis provides viable metrics for the quantitative evaluation

of human-horse interaction.

Title A Matter of Degree: Strength of Brain Asymmetry and Behaviour Type (up)
Year 2017 Publication Symmetry Abbreviated Journal Symmetry
Volume Issue Pages
Keywords functional asymmetry; strength of lateralization; direction of lateralization; advantages; disadvantages; vertebrate species; limb preference; eye bias
Abstract Research on a growing number of vertebrate species has shown that the left and right sides of the brain process information in different ways and that lateralized brain function is expressed in both specific and broad aspects of behaviour. This paper reviews the available evidence relating strength of lateralization to behavioural/cognitive performance. It begins by considering the relationship between limb preference and behaviour in humans and primates from the perspectives of direction and strength of lateralization. In birds, eye preference is used as a reflection of brain asymmetry and the strength of this asymmetry is associated with behaviour important for survival (e.g., visual discrimination of food from non-food and performance of two tasks in parallel). The same applies to studies on aquatic species, mainly fish but also tadpoles, in which strength of lateralization has been assessed as eye preferences or turning biases. Overall, the empirical evidence across vertebrate species points to the conclusion that stronger lateralization is advantageous in a wide range of contexts. Brief discussion of interhemispheric communication follows together with discussion of experiments that examined the effects of sectioning pathways connecting the left and right sides of the brain, or of preventing the development of these left-right connections. The conclusion reached is that degree of functional lateralization affects behaviour in quite similar ways across vertebrate species. Although the direction of lateralization is also important, in many situations strength of lateralization matters more. Finally, possible interactions between asymmetry in different sensory modalities is considered.

Title How stallions influence the dynamic of collective movements in two groups of domestic horses, from departure to arrival Type (up) Journal Article
Year 2017 Publication Behavioural Processes Abbreviated Journal Behav. Process.
Volume 142 Issue Pages 56-63
Keywords consensus; herding; polygyny; personal leadership; shared decision
Abstract Abstract The role of leader in polygynous species has been solely attributed to the male for some time, but recent studies shown decision making to be distributed within the group. However, the specific reproductive strategy and behavioural repertoire of males in polygynous species such as horses may mean that these individuals still have the potential to play a specific role during decision-making. To investigate this subject, we thoroughly studied the behaviour of two domestic stallions during collective movements of their group. We found that they initiated rarely and sometimes failed to recruit the entire group. When departing as followers, they did not accelerate the joining process. Both stallions preferentially occupied the rear position and exhibited numerous monitoring behaviours. Herding behaviours were performed by only one stallion and mostly occurred outside movement context. Finally, we removed this herding stallion from its group to evaluate how the group dynamic changed. As a result, half of the collective movements were five times slower and mares were more dispersed in comparison when the stallion was in the group. Overall, our results suggest that, the two stallions maintained their role of group monitors from departure to arrival. Their influence on the movement dynamic was indirect and did not play a specific role in the process of decision making.

Title Responses of urban crows to con- and hetero-specific alarm calls in predator and non-predator zoo enclosures Type (up) Journal Article
Year 2017 Publication Animal Cognition Abbreviated Journal Anim. Cogn.
Volume 20 Issue 1 Pages 43-51
Keywords
Abstract Urban animals and birds in particular are able to cope with diverse novel threats in a city environment such as avoiding novel, unfamiliar predators. Predator avoidance often includes alarm signals that can be used also by hetero-specifics, which is mainly the case in mixed-species flocks. It can also occur when species do not form flocks but co-occur together. In this study we tested whether urban crows use alarm calls of conspecifics and hetero-specifics (jackdaws, Corvus monedula) differently in a predator and a non-predator context with partly novel and unfamiliar zoo animal species. Birds were tested at the Tiergarten Schönbrunn in the city of Vienna by playing back con- and hetero-specific alarm calls and control stimuli (great tit song and no stimuli) at predator (wolf, polar bear) and non-predator (eland antelope and cranes, peccaries) enclosures. We recorded responses of crows as the percentage of birds flying away after hearing the playback (out of those present before the playback) and as the number of vocalizations given by the present birds. A significantly higher percentage of crows flew away after hearing either con- or hetero-specific alarm calls, but it did not significantly differ between the predator and the non-predator context. Crows treated jackdaw calls just as crow calls, indicating that they make proper use of hetero-specific alarm calls. Responding similarly in both contexts may suggest that the crows were uncertain about the threat a particular zoo animal represents and were generally cautious. In the predator context, however, a high percentage of crows also flew away upon hearing the great tit control song which suggests that they may still evaluate those species which occasionally killed crows as more dangerous and respond to any conspicuous sound.

Title Validation of smart textile electrodes for electrocardiogram monitoring in free-moving horses Type (up) Journal Article
Year 2017 Publication Journal of Veterinary Behavior: Clinical Applications and Research Abbreviated Journal J. Vet. Behav.
Volume 17 Issue Pages 19-23
Keywords
Abstract This article focuses on the validation of smart textile electrodes used to acquire electrocardiogram (ECG) signals in horses in a comfortable and robust manner. The performance of smart textile electrodes is compared with standard Ag/AgCl electrodes in terms of the percentage of motion artifacts (MAs, the noise that results from the movement of electrodes against the skin) and signal quality. Seven healthy Standardbred mares were equipped with 2 identical electronic systems for the simultaneous collection of ECGs. One system was equipped with smart textile electrodes, whereas the second was equipped with standard Ag/AgCl electrodes. Each horse was then monitored individually in a stall for 1 hour, without any movement constraints. The ECGs were visually examined by an expert who blindly labeled the ECG segments that had been corrupted by MAs. Finally, the percentage of MAs (MA%) was computed as the number of samples of the corrupted segments over the whole length of the signal. The total MA% was found to be lower for the smart textiles than for the Ag/AgCl electrodes. Consistent results were also obtained by investigating MAs over time. These results suggest that smart textile electrodes are more reliable when recording artifact-free ECGs in horses at rest. Thus, improving the acquisition of important physiological information related to the activity of the autonomic nervous system, such as heart rate variability, could help to provide reliable information on the mood and state of arousal of horses.

Title Social learning across species: horses (Equus caballus) learn from humans by observation Type (up) Journal Article
Year 2017 Publication Animal Cognition Abbreviated Journal Anim. Cogn.
Volume 20 Issue 3 Pages 567-573
Keywords
Abstract This study examines whether horses can learn by observing humans, given that they identify individual humans and orientate on the focus of human attention. We tested 24 horses aged between 3 and 12. Twelve horses were tested on whether they would learn to open a feeding apparatus by observing a familiar person. The other 12 were controls and received exactly the same experimental procedure, but without a demonstration of how to operate the apparatus. More horses from the group with demonstration (8/12) reached the learning criterion of opening the feeder twenty times consecutively than horses from the control group (2/12), and younger horses seemed to reach the criterion more quickly. Horses not reaching the learning criteria approached the human experimenters more often than those that did. The results demonstrate that horses learn socially across species, in this case from humans.

Title Lateralization of mother&#65533;infant interactions in a diverse range of mammal species Type (up) Journal Article
Year 2017 Publication Nature Ecology & Evolution Abbreviated Journal Nat Ecol Evol
Volume 1 Issue Pages 0030 Ep -
Keywords
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 Corticosterone, inflammation, immune status and telomere length in frigatebird nestlings facing a severe herpesvirus infection Type (up) Journal Article
Year 2017 Publication Conservation Physiology Abbreviated Journal Conserv. Physiol.
Volume 5 Issue 1 Pages cow073-cow073
Keywords
Abstract Herpesvirus outbreaks are common in natural animal populations, but little is known about factors that favour the infection and its consequences for the organism. In this study, we examined the pathophysiological consequences of a disease probably attributable to herpesvirus infection for several markers of immune function, corticosterone, telomere length and inflammation. In addition, we assessed whether any markers used in this study might be associated with the occurrence of visible clinical signs of the disease and its impact on short-term survival perspectives. To address our questions, in spring 2015, we collected blood samples from nestlings of the magnificent frigatebird (Fregata magnificens) that were free of any clinical signs or showed visible signs of the disease. We found that the plasma concentration of haptoglobin was strongly associated with the infection status and could predict probabilities of survival. We also found that nestlings with clinical signs had lower baseline corticosterone concentrations and similar telomere length compared with healthy nestlings, whereas we did not find any association of the infection status with innate immune defenses or with nitric oxide concentration. Overall, our results suggest that the plasma concentration of haptoglobin might be a valuable tool to assess survival probabilities of frigatebird nestlings facing a herpesvirus outbreak.
