Available in PDF, EPUB and Kindle. Book excerpt: This book integrates three decades of owl monkey research conducted since 1994 when the first and only book focused on the genus Aotus was published. Owl monkeys were one of the least understood primates then; knowledge from wild populations was only beginning to emerge and there had been some substantial research in colonies of captive individuals. The situation is very different today. Research on captive owl monkeys has continued to develop, with valuable contributions to the health and medical sciences. And there is now enough information on the behavior, ecology, conservation, and biogeography of the genus that merits a synthesis. The book synthesizes new field data on the biogeography, behavioral ecology, circadian biology, population biology and demography spanning their entire continental range from Panamá to Argentina. It includes theoretical perspectives drawn from evolutionary biology, biological anthropology, anatomy, morphology and physiology, genetics, endocrinology and conservation biology to examine a specic set of adaptations that have allowed owl monkeys to exploit the nocturnal niche while functioning in a pair-living sexually monogamous system with remarkable patterns of paternal care. The author, with 30 years of research experience with both captive and wild primates, has directed the longest project on any owl monkey species and has conducted extensive original research on their biology, adaptive radiation and behavioral ecology. His expertise and published record on both wild populations and laboratory colonies makes this book one of a kind; it presents information from both captive and wild primates and explores questions through the integration of both approaches. The volume offers some additional features that make it novel in its approach: (1) brings together a combination of senior researchers who during four decades have established captive owl monkeys as a system of study with a new generation of younger scientists who have, for the last 10-20 years, been spearheading their study in the wild, (2) presents the work of a remarkably diverse range of authors representing all countries where owl monkeys are present, as well as researchers from the U.S and Europe, and (3) offers “synthesis” chapters; in doing so, it will surely become a reference book for those specifically drawn to owl monkeys, as well as for those interested in the research topics that are covered.

Book excerpt: Natal dispersal, the movement of individuals from their birthplace to new areas in which they may breed, is an important aspect of life history that influences a variety of processes. Understanding dispersal not only increases our theoretical knowledge of the evolution of mating systems and social dynamics, but also provides insights essential for effective population management and for predicting the consequences that environmental changes may have on species' distributions. This dissertation takes a holistic approach to explore natal dispersal at the level of the population, group, and individual in Azara's owl monkey (Aotus azarae), a social monogamous primate native to South America. All data presented in this dissertation were collected at a long-term field site of the Owl Monkey Project in the Gran Chaco region of Formosa, Argentina. Chapter two examines dispersal at the level of the community, by exploring how demographic changes and environmental variables are associated with dispersal. The timing of dispersal was highly flexible, suggesting that delaying dispersal may be an adaptive strategy that owl monkeys utilize to minimize dispersal costs and maintain access to benefits provided by the natal group. Chapter three narrows the focus to the level of the group, and finds that behaviors, particularly agonism among group members, may function to regulate dispersal as well as mediate competition amongst adults and predispersed offspring. The next two chapters narrow the focus even further, to the individual level. Chapter four, which examines hormonal correlates of development and dispersal, finds that females experience the onset of sexual maturity prior to dispersing. Chapter five follows dispersing individuals thorough the entire process of dispersal to investigate the ultimate fates of dispersers. Dispersal strategies were highly variable, but individuals often prospected prior to permanently dispersing and almost always spent time as solitary "floaters." Together, these investigations provide insight into both proximate and ultimate causes for dispersal and allow for the development of a multifaceted understanding of dispersal patterns in a socially monogamous primate. The holistic approach to understanding dispersal taken in this dissertation is one that could be useful for increasing our understanding of dispersal in many other taxa.

Download or read book Titi Monkey Callicebus Cupreus Pair bonds and the Role of mu and kappa Opioid Receptors written by Benjamin J. Ragen and published by . This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The opioid system is involved in a variety of behavioral and physiological functions. The opioid system, especially the [mu] opioid receptor (MOR) has been well established to be involved in infant-mother bonds as well as regulating social behavior in non-monogamous primates. Recent research in the monogamous prairie vole has provided evidence for the MOR and the [kappa] opioid receptor (KOR) to regulate pair-bond formation and maintenance. The following series of studies aimed at expanding this research to the monogamous titi monkey (Callicebus cupreus) and to explore how the MOR and KOR affect social behavior and endocrine functioning. For Study 1, paired male titi monkeys were administered the MOR agonist, morphine, and the opioid antagonist, naloxone, in the presence and absence of their pair-mate. Morphine attenuated the increase in plasma cortisol in response to separation and naloxone increased cortisol. Opioid manipulation had no effect on social or separation distress behavior, however, the presence of a pair-mate attenuated naloxone's aversive effects, which manifest as an increase in locomotion, cortisol, and vasopressin. For Study 2, paired male titi monkeys received morphine, naloxone, or the KOR agonist U50,488 upon reunion after a brief separation as well as whether. Morphine administration resulted in a reduction of males initiating contact and proximity with the female with the females compensating for the decrease in social motivation by breaking contact less. KOR activation resulted in slight increase in cortisol. Experiment 2 of Study 2, administered the KOR antagonist, GNTI, to observe if it would attenuate the separation distress response. GNTI attenuated the locomotor component of the separation distress response. The aim of Study 3 was to examine the distribution of MORs and KORs. Mapping of MORs and KORs with [3H]DAMGO and [3H]U69,593, respectively, uncovered that there was binding in the striatum, cingulate cortex, amygdala, and hypothalamus. These are all brain regions involved in social behavior and endocrine function. These studies are the first to provide evidence that MORs and KORs in a monogamous primate regulate endocrine functioning and key behaviors important for maintaining a pair-bond.
Download or read book Understanding Behavior and Nest Box Usage in Three Species of Owl Monkeys written by Leilani Case and published by . This book was released on 2013 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of tree holes and nest building behavior is uncommon among most primate species. In research facilities that house species requiring nesting sites, such as those that use tree holes in the wild, providing nest boxes is crucial to their psychological well-being. The goal of this study was to determine nest box preferences among three species of captive owl monkeys: Azara's owl monkey (Aotus azarai), Nancy Ma's owl monkey (A. nancymaae) and Spix's owl monkey (A. vociferans). The subjects were housed at The University of Texas M.D. Anderson: Keeling Center for Comparative Medicine and Research Core and Animal Resources, Bastrop, TX. Five family groups from each species, ranging from 2-5 individuals, were observed for location and behavior from 21 June 2012 to 23 August 2012. The facility provided four different types of nest boxes: [1] a mesh box, [2] a covered box of the same size, [3] a horizontal bucket, and [4] an opaque white box. As a nocturnal species, the owl monkeys are maintained on a partial reverse light cycle and the rooms are equipped with louvers, allowing the owl monkeys to experience a "dusk" period in the lighting. While A. azarai spend more of their sleeping time in dense foliage in the wild compared to A. nancymaae and A. vociferans, in the current study, although they were provided with nest boxes meant to mimic this type of nesting site, A. azarai did not spend more time (13.6+19.1%) in the nest boxes compared to the other two species (A. vociferans 18.4+18.8% and A. nancymaae 8.1+18.0%). All three species employed a variety of sleeping sites including the nest boxes as well as other cage substrates such as the floor and perches. One factor contributing to sleep site selection was the size of the group and the size of the nest box. A. azarai are generally considered more cathemeral than the other species. In the current study, the activity level of A. azarai was much higher (77.3 + 15% resting) compared to A. nancymaae (93.3 + 11) or A. vociferans (97.9+3) during the dusk period. Dusk is usually a peak time for all owl monkey species to forage and to travel; however, in captivity the pattern may be different.

Download or read book The Neurobiological and Physiological Basis of Pair Bond Maintenance Behavior in Socially Monogamous Titi Monkeys Callicebus Cupreus written by Emily Spray Rothwell and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Pair bond relationships may be stable over time, but the behavioral interactions involved in maintaining these enduring social bonds are dynamic over time. Capturing and understanding these social complexities is difficult and likely contributes to the fact that there is far less literature regarding the maintenance of long-term pair bonds compared to their formation. The goal of my dissertation was to probe the neurobiological and physiological basis of behaviors that contribute to pair bond maintenance. I studied this in captive coppery titi monkeys (Callicebus cupreus), a New World primate species that reliably display pair bonding in the wild and the laboratory. In chapter 1, I explored the role of the dopamine system in arousal and mate guarding behavior in male titi monkeys. For chapter 2, I characterized differences in behavioral dynamics between partners from newly-formed compared to well-established pairs of titi monkeys. Finally for chapter 3 I explored the influence of pair bond characteristics on the regulation of physiological responses during a challenge to the relationship.
