  3. Who Do Parrots Talk To? Agreeableness and a Serious Approach Increase the Production of Word-like Utterances by African Grey Parrots

    Full-text: Available

    Contributor(s):: Jitka Lindova°

    Label acquisition projects with the grey parrot (Psittacus erithacus) demonstrated cognitive and communicative skills of this species comparable to great apes. However, results differ profoundly between individuals and laboratories. Two studies investigated the relationship between the...

  4. Shedding light into the dark: Age and light shape nocturnal activity and sleep behaviour of giraffe

    Contributor(s):: Burger, Anna Lena, Hartig, Johannes, Dierkes, Paul W.

    The interaction of internal clocks and environmental conditions determines the daily behavioural rhythm of an animal. Due to the strong influence of light, these circadian rhythms oscillate in mammals over a cycle length of about 24 h, equivalent to the daily light-dark cycle. The relation...

  5. Factors Influencing Time to Adoption for Dogs in a Provincial Shelter System in Canada

    Contributor(s):: Kay, Aileigh, Coe, Jason B., Young, Ian, Pearl, David

    Millions of companion animals are relinquished to shelters each year. For each dog entering, their characteristics and the characteristics of the shelter holding him/her influence their time to adoption. Using a Cox proportional hazards frailty model, these issues were explored using data from 31...

  6. Experimental Control for the Ovariectomized Rat Model: Use of Sham Versus Nonmanipulated Animal

    Contributor(s):: Kruger, Marlena C., Morel, Patrick C. H.

    One of 2 models required by the U.S. Food and Drug Administration for registration of a treatment for osteoporosis, the ovariectomized (OVX) rat model, is widely used in scientific studies investigating sex hormone-deficient bone loss. The use of control nonhuman animals is critical because bone...

  7. Analysis of Dog Adoption Success and Failure Using Surveys With Vignettes

    Contributor(s):: Hill, Stephen E., Murphy, Nancy C.

    Adoption success of dogs who serve as companion animals was analyzed via surveys with vignettes. The researchers administered surveys with vignettes to animal shelter employees, veterinarians, and other animal-care professionals in Eastern North Carolina. Logistic and linear regression analyses...

  8. Human-Insect Relationships: An ANTless Story? Children's, Adolescents', and Young Adults' Ways of Characterizing Social Insects

    Contributor(s):: Sammet, Rebecca, Andres, Heike, Dreesmann, Daniel

    Ants may serve as powerful model organisms for uncovering principles of insect biology and social behavior. The aim of this study was to provide a quantitative analysis of secondary-school students' perceptions and knowledge of ants. It was part of a longitudinal project based on the concept of...

  9. Visual conspecific cues will not help in pygmy bluetongue lizard translocations

    Contributor(s):: Ebrahimi, Mehregan, Bull, C. Michael

    Where a translocation program is used to reinforce an existing population of an endangered species, the response of the introduced individuals to cues from conspecific residents will have an important impact on the success of the translocation. If those cues induce the translocated individuals to...

  10. Methods for cross point analysis of double-demand functions in assessing animal preferences

    Contributor(s):: Engel, Bas, Webb, Laura E., Jensen, Margit Bak, van Reenen, Cornelis G., Bokkers, Eddie A. M.

    Cross point analysis of double demand functions provides a compelling way to quantify the strength of animal preferences for two simultaneously presented resources. During daily sessions, animals have to work to gain access to (a portion of) either resource, e.g. by pressing one of two panels a...

  11. Flocking for food or flockmates?

    Contributor(s):: Asher, Lucy, Collins, Lisa M., Pfeiffer, Dirk U., Nicol, Christine J.

    Animals in groups behave cohesively, even when those animals are domesticated and are housed in limited environments. But how is such group cohesion maintained? Do animals move in an independent manner, according to their own motivations, or in a social manner, with respect to the movements of...

  12. Biology, behavior, and environmental enrichment for the captive African clawed frog (Xenopus spp)

    Contributor(s):: Chum, Helen, Felt, Stephen, Garner, Joseph, Green, Sherril

    Xenopus are a hardy, long-lived, aquatic amphibian species which readily adapt to a captive environment. This characteristic makes Xenopus ideal for the laboratory, where they are used extensively in basic and biomedical research. Though husbandry practices for Xenopus have not been standardized,...

  13. The Frequencies of Immunosuppressive Cells in Adipose Tissue Differ in Human, Non-human Primate, and Mouse Models

    Contributor(s):: Laparra, A., Tricot, S., Le Van, M., Damouche, A., Gorwood, J., Vaslin, B., Favier, B., Benoist, S., Ho Tsong Fang, R., Bosquet, N., Le Grand, R., Chapon, C., Lambotte, O., Bourgeois, C.

  14. Use of social network analysis to improve the understanding of social behaviour in dairy cattle and its impact on disease transmission

    Contributor(s):: de Freslon, Inès, Martínez-López, Beatriz, Belkhiria, Jaber, Strappini, Ana, Monti, Gustavo

    A better comprehension of cattle contact structure can enhance the prevention of the transmission of infectious agents within livestock farms. Social network analysis has proven to provide a more accurate picture of social structures than traditional methods. In this study, we focused on...

  15. A comparison of inferential analysis methods for multilevel studies: Implications for drawing conclusions in animal welfare science

    Contributor(s):: Stevens, Kara N., Asher, Lucy, Griffin, Kym, Friel, Mary, O'Connell, Niamh, Collins, Lisa M.

    Investigations comparing the behaviour and welfare of animals in different environments have led to mixed and often conflicting results. These could arise from genuine differences in welfare, poor validity of indicators, low statistical power, publication bias, or inappropriate statistical...

  16. Agent-based modelling in applied ethology: An exploratory case study of behavioural dynamics in tail biting in pigs

    Contributor(s):: Boumans, Iris J. M. M., Hofstede, Gert Jan, Bolhuis, J. Elizabeth, de Boer, Imke J. M., Bokkers, Eddie A. M.

    Understanding behavioural dynamics in pigs is important to assess pig welfare in current intensive pig production systems. Agent-based modelling (ABM) is an approach to gain insight into behavioural dynamics in pigs, but its use in applied ethology and animal welfare science has been limited so...
