    | Contributor(s):: Jim McGetrick, Lisa Poncet, Marietta Amann, Johannes Schullern- Schrattenhofen, Leona Fux, Mayte Martinez, Friederike Range

    Domestic dogs have been shown to reciprocate help received from conspecifics in food-giving tasks. However, it is not yet known whether dogs also reciprocate help received from humans. Here, we investigated whether dogs reciprocate the receipt of food from humans. In an experience phase,...

  2. Aspects of juvenile and adolescent environment predict aggression and fear in 12-month-old guide dogs

    Full-text: Available

    | Contributor(s):: Serpell, J. A., Duffy, D. L.

    Maturational changes in behavior, and the possible influence of the puppy-raising environment on behavioral development, were investigated in a total sample of 978 prospective guide dogs belonging to four different breeds/crosses. All dogs belonged to the same guide dog organization, and had...

  3. How much confidence do we need in animal experiments? Statistical assumptions in sample size estimation

    | Contributor(s):: Richter, Veronika, Muche, Rainer, Mayer, Benjamin

    Statistical sample size calculation is a crucial part of planning nonhuman animal experiments in basic medical research. The 3R principle intends to reduce the number of animals to a sufficient minimum. When planning experiments, one may consider the impact of less rigorous assumptions during...

  4. Detecting autocorrelation problems from GPS collar data in livestock studies

    | Contributor(s):: Perotto-Baldivieso, Humberto Lauro, Cooper, Susan Margaret, Cibils, Andrés Francisco, Figueroa-Pagán, Manuel, Udaeta, Karen, Black-Rubio, Christina Michelle

    Uneven use of grasslands and savannas by livestock has a significant impact on ecosystem productivity, biodiversity, and function. In studies of livestock distribution, global positioning systems (GPS) collars are frequently used and the rapid rate of technological improvement has brought new...

  6. Effects of size distribution on social interactions and growth of juvenile black rockfish (Sebastes schlegelii)

    | Contributor(s):: Guo, Haoyu, Zhang, Xiumei, Johnsson, Jörgen I.

    Growth heterogeneity in rearing groups may complicate feeding operations and inducing cannibalism in cultured fish. To reduce these problems size grading has become a common rearing practice. To better understand the relationship between size grading and growth variation in cultured juvenile...

  11. Learning arithmetic outdoors in junior high school – influence on performance and self-regulating skills

    | Contributor(s):: Emilia Fägerstam, Joakim Samuelsson

    This study aims to explore the influence of outdoor teaching among students, aged 13, on arithmetic performance and self-regulation skills as previous research concerning outdoor mathematics learning is limited. This study had a quasi-experimental design. An outdoor and a traditional group...

  12. Pet dog management practices among a representative sample of owners in Victoria, Australia

    | Contributor(s):: Howell, T. J., Mornement, K., Bennett, P. C.

    It is often assumed that pet dogs experience better welfare than livestock production animals because many owners consider them to be members of the family and, collectively, spend billions of dollars on them annually. However, this assumption is not based on scientific evidence, and a...

  13. Behavioral ecology of captive species: using bibliographic information to assess pet suitability of mammal species

    | Contributor(s):: Koene, P., Mol, R. M. de, Ipema, B.

    Which mammal species are suitable to be kept as pet? For answering this question many factors have to be considered. Animals have many adaptations to their natural environment in which they have evolved that may cause adaptation problems and/or risks in captivity. Problems may be visible in...

  14. Influences on the avoidance and approach behaviour of dairy goats towards an unfamiliar human - an on-farm study

    | Contributor(s):: Mersmann, D., Schmied-Wagner, C., Nordmann, E., Graml, C., Waiblinger, S.

    The human-animal relationship (HAR) is an important factor for successful animal husbandry and animal welfare. Thus, the HAR is included in on-farm assessments to evaluate overall welfare. For dairy goats, validated tests to assess the HAR are lacking. The aim of the present study was to evaluate...

  15. Do all dogs go to heaven? Investigating the association between demographic characteristics and beliefs about animal afterlife

    | Contributor(s):: Royal, K. D., Kedrowicz, A. A., Snyder, A. M.

    The purpose of this research was to explore American's beliefs about animal afterlife based on key demographic factors such as sex, race/ethnicity, age, geographic region, religion/faith, and pet ownership. We attained a large and diverse sample of respondents (n=800) using Amazon's Mechanical...

  16. A simulation study of the effect of therapeutic horseback riding : a logistic regression approach

    | Contributor(s):: Jeanette Pauw

    Therapeutic horseback riding (THR) uses the horse as a therapeutic apparatus in physical and psychological therapy. This dissertation suggests a more appropriate technique for measuring the effect of THR. A research survey of the statistical methods used to determine the effect of THR was...
