  1. The role of genes, epigenetics and ontogeny in behavioural development

    Contributor(s):: Rodenburg, T. Bas

    This review focuses on the role of genes, epigenetics and ontogeny in behavioural development of animals. The behavioural characteristics of an individual are determined by its genes and by its physical and social environment. Not only the individual's early life and current environment are of...

  2. Evolution of facial muscle anatomy in dogs

    Contributor(s):: Kaminski, J., Waller, B. M., Diogo, R., Hartstone-Rose, A., Burrows, A. M.

    Domestication shaped wolves into dogs and transformed both their behavior and their anatomy. Here we show that, in only 33,000 y, domestication transformed the facial muscle anatomy of dogs specifically for facial communication with humans. Based on dissections of dog and wolf heads, we show that...

  3. Family Dog Project: history and future of the ethological approach to human-dog interaction

    Contributor(s):: Abdai, J., Miklosi, A.

    Dogs occupy a specific niche in the human social environment. Some authors argued that dogs' social competence show functional similarities in their components (e.g. attachment, rule following) to that of humans due to their long history living in anthropogenic environment if proper socialisation...

  4. Long-term effects of straw blocks in pens with finishing pigs and the interaction with boar type

    Contributor(s):: Bulens, Anneleen, Van Beirendonck, Sanne, Van Thielen, Jos, Buys, Nadine, Driessen, Bert

    This study verified the effect of straw blocks on the behavior and growth of finishing pigs and possible interactions with the genetic background (boar type). A total of 359 finishing pigs, which were offspring from different boar types, were housed in gender-mixed pens with slatted floors. Half...

  5. Overview and critique of stages and periods in canine development

    Contributor(s):: Fox, M. W.

  6. The truth about cats and dogs: Are there genetic influences on pet ownership

    Contributor(s):: Spotts, Erica L., Lichtenstein, Paul, Neiderhiser, Jenae M.

  7. Environmental enrichment exerts anxiolytic effects in the Indian field mouse (Mus booduga)

    Contributor(s):: Varman, D. R., Ganapathy, Marimuthu, Rajan, K. E.

  8. Human perceptions of coat color as an indicator of domestic cat personality

    Contributor(s):: Delgado, M. M., Munera, J. D., Reevy, G. M.

  9. Film commentary: Constitutional and Environmental Interactions in Rearing Four Breeds of Dogs

    Contributor(s):: Scott, John Paul

  10. Behavior Genetics of Canine Aggression: Behavioral Phenotyping of Golden Retrievers by Means of an Aggression Test

    Contributor(s):: van den Berg, L., Schilder, M. B. H., Knol, B. W.

  11. Primate models in serotonin transporter research

    Contributor(s):: Herman, Khalisa N., Winslow, James T., Suomi, Stephen J.

  12. A behaviour test on German Shepherd dogs: heritability of seven different traits

    Contributor(s):: Ruefenacht, S., Gebhardt-Henrich, S., Miyake, T., Gaillard, C.

    In this study, genetic and non-genetic effects on behavioural traits were estimated, based on records of the field behaviour test of the Swiss German Shepherd Dog breeding club. This standardized test has been applied since 1949 and comprised the following seven traits: self-confidence, nerve...

  13. All a mother's fault? Transmission of stereotypy in striped mice Rhabdomys

    Contributor(s):: Jones, M., Lierop, M. van, Pillay, N.

    Environmentally induced stereotypy is the most common abnormal behaviour in captive animals. However, not all animals housed in identically impoverished environments develop stereotypy, possibly because of differences in genetic predisposition. To investigate the transmission of stereotypy in...

  14. Effect of male-to-male aggressiveness and feed-restriction during rearing on sexual behaviour and aggressiveness towards females by male domestic fowl

    Contributor(s):: Millman, S. T., Duncan, I. J. H.

    This experiment was one part of a larger study investigating problems of aggression towards females by male broiler breeder fowl. To investigate causal mechanisms, we were interested in determining (1) if feed-restriction during rearing affects behaviour towards females at sexual maturity and (2)...

  15. Genetic analysis of reactivity to humans in Goettingen minipigs

    Contributor(s):: Kohn, F., Sharifi, A. R., Simianer, H.

    Goettingen minipigs are laboratory animals with an increasing demand over the last few years. At the moment, Goettingen minipigs are not selected for a low reactivity to humans and this trait is not included in the breeding programme. However, it is obvious that there is a need for genetically...

  16. Increased reproductive output in stereotypic captive Rhabdomys females: potential implications for captive breeding

    Contributor(s):: Jones, M. A., Lierop, M. van, Mason, G., Pillay, N.

    Captive animal populations can diverge considerably from populations in the wild, despite the animals not being deliberately domesticated. If the phenotypes which are of benefit in captivity are heritable, the genotypes of captive-stock can diverge swiftly and substantially from wild-stock. Using...

  17. Indication of a genetic basis of stereotypies in laboratory-bred bank voles ( Clethrionomys glareolus )

    Contributor(s):: Schoenecker, B., Heller, K. E.

    The development of stereotypies was studied in 2 successive laboratory-bred generations of bank voles representing F1 (n=248) and F2 (n=270) of an originally wild caught stock. It was shown that the propensity to develop stereotypies under barren housing conditions strongly relates to the same...

  18. Influence of maternal experience on fear reactions in ewes

    Contributor(s):: Vierin, M., Bouissou, M. F.

    The effects of maternal experience on fearfulness were assessed in ewes by comparing fear reactions of nulliparous (21 months old; N=19), primiparous (21 months old, one lamb reared; N=27) and multiparous (mean age: 4.5+or-1.2 years; one to four litters reared; N=17) Ile-de-France ewes. All ewes...

  19. Influence of mothering on emotional and social reactivity of domestic pullets

    Contributor(s):: Perre, Y., Wauters, A. M., Richard-Yris, M. A.

    The aim of this study was to determine whether different early mothering experiences influenced emotional and social reactivity of sub-adults and adults in domestic fowl. We compared two types of individuals: brooded and non-brooded pullets. Brooded pullets were reared by a maternal hen during...

  20. Investigations on genetic disease resistance in swine - a contribution to the reduction of pain, suffering and damage in farm animals. (Special Issue: Animal suffering and welfare.)

    Contributor(s):: Reiner, G.

    This review deals with genetic disease resistance in pigs as a prospective opportunity to reduce pain, suffering and damage in swine production. Even under favourable terms of housing and management, infectious diseases are wide-spread, and have to be ranked among the major sources for suffering...
