  1. Use of Primates in Research: What Do We Know About Captive Strepsirrhine Primates?

    The increasing debate and restrictions on primate research have prompted many surveys about their status. However, there is a lack of information regarding strepsirrhine primates in the literature. This study provides an overview of research on strepsirrhines in captivity by analyzing scientific...

  2. Complexities of Using Wild versus Captive Activity Budget Comparisons for Assessing Captive Primate Welfare

    Activity budget comparisons between groups or individuals in the wild and those in captivity are commonly used to determine the range of wild-type behaviors that nonhuman animals in captivity perform. These comparisons are conducted with the view that individuals displaying a greater range of...

  3. Visitor Perceptions of Captive, Endangered Barbary Macaques (Macaca sylvanus) Used as Photo Props in Jemaa El Fna Square, Marrakech, Morocco

    Visitors to Jemaa El Fna Square can pay to have their photograph taken with Barbary macaques. Our aim was to characterize visitors’ perceptions of such photo props, enabling demand-reducing interventions to be targeted appropriately and destination managers to maintain or enhance the visitor...

  4. Motivations for the Ownership of Captive Lemurs in Madagascar

    The live capture of primates is occurring throughout the tropics and can be a threat to their conservation. Primates are owned as pets for a variety of reasons. Studies of the motivations for primate ownership have been conducted in several countries where they are endemic, but no study has...

  5. Social housing of surplus males of Javan langurs (Trachypithecus auratus): Compatibility of intact and castrated males in different social settings

    Javan langurs (Trachypithecus auratus) naturally form social groups containing typically only one adult male. However, this social system is problematic with regard to captive management, as it can lead to the production of surplus males. The study assessed if castration is a feasible strategy to...

  6. The psychology of control: Effects of control over supplementary light on welfare of marmosets

    It is often argued that increasing the amount of control that animals have over various aspects of their environment has a positive effect on their welfare, despite limited empirical evidence. We gave 12 pairs of common marmosets (Master pairs) control over supplementary light in their cages...

  7. Benefits of pair housing are consistent across a diverse population of rhesus macaques

    Introducing singly housed rhesus macaques (Macaca mulatta) into isosexual pairs is widely considered to improve welfare. The population of laboratory rhesus macaques is heterogeneous on a variety of factors and there is little literature available to directly evaluate the influence of many of...

  8. Association of antimicrobial resistance and gut microbiota composition in human and non-human primates at an urban ecotourism site

  9. High rates of aggression do not predict rates of trauma in captive groups of macaques

    Socially inflicted traumas are a major concern for the management of captive groups of rhesus macaques. Rhesus macaques are the most commonly used nonhuman primate in biomedical research, and social housing is optimal for promoting psychological well-being. However, trauma is frequent due to a...

  10. Visitor effects on zoo-housed Sulawesi crested macaque (Macaca nigra) behaviour: Can signs with ‘watching eyes’ requesting quietness help?

    Visiting public can cause changes in the behaviour of zoo-housed primates. These effects, if indicative of stress, can be of welfare concern. However, few options to mitigate visitor effects through modulating visitor behaviour have been explored. Here we evaluated the effects of visitor number...

  11. A protocol for training group-housed rhesus macaques (Macaca mulatta) to cooperate with husbandry and research procedures using positive reinforcement

    There has been increased recognition of the 3Rs in laboratory animal management over the last decade, including improvements in animal handling and housing. For example, positive reinforcement is now more widely used to encourage primates to cooperate with husbandry procedures, and improved...

  12. Happiness is positive welfare in brown capuchins (Sapajus apella)

    Questionnaires that allow people who are familiar with individual animals to rate the welfare of these animals are an underutilised tool. We designed a 12-item welfare questionnaire and tested its reliability and associations with subjective well-being (SWB), locomotor stereotypy, and personality...

  13. Training success in group-housed long-tailed macaques (Macaca fascicularis) is better explained by personality than by social rank

    Using training to prepare laboratory animals for biomedical research is one important behavior management task. With increased knowledge about factors influencing training success, training programs may be optimized, resulting in a refinement of primate husbandry. Even when animals are trained...

  14. Female social behaviour during three male introductions in captive groups of rhesus macaques

    Introductions of new males into captive primate groups are often necessary to prevent inbreeding, but also bear high social risks. To minimize these risks, it is crucial to understand the social behaviour accompanying male introductions. While the behaviour of new males is generally understood,...

  15. Hormonal correlates of behavioural profiles and coping strategies in captive capuchin monkeys (Sapajus libidinosus)

    In this study, we tested the hypothesis that individual differences in behavioural profiles correlate to differences in stress-related behaviours and hormonal levels in captive brown capuchin monkeys (Sapajus libidinosus). Based on a sample of 25 animals, 143 h of behavioural data collection and...

  16. Rabies in Nonhuman Primates and Potential for Transmission to Humans: A Literature Review and Examination of Selected French National Data

    Journal Articles

    Background: The nonhuman primate (NHP)-related injuries in rabies-enzootic countries is a public health problem of increasing importance. The aims of this work are to collect data concerning rabies transmission from NHPs to humans; to collate medical practices regarding rabies postexposure...

  17. Overweight and obese pet owners: respondent and pet characteristics in the rural Midwestern United States

    Journal Articles

    The obesity epidemic has impacted both people and pets in the rural Midwestern United States (MWUS). Tailoring health advice to the socio-demographic characteristics and dietary patterns of owners and their pets can help promote adherence to health behavior changes for owners and foster health...

  18. Virtue, Vice, and "Voracious" Science: How should we approach the ethics of primate research?

    Journal Articles

  19. Practices and Perceptions of Animal Contact and Associated Health Outcomes in Pregnant Women and New Mothers

    Journal Articles

    Companion animals play an important role in our society. However, pregnant women and new mothers might have specific concerns about animal-associated health outcomes because of their altered immune function and posture as well as their newborn babies. The study was conducted to collect baseline...

  20. Dog as a typical predator which communicates with manPies jako typowy drapieznik komunikujacy sie z czlowiekiem

    Journal Articles

    This article aims at the presentation of a complex process of making ties between the dog and the man, that started from the domestication of a dog and was followed by the thousands years of co-evolution. Here, we were discussing the process of forming relationships between the dog and the man up...
