| Abstract | The authors report a novel approach to testing episodic-like memory for single events. Pigeons were trained in separate sessions to match the identity of a sample on a touch screen, to match its location, and to report on the length of the retention interval. When these 3 tasks were mixed randomly within sessions, birds were more than 80% correct on each task. However, performance on 2 different tests in succession after each sample was not consistent with an integrated memory for sample location, time, and identity. Experiment 2 tested binding of location and identity memories in 2 different ways. The results were again consistent with independent feature memories. Implications for tests of episodic-like memory are discussed. | ||||

| Abstract | We investigated the potential relationships between foraging strategies and relative brain and brain region volumes in predatory (animal-eating) echolocating bats. The species we considered represent the ancestral state for the order and approximately 70% of living bat species. The two dominant foraging strategies used by echolocating predatory bats are substrate-gleaning (taking prey from surfaces) and aerial hawking (taking airborne prey). We used species-specific behavioral, morphological, and ecological data to classify each of 59 predatory species as one of the following: (1) ground gleaning, (2) behaviorally flexible (i.e., known to both glean and hawk prey), (3) clutter tolerant aerial hawking, or (4) open-space aerial hawking. In analyses using both species level data and phylogenetically independent contrasts, relative brain size was larger in behaviorally flexible species. Further, relative neocortex volume was significantly reduced in bats that aerially hawk prey primarily in open spaces. Conversely, our foraging behavior index did not account for variability in hippocampus and inferior colliculus volume and we discuss these results in the context of past research. | ||||

| Title | Self-recognition in an Asian elephant | Type | Journal Article | ||
| Year | 2006 | Publication | Proceedings of the National Academy of Sciences of the United States of America | Abbreviated Journal | Proc. Natl. Acad. Sci. U.S.A. |

| Abstract | Considered an indicator of self-awareness, mirror self-recognition (MSR) has long seemed limited to humans and apes. In both phylogeny and human ontogeny, MSR is thought to correlate with higher forms of empathy and altruistic behavior. Apart from humans and apes, dolphins and elephants are also known for such capacities. After the recent discovery of MSR in dolphins (Tursiops truncatus), elephants thus were the next logical candidate species. We exposed three Asian elephants (Elephas maximus) to a large mirror to investigate their responses. Animals that possess MSR typically progress through four stages of behavior when facing a mirror: (i) social responses, (ii) physical inspection (e.g., looking behind the mirror), (iii) repetitive mirror-testing behavior, and (iv) realization of seeing themselves. Visible marks and invisible sham-marks were applied to the elephants' heads to test whether they would pass the litmus “mark test” for MSR in which an individual spontaneously uses a mirror to touch an otherwise imperceptible mark on its own body. Here, we report a successful MSR elephant study and report striking parallels in the progression of responses to mirrors among apes, dolphins, and elephants. These parallels suggest convergent cognitive evolution most likely related to complex sociality and cooperation. | ||||

| Keywords | Kultiviertes Reiten – Mensch-Pferd-Harmonie – feinfühlige, unsichtbare Hilfengebung – Schonen des Rückens von Reiter und Pferd | ||||
| Abstract | Von der Basis bis zum Spitzensport werden Pferde gewaltsam zum “Gehorsam” gebracht oder zur Ausführung von Übungen gezwungen. Aktionen gegen die “Rollkur” oder “Hyperflexion” füllen die Medien. Aber die Wurzel des Übels liegt viel tiefer. Die Grundlage kultivierten Reitens in hoher Harmonie zwischen Mensch und Pferd ist eine feinfühlige, nahezu unsichtbare Hilfengebung, für die Bewegungen des Pferderückens und des Pferderumpfes den Zeitgeber liefern. Das Wissen darum in der Reiterwelt zu verankern, ist noch immer nicht gelungen. | ||||

| 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. |

| Keywords | 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. | ||||

| Title | The Rider's Impacts and Their Timers – Example: Rider's Aids for Transitions Between Different Gaits. | Type | Journal Article | ||
| Year | 2006 | Publication | Tierärztliche Umschau | Abbreviated Journal | Tierärztl. Umschau |
| Volume | 10 | Issue | Pages | 515-532 | |
| Keywords | Animal-friendly rider-horse communication – signals for changing the footfall – knee-jerk impacts in the single “fitting” moment – singular timer for those – immediate “obedience” | ||||
| 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. |

| Title | A likely ranking interpolation for resolving dominance orders in systems with unknown relationships | Type | Journal Article | ||
| Year | 2006 | Publication | Behaviour | Abbreviated Journal | Behaviour |
| Volume | 143 | Issue | 7 | Pages | 909-930 |
| Keywords | DOMINANCE HIERARCHY; ALGORITH; SOCIAL AGONISTIC INTERACTIONS | ||||
| 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. | ||||
