Title Neuroendocrine Mechanisms, Stress Coping Strategies, and Social Dominance: Comparative Lessons about Leadership Potential Type Journal Article
Year 2007 Publication The ANNALS of the American Academy of Political and Social Science Abbreviated Journal Ann Am Acad Polit Soc Sci
Volume 614 Issue 1 Pages 102-130
Keywords social dominance – authoritarian – Five Factor Model – neurochemistry – neurotransmitters – leadership
Abstract The authors examine dominance and subordination in the social psychology, political science, and biology literatures. Using Summers and Winberg (2006) as a guide, the authors suggest that extreme dominance or subordination phenotypes--including social dominance orientation and right-wing authoritarianism--are determined by an organism's genetic predispositions, motivations, stress responses, and long-term hormone release and uptake states. The authors offer hypotheses about the likely neurochemical profiles for each of these extreme dominance and subordination phenotypes and suggest two designs that begin to test these hypotheses.

Title The Wolves of Isle Royale: A Broken Balance Type Book Whole
Year 2007 Publication Abbreviated Journal
Volume Issue Pages

Abstract About the Book

“Few can rival what Rolf Peterson has accomplished on Isle Royale. His study, a true classic, offers lessons and examples to us all who hope to do the same. This book reveals some of the secrets and details of this one-of-a-kind wolf study.”

-Douglas W. Smith, Leader, Yellowstone Wolf Project

For nearly half a century Isle Royale National Park has been the site of a comprehensive study on wolves (2008 marks the fiftieth anniversary)-the world's longest-running study on any wild animal. With its lush northern landscape and wolf and moose populations, the pristine and isolated park presents an ideal laboratory for wildlife biologists.

The Wolves of Isle Royale is author and wildlife biologist Rolf Peterson's fascinating firsthand account of the relationship that exists between the wolf and the moose on the island. Illustrated with over 100 photographs, this book reveals the true nature of the mysterious and little-understood wolf, and it offers novel solutions to the conservation crisis as the wolf population falters to its lowest recorded level.

Rolf O. Peterson is known worldwide for his wolf research. His photographs have been published in National Geographic, Audubon, and National Wildlife. He is Professor of Wildlife Ecology at Michigan Technological University.

Title Evidence For Coevolution Of Sociality And Relative Brain Size In Three Orders Of Mammals Type Journal Article
Year 2007 Publication Evolution Abbreviated Journal
Volume 61 Issue 12 Pages 2811-2821
Keywords Brain size, carnivores, coevolution, primates, sociality, ungulates
Abstract Abstract

As the brain is responsible for managing an individual's behavioral response to its environment, we should expect that large relative brain size is an evolutionary response to cognitively challenging behaviors. The “social brain hypothesis†argues that maintaining group cohesion is cognitively demanding as individuals living in groups need to be able to resolve conflicts that impact on their ability to meet resource requirements. If sociality does impose cognitive demands, we expect changes in relative brain size and sociality to be coupled over evolutionary time. In this study, we analyze data on sociality and relative brain size for 206 species of ungulates, carnivores, and primates and provide, for the first time, evidence that changes in sociality and relative brain size are closely correlated over evolutionary time for all three mammalian orders. This suggests a process of coevolution and provides support for the social brain theory. However, differences between taxonomic orders in the stability of the transition between small-brained/nonsocial and large-brained/social imply that, although sociality is cognitively demanding, sociality and relative brain size can become decoupled in some cases. Carnivores seem to have been especially prone to this.

Title No End to Hierarchy: Does Rank Make a Difference in Perceptions of Leadership Credibility? Type Journal Article
Year 2007 Publication Administration Society Abbreviated Journal Admin. Soc.
Volume 39 Issue 1 Pages 107-123
Keywords hierarchy; leadership; credibility; culture; bureaucracy
Abstract This article investigates whether authority hierarchy still serves as an important factor influencing employee perceptions toward organizational roles and expected behavior. Results of a study in a federal agency suggest that hierarchy does serve as a significant force influencing employee attitudes toward leadership roles, contrary to the notion that hierarchy will diminish in importance over time. Hierarchy remains a crucial structural force in public organizations and is unlikely to wither away.

Title A critical review of fear tests used on cattle, pigs, sheep, poultry and horses Type Journal Article
Year 2007 Publication Physiology & Behavior Abbreviated Journal Physiol. Behav.

Keywords Fear; Cattle; Sheep; Pig; Poultry; Horse; Open field; Tonic immobility; Novel object
Abstract FORKMAN, B., A., BOISSY, M.-C., SALAUN, E., CANALI, AND R.B., JONES. A critical review of fear tests used on cattle, pigs, sheep, poultry and horses. PHYSIOL. BEHAV. 000-000, 2007. Fear is arguably the most commonly investigated emotion in domestic animals. In the current review we attempt to establish the level of repeatability and validity found for fear tests used on cattle, pigs, sheep and goats, poultry and horses. We focus the review on the three most common types of fear tests: the arena test (open field), the novel object test, and the restraint test. For some tests, e.g. tonic immobility in poultry, there is a good and broad literature on factors that affect the outcome of the test, the validity of the test and its age dependency. However, there are comparatively few of these well defined and validated tests and what is especially missing for most tests is information on the robustness, i.e., what aspects can be changed without affecting the validity of the tests. The relative absence of standardized tests hampers the development of applied ethology as a science.

Title Evidence for social role in a dolphin social network Type Journal Article
Year 2007 Publication Evolutionary Ecology Abbreviated Journal Evol. Ecol.
Volume 21 Issue 3 Pages 357-366
Keywords
Abstract Abstract  Social animals have to take into consideration the behaviour of conspecifics when making decisions to go by their daily lives. These decisions affect their fitness and there is therefore an evolutionary pressure to try making the right choices. In many instances individuals will make their own choices and the behaviour of the group will be a democratic integration of everyone’s decision. However, in some instances it can be advantageous to follow the choice of a few individuals in the group if they have more information regarding the situation that has arisen. Here I provide early evidence that decisions about shifts in activity states in a population of bottlenose dolphin follow such a decision-making process. This unshared consensus is mediated by a non-vocal signal, which can be communicated globally within the dolphin school. These signals are emitted by individuals that tend to have more information about the behaviour of potential competitors because of their position in the social network. I hypothesise that this decision-making process emerged from the social structure of the population and the need to maintain mixed-sex schools.

Title Social network theory in the behavioural sciences: potential applications Type Journal Article
Year 2007 Publication Behavioral Ecology and Sociobiology Abbreviated Journal Behav. Ecol. Sociobiol.
Volume 62 Issue 1 Pages 15-27
Keywords Social networks – Social organisation – Mate choice – Disease transmission – Information transfer – Cooperation
Abstract Abstract  Social network theory has made major contributions to our understanding of human social organisation but has found relatively little application in the field of animal behaviour. In this review, we identify several broad research areas where the networks approach could greatly enhance our understanding of social patterns and processes in animals. The network theory provides a quantitative framework that can be used to characterise social structure both at the level of the individual and the population. These novel quantitative variables may provide a new tool in addressing key questions in behavioural ecology particularly in relation to the evolution of social organisation and the impact of social structure on evolutionary processes. For example, network measures could be used to compare social networks of different species or populations making full use of the comparative approach. However, the networks approach can in principle go beyond identifying structural patterns and also can help with the understanding of processes within animal populations such as disease transmission and information transfer. Finally, understanding the pattern of interactions in the network (i.e. who is connected to whom) can also shed some light on the evolution of behavioural strategies.

Title Selective Imitation in Domestic Dogs Type Journal Article
Year 2007 Publication Current Biology Abbreviated Journal Curr Biol
Volume 17 Issue 10 Pages 868-872
Keywords Sysneuro
Abstract Summary The transmission of cultural knowledge requires learners to identify what relevant information to retain and selectively imitate when observing others' skills. Young human infants--without relying on language or theory of mind--already show evidence of this ability. If, for example, in a communicative context, a model demonstrates a head action instead of a more efficient hand action, infants imitate the head action only if the demonstrator had no good reason to do so, suggesting that their imitation is a selective, interpretative process [1]. Early sensitivity to ostensive-communicative cues and to the efficiency of goal-directed actions is thought to be a crucial prerequisite for such relevance-guided selective imitation [2]. Although this competence is thought to be human specific [2], here we show an analog capacity in the dog. In our experiment, subjects watched a demonstrator dog pulling a rod with the paw instead of the preferred mouth action. In the first group, using the “inefficient” action was justified by the model's carrying of a ball in her mouth, whereas in the second group, no constraints could explain the demonstrator's choice. In the first trial after observation, dogs imitated the nonpreferred action only in the second group. Consequently, dogs, like children, demonstrated inferential selective imitation.
