| Abstract | Animal innovations range from the discovery of novel food types to the invention of completely novel behaviours. Innovations can give access to new opportunities, and thus enable innovating agents to invade and create novel niches. This in turn can pave the way for morphological adaptation and adaptive radiation. The mechanisms that make innovations possible are probably as diverse as the innovations themselves. So too are their evolutionary consequences. Perhaps because of this diversity, we lack a unifying framework that links mechanism to function. We propose a framework for animal innovation that describes the interactions between mechanism, fitness benefit and evolutionary significance, and which suggests an expanded range of experimental approaches. In doing so, we split innovation into factors (components and phases) that can be manipulated systematically, and which can be investigated both experimentally and with correlational studies. We apply this framework to a selection of cases, showing how it helps us ask more precise questions and design more revealing experiments. | ||||

| Title | The behaviour and managementof Przewalski’shorsesin semi-reserves | Type | Manuscript | ||

Phd thesis | Abbreviated Journal | |

| Abstract | In recent years, Przewalski’s horses have been increasingly kept in semi-reserves. However,there areonly few studies ontheir behaviour and their ability to adaptto management interventions.In the main part of my dissertation, I focus on investigatingthe animals’ behaviour in different semi-reserves with varyinghabitats and living spaces. In addition, I investigate the horses’ behaviour during various management interventionsand analysetheensuing changes instress levels. Another aspect of my dissertation is the studyof social behaviour inPrzewalski’s horses. I investigate theparameters that should be used to demonstrate social bonds between individualsandassess whichdata provide the most meaningful results.In the commentary tochapter 1,several studies investigatingsocial bonds in horsesare discussed. Comparing the various studies, it is strikingthat no homogeneous analyses orevaluation criteria exist. While some authors only considersocial grooming, others include data onthe spatial proximity of the individuals in their evaluations, and various definitionsof proximity can also be found in the literature. Additionally, someauthors use friendly approaches between individuals asa furtherparameter wheninvestigating the social bonds.Continuing with this theme, in chapter 2I investigate the social behaviour of the horses and compare various analysis methods. I show that proactive behaviour, such as friendly approaches, is a good alternative to spatial proximity when investigating social bonds between group members, andis also useful for expanding the often very small data sets of mutual grooming in horses. Comparing Przewalski’s horses with wild living horses, I found no significant differences in the social behavior and the frequency of social interactions, regardlessof group size, group composition, habitat, and individual parameters such as age and gender.Inchapter 3,I investigate the behaviour of a Przewalski’s horse group when exploring a new area of their enclosure. Their behaviour changed, showing less resting and more feeding. Furthermore, the animals maintained greater distances from each other, and the alpha male, instead of herding the group from behind, led the group around the new area and walked in front of the other group members. Moreover, he showed a substantial increase in stress level during the first day.A general comparison of the behaviour of the Przewalski’s horses in different semi-reserves is provided in chapter 4. In it, the habitat choice of the animals and their reactions to various management interventions are investigated. It is shown that Przewalski’s horses prefer open grassland to dense woods, although keeping Przewalski’s horses in a pine forest does not influence the animals’ stress level. In contrast to habitat, food range, and changes in the group composition, which do not appear to change stress levels, individual factors, such as the hierarchy, influence the glucocorticoid level of the animals significantly. The largest increases in stress hormones were demonstrated when the horses were temporarily confined in smaller areas.The importance of the available space is also discussed in chapter 5, where it is shown that horses show less aggressive behaviour when more space is provided. In contrast, the husbandry system does not influence the animals’ aggression, but the way of feeding can additionally reduce agonistic behaviour, for example if food is offered ad libitum.In summary, the results of this study provide indications for the optimization of keeping Przewalski’s horses in semi-reserves. The animals can adapt themselves to the environment and thrive in habitats which do not correspond to their original steppe-like home. Nevertheless, the semi-reserves should provide sufficient grassland, as the horses prefer this type of habitat. General speaking, any types of habitat can only offer a suitable living space if the food range is sufficient for the number of horses. Otherwise, and especially during could winter months, supplementary feeding is necessary according to the body condition of the animals. This is particularly important for older, weakened, or very young animals, which are still adapting to life in the semi-reserve. Without sufficient food, stress hormones can increase and negatively influence the well-being of the horses. The same is true for management interventions: restricting the animals to small enclosures, for example, can adversely affect the horses’ well-being and should be only done if absolutely necessary. Targetedbehaviour observations allow the animals that have a special meaning for the group to be identified, and these should not be taken out of the group unless it is unavoidable, as young and unexperienced horses orientate themselves on those animals. This is especially true for the alpha male in a bachelor group, as these groups are often composed of young horses and the alpha-male provides the necessary stability and experience. Social bonds between individuals can be investigated by observing friendly and proactive behaviour, and social grooming and friendly approaches yield suitable data for such analysis. | ||||

| Abstract | Horses involved in road traffic accidents (RTAs) are commonly presented to veterinarians with varying types of injuries. The aim of this study was describe the pattern and severity of traffic accident-related injuries in horses in a single hospital population. Medical records of horses either hit by a motorized vehicle or involved in RTAs whilst being transported from 1993 to 2015 were retrospectively reviewed and the following data was extracted: Signalement, hospitalisation time, month in which the accident happened, cause of the accident, place of the accident and type of vehicle hitting the horse. Further the different body sites injured (head, neck, breast, fore limb, abdomen, back and spine, pelvis and ileosacral region, hind limb, tail and genital region), the type of injury (wounds, musculoskeletal lesions and internal lesions) and the presence of neurological signs were retrieved from the medical records. 34 horses hit by motorized vehicles and 13 horses involved in RTAs whilst being transported were included in the study. Most of the accidents where horses were hit by motorized vehicles occurred during December (14.7%) and October (14.7%), horses were most commonly hit by cars (85.3%) and the majority of accidents occurred on main roads (26.5%). In 29.4% of the cases, horses had escaped from their paddock and then collided with a motorized vehicle. Most of the accidents with horses involved in RTAs whilst being transported occurred during April (30.8%) and June (23.1%). In 76.9% of the cases the accident happened on a freeway. In the horses hit by motorized vehicles the proximal hind limbs were the body site most commonly affected (44.1%), followed by the proximal front limbs (38.2%) and the head (32.4%). When horses were involved in RTAs whilst being transported the proximal fore limbs (61.5%), the proximal hind limbs (53.8%) and the distal hind limbs, back and head (38.5% each) were the most common injured body sites. Wounds were the most common type of injury in both groups (85.3% hit by motorized vehicle, 76.9% transported ones). In horses hit by a motorized vehicle 35.3% suffered from fractures, in 20.6% a synovial structure was involved and in 5.9% a tendon lesion was present. 14.7% suffered from internal lesions and 14.7% showed neurologic symptoms (40% peripheral, 60% central neurologic deficits). On the other hand, in horses involved in a RTA whilst being transported 30.8% suffered from fractures. There were no synovial structures injured and no tendon injuries were present. Furthermore there were no internal lesions present and only one horse involved in a RTA showed central neurologic symptoms. Injuries of horses being hit by a motorized vehicle were more severe than when horses were protected by a trailer and involved in a RTA whilst being transported. The study has been able to identify the different injury types of traffic accident-related injuries in horses. Awareness of the nature of these injuries is important, to avoid underestimation of their severity. |
