  1. The ecology of unwanted and uncontrolled pets

    Contributor(s):: Beck, A. M.

  2. The law and the pet: a reasonable compromise Dogs, behavior, USA

    Contributor(s):: Beck, A. M.

  3. Four types of activities that affect animals: implications for animal welfare science and animal ethics philosophy

    Contributor(s):: Fraser, D., MacRae, A. M.

    People affect animals through four broad types of activity: (1) people keep companion, farm, laboratory and captive wild animals, often while using them for some purpose; (2) people cause deliberate harm to animals through activities such as slaughter, pest control, hunting, and toxicology...

  4. Rangifer and man: an ancient relationship

    Contributor(s):: Gordon, B.

    A long-term relationship between Rangifer and humans is documented in three case studies: the Canadian Barrenlands (8000 years ago to Historic period), Ice-Age France (11 000-19 000 years ago) and Mesolithic Russia (7000-10 000 years ago). Ancient human and herd migration occurred in all areas,...

  5. Reindeer and caribou ( Rangifer tarandus ) response towards human activities

    Contributor(s):: Reimers, E., Colman, J. E.

    We address the question of how human activities and infrastructure influence reindeer/caribou's (R. tarandus) behaviour and habitat use in Norway and review studies based on current methodologies. Anthropogenic activities have a direct affect on Rangifer behaviour through the senses hearing,...

  6. 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,...

  7. Mating behavior of cockerels: effects of social status, group size and group density

    Contributor(s):: Kratzer, D. D., Craig, J. V.

  8. Effects of intra- and interspecific competition on diet, growth and behaviour of Labeo calbasu (Hamilton) and Cirrhinus cirrhosus (Bloch)

    Contributor(s):: Rahman, M. M., Verdegem, M.

    Effects of intra- and interspecific competition on diet, growth, grazing, swimming, resting and social behaviour of two carps calbasu (Labeo calbasu) and mrigal (Cirrhinus cirrhosus) were examined in single and mixed species treatments. Three treatments (tanks with 4 L. calbasu, 4 C. cirrhosus or...

  9. 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...

  10. 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...

  11. Site use of grazing cattle and sheep in a large-scale pasture landscape: a GPS/GIS assessment

    Contributor(s):: Putfarken, D., Dengler, J., Lehmann, S., Hardtle, W.

    Year-round mixed-species grazing at low densities in large-scale pasture systems has become a popular conservation concept as it is assumed to maintain the valuable biodiversity of semi-open cultural landscapes. This study aims to elucidate which vegetation types are preferentially grazed by...

  12. The feeding pattern of the Norway rat ( Rattus norvegicus ) in two differently structured habitats on a farm

    Contributor(s):: Klemann, N., Pelz, H. J.

    The adaptation of bait uptake behaviour in Norway rats (Rattus norvegicus) to the conditions of particular habitats was investigated on a farm in north-west Germany. Live-trapped rats were fitted with individual PIT tags and were automatically registered at bait stations in two differently...

  13. A note on the use of GPS collars to monitor wild maned wolves Chrysocyon brachyurus (Illiger 1815) (Mammalia, Canidae)

    Contributor(s):: Coelho, C. M., Melo, L. F. B. de, Sabato, M. A. L., Rizel, D. N., Young, R. J.

    Increasingly, problems of animal conservation are being solved with the aid of technology. One recent advance in monitoring the spatial location of wild animals is the GPS collar. In this study we evaluate the use of such technology with three wild maned wolves. In a period of 155 days our three...

  14. Effects of habitat complexity on the aggressive behaviour of the American lobster ( Homarus americanus ) in captivity

    Contributor(s):: Cenni, F., Parisi, G., Gherardi, F.

    The American lobster, Homarus americanus, is one of the most economically valuable crustacean decapods worldwide, being mostly exploited to foster the live animal industry. Lobsters are typically held in storage facilities where individuals may suffer due to the repeated combats among each other....

  15. 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...

  16. Resting or hiding? Why broiler chickens stay near walls and how density affects this

    Contributor(s):: Buijs, S., Keeling, L. J., Vangestel, C., Baert, J., Vangeyte, J., Tuyttens, F. A. M.

    Broiler chickens are reported to be close to walls at higher densities. The reason for this is not clear, since evolutionary theories would suggest that birds should attempt to be in the middle of the flock. We studied the spatial distribution (during weeks 4-6) of broiler chickens stocked at...

  17. Counter-discourses and the relationship between humans and other animals

    Contributor(s):: Stibbe, A.

    Several recent studies have critically analysed discourses involved in the oppression and exploitation of nonhuman animals, including those of the meat industry and zoos. This article turns the spotlight on counter-discourses, such as those of ecology and animal liberation, to ask if the...

  18. Development of an item scale to assess attitudes towards domestic dogs in the United Republic of Tanzania

    Contributor(s):: Knobel, D. L., Laurenson, K. M., Kazwala, R. R., Cleaveland, S.

    Domestic dogs are important sources of rabies exposure for humans in the developing world. Control of the disease in endemic areas relies on the vaccination of owned dogs, and thus owners' attitudes and behaviour towards household dogs may be of relevance to rabies control programmes. However,...

  19. Effects of having pets at home on children's attitudes toward popular and unpopular animals

    Contributor(s):: Prokop, P., Tunnicliffe, S. D.

    Having pets at home provides various social, health, and educational benefits to children. The question of how keeping pets at home affects the attitudes of children toward wild animals still has not been answered, due to various methodological issues, such as ignorance of some attitude...

  20. Haiku and beyond: language, ecology, and reconnection with the natural world

    Contributor(s):: Stibbe, A.

    This article presents a detailed analysis of the representation of animals, plants and nature in Japanese haiku. In haiku, animals and plants are written back into the language, appearing for themselves as manifestations of life deserving of empathy and respect. In this way, haiku encourage...
