Abstract | We present a self-organizing model of group formation in three-dimensional space, and use it to investigate the spatial dynamics of animal groups such as fish schools and bird flocks. We reveal the existence of major group-level behavioural transitions related to minor changes in individual-level interactions. Further, we present the first evidence for collective memory in such animal groups (where the previous history of group structure influences the collective behaviour exhibited as individual interactions change) during the transition of a group from one type of collective behaviour to another. The model is then used to show how differences among individuals influence group structure, and how individuals employing simple, local rules of thumb, can accurately change their spatial position within a group (e.g. to move to the centre, the front, or the periphery) in the absence of information on their current position within the group as a whole. These results are considered in the context of the evolution and ecological importance of animal groups. | ||||

Abstract | Interest in the problem of method biases has a long history in the behavioral sciences. Despite this, a comprehensive summary of the potential sources of method biases and how to control for them does not exist. Therefore, the purpose of this article is to examine the extent to which method biases influence behavioral research results, identify potential sources of method biases, discuss the cognitive processes through which method biases influence responses to measures, evaluate the many different procedural and statistical techniques that can be used to control method biases, and provide recommendations for how to select appropriate procedural and statistical remedies for different types of research settings.

Title | Comparative Vertebrate Lateralization | Type | Book Whole | ||
Year | 2002 | Publication | Abbreviated Journal | ||
Volume | Issue | Pages | |||
Keywords | |||||
Abstract | No longer viewed as a characteristic unique to humans, brain lateralization is considered a key property of most, if not all, vertebrates. This field of study provides a firm basis from which to examine a number of important issues in the study of brain and behaviour. This book takes a comparative and integrative approach to lateralization in a wide range of vertebrate species, including humans. It highlights model systems that have proved invaluable in elucidating the function, causes, development, and evolution of lateralization. The book is arranged in four parts, beginning with the evolution of lateralization, moving to its development, to its cognitive dimensions, and finally to its role in memory. Experts in lateralization in lower vertebrates, birds, non-primate mammals, and primates have contributed chapters in which they discuss their own research and consider its implications to humans. The book is suitable for researchers, graduates and advanced undergraduates in psychology, neuroscience and the behavioral sciences. - Unique in its truly comparative approach, covering fish, amphibians, birds, and mammals (including primates and humans) – World-class editors and contributors – Very broad coverage of both theoretical and technical aspects of laterality, including evolution, development, behaviour, and memory Contents Preface; Introduction; Part I.

Title | Comparing Networks Across Space and Time, Size and Species | Type | Journal Article | ||
Year | 2002 | Publication | Sociological Methodology | Abbreviated Journal | Socio Meth |
Volume | 32 | Issue | 1 | Pages | 267-299 |
Keywords | |||||
Abstract | We describe and illustrate methodology for comparing networks from diverse settings. Our empirical base consists of 42 networks from four kinds of species (humans, nonhuman primates, nonprimate mammals, and birds) and covering distinct types of relations such as influence, grooming, and agonistic encounters. The general problem is to determine whether networks are similarly structured despite their surface differences. The methodology we propose is generally applicable to the characterization and comparison of network2013level social structures across multiple settings, such as different organizations, communities, or social groups, and to the examination of sources of variability in network structure. We first fit a p* model (Wasserman and Pattison 1996) to each network to obtain estimates for effects of six structural properties on the probability of the graph. We then calculate predicted tie probabilities for each network, using both its own parameter estimates and the estimates from every other network in the collection. Comparison is based on the similarity between sets of predicted tie probabilities. We then use correspondence analysis to represent the similarities among all 42 networks and interpret the resulting configuration using information about the species and relations involved. Results show that similarities among the networks are due more to the kind of relation than to the kind of animal. | ||||

Title | Conditioning taste aversions to locoweed (Oxytropis sericea) in horses | Type | Journal Article | ||
Year | 2002 | Publication | Journal of Animal Science | Abbreviated Journal | J. Anim. Sci. |
Volume | 80 | Issue | 1 | Pages | 79-83 |
Keywords | |||||
Abstract | Locoweed (Oxytropis sericea) is a serious poisoning problem for horses grazing on infested rangelands in the western United States. Our objectives were to determine 1) whether lithium chloride or apomorphine would condition aversions to palatable foods, and at what doses, and 2) whether horses could be averted to fresh locoweed in a pen and grazing situation. Apomorphine was not an acceptable aversive agent because at the dose required to condition an aversion (> or = 0.17 mg/kg BW), apomorphine induced unacceptable behavioral effects. Lithium chloride given via stomach tube at 190 mg/kg BW conditioned strong and persistent aversions to palatable feeds with minor signs of distress. Pen and grazing tests were conducted in Colorado to determine if horses could be averted to fresh locoweed. Pen tests indicated that most horses (5/6) were completely averted from locoweed. Treated horses ate 34 g of fresh locoweed compared to 135 g for controls (P < 0.01) during three pen tests when offered 150 g per test. One horse (T) in the treatment group ate locoweed each time it was offered in the pen, but ate no locoweed while grazing. In the grazing trial, control horses averaged 8.6% of bites of locoweed (P < 0.01) during the grazing portion of the study, whereas treated horses averaged <0.5%. One treated horse (S) accounted for all consumption; he consumed 15% of his bites as locoweed in a grazing bout on d 2 of the field study. Thereafter, he was dosed a second time with lithium chloride and ate no locoweed in the subsequent 5 d. Three of six horses required two pairings of lithium chloride with fresh locoweed to condition a complete aversion. The results of this study indicate that horses can be averted from locoweed using lithium chloride as an aversive agent, and this may provide a management tool to reduce the risk of intoxication for horses grazing locoweed-infested rangeland. | ||||

Abstract | Chimpanzee research plays a central role in the discussions of conflict negotiation. Reconciliation, or the attraction and affiliation of former opponents following conflict, has been proposed as a central element of conflict negotiation in chimpanzees and various other taxa. In an attempt to expand the database of chimpanzee conflict resolution, conflict and post-conflict behavior were recorded for a small group of socially housed chimpanzees at the Chimpanzee and Human Communication Institute, at Central Washington University. Data were collected over six 6-week periods between 1997 and 2000, for a total of 840 hours of observation, resulting in a substantial post-conflict (PC) and matched control (MC) data set. The data demonstrate this group's tendencies to maintain visual contact and closer proximity after conflicts. Dyadic corrected conciliatory tendencies ranged between 0 – 37.5% and averaged 17.25% across all dyads. Individual corrected conciliatory tendencies ranged between 5.8 and 32%. The results of this study combined with recent publications on captive and free-ranging chimpanzee post-conflict behavior suggest that variation in post-conflict behavior may be important to our understanding of chimpanzee conflict negotiation, and may also have implications for the design and management of captive chimpanzee enclosures and social groups, respectively. | ||||

Title | Conflict resolution following aggression in gregarious animals: a predictive framework | Type | Journal Article | ||
Year | 2002 | Publication | Animal Behaviour. | Abbreviated Journal | Anim. Behav. |
Volume | 64 | Issue | 3 | Pages | 325-343 |
Keywords | |||||
Abstract | Knowledge of how animals manage their conflicts is critical for understanding the dynamics of social systems. During the last two decades research on gregarious animals, especially primates, has focused on the mechanisms of conflict management, mainly on friendly postconflict reunions (also called `reconciliation') in which former opponents exchange affiliative behaviour soon after an aggressive conflict. Our aim in this paper is to present a framework in which the costs and benefits of friendly postconflict reunions, both for each individual opponent and for their mutual relationship, are used to predict the patterning of postconflict resolution mechanisms in other gregarious animals. The framework predicts the occurrence of postconflict reunions in species that live in stable social units, have individualized relationships, and experience postconflict hostility, but especially in those in which intragroup aggression disrupts valuable relationships. The critical issue is whether aggressive conflicts occur between cooperative partners and whether the level of aggression is sufficient to jeopardize the benefits associated with such valuable relationships. We conclude by proposing four research priorities to evaluate the role of friendly reunions in negotiating relationships and the way they are themselves influenced by asymmetries in partner value and biological market effects.

Title | Conflicting Results in the Association Between Plasma and Salivary Cortisol Levels in Foals | Type | Manuscript | ||
Year | 2002 | Publication | Havemeier Workshop | Abbreviated Journal | |
Volume | Issue | Pages | |||
Keywords | |||||
Abstract | Introduction Glucocorticoids are present in many biological fluids as a free fraction or bound to Corticoid Binding Globulins (CBG) (Matteri et al, 2000). There are conflicting claims regarding the validity of saliva as a biological fluid to measure cortisol in horses (Lebelt et al, 1996; McGreevy and Pell, 1998; van der Kolk et al, 2001). Measuring changes in salivary cortisol levels in normal horses and horses with Cushing`s disease van der Kolk and collaborators (2001) demonstrated the validity of saliva to assess adrenal function. Puzzling results were reported by McGreevy and Pell (1998) who suggested that plasma and salivary cortisol concentrations in horses showing oral stereotypies were correlated but this association was non-existent in control animals. Investigating the responses of foals to branding and foot-trimming Zanella et al (unpublished results) were unable to identify a relationship between plasma and salivary cortisol levels in foals. In several species, levels of cortisol in plasma and saliva are tightly correlated (Fenske, 1996). Cortisol found in blood consists of a fraction bound to corticoid binding globulin (CBG) and a free, unbound fraction. Free cortisol represents the biologically active fraction of this steroid hormone. Salivary cortisol reflects the unbound fraction found in plasma or serum and it passes readily through the parotid membrane (Riad-Fahmy, 1983; Horning Walker et al,1977). Unbound steroids transfer rapidly between plasma and saliva (Walker,1989; Scott et al 1990). Saliva flow-rate does not appear to influence saliva cortisol levels in different species (Hubert and de Jong-Meyer, 1989; Walker 1989, Scott et a, 1990). In horses, Lebelt et al (1996) reported that salivary and plasma total cortisol in stallions were correlated. We hypothesized that changes in salivary cortisol in foals would show a pattern that is correlated to that of plasma free and plasma total cortisol concentrations in foals. In addition, we anticipated that the lack of good sampling techniques provides an explanation for the failure in determining the association between salivary and plasma cortisol in foals. |
