  1. Reinforcing Marine Conservation Messages: Case Study at the Houston Zoo

    Contributor(s):: Heather L. Crane

    The Houston Zoo has been involved in conservation efforts worldwide for many years. However, in 2015, the Houston Zoo pledged to make conservation its priority and improve upon the existing conservation programs. In 2015, the Houston Zoo developed partnerships with 28 conservation organizations...

  2. Orca Behavior and Subsequent Aggression Associated with Oceanarium Confinement

    Full-text: Available

    | Contributor(s):: Robert Anderson, Robyn Waayers, Andrew Knight

    Based on neuroanatomical indices such as brain size and encephalization quotient, orcas are among the most intelligent animals on Earth. They display a range of complex behaviors indicative of social intelligence, but these are difficult to study in the open ocean where protective laws may...

  3. Hair plucking in captive bonobos ( Pan paniscus)

    | Contributor(s):: Brand, C. M., Marchant, L. F.

    Both wild and captive studies of grooming in non-human primates emphasize the adaptive role of this behavior. Indeed, social grooming is frequently characterized as "social glue" in the life of primates. Grooming behavior is studied to reveal dominance, kin relations, and social networks. Many...

  4. Do Visitors Affect Zebra Behavior in Zoos?

    | Contributor(s):: Christine Conte

    I investigated the effects of visitors on the behavior of two zebra species (Equus grevyi and Equus burchelli) at eight zoos on the East Coast of the United States. I used instantaneous time sampling to record zebra behavior and visitor data. I used these data to run Bayesian hierarchical models...

  5. The Zoological Paradox

    | Contributor(s):: Thorfun Chutchawanjumrut

    Through on-site field investigation, studies of animal behaviors, and Jon Coe’s zoo enrichment principles, this thesis proposes that zoo architec-ture should prioritize the needs of the animals by incorporating behavioral and environmental enrichments into its...

  6. Applying visitor preference criteria to choose pro-wildlife behaviors to ask of zoo visitors

    | Contributor(s):: Liam Smith, Betty Weiler, Amy Smith, Pieter van Dijk

    Many zoos now emphasize that their role in conservation includes influencing the behavior of their visitors for the benefit of wild animals. However, there is limited evidence of behavioral change to support this emphasis; one reason may be that requested behaviors are not viewed favorably by zoo...

  8. An hourly variation in zoo visitor interest: measurement and significance for animal welfare research

    | Contributor(s):: Davey, G.

    A methodological difficulty facing welfare research on nonhuman animals in the zoo is the large number of uncontrolled variables due to variation within and between study sites. Zoo visitors act as uncontrolled variables, with number, density, size, and behaviour constantly changing. This is...

  9. Behavioral management at the Phoenix Zoo: new strategies and perspectives

    | Contributor(s):: Tresz, H.

    It all started with a seemingly simple decision to re-evaluate and document the Phoenix Zoo's behavioral management protocol. The purpose of this project was to present proactive standards for the care and psychological well-being of our living collection, while meeting or exceeding the...

  10. Distressed animal behaviors and some recommendations for improvements at the Kuala Lumpur Zoo, Malaysia

    | Contributor(s):: Amber, Haque

    The artificial living conditions of captive animals present numerous challenges for animal caretakers. In this study I explored abnormal behaviors in certain caged animals at the Kuala Lumpur Zoo. Findings obtained from observations of animals and interviews of the zoo staff are followed by...

  11. Effect of enclosure quality on reactivity and welfare of captive Soemmerring's gazelle ( Gazella soemmerringii )

    | Contributor(s):: Mansour, A. A. H., Zakaria, A. H., Fraser, A. F.

    The welfare of nonhuman animals in zoos is a great challenge to the zookeeper. Changes in the behavioral response of captive animals to their immediate environment can be used as a method for evaluating their welfare status. This study evaluates reactive responses of 3 groups of captive...

  12. Influence of zoo visitor presence on the behavior of captive Indian gaur ( Bos gaurus gaurus ) in a Zoological Park

    | Contributor(s):: Mahadevan, Sekar, Thangavel, Rajagopal, Govindaraju, Archunan

    Visitors to zoos can be a source of potential disturbance and stress to some captive, nonhuman animals in the wild. To determine the influence of visitor presence on captive bison (Bos gaurus gaurus), the study analysed the behaviour of 4 individuals at the Arignar Anna Zoological Park, India....

  13. Introducing a semi-naturalistic exhibit as structural enrichment for two brown bears ( Ursus arctos ). Does this ensure their captive well-being?

    | Contributor(s):: Soriano, A. I., Ensenyat, C., Serrat, S., Mate, C.

    In this study we used the daily activity pattern and use of space as indicators of change in the program of structural enrichment, implemented with 2 subjects of the species Ursus arctos in the Barcelona Zoo. We collected 930 sampling points in each study phase for each of the individuals: The...

  14. Reaching new heights: the effect of an environmentally enhanced outdoor enclosure on Gibbons in a zoo setting

    | Contributor(s):: Anderson, M. R.

    Gibbons have adapted to live in the canopy layer of the rainforest. Gibbons in the wild predominantly spend their time high in the trees resting, traveling, and foraging for food. Comparatively, gibbons in the zoo often rest and search for their food terrestrially. The purpose of this study was...

  15. Retreat space and human visitor density moderate undesirable behaviour in petting zoo animals

    | Contributor(s):: Anderson, U. S., Benne, M., Bloomsmith, M. A., Maple, T. L.

    This study focused on the relationship between nonhuman animal behaviour and environment - specifically, between the undesirable behaviour exhibited by domestic petting zoo animals in the presence of humans and the spatial design of the petting zoo environment. A spatial feature of a petting zoo...

  16. Toward a science of welfare for animals in the zoo

    | Contributor(s):: Maple, T. L.

    Although the accredited institutions of the Association of Zoos and Aquariums have all committed to enhancing the welfare of nonhuman animals, acceptable standards and best practices are still under debate. Currently, experts from zoos and the field hold widely divergent opinions about exhibition...

  17. Use of enclosure space by captive lion-tailed macaques ( Macaca silenus ) housed in Indian zoos

    | Contributor(s):: Avanti, Mallapur, Waran, N., Anindya, Sinha

    Captive nonhuman animals use enclosure space differentially. Enclosure features strongly influence this. This study recorded both the enclosure space used by 47 captive lion-tailed macaques housed in 13 zoos across India and the behaviour of the macaques. The exhibition of abnormal behaviors,...

  18. Visitors' effects on the welfare of animals in the zoo: a review

    | Contributor(s):: Davey, G.

    Since the 1970s, research about zoo visitors' effects on the welfare of nonhuman animals in captivity has intensified. Numerous studies have shown that characteristics such as visitor presence, density, activity, size, and position are associated with animal behavioral and - to a lesser extent...

  19. Ratings of animal personality as a tool for improving the breeding, management and welfare of zoo mammals

    | Contributor(s):: Tetley, C. L., O'Hara, S. J.

  20. Public perceptions of behavioral enrichment: assumptions gone awry
