Book Description
Many social primates live in cohesive groups with stable affiliative and agonistic relationships. Although there are species typical patterns of social behavior, there is also individual variation within every species. Sources of individual variation in social behavior include aspects of the physical environment (e.g. availability and distribution of resources and population density), factors of the social environment (e.g. dominance rank and kinship ties), and psychobiological and biological factors (e.g. personality and sex). Understanding the sources of individual variation can inform our understanding of how relationships form as well as variation in larger group dynamics. In the following three chapters I explore the sources of individual variation in affiliative relationships in rhesus macaques (Macaca mulatta). Grooming is an ideal behavior for this task because it is an integral part of the life of social nonhuman primates and species of many other taxa. I begin by looking broadly at grooming patterns in captive and free-ranging social groups, and examine how captive conditions may affect grooming relationships based on age and sex of the initiator and recipient. Results show that adult females, subadult males, and juveniles allocate grooming differently in the wild than in captivity. Adult females and subadult males in captivity have stronger grooming relationships with one another, and weaker grooming relationships with juveniles, than their wild counterparts. In the second chapter I focus on how personality, sex, dominance rank, and prior familiarity shape grooming relationships in captive groups. Prior familiarity is the primary determinant of grooming relationships between individuals, followed by sex, rank, and personality of the grooming initiator. In the final chapter I examine personality variation under different social environments, and show that changes in dominance rank and early experience with high rank predict changes in the expression of boldness, sociability, and impulsivity.

Book Description
Across primates, socially integrated individuals exhibit improved genetic fitness compared to their peripheral conspecifics. However, the mechanisms through which this disparity operates is unclear. One hypothesis is that social bonds mitigate the stressors imparted by environmental instability. To date, this relationship has gone critically unexamined, owing to the inability to anticipate and account for instability in prospective research design. In this dissertation, I evaluate this hypothesis within a population of free-ranging rhesus macaques (M. mulatta). I employ a long-term behavioral data set comprised of 691 unique individuals across 6 groups, followed from 1 to 8 years. I employ the tool-kit of social network analysis to integrate social phenotypes at the individual, dyadic, and group-level. I examine two destabilizing events. First, I examine how affiliation patterns precede a matrilineal overthrow, an outburst of aggression which resulted in group dissolution. As a prelude to this analysis, I investigate the manifestation of rank instability more generally, and, in concert with other dimensions of social life, examine its relationship to psychosocial stress. Second, I examine affiliation in the wake of environmental disaster: here, that of Hurricane Maria, which in 2017 had caused near-complete deforestation. I find that instability leaves an enduring signature in expressions of psychosocial stress. In the context of instability, monkeys show critical transformations in their affiliative patterns--in frequency, variability, and direction--but in ways highly dependent on the type of instability experienced. Such transformations are not experienced uniformly across social units, but instead are concentrated upon those most likely to suffer (or endure) the costs of that instability. This analysis indicates that rhesus monkeys exhibit considerable social flexibility in response to environmental instability and that social bonds, rather than static, are continually renegotiated. Destabilizing events are rare but can impart instantaneously brutal fitness consequences. It is critical, then, that we accumulate case studies of their effects--messy though they may be--to avoid blind spots in our understanding of the evolution of social bonds.

Book Description
The role of play in human development has long been the subject of controversy. Despite being championed by many of the foremost scholars of the twentieth century, play has been dogged by underrepresentation and marginalization in literature across the scientific disciplines. The Oxford Handbook of the Development of Play marks the first attempt to examine the development of children's play through a rigorous and multidisciplinary approach. Comprising chapters from the foremost scholars in psychology, anthropology, and evolutionary biology, this handbook resets the landscape of developmental science and makes a compelling case for the benefits of play. Edited by respected play researcher Anthony D. Pellegrini, The Oxford Handbook of the Development of Play is both a scientific accomplishment and a shot across the bow for parents, educators, and policymakers regarding the importance of children's play in both development and learning.

Book Description
Animal and human societies are multifaceted. In order to understand how they have evolved, it is necessary to investigate each of the constituent facets including individual abilities and personalities, life-history traits, mating systems, demographic dynamics, gene flows, social relationships, ecology and phylogeny. By exploring the nature and evolution of macaque social organization, this book develops our knowledge of the rise of societies and their transformation during the course of evolution. Macaques are the most comprehensively studied of all monkey groups, and the 20 known species feature a broad diversity in their social relationships, making them a particularly good group for exploring the evolution of societies. This book will be of primary interest to those studying animal behaviour and primatology, but will also be useful to those involved in the study of human societies.

Book Description
Abnormal behaviour patterns, from the jumping and somersaulting of caged laboratory mice to the pacing of enclosed 'big cats', are displayed by many millions of farm, zoo, research and companion animals. Including new chapters and over 30 contributors, this book focuses on the causation and treatment of these environment-induced stereotypic behaviours, and their implications for animal welfare and normalcy of brain functioning. The book begins by taking an ethological perspective, focusing on the constraints captivity places on animals' normal behavioural repertoires, and the effects these have on specific motivational systems. It then addresses the role of dysfunction, particularly the impact of chronic stress and impoverished environments on brain functioning. The book then moves on to explore how stereotypic behaviours can be tackled, once they have emerged, using diverse techniques from environmental enrichment to pharmaceutical intervention. It concludes by giving a new definition for 'stereotypic behaviour', and a discussion of future research directions.
