| Abstract | In 32 Offenlaufställen mit computergesteuerten Abrufstationen wurden die Aufenthaltsdauer und Besuchshäufigkeit sowie das Droh- und Meideverhalten von 439 Pferden im Füttererungsbereich erfasst. Je Betrieb erfolgten visuelle kontinuierliche Direktbeobachtungen nach dem Tortenstückverfahren (6 x 4 Stunden) für je einen 24-Stunden-Tag. Ziel war die Überprüfung der verschiedenen Bauausführungen der Abrufstationen unter dem Aspekt der Tiergerechtheit. Eine Einwegstation reduzierte signifikant die Anzahl an Auseinandersetzungen im Fütterungsbereich. Demgegenüber führten die für das fressende Pferd tiergerechten Varianten (Fressstand mit Eingangssperre und ohne Austreibehilfe) zu einer Erhöhung der Besuchshäufigkeit und Aufenthaltsdauer und somit auch zu einer erhöhten Anzahl an Drohgesten. Doch insgesamt betrachtet, kann die Anzahl an sozionegativen Interaktionen im Fütterungsbereich der Abrufstationen als relativ gering eingestuft werden. Da sich außerdem der Betrieb (Management, Fläche, Konzeption) als maßgeblicher Einflussfaktor auf die überprüften Parameter erwies, dürften die Unterschiede in der Bauausführung der derzeitigen Abrufstationen für Pferde eher von untergeordneter Bedeutung sein. [Duration of stay, frequency of visit, threatening gestures and behaviour of avoidance of 439 horses was observed at the feeding area of 32 run-out-sheds. The observation was based on the method of visual continuously direct watching after the pie chart system (6 x 4 hours) over a period of 24 hours. The observation should show which construction of the different automatic feeding systems corresponded best under the aspect of animal welfare. It was obvious that the one-way-station reduced significantly the number of conflicts in the feeding area, whereas those systems which are appropriate for the eating horses (feeding station with access barrier and without stimulation device by electric shock) led to a higher frequency of visits and duration of stay as well as to more threatening gestures. Considering altogether, the number of negative interactions in the feeding area of the feeding systems can be classified as comparatively unimportant. As it showed that the stable (management, stable area, conception) was of important influence on the surveyed parameters, the differences between the constructions of feeding stations for horses of present systems are probably of less meaning.] |

| Abstract | Das Droh- und Meideverhalten von 270 Pferden wurde im Fressbereich von 10 Offenlaufställen mit Fressständen und 11 Offenlaufställen mit computergesteuerten Abrufstationen anhand von visuellen kontinuierlichen Direktbeobachtungen erfasst. Diese erfolgten je Betrieb über einen 24-Stunden-Tag, der nach dem Tortenstückverfahren (6x4 Stunden) zusammengesetzt war. Insgesamt wurden 6297 agonistische Verhaltensweisen in, vor und hinter den Fütterungseinrichtungen registriert (Meiden 40,6 %, Verdrängen 12,8 %, Beißen/ Hinterhandschlag/ Angehen 12,7 % und Drohen/ Drohbeißen/ Hinterhanddrohen 33,9 %). In den Futterstationen wurden 22,5 % dieses Verhaltens beobachtet, vor und hinter den Futterstationen 77,5 %. Bei den Betrieben mit Fressständen fanden 31 % der agonistischen Verhaltensweisen in den Ständen statt, bei den Betrieben mit Abruffütterung 21 %. Der Einfl uss des einzelnen Betriebes (innerhalb Fütterungssystem) auf die agonistischen Verhaltensweisen vor und hinter den Fütterungseinrichtungen war signifi kant. Die Auswertung ergab, dass Drohgesten im Wartebereich von Abrufstationen häufi ger auftreten als in dem von Fressständen. Demgegenüber können Pferde in Abrufstationen ungestörter fressen. Insgesamt betrachtet war jedoch die Anzahl an sozionegativen Interaktionen im Bereich der Futtereinrichtungen bei beiden Fütterungssystemen gering. Die agonistischen Verhaltensweisen wurden zusätzlich noch von der Heumenge und dem Konstitutionstyp beeinfl usst. Der Betrieb erwies sich als maßgeblicher Einfl ussfaktor. Als Resümee ergibt sich, dass bei ordnungsgemäßer Gruppenhaltung mit fachgerechtem Management beide Fütterungssysteme für Pferde im Offenlaufstall geeignet sind. [The threatening and avoiding behaviour of 270 horses living in run-out sheds was observed at 10 stables with feeding stalls and at 11 stables with automatic feeding systems for hay and concentrates. Every group of horses was observed on five succeeding days visually and immediately for 6 sessions, each of 4 hours. These 6 slices form together 24 hours, a complete day. Altogether, 6297 agonistic behaviour patterns were registered in front of, inside and behind the feeding stations (avoiding behaviour 40.6 %, edging out of others 12.8 %, Auseinandersetzungen an automatischer Abruffütterung und Fressständen KTBL-Schrift 471 79 biting/rear leg kicking/charging 12.7 % und threatening/biting threats/rear leg kicking threats 33.9 %). 22.5 % of these types of behaviour were recorded in the feeding stations, 77.5 % together in front and behind of these. In the stables with feeding stalls there were 31 % of the observed threatening gestures inside the feeding stations, in the stables with automatic feeders only 21 %. The individual farm showed signifi cant infl uence on the modes of agonistic behaviour in front and behind the feeding facilities. Threatening gestures happen more often in the waiting area of automatic feeders than in that of feeding stalls. On the other hand horses in computer controlled systems will be less disturbed at eating. All together the number of negative interactions in the feeding area at both feeding systems was relatively low. In addition the agonistic behaviour was infl uenced by the quantity of hay and the constitutional typ of the horses. Because of the management of the individual stable exercises the most substantial infl uence on the behaviour of the horses, it can be said, that, correct group keeping with professional management provided, both feeding systems are suitable for horses in run-in sheds.] |

| Abstract | The oxidation-reduction reaction of horse heart cytochrome c and cytochrome c (552, Thermus thermophilus), which is highly thermoresistant, was studied by temperature-jump method. Ferrohexacyanide was used as reductant. (Formula: see text.) Thermodynamic and activation parameters of the reaction obtained for both cytochromes were compared with each other. The results of this showed that (1) the redox potential of cytochrome c-552, + 0.19 V, is markedly less than that of horse heart cytochrome c. (2) deltaHox of cytochrome c-552 is considerably lower than that of horse heart cytochrome c. (3) deltaSox and deltaSred of cytochrome c-552 are more negative than those of horse heart cytochrome c. (4) kred of cytochrome c-552 is much lower than that of horse heart cytochrome c at room temperature. | ||||

| Abstract | Indirect reciprocity1, 2, 3, 4, 5 is a key mechanism for the evolution of human cooperation. Our behaviour towards other people depends not only on what they have done to us but also on what they have done to others. Indirect reciprocity works through reputation5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17. The standard model of indirect reciprocity offers a binary choice: people can either cooperate or defect. Cooperation implies a cost for the donor and a benefit for the recipient. Defection has no cost and yields no benefit. Currently there is considerable interest in studying the effect of costly (or altruistic) punishment on human behaviour18, 19, 20, 21, 22, 23, 24, 25. Punishment implies a cost for the punished person. Costly punishment means that the punisher also pays a cost. It has been suggested that costly punishment between individuals can promote cooperation. Here we study the role of costly punishment in an explicit model of indirect reciprocity. We analyse all social norms, which depend on the action of the donor and the reputation of the recipient. We allow errors in assigning reputation and study gossip as a mechanism for establishing coherence. We characterize all strategies that allow the evolutionary stability of cooperation. Some of those strategies use costly punishment; others do not. We find that punishment strategies typically reduce the average payoff of the population. Consequently, there is only a small parameter region where costly punishment leads to an efficient equilibrium. In most cases the population does better by not using costly punishment. The efficient strategy for indirect reciprocity is to withhold help for defectors rather than punishing them. | ||||

| Abstract | Humans regularly produce new utterances that are understood by other members of the same language community. Linguistic theories account for this ability through the use of syntactic rules (or generative grammars) that describe the acceptable structure of utterances. The recursive, hierarchical embedding of language units (for example, words or phrases within shorter sentences) that is part of the ability to construct new utterances minimally requires a 'context-free' grammar that is more complex than the 'finite-state' grammars thought sufficient to specify the structure of all non-human communication signals. Recent hypotheses make the central claim that the capacity for syntactic recursion forms the computational core of a uniquely human language faculty. Here we show that European starlings (Sturnus vulgaris) accurately recognize acoustic patterns defined by a recursive, self-embedding, context-free grammar. They are also able to classify new patterns defined by the grammar and reliably exclude agrammatical patterns. Thus, the capacity to classify sequences from recursive, centre-embedded grammars is not uniquely human. This finding opens a new range of complex syntactic processing mechanisms to physiological investigation. | ||||

| Abstract | Networks of coupled dynamical systems have been used to model biological oscillators Josephson junction arrays excitable media, neural networks spatial games11, genetic control networks12 and many other self-organizing systems. Ordinarily, the connection topology is assumed to be either completely regular or completely random. But many biological, technological and social networks lie somewhere between these two extremes. Here we explore simple models of networks that can be tuned through this middle ground: regular networks 'rewired' to introduce increasing amounts of disorder. We find that these systems can be highly clustered, like regular lattices, yet have small characteristic path lengths, like random graphs. We call them 'small-world' networks, by analogy with the small-world phenomenon (popularly known as six degrees of separation). The neural network of the worm Caenorhabditis elegans, the power grid of the western United States, and the collaboration graph of film actors are shown to be small-world networks. Models of dynamical systems with small-world coupling display enhanced signal-propagation speed, computational power, and synchronizability. In particular, infectious diseases spread more easily in small-world networks than in regular lattices. | ||||

| Abstract | Although positive reciprocity (reciprocal altruism) has been a focus of interest in evolutionary biology, negative reciprocity (retaliatory infliction of fitness reduction) has been largely ignored. In social animals, retaliatory aggression is common, individuals often punish other group members that infringe their interests, and punishment can cause subordinates to desist from behaviour likely to reduce the fitness of dominant animals. Punishing strategies are used to establish and maintain dominance relationships, to discourage parasites and cheats, to discipline offspring or prospective sexual partners and to maintain cooperative behaviour. | ||||

| 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. | ||||
