  1. Crying wolf: The unlawful delisting of northern rocky mountain gray wolves from endangered species act protections

    Contributor(s):: Jesse H. Alderman

    Although settlers hunted gray wolves to near extinction more than a century ago, the animal remains one of the most enduring symbols of the West. In 1994, the U.S. Fish & Wildlife Service authorized reintroduction of gray wolves into Idaho, Montana, and Wyoming under recovery provisions of the...

  4. The effect of environmental enrichment on play behaviour in white-lipped peccaries ( Tayassu pecari )

    | Contributor(s):: Nogueira, S. S. C., Soledade, J. P., Pompeia, S., Nogueira Filho, S. L. G.

    Herds of white-lipped peccary (Tayassu pecari) have historically been kept in captivity in order to replace stocks lost to hunting however the lack of knowledge regarding their species-typical behaviour remains an impediment to understanding their captive needs. Environmental enrichment has been...

  5. A comparative approach to the study of Keeper-Animal Relationships in the zoo. (Special Issue: Zoo animal welfare.)

    | Contributor(s):: Carlstead, K.

    Research on intensively farmed animals over the past 25 years has shown that human-animal interactions, by affecting the animal's fear of humans, can markedly limit the productivity and welfare of farm animals. This article begins to explore some of the factors that need to be considered to...

  6. Animal welfare in the musk deer [ Moschus chrysogaster ]

    | Contributor(s):: Shrestha, M. N.

  7. Straw collecting behaviour by pacas ( Agouti paca ) in captivity

    | Contributor(s):: Sabatini, V., Costa, M. J. R. P. da

    Agouti paca is both considered as a species vulnerable to extinction and recognised with the potential for domestication. In spite of this, its behaviour is poorly documented and captive breeding is mainly based on trial and error. The aim of the present research was to analyse whether different...

  8. A preliminary study into the effectiveness of stroboscopic light as an aversive stimulus for fish

    | Contributor(s):: Mesquita, F. de O., Godinho, H. P., Azevedo, P. G. de, Young, R. J.

    To reduce fish mortality in nature it is often necessary to expel individuals from areas modified by humans (e.g., dams) where they could be injured or killed. We tested the effectiveness of stroboscopic light as an aversive stimulus for zebrafish (Danio rerio) in captivity. We used six groups of...

  9. Behavioural evidence of hybridization (Japanese x European) in domestic quail released as game birds

    | Contributor(s):: Deregnaucourt, S., Guyomarc'h, J. C., Spano, S.

    The European quail is a partial migrant bird considered 'vulnerable' by the European community. The decline of this subspecies has spurred an annual release of large numbers of domestic Japanese quail. Prezygotic and postzygotic isolating mechanisms have not been established between these two...

  10. Physical attractiveness of an animal species as a decision factor for its preservation

    | Contributor(s):: Gunnthorsdottir, A.

    This experimental study examines how framing an animal species as endangered affects its perceived attractiveness and how an animal's perceived attractiveness affects support for its conservation. Undergraduate students were shown a flyer from a fictitious environmental organization pleading for...

  11. Behaviour of a captive pair of clouded leopards ( Neofelis nebulosa ): introduction without injury

    | Contributor(s):: Law, G., Tatner, P.

  12. Faecal glucocorticoid level is not correlated with stereotypic pacing in two captive margays ( Leopardus wiedii )

    | Contributor(s):: Gusset, M.

    The 'coping hypothesis' of stereotypic behaviour - that stereotypies are performed as a means of helping the animal to cope with its environment by reducing stress - was tested using two adult female margays (Leopardus wiedii), an endangered neotropical small cat species. Within-individual and...

  13. Ethics and animal welfare in wild primates

    | Contributor(s):: Oliveira, M. A. B. de

    The concept of 'ethics' is usually applied, among primates, to humans only. This article argues that it should also be applied to non-human primates. Brazil is the 'guardian' of the most rich and diverse - and threatened - fauna of non-human primates in the world. Of 103...

  14. Human-animal bond: endangered birds, the environment and the veterinarian's role
