Abstract |
The scientific investigation of the basics of the inherited riding teachings assists in conserving its values. Riding instructors should be able to teach not only “how” but also “why”.
The classic European riding teachings that have developed across the centuries are based on perceptions that have their roots in natural phenomena. They are being mirrored, for instance, in the aids to stimulate the change from one gait to the next.
The movements of the horse's trunk and back provide timers for horse-friendly, sensitive aids that create attentive, diligent and happily cooperating horses. |

Abstract |
Zusammenfassung
Wissenschaftliches Erfassen von Grundlagen der ererbten Reitlehre hilft, deren Werte zu bewahren. Und Reiten Lehrende dürfen nicht nur das “Wie”, sie sollten auch das “Weshalb” vermitteln können.
Die Grundlagen der in Jahrhunderten entstandenen klassischen europäischen Reitlehre beruhen auf der Natur abgelauschten Erkenntnissen. Sie spiegeln sich u. a. in den Hilfen für Übergänge aus einer Gangart in eine andere.
Die Bewegungen von Pferderumpf und -rücken liefern den Zeitgeber für jene pferdgerechte, feinfühlige Hilfengebung, die aufmerksam, fleißig und freudig mitarbeitende Pferde schafft. |

cultured riding – horse-rider-harmony – sensitive-invisible aids – saving the backs of both horse and rider |
|
| |
Abstract |
From the base to the top of the sport horses are being coerced into “obedience” or the performance of exercises by force. Campaigns against the “Rollkur” or “Hyperflexion” fill the media. However the root of evil lies a lot deeper. The base of cultured riding in high harmony between horse and rider are sensitive, almost invisible aids which are being timed by the movements of the horse's back and trunk. Anchoring the knowledge of this interrelation in rider's minds has to this day been unsuccessful. |

Abstract |
The horse's movement cycles while lying down, rolling and jumping up again as well as the necessary use of the horse's head and neck as a balancing rod will be explained with the help of photographic sequences. The reasons for lying down and rolling as well as the utilization of information on the connected motion sequences will be touched upon. |

Abstract |
n many animal systems agonistic interactions may be rare or not overt, particularly where such interactions are costly or of high risk as is common for large mammals. We present a technique developed specifically for resolving an optimized dominance order of individuals in systems with transitive (i.e. linear) dominance relationships, but where not all relationships are known. Our method augments the widely used I&SI method (de Vries, 1998) with an interpolation function for resolving the relative ranks of individuals with unknown relationships. Our method offers several advantages over other dominance methods by enabling the incorporation of any proportion of unknown relationships, resolving a unique solution to any dominance matrix, and calculating cardinal dominance strengths for each individual. As such, this method enables novel insight into difficult to study behavioural systems. |

Abstract |
In the analysis of social dominance in groups of animals, linearity has been used by many researchers as the main structural characteristic of a dominance hierarchy. In this paper we propose, alongside linearity, a quantitative measure for another property of a dominance hierarchy, namely its steepness. Steepness of a hierarchy is defined here as the absolute slope of the straight line fitted to the normalized David's scores (calculated on the basis of a dyadic dominance index corrected for chance) plotted against the subjects' ranks. This correction for chance is an improvement of an earlier proposal by de Vries (appendix 2 in de Vries, Animal Behaviour, 1998, 55, 827-843). In addition, we present a randomization procedure for determining the statistical significance of a hierarchy's steepness, which can be used to test the observed steepness against the steepness expected under the null hypothesis of random win chances for all pairs of individuals. Whereas linearity depends on the number of established binary dominance relationships and the degree of transitivity in these relationships, steepness measures the degree to which individuals differ from each other in winning dominance encounters. Linearity and steepness are complementary measures to characterize a dominance hierarchy. |

Abstract |
In many gregarious species, including ducks and geese, being dominant provides more benefits than costs, because dominants have better access to resources essential for survival or reproduction. In geese, being in better body condition during migration towards the breeding grounds positively influences reproductive success. However, underlying proximate mechanisms linking prebreeding body condition on the wintering grounds to breeding success remain poorly understood. We investigated social dominance correlates and family status, in three consecutive winters, in a free-ranging, migrating, dark-bellied brent goose population. Families with juveniles dominated pairs, and pairs dominated singletons. Dominance rank did not increase with the number of juveniles per family. Males were dominant over females. Social dominance and reproductive status for a given winter were significantly correlated with body mass, body size and body condition during the previous winter, suggesting that body condition in winter also affects subsequent breeding success and hence also dominance. Levels of testosterone and triiodothyronine were not correlated with immediate or later dominance or reproductive status. We discuss the role of family status as a signal of social status in determining reproductive strategies. |

Abstract |
The dominance score (number of wins divided by the total number of interactions) is the most widely used procedure in field studies to rank individuals. Its reliability depends on the number of interactions on which it is calculated. However, most authors use it without any estimate of the associated error. We describe the precision associated with a dominance score estimate as a function of the number of interactions on which it is based, and hence provide a tool to plan field protocols and effort. The precision error decreases according to a power function with increasing number of interactions, but with more precision for extreme scores for any given number of interactions. We discuss the fact that the minimum number of interactions should be based on the precision associated with the 50% score, the least precise of all scores. We also emphasize the trade-off between recording effort and precision of the estimator, and give an example of our choice of 26 interactions for fieldwork on ducks and geese. When comparing individual ranks based on dominance scores with ranks given by the dominance matrix, we found a good correlation, with more mismatches around the middle of the hierarchy. This was consistent with the precision calculated with our model. We conclude that dominance score is a reliable tool, but conclusions must take into account the number of interactions on which the calculations are done. We also discuss the importance of initial assumptions and sources of bias in field studies. |

Abstract |
We review studies demonstrating the ability of some animals to understand the human pointing gesture. We present a 3-step analysis of the topic. (1) We compare and evaluate current experimental methods (2) We compare available experimental results on performance of different species and investigate the interaction of species differences and other independent variables (3) We evaluate how our present understanding of pointing comprehension answers questions about function, evolution and mechanisms. Recently, a number of different hypotheses have been put forward to account for the presence of this ability in some species and for the lack of such comprehension in others. In our view, there is no convincing evidence for the assumption that the competitive lifestyles of apes would inhibit the utilization of this human gesture. Similarly, domestication as a special evolutionary factor in the case of some species falls short in explaining high levels of pointing comprehension in some non-domestic species. We also disagree with the simplistic view of describing the phenomenon as a simple form of conditioning. We suggest that a more systematic comparative research is needed to understand the emerging communicative representational abilities in animals that provide the background for comprehending the human pointing gesture. |
