  1. Food puzzles for cats: feeding for physical and emotional wellbeing

    Contributor(s):: Dantas, L. M. S., Delgado, M. M., Johnson, I., Buffington, C. A. T.

    Practical relevance: Many pet cats are kept indoors for a variety of reasons (eg, safety, health, avoidance of wildlife predation) in conditions that are perhaps the least natural to them. Indoor housing has been associated with health issues, such as chronic lower urinary tract signs, and...

  2. Converging on ancient bones: a review of the evidence for the close relatedness of humans ( Homo sapiens) and spotted hyenas ( Crocuta crocuta)

    Contributor(s):: Baynes-Rock, M.

    The majority of spotted hyena studies are conducted in places such as national parks and reserves where there are few humans present other than the researchers. I argue that this reflects a perception that "real" hyenas are those largely unaffected by contact with humans. This is at odds with...

  3. Are farmed salmon more prone to risk than wild salmon? Susceptibility of juvenile farm, hybrid and wild Atlantic salmon Salmo salar L. to an artificial predator

    Contributor(s):: Solberg, M. F., Zhang, ZhiWei, Glover, K. A.

    Offspring of farmed Atlantic salmon have been documented to display lower survival than the offspring of wild salmon in the wild. It has been suggested that reduced survival of farmed salmon offspring in the wild could, in part, be explained by increased susceptibility to predation through...

  4. Ranging characteristics of the domestic cat ( Felis catus) in an urban environment

    Contributor(s):: Thomas, R. L., Baker, P. J., Fellowes, M. D. E.

    In many countries, high densities of domestic cats ( Felis catus) are found in urban habitats where they have the potential to exert considerable predation pressure on their prey. However, little is known of the ranging behaviour of cats in the UK. Twenty cats in suburban Reading, UK, were fitted...

  5. Managing feral cats on a university's campuses: how many are there and is sterilization having an effect?

    Contributor(s):: Jones, A. L., Downs, C. T.

    Worldwide domestic and feral cat (Felis catus) numbers have increased. Concerns regarding high populations of feral cats in urban areas include wildlife predation, public nuisance, and disease. This study aimed to estimate the size of the feral cat population on 5 campuses of the University of...

  6. Using sterilization to change predation rates of wild coyotes: a test case involving pronghorn fawns

    Contributor(s):: Seidler, R. G., Gese, E. M., Conner, M. M.

    Surgical sterilization of coyotes ( Canis latrans) reduced their predation rate on domestic sheep. We investigated whether sterilizing coyotes would similarly change coyote predation rates on pronghorn antelope ( Antilocapra americana) neonates. From May 2006 to March 2008, we radio-collared 71...

  7. Assessing the safety of collars used to attach predation deterrent devices and ID tags to pet cats

    Contributor(s):: Calver, M. C., Adams, G., Clark, W., Pollock, K. H.

  8. Local tolerance of hyena attacks in east Hararge Region, Ethiopia

    Contributor(s):: Baynes-Rock, M.

  9. The acquisition and maintenance of dogs' aversion responses to kiwi ( Apteryx spp.) training stimuli across time and locations

    Contributor(s):: Dale, A. R., Statham, S., Podlesnik, C. A., Elliffe, D.

  10. Cow dogs: use of livestock protection dogs for reducing predation and transmission of pathogens from wildlife to cattle

    Contributor(s):: VerCauteren, K. C., Lavelle, M. J., Gehring, T. M., Landry, J. M.

  11. Gregarious nesting - an anti-predator response in laying hens

    Contributor(s):: Riber, A. B.

  12. Water-site selection and behaviour of red-legged partridge Alectoris rufa evaluated using camera trapping

    Contributor(s):: Sanchez-Garcia, C., Armenteros, J. A., Alonso, M. E., Larsen, R. T., Lomillos, J. M., Gaudioso, V. R.

  13. Vigilance, time budgets and predation risk in reintroduced captive-bred grey partridges Perdix perdix

    Contributor(s):: Rantanen, E. M., Buner, F., Riordan, P., Sotherton, N., Macdonald, D. W.

    Anti-predator behaviour has direct fitness consequences for prey species and thereby affects their reintroduction success, which has generally been poor. Development of anti-predator behaviour may be impaired in captive conditions which favour low emotional reactivity, resulting in poor...

  14. Artificial illumination reduces bait-take by small rainforest mammals

    Contributor(s):: Bengsen, A. J., Leung, L. K. P., Lapidge, S. J., Gordon, I. J.

    Small mammals often moderate their foraging behaviour in response to cues indicating a high local predation risk. We assessed the ability of cues associated with a high predation risk to reduce the consumption of bait by non-target small mammal species in a tropical rainforest, without inhibiting...

  15. Attention, noise, and implications for wildlife conservation and management

    Contributor(s):: Chan, A. A. Y. H., Blumstein, D. T.

    Anthropogenic stimuli are often viewed as disturbances that directly interfere with signal processing or communication, or directly harm animals. However, such sounds may also distract individuals and thus potentially interfere with their ability to make biologically important decisions about...

  16. Behavioural and corticosterone responses to capture and confinement of wild blackbirds ( Turdus merula )

    Contributor(s):: Adams, N. J., Farnworth, M. J., Rickett, J., Parker, K. A., Cockrem, J. F.

    Capture and temporary confinement of wild birds are integral parts of wildlife management practice and research used, for example, during translocation or reintroduction initiatives. We report here on the behavioural and stress hormone (corticosterone) responses of wild blackbirds (Turdus merula)...

  17. Bold, shy, and persistent: variable coyote response to light and sound stimuli

    Contributor(s):: Darrow, P. A., Shivik, J. A.

    To improve frightening device technology for managing predation, we examined variation in coyote (Canis latrans) response to visual, auditory, and combined stimuli using a behavior-contingent programmable frightening device. We hoped to gather information on the relative effectiveness of light,...

  18. Behavioural patterns in ewe-lamb pairs and vulnerability to predation by wolverines

    Contributor(s):: May, R., Dijk, J. van, Forland, J. M., Andersen, R., Landa, A.

    In Norway domestic sheep Ovis aries range unattended in mountainous areas during the summer season. Wolverines Gulo gulo re-established in the alpine regions of southern Norway during recent decades and are viewed as a substantial predator on lambs. Reducing predation on sheep by wolverines would...

  19. Protecting egg prey from Carrion Crows: the potential of aversive conditioning

    Contributor(s):: Cox, R., Baker, S. E., Macdonald, D. W., Berdoy, M.

    Carrion Crows, Corvus corone, are held responsible for taking the eggs and chicks of many bird species. In areas of conservation significance, intervention may be required. Traditionally, managers have attempted to control predation by killing predators, but this may not be the most effective or...

  20. The impact of anthropogenic factors on the behavior, reproduction, management and welfare of urban, free-roaming cat populations

    Contributor(s):: Finkler, H., Hatna, E., Terkel, J.

    Free-roaming domestic cats constitute an integral part of many urban ecosystems worldwide; their presence results from undisturbed natural reproduction, abandonment by pet owners, and abundant food resources. These cats present controversial and emotional issues regarding management of their high...
