  1. A note on the effect of controlling stable flies ( Stomxys calcitrans ) in the resting activity and pen distribution of dairy cows

    Contributor(s):: Vitela, I., Cruz-Vazquez, C., Orihuela, A.

    This study investigated the effect of controlling stable flies (Stomoxys calcitrans) on the number of dairy cows lying down and their pen distribution. The study randomly assigned 80 Holstein cows to 1 of 2 groups. The treated group (T) included cows individually sprayed with insecticide when...

  2. A review of mulesing and other methods to control flystrike (cutaneous myiasis) in sheep

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

    Flystrike (cutaneous myiasis) in sheep has the potential to have a major impact on the welfare of significant numbers of sheep worldwide, but particularly in Australia. The main control method used in Australia, the mulesing operation to remove folds of skin from the hindquarters of the sheep, is...

  3. A survey of canine heartworm awareness in Grenada, West Indies

    Contributor(s):: Lohmann, S., Sage, S., Stone, D., Gibson, K.

    Heartworm is a common parasite of dogs in Grenada, West Indies, due to the tropical climate and large number of mosquitoes. Because Grenada is a developing country and a small island, resources and education on heartworm are limited. In an effort to raise awareness of canine heartworm and the...

  4. Agricultural practices, ecology and ethics in the Third World

    Contributor(s):: Westra, L. S., Bowen, K. L., Behe, B. K.

    The increasing demand for horticultural products for nutritional and economic purposes by lesser developed countries (LDCs) is well documented. Technological demands of the LDCs producing horticultural products are also increasing. Pesticide use is an integral component of most agricultural...

  5. Altered aggression in different sized groups of crayfish supports a dynamic social behaviour model

    Contributor(s):: Patullo, B. W., Baird, H. P., Macmillan, D. L.

    Living in groups with conspecifics can increase an animal's fitness in the wild. A social environment may also be imposed by commercial farming industries. One important measure of competition and group dynamics is the level of aggressive interaction. This can also influence the level of damage...

  6. Animal behaviour, animal welfare and the scientific study of affect. (Special Issue: Animal suffering and welfare.)

    Contributor(s):: Fraser, D.

    Many questions about animal welfare involve the affective states of animals (pain, fear, distress) and people look to science to clarify these issues as a basis for practices, policies and standards. However, the science of the mid twentieth century tended to be silent on matters of animal affect...

  7. Animals and Us

    Contributor(s):: Harold Herzog

    Animals and Us focuses on the psychology and ethics of our relationships with members of other species.

  8. Around cats

    Contributor(s):: Goldstein, E. J. C., Greene, C. E., Schlossberg, D.

    This chapter focuses on diseases transmitted from cats to humans. The diseases transmitted by inhalation (bordetellosis, plague and Q fever), vectors (ehrlichiosis, anaplasmosis, cat scratch disease, bacillary angiomatosis, flea-borne spotted fever, murine typhus and leishmaniasis), faecal-oral...

  9. Attitudes toward animals: a study of Portuguese children

    Contributor(s):: Almeida, A., Vasconcelos, C., Strecht-Ribeiro, O.

    In this study we analyzed the attitudes toward different animals in 210 Portuguese children: 107 boys and 103 girls, aged between 8 and 10 years, attending the 3rd and 4th years of primary school. We used a questionnaire with two distinct parts. In the first part, the children were asked about...

  10. Barriers to Live Animal Handling Training for Zoo Volunteers

    Contributor(s):: Susanne C. Tygielski

    Zoos and museums utilize docents, or volunteer educators, to help educate and entertain visitors through live animal demonstrations. Preparing volunteers to handle live animals is complex because volunteers must learn animal handling techniques, emergency protocols, interpretive material, be able...

  11. Bees making art: insect aesthetics and the ecological moment

    Contributor(s):: Kosut, M., Moore, L. J.

  12. Behavior of grazing cattle exposed to small populations of stable flies ( Stomoxys calcitrans L.)

    Contributor(s):: Dougherty, C. T., Knapp, F. W., Burrus, P. B., Willis, D. C., Cornelius, P. L.

    The authors hypothesized that cattle grazing in the presence of low-level infections of stable flies may offset reductions of grazing time by increasing their rate of herbage intake, and that this may contribute to the determination of economic threshold populations. On 4 consecutive days, 4...

  13. Behaviour of juvenile mud crabs Scylla serrata in aquaculture: response to odours of moulting or injured crabs

    | Contributor(s):: Wall, D., Paterson, B., Mohan, R.

    Behaviour of juvenile mud crabs, Scylla serrata (70–90 mm carapace width, CW) were observed in response to odours of moulting and injured conspecifics and food (pilchard) under controlled flow conditions using bioassay technique. This study was undertaken to better...

  14. Bugging the strict vegan

    | Contributor(s):: Fischer, B.

    Entomophagy-eating insects-is getting a lot of attention these days. However, strict vegans are often uncomfortable with entomophagy based on some version of the precautionary principle: if you aren't sure that a being isn't sentient, then you should treat it as though it is. But not only do...

  15. Cannibalism in juvenile blue-swimmer crabs Portunus pelagicus (Linnaeus, 1766): effects of body size, moult stage and refuge availability

    | Contributor(s):: Marshall, S., Warburton, K., Paterson, B., Mann, D.

    Factors influencing the rate of cannibalism in juvenile blue-swimmer crabs Portunus pelagicus were investigated under controlled conditions using time-lapse video recordings. This study was undertaken to improve blue-swimmer crab culture and experimentally addressed (1) prey vulnerability (2)...

  16. Cat, dog and house dust mite allergen levels on children's soft toys

    | Contributor(s):: Wu, FuSheng, Wu, MeiWen, Ting, MingHui, Crane, J., Siebers, R.

    Objective: Children's soft toys are known to harbour house dust mite (HDM) allergens, but little is known whether they harbour cat or dog allergens. The objective of the study was to measure cat (Fel d 1), dog (Can f 1) and HDM allergens on children's soft toys. Methods: Dust was collected from...

  17. Changes in the contents of adenine nucleotides and intermediates of glycolysis and the citric acid cycle in flight muscle of the locust upon flight and their relationship to the control of the cycle

    | Contributor(s):: Rowan, A. N., Newsholme, E. A.

  18. Charismatic krill? Size and conservation in the ocean

    | Contributor(s):: Leane, E., Nicol, S.

    The open ocean is an alien place for human beings and for most of history it has been studied using very indirect means. A great deal of what we know about animals that live on land, from ants to elephants, is based on centuries of direct natural history observations of animals alive and in situ....

  19. Claw removal and feeding ability in the edible crab, Cancer pagurus : implications for fishery practice

    | Contributor(s):: Patterson, L., Dick, J. T. A., Elwood, R. W.

    Feeding ability and motivation were assessed in the edible crab, Cancer pagurus, to investigate how the fishery practice of de-clawing may affect live crabs returned to the sea. Crabs were either induced to autotomise one claw, or were only handled, before they were offered food. Initially,...

  20. Conservation of biodiversity within Canadian agricultural landscapes: integrating habitat for wildlife

    | Contributor(s):: Mineau, P., McLaughlin, A.

    Industrialized agriculture currently substitutes for many of the ecological functions of soil microorganisms, macroinvertebrates, wild plants, and vertebrate animals with high cost inputs of pesticides and fertilizers. Enhanced biological diversity potentially offers agricultural producers a...
