Title Predicting the dynamics of animal behaviour in field populations Type Journal Article
Year 2007 Publication Animal Behaviour. Abbreviated Journal Anim. Behav.
Volume 74 Issue 1 Pages 103-110
Keywords colony occupancy; differential equation; dynamic modelling; glaucous-winged gull; habitat ecology; Larus glaucescens; mathematical modelling; sleep; territory attendance
Abstract Many species show considerable variation in behaviour among individuals. We show that some behaviours are largely deterministic and predictable with mathematical models. We propose a general differential equation model of behaviour in field populations and use the methodology to explain and predict the dynamics of sleep and colony attendance in seabirds as a function of environmental factors. Our model explained over half the variability in the data to which it was fitted, and it predicted the dynamics of an independent data set. Differential equation models may provide new approaches to the study of behaviour in animals and humans.

Title A demonstration of observational learning in rats using a bidirectional control Type Journal Article
Year 1990 Publication Quarterly Journal of Experimental Psychology Section B: Comparative and Physiological Psychology Abbreviated Journal Q J Exp Psychol B
Volume 42 Issue 1 Pages 59-71
Keywords appetite; attention; imitation; problem solving; psychomotor performance; Appetitive Behavior; Attention; Imitative Behavior; Problem Solving; Psychomotor Performance
Abstract Hungry rats observed a conspecific demonstrator pushing a single manipulandum, a joystick, to the right or to the left for food reward and were then allowed access to the joystick from a different orientation. The effects of right-pushing vs left-pushing observation experience on (1) response acquisition, (2) reversal of a left-right discrimination, and (3) responding in extinction, were examined. Rats that had observed left-pushing made more left responses during acquisition than rats that had observed right-pushing, and rats that had observed demonstrators pushing in the direction that had previously been reinforced took longer to reach criterion reversal and made more responses in extinction than rats that had observed demonstrators pushing in the opposite direction to that previously reinforced. These results provide evidence that rats are capable of learning a response, or a response-reinforcer contingency, through conspecific observation.

Title Humans and Horses 300.000 years ago – An approach to public presentation in the research and experience centre Schöningen spears Type Conference Article

Volume in press Issue Pages
Keywords
Abstract We are introducing a new research and experience center located near the stripmine of Schöningen in western Germany, one of the most important archaeological sites in the world, which is scheduled to open its doors in 2013. The 1995 discovery of wooden hunting spears (Thieme 1997) in conjunction with the remains of hunted and butchered horses (Equus mosbachensis) contributed significantly to change the scientific view of early European Hominids being “marginal scavengers” (Binford 1981, Gamble 1987) to skilled hunters. The remains of at least 19 horses were unearthed along a former lakeshore. Initial publications demonstrate early hominid butchery systematics designed to achieve a thorough acquisition of horse products (Voormolen 2008). In order to get a better understanding of the possible hunting scenario (Thieme 2007) knowledge of wild horse behaviour is of primary interest. The exhibit section of the new center is developed to present an experience oriented concept. Access to artefacts, such as the over 300.000 year old spears, is correlated with exhibits concerning Pleistocene horse morphology, group structure and behaviour of modern day wild horses in order to draw a vivid image of the past

Title Folding units govern the cytochrome c alkaline transition Type Journal Article
Year 2003 Publication Journal of Molecular Biology Abbreviated Journal J Mol Biol
Volume 331 Issue 1 Pages 37-43
Keywords Animals; Cytochrome c Group/*chemistry; Horses; Hydrogen/chemistry; Hydrogen-Ion Concentration; Kinetics; Models, Molecular; *Protein Folding; Protein Structure, Tertiary; Spectrum Analysis; Titrimetry
Abstract The alkaline transition of cytochrome c is a model for protein structural switching in which the normal heme ligand is replaced by another group. Stopped flow data following a jump to high pH detect two slow kinetic phases, suggesting two rate-limiting structure changes. Results described here indicate that these events are controlled by the same structural unfolding reactions that account for the first two steps in the reversible unfolding pathway of cytochrome c. These and other results show that the cooperative folding-unfolding behavior of protein foldons can account for a variety of functional activities in addition to determining folding pathways.

Title Preference for spatial cues in a non-storing songbird species Type Journal Article
Year 2005 Publication Animal Cognition Abbreviated Journal Anim. Cogn.
Volume 8 Issue 3 Pages 211-214
Keywords Animals; Association Learning/*physiology; *Cues; Feeding Behavior/physiology; Female; Male; Memory/*physiology; Sex Factors; Songbirds/*physiology; Space Perception/*physiology; Spatial Behavior/*physiology
Abstract Male mammals typically outperform their conspecific females on spatial tasks. A sex difference in cues used to solve the task could underlie this performance difference as spatial ability is reliant on appropriate cue use. Although comparative studies of memory in food-storing and non-storing birds have examined species differences in cue preference, few studies have investigated differences in cue use within a species. In this study, we used a one-trial associative food-finding task to test for sex differences in cue use in the great tit, Parus major. Birds were trained to locate a food reward hidden in a well covered by a coloured cloth. To determine whether the colour of the cloth or the location of the well was learned during training, the birds were presented with three wells in the test phase: one in the original location, but covered by a cloth of a novel colour, a second in a new location covered with the original cloth and a third in a new location covered by a differently coloured cloth. Both sexes preferentially visited the well in the training location rather than either alternative. As great tits prefer colour cues over spatial cues in one-trial associative conditioning tasks, cue preference appears to be related to the task type rather than being species dependent.

Title Influence of an active stable system on the behavior and body condition of Icelandic horses Type Journal Article
Year 2012 Publication animal Abbreviated Journal
Volume 6 Issue 10 Pages 1684-1693
Keywords activity, automatic feeding system, behavior, body condition score, Icelandic horse
Abstract Horses are often stabled in individual boxes, a method that does not meet their natural needs and may cause psychical and

musculoskeletal diseases. This problem is particularly evident in Iceland, where horses often spend the long winter periods in cramped

boxes. The aim of this study was to analyze the suitability of a group housing system in Iceland, but the results are also applicable to

horses of other regions. Eight Icelandic horses were observed in an active stable system, and their behavior and time budget were

recorded. Movement and lying behavior were studied with ALT (Activity, Lying, Temperature detection) pedometers. The effect of an

automatic concentrate feeding station (CFS) on the horses’ behavior was examined. In the first period of investigation, the horses

were fed concentrates manually, and in the second period, they were fed with the CFS. Additional behavioral observations and a

determination of social hierarchy occurred directly or by video surveillance. The physical condition of the horses was recorded by body

weight (BW) measurement and body condition scoring (BCS). The results showed a significant increase between the first and second

trial periods in both the activity (P,0.001) and the lying time (P50.003) of the horses with use of the CFS. However, there was no

significant change in BW during the first period without the CFS (P50.884) or during the second period with the CFS (P50.540).

The BCS of the horses was constant at a very good level during both trial periods, and the horses showed a low level of aggression, a

firm social hierarchy and behavioral synchronization. This study concludes that group housing according to the active stable principle is

a welfare-friendly option for keeping horses and is a suitable alternative to conventional individual boxes.

Title Einfluss des Haltungssystems auf die Bewegungsaktivität und Stressbelastung bei Pferden in Auslaufhaltungssystemen Type Journal Article
Year 2009 Publication Landbauforschung – vTI Agriculture and Forestry Research Abbreviated Journal
Volume 2 Issue 59 Pages 105-112
Keywords Bewegung, Cortisol, Herzfrequenzvariabilität (HFV), Pferd, Verhalten [movement, cortisol, heart rate variability (HRV), horse, behaviour]
Abstract Frühere Untersuchungen haben gezeigt, dass die tägliche Bewegung für die Gesunderhaltung der Pferde notwendig ist. Inwieweit sich jedoch unterschiedliche Bewegungsangebote auf das Stress-und Bewegungsverhalten von Pferden in einer Gruppen-Auslaufhaltung auswirken und ob der Bewegungsbedarf der Pferde durch eine Auslaufhaltung ohne zusätzliche Bewegung gedeckt werden kann, ist der Literatur bisher nicht zu entnehmen. Daher sollte in der nachfolgend beschriebenen Untersuchung der Frage nachgegangen werden, welche Auswirkungen verschiedene Bewegungsangebote auf die Bewegungsaktivität von Pferden in Gruppen-Auslaufhaltungen haben und ob diese das Wohlbefinden der Tiere beeinflussen. Letzteres wurde durch Messung der Herzfrequenzvariabilität und Bestimmung von Cortisolmetaboliten im Pferdekot erfasst und die Bewegungsaktivität der Pferde wurde mit ALT-Pedometern bestimmt.

Verglichen wurden eine Einzel-und Gruppenhaltung mit jeweils angrenzendem Auslauf, aber ohne eine zusätzliche Bewegung der Pferde außerhalb des Stalls. In drei weiteren Varianten der Gruppenhaltung bekamen die Pferde täglichen Auslauf auf einer unbegrünten Koppel, auf einer Weide oder durch gezielte Bewegung in einer Führanlage. Die Bewegungsaktivität konnte durch die zusätzliche Bewegung in Form von Weide oder Führanlage signifikant gesteigert werden.

Ein zusätzliches Bewegungsangebot führte bei den Pferden zu einer Abnahme der Stressbelastung und sollte auch den Pferden ermöglicht werden, die in einer Gruppenhaltung gehalten werden, um ihre physische und psychische Gesundheit zu erhalten.

[Former studies confirm the necessity of daily movement for the health of a horse. But so far no description could be found in the literature how different movement offerings impact the stress and movement behaviour of horses in group husbandries with close-by discharge. The same holds true for the question whether a discharge husbandry system can meet the movement requirements of horses if there isn&#65533;t any additional movement possibility. The aim of the present study was to examine different movement offerings, their effects on the movement activities of horses in a group horse husbandry with close-by discharge and the impact of the movement on the wellbeing of the animals.

The heart rate variability and the concentration of the cortisol metabolites in the horse excrement were analyzed for detecting the wellbeing of the horses. Additionally ALT-Pedometers were used for determining the movement activity.

A single and a group husbandry system, each with closeby discharge, were compared when horses had no additional movement outside the stable. In three further variants the group husbandry was supplemented with daily time on a non-grassy pasture land, a pasture or in a horse walker. Pasture or horse walker increased movement activity significantly. Nevertheless an additional movement offering resulted in a lower stress load of the horses and should also be allowed to horses in group husbandry systems to ensure the horse&#65533;s physical and mental health.]

Title Bewegungsaktivität und Stressbelastung bei Pferden in Auslaufhaltungssystemen mit verschiedenen Bewegungsangeboten Type Manuscript
Year 2008 Publication Dissertation Abbreviated Journal
Volume Issue Pages
Keywords
Abstract Pferdehaltungssysteme mit angrenzenden Ausläufen gelten als eine sehr tiergerechte

Haltungsform, da sie den Tieren eine gewisse Bewegungsmöglichkeit

bieten. Ziel der vorliegenden Untersuchung war es, zu erfassen, ob der angrenzende

Auslauf selbst einen ausreichenden Anreiz zur Bewegung darstellt und wie sich verschiedene

Bewegungs- und Platzangebote auf die Bewegungsaktivität von Pferden

in einer Gruppen-Auslaufhaltung auswirken. Zudem wurde ermittelt, welche Auswirkung

die Bewegungsform bzw. –intensität auf das Wohlbefinden der Tiere hat.

Der Großteil der in Deutschland gehaltenen Pferde verbringt die meiste Zeit des

Tages im Stall, obwohl mittlerweile bekannt ist, dass Pferde unter natürlichen

Haltungsbedingungen 12 bis 16 Stunden des Tages in Bewegung verbringen. Der

Optimierung der Stallhaltungssysteme gilt daher ein besonderes Interesse.

Zu diesem Zweck wurden von September 2004 bis Oktober 2005 Versuche mit 24

Warmblutstuten im Alter von 1½ bis 3½ Jahren in Einzel- und Gruppen-

Auslaufhaltungssystemen durchgeführt. Jeweils sechs Pferde bildeten eine Versuchsgruppe.

In jeder Gruppe fanden fünf Varianten von einer ca. dreiwöchigen

Dauer statt. Die Gruppenhaltung wurde dabei durch drei unterschiedliche Zusatzbewegungsangebote

(2 Std. Weide / Tag, 2 Std. unbegrünte Koppel / Tag, 1 Std. Freilauf-

Führanlage / Tag) ergänzt. In der Einzel-Auslaufhaltung (Box mit 45 m²-großem

angrenzenden Auslauf) und in einer Versuchsvariante der Gruppenhaltung bekamen

die Pferde hingegen keine zusätzliche Bewegung außerhalb des Stallhaltungssystems

angeboten. Das Gruppenhaltungssystem selbst war durch die räumliche

Trennung der Funktionsbereiche (Liegen, Fressen, Trinken, Bewegen) gekennzeichnet

und der angrenzende Auslauf war 270 m² groß. In einer zusätzlichen Versuchsphase

fand in der Gruppenhaltung eine Erweiterung des permanent zugänglichen

Auslaufs auf insg. 540 m² statt.

Die Bewegungsaktivität wurde mit Pedometern erfasst, die an jeweils einem Hinterbein

der Pferde befestigt wurden und ergänzend fand eine Analyse von Videoaufzeichnungen

statt. Zur Beurteilung der Stressbelastung fanden Messungen der Herz192

Zusammenfassung

frequenzvariabilität (Parameter HF und SD2) und der fäkalen Cortisolmetabolitenkonzentration

statt.

Die Auswertung des Bewegungsverhaltens ergab, dass eine zusätzliche zweistündige

freie Bewegung der Pferdegruppe auf einer Weide zu einer deutlichen

Steigerung der durchschnittlichen Bewegungsaktivität (149,6 Min. / Tag) führt,

ebenso wie eine einstündige Bewegung in einer Führanlage (173,0 Min. / Tag). Eine

unbegrünte Koppel regte die Pferde der Gruppenhaltung hingegen nicht zu vermehrter

Bewegung an (131,6 Min. / Tag), sondern bewirkte z. T. sogar eine Abnahme

der Bewegungsaktivität. In der Gruppen-Auslaufhaltung ohne zusätzliches Bewegungsangebot

war die Bewegungsaktivität ebenfalls gering (125,8 Min / Tag) und

während der Einzel-Auslaufhaltung ohne Zusatzbewegung zeigten die Pferde die

geringste Bewegungsaktivität (102,3 Min. / Tag).

Bei der alleinigen Analyse der Bewegungszeit im Stallhaltungssystem war kein signifikanter

Einfluss der zusätzlichen Bewegung außerhalb des Stallsystems auf die

übrige Fortbewegung feststellbar.

Auch eine Vergrößerung des an den Stall angrenzenden Auslaufs im Gruppenhaltungssystem

hatte keinen steigernden Einfluss auf das Bewegungsverhalten der

Pferde.

Die Stressbelastung der Pferde war in den Varianten der Gruppenhaltung mit zweistündigem

Weidegang (SD2: 82,9 ms; Cortisolmetaboliten: 29,0 nmol / kg Kot) sowie

der einstündigen Bewegung in einer Freilauf-Führanlage (SD2: 99,2 ms; Cortisolmetaboliten:

27,7 nmol / kg Kot) am geringsten. Die Untersuchungen zeigten eine

Stresszunahme in der Gruppenhaltung mit zweistündigem Auslauf auf einer unbegrünten

Koppel ohne Futterangebot (SD2: 101,3 ms; Cortisolmetaboliten:

39,6 nmol / kg Kot) sowie in der Variante der Gruppenhaltung ohne zusätzliches Bewegungsangebot

(SD2: 113,3 ms; Cortisolmetaboliten: 38,4 nmol / kg Kot). Dem

Mittelwert der Gruppe nach zu folgern hatten die Pferde während der Einzelhaltung

ohne Zusatzbewegung eine sehr große Stressbelastung (SD2: 123,8 ms; Cortisolmetaboliten:

37,5 nmol / kg Kot). Ein Vergleich der Gruppen- und Einzelhaltung hinsichtlich

der Herzfrequenzvariabilität hat jedoch gezeigt, dass insg. 70 % der Pferde

während der Haltung in einer Gruppe weniger Stress empfinden. Es gab aber auch

Zusammenfassung 193

Pferde (30 %), die in der Einzelhaltung eine abnehmende Stressbelastung zeigten,

wobei hier der Einfluss der Rangordnung eine entscheidende Rolle zu spielen

scheint.

Durch die Auswertung mehrerer Messparameter (sowohl für Stress- als auch für Bewegungsverhalten)

werden gleichgerichtete Tendenzen bei den Versuchsvarianten

deutlich, allerdings ist eine eindeutige Gewichtung der Parameter nicht möglich.

Somit ist die methodische Vorgehensweise dieser Untersuchung sehr positiv und als

notwendig anzusehen, da die Messdaten auch immer gewissen Schwankungen

durch externe Einflüsse unterliegen.

Allgemein ist festzuhalten, dass Auslaufhaltungssysteme zwar eine gewisse

Anregung zur Bewegung bieten, aber mit maximal vier Stunden (insg. 62 – 248 Min.)

Bewegung pro Tag war der tägliche Anteil an Bewegung sehr viel geringer als

beispielsweise bei Pferden in freier Wildbahn oder ganzjähriger Weidehaltung. Somit

deckt ein Auslaufhaltungssystem trotz getrennter Funktionsbereiche und eines

großen Auslaufs nicht den Bewegungsbedarf der Pferde, wenn keine zusätzlichen

Bewegungsanreize und –möglichkeiten angeboten werden.

Eine zusätzliche Bewegung von Pferden ist nicht nur zur Gesunderhaltung des

Bewegungsapparates und der Körperfunktionen notwendig, sondern auch um das

Wohlbefinden und die Ausgeglichenheit der Pferde zu steigern.

[Horse husbandry systems with close-by discharge are considered to be a very livestock-

friendly housing form, as they offer a certain movement opportunity for the

animals. The aim of the present study was to examine how different movement and

space offerings affect the movement activities of horses in a group horse husbandry

with close-by discharge, and whether the discharge provides itself an adequate

incentive for movement. The impact that the form or rather intensity of movement has

on the wellbeing of the animals was also established.

Most of the horses held in Germany spend most of the day in the stable, although it is

meanwhile known that horses under natural housing conditions are 12 to 16 hours of

the day in motion. Therefore the improvement of stable housing systems applies a

special interest.

For this purpose, 24 warmblood mares, aged from 1½ to 3½ years, were studied in

single and group discharge husbandry systems from September 2004 until October

2005. Six horses formed an experimental group. In every group five variants of approximately

three weeks were proceeded. Thereby the group husbandry was supplemented

with three different additional movement opportunities (2 h pasture / day,

2 h non-grassy pasture land / day, 1 h free range horse walker / day). In the single

discharge husbandry (single box with 45 sq. m-large close-by discharge) and in one

experimental variant of the group husbandry got the horses, however, offered no additional

movement outside the husbandry system. The group husbandry system itself

was marked by the spatial division of the functional areas (lying, eating, drinking,

moving) and the close-by discharge measured 270 sq. m. In an additional phase of

the study, and expansion of the permanently accessible close-by discharge to

540 sq. m was found.

The movement activity was documented with pedometers attached respectively to

one hind leg of the horse and a supplementary analysis of video documentation. To

evaluate the stress exposure measurements of heart frequency variability (parameters

HF and SD2) and of the faecal cortisol metabolite concentration were performed.

Summary 195

The interpretation of the movement behaviour showed that additional two hours of

free movement on a pasture led to a significant increase in the average movement

activity (149.6 min / day), as well as one hour movement in a horsewalker did

(173.0 min / day). The non-grassy pasture land, however, didn’t inspire the horses of

the group husbandry to increased movement (131.6 min / day), but sometimes even

caused a decrease in movement activity. In the group discharge husbandry without

additional movement opportunities the movement activity was also low

(125.8 min / day), and during the single discharge husbandry without additional

movement the horses showed the least movement activity (102.3 min / day).

In analysing only the movement time in the stable system was no significant impact

of the additional movement outside the housing system to the rest of locomotion

ascertainable.

As well an expansion of the close-by stable discharge in the group husbandry system

had no increasing influence on the movement behaviour of the horses.

The stress exposure of the horses was least in the variations of group husbandry

with two hours on a pasture (SD2: 82.9 ms; cortisol metabolites: 29.0 nmol / kg faeces)

as well as one hour of movement in a free range horse walker (SD2: 99.2 ms;

cortisol metabolites: 27.7 nmol / kg faeces). The studies showed a rise in stress in

group husbandry with two hours of movement on a non-grassy pasture land without

feeding opportunity (SD2: 101.3 ms; cortisol metabolites: 39.6 nmol / kg faeces) as

well as in the variation of the group husbandry without additional movement offerings

(SD2: 113.3 ms; cortisol metabolites: 38.4 nmol / kg faeces). Judging from the mean

of the group the horses had a very high stress exposure in the variation of the single

husbandry without additional movement offerings (SD2: 123.8 ms; cortisol metabolites:

37.5 nmol / kg faeces). But a comparison of the group and single husbandry in

terms of the heart frequency variability showed that alltogether 70 % of the horses

experienced less stress if hold in a group. However, some horses (30 %) showed

reducing stress in the single husbandry, whereas here the influence of social hierarchy

seems to play a decisive role.

196 Summary

In consequence of the examination of several measuring parameters (both for stressand

for movement behaviour) parallel aligned tendencies become apparent in the

experimental variants, however, is a unique weighting of the parameters not possible.

Thus, the methodological approach of this study is to be regarde as very positive and

necessary, since the data always vary with some fluctuations by external influences.

In general it can be established that discharge husbandry systems offer some incentive

for the horse to move, but with a maximum of four hours (overall 62 – 248 min) of

movement per day, the daily proportion of movement was much less than, for example,

in the case of wild horses or year-round pasture keeping. Thus, if no additional

movement incentives and possibilities are offered, the discharge husbandry system

doesn’t cover the movement needs of the horse despite separate functional areas

and a large outside discharge.

Additional movement is not only necessary to keep the musculoskeletal system and

bodily functions of the horse healthy, but also to ensure the horse’s well being and

mental balance.]
