  1. Survival, fecundity, and movements of free-roaming cats

    Contributor(s):: Schmidt, P. M., Lopez, R. R., Collier, B. A.

    Free-roaming cats (e.g., owned, semi-feral, and feral) impact wildlife worldwide through predation, competition, and disease transmission. Baseline ecological information necessary for population management is lacking. We radiocollared free-roaming cats (feral, n=30; semi-feral, n=14; owned,...

  2. Developing fish passage and protection at hydropower dams. (Special issue: Fish Behaviour and Welfare.)

    Contributor(s):: Schilt, C. R.

    The development of waterways, for hydropower and other industrial uses, has substantially altered many of the freshwater habitats of the planet and this has had considerable impact upon aquatic organisms. Industrial changes in aquatic ecosystems, including hydropower development, can restrict or...

  3. Feral pigs in Hawai'i: using behavior and ecology to refine control techniques

    Contributor(s):: Nogueira, S. S. da C., Nogueira Filho, S. L. G., Bassford, M., Silvius, K., Fragoso, J. M. V.

    Early Polynesians settlers were the first to introduce pigs to the Hawaiian Islands. Later Captain Cook brought European pigs during his first voyage to Hawai'i. Many other importations have followed. Animals from these introductions became feral and dispersed throughout the islands. Free-ranging...

  4. Quantifying human disturbance on antipredator behavior and flush initiation distance in yellow-bellied marmots

    Contributor(s):: Li, ChunWang, Monclus, R., Maul, T. L., Jiang, ZhiGang, Blumstein, D. T.

    Human disturbance may differentially affect the behavior of wild animals and such behavioral perturbations may have fitness consequences. To understand the effects of specific types of human disturbance on antipredator behavior, a behavior whose performance enhances survival, we studied...

  5. The efficacy of collar-mounted devices in reducing the rate of predation of wildlife by domestic cats

    Contributor(s):: Nelson, S. H., Evans, A. D., Bradbury, R. B.

    Volunteer cat owners from across the UK were recruited to take part in two trials designed to test the efficacy of collar-mounted warning devices in reducing cat predation rates of native wildlife. Cats equipped with a bell returned 34% fewer mammals and 41% fewer birds than those with a plain...

  6. 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...

  7. Animal welfare and pest control: meeting both conservation and animal welfare goals. (Special Issue: Conservation and animal welfare.)

    Contributor(s):: Littin, K. E.

    Vertebrate pest control is an area where conservation and animal welfare goals can be in direct conflict. Is it possible to meet goals in both areas in one pest control operation? Vertebrate pests, including unwanted or overabundant wildlife, are controlled for many reasons related to protecting...

  8. Mammal trapping: a review of animal welfare standards of killing and restraining traps

    Contributor(s):: Iossa, G., Soulsbury, C. D., Harris, S.

    Millions of wild mammals are trapped annually for fur, pest control and wildlife management. Ensuring the welfare of trapped individuals can only be achieved by trapping methods that meet accepted standards of animal welfare. At the international level, the assessment of mechanical properties of...

  9. Trade-offs between welfare, conservation, utility and economics in wildlife management - a review of conflicts, compromises and regulation

    Contributor(s):: Reynolds, J. C.

    In choosing among alternative wildlife management techniques, trade-offs between animal welfare and conservation, utility or economics are often apparent. This paper reviews the roles of science, scientists, regulators and educators in attempts to overcome this inter-dependence and to make...

  10. Countering brutality to wildlife, relationism and ethics: conservation, welfare and the 'ecoversity'. (Special issue: Minding animals: Emerging issues concerning our relationships with other animals.)

    Contributor(s):: Garlick, S., Matthews, J., Carter, J.

    Wildlife objectification and cruelty are everyday aspects of Australian society that eschew values of human kindness, empathy, and an understanding of the uniqueness and importance of non-human life in the natural world. Fostered by institutional failure, greed and selfishness, and the worst...

  11. Population dynamics of mouflon in a protected area of the Italian Alps

    Contributor(s):: Bertolino, S., Hardenberg, A. von, Ribetto, G.
