  1. A cross-species comparison of abnormal behavior in three species of singly-housed old world monkeys

    Contributor(s):: Lutz, Corrine K.

    Abnormal behavior occurs in a number of captive nonhuman primate species and is often used as an indicator of welfare. However, reported levels of abnormal behavior often vary across species, making general welfare judgments difficult. The purpose of this study was to assess differences in levels...

  2. Effacing the human: Rachel Rosenthal, rats and shared creative agency

    Contributor(s):: Carrie Rohman

  3. When dogs look back: inhibition of independent problem-solving behaviour in domestic dogs ( Canis lupus familiaris) compared with wolves ( Canis lupus)

    Contributor(s):: Udell, M. A. R.

    Domestic dogs have been recognized for their social sensitivity and aptitude in human-guided tasks. For example, prior studies have demonstrated that dogs look to humans when confronted with an unsolvable task; an action often interpreted as soliciting necessary help. Conversely, wolves persist...

  4. The Role of Hybridization and the United States Fish and Wildlife Service Biologists' Discretion in the Implementation of the Endangered Species Act

    Contributor(s):: Jennifer F. Lind-riehl

    The Endangered Species Act (ESA) requires that the “best available scientific and commercial data” be used to enable the protection of critically imperiled species from extinction and preserve biodiversity. However, the ESA does not provide specific guidance on how to apply this...

  5. Abnormal behavior in caged birds kept as pets

    Contributor(s):: Hoek, C. S. van, Cate, C. ten

    There are a limited number of studies dealing with abnormal behavior in caged birds kept as pets. However, these studies demonstrate the presence of abnormal behavior in both songbirds and parrots. Ethological studies on these birds, as well as studies on domestic and zoo birds, indicate that...

  6. And say the cat responded? Getting closer to the feline gaze

    Contributor(s):: White, K.

  7. Animals in war, animals on war: new perspectives from a theater of species

    Contributor(s):: Chaudhuri, U.

  8. The effect of morphine on changes in behaviour and physiology in intraperitoneally vaccinated Atlantic salmon ( Salmo salar)

    Contributor(s):: Nordgreen, J., Bjorge, M. H., Janczak, A. M., Poppe, T., Koppang, E. O., Ranheim, B., Horsberg, T. E.

  9. A framework for assessing the suitability of different species as companion animals

    Contributor(s):: Schuppli, C. A., Fraser, D.

  10. Guidelines for police officers when responding to emergency animal incidents

    Contributor(s):: Hanyok, P. M.

  11. External characteristics and associated developmental changes in two species of Sulawesi macaques, Macaca tonkeana and M. hecki, with special reference to hybrids and the borderland between the species

    Contributor(s):: Watanabe, Kunio, Lapasere, Harun, Tantu, Ramli

  12. A Comparative Study of the Use of Visual Communicative Signals in Interactions Between Dogs (Canis familiaris) and Humans and Cats (Felis catus) and Humans

    Contributor(s):: Miklósi, Áam, Pongrácz, Péter, Lakatos, Gabriella, Topál, József, Csányi, Vilmos

  13. A review of domestic dogs' (canis familiaris) human-like behaviors: Or why behavior analysts should stop worrying and love their dogs

    Contributor(s):: Udell, Monique A. R., Wynne, C. D. L.

  14. Behaviour of temperate and sub-tropical reef fishes towards a stationary SCUBA diver

    Contributor(s):: Watson, Dianne L., Harvey, Euan S.

  15. Breed differences in domestic dogs' (Canis familiaris) comprehension of human communicative signals

    Contributor(s):: Wobber, Victoria, Hare, Brian, Koler-Matznick, Janice, Wrangham, Richard, Tomasello, Michael

  16. Nonapeptide mechanisms of social cognition, behavior and species-specific social systems

    Contributor(s):: Goodson, James L., Thompson, Richmond R.

  17. Species-Specific Differences and Similarities in the Behavior of Hand-Raised Dog and Wolf Pups in Social Situations with Humans

    Contributor(s):: Gácsi, Márta, Gy?ri, Borbála, Miklósi, Ádám, Virányi, Zsófia, Kubinyi, Enik?, Topál, József, Csányi, Vilmos

    In order to reveal early species-specific differences, we observed the behavior of dog puppies (n = 11) and wolf pups (n = 13) hand raised and intensively socialized in an identical way. The pups were studied in two object-preference tests at age 3, 4, and 5 weeks. After a short isolation, we...

  18. The evolution of social play

    Contributor(s):: Pellis, Sergio M., Pellis, Vivien C., Reinhart, Christine J.

  19. Comparative behaviour of free-ranging blackbirds ( Turdus merula ) and silvereyes ( Zosterops lateralis ) with hexose sugars in artificial grapes

    Contributor(s):: Saxton, V. P., Hickling, G. J., Trought, M. C. T., Creasy, G. L.

    In order to detect bird responses to sugar parameters of ripening grapes, artificial grapes containing controlled concentrations of hexose sugars were offered to free-range blackbirds (Turdus merula) and silvereyes (Zosterops lateralis). Time-lapse video was used to observe the two species of...

  20. Do the stereotypies of pigs, chickens and mink reflect adaptive species differences in the control of foraging?

    Contributor(s):: Mason, G., Mendl, M.

    Species differences in food-related stereotypies and natural foraging behaviour are discussed, and evolutionary explanations for these species differences, and reasons why apparent species differences in stereotypy may be artefacts of husbandry are postulated.
