  1. Oxytocin Receptor Gene Polymorphisms Are Associated with Human Directed Social Behavior in Dogs (Canis familiaris)

    Full-text: Available

    | Contributor(s):: Anna Kis, Melinda Bence, Gabriella Lakatos, Enikõ Pergel, Borbála Turcsán, Jolanda Pluijmakers, Judit Vas, Zsuzsanna Elek, Ildikó Brúder, Levente Földi, Mária Sasvári-Székely, Adám Miklósi, Zsolt Rónai, Enikõ Kubinyi

    The oxytocin system has a crucial role in human sociality; several results prove that polymorphisms of the oxytocin receptor gene are related to complex social behaviors in humans. Dogs' parallel evolution with humans and their adaptation to the human environment has made them a useful...

  2. Structural variants in genes associated with human Williams-Beuren syndrome underlie stereotypical hypersociability in domestic dogs

    | Contributor(s):: Bridgett M. vonHoldt, Emily Shuldiner, Ilana Janowitz Koch, Rebecca Y. Kartzinel, Andrew Hogan, Lauren Brubaker, Shelby Wanser, Daniel Stahler, Clive D. L. Wynne, Elaine A. Ostrander, Janet S. Sinsheimer, Monique A. R. Udell

    Although considerable progress has been made in understanding the genetic basis of morphologic traits (for example, body size and coat color) in dogs and wolves, the genetic basis of their behavioral divergence is poorly understood. An integrative approach using both behavioral and genetic data...

  4. Blockade of histone deacetylation in the brain modulates the expression of transcription factors c-FOS and ZENK and potentiates the formation of long-term memory in neonatal chicks

    | Contributor(s):: Toporova, K. A., Anokhin, K. V., Tiunova, A. A.

  5. A standardized ethogram for the Felidae: a tool for behavioral researchers

    | Contributor(s):: Stanton, L. A., Sullivan, M. S., Fazio, J. M.

    Standardized ethograms offer many practical benefits to behavioral researchers, and several examples exist today for various species and taxa. Despite historic evidence that suggests the family Felidae share similar behavioral repertoires, no standardized ethogram providing comprehensive...

  6. Dominance rank is associated with body condition in outdoor-living domestic horses ( Equus caballus)

    | Contributor(s):: Giles, S. L., Nicol, C. J., Harris, P. A., Rands, S. A.

    The aim of our study was to explore the association between dominance rank and body condition in outdoor group-living domestic horses, Equus caballus. Social interactions were recorded using a video camera during a feeding test, applied to 203 horses in 42 herds. Dominance rank was assigned to...

  7. Canine olfactory receptor gene polymorphism and its relation to odor detection performance by sniffer dogs

    | Contributor(s):: Lesniak, A., Walczak, M., Jezierski, T., Sacharczuk, M., Gawkowski, M., Jaszczak, K.

  8. Gut microbiota of humans, dogs and cats: current knowledge and future opportunities and challenges

    | Contributor(s):: Deng, P., Swanson, K. S.

    High-throughput DNA sequencing techniques allow for the identification and characterisation of microbes and their genes (microbiome). Using these new techniques, microbial populations in several niches of the human body, including the oral and nasal cavities, skin, urogenital tract and...

  9. Canine olfactory receptor gene polymorphism and its relation to odor detection performance by sniffer dogs

    | Contributor(s):: Lesniak, A., Walczak, M., Jezierski, T., Sacharczuk, M., Gawkowski, M., Jaszczak, K.

  10. Differences in open field behavior between heterozygous and homozygous negative gilts for the RYR(1) gene

    | Contributor(s):: Fabrega, E., Diestre, A., Font, J., Carrion, D., Velarde, A., Ruiz-de-la-Torre, J. L., Manteca, X.

    A test widely used to assess fear and novelty responses in domestic species is the open field. The aim of this study was to investigate the effect of RYR(1) genotype on open field behavior in growing pigs. The study subjected 15 heterozygous (Nn) and 15 RYR(1)-free (NN) gilts of 19 weeks of age...

  11. Purebred dogs and canine wellbeing

    | Contributor(s):: Jeppsson, S.

    Breeders of purebred dogs usually have several goals they want to accomplish, of which canine wellbeing is one. The purpose of this article is to investigate what we ought to do given this goal. Breeders typically think that they fulfil their wellbeing-related duties by doing the best they can...

  12. Variation in reproductive traits of members of the genus Canis with special attention to the domestic dog ( Canis familiaris)

    | Contributor(s):: Lord, K., Feinstein, M., Smith, B., Coppinger, R.

  13. Mycobacterium tuberculosis transmission from human to canine

    A 71-year-old woman from Tennessee, USA with a 3-week history of a productive, nonbloody cough was evaluated. Chest radiograph showed infiltrates and atelectasis in the upper lobe of the right lung. A tuberculosis (TB) skin test resulted in a 14-mm area of induration. Sputum stained positive for...
