  • Apes have culture but may not know that they do 

    Gruber, Thibaud; Zuberbuehler, Klaus; Clement, Fabrice; van Schaik, Carel (2015-02-06) - Journal article
    There is good evidence that some ape behaviors can be transmitted socially and that this can lead to group-specific traditions. However, many consider animal traditions, including those in great apes, to be fundamentally ...
  • Asymmetric distribution of pl10 and bruno2, new members of a conserved core of early germline determinants in cephalochordates 

    Dailey, Simon Christopher; Planas, Roser Febrero; Espier, Adriana Rossell; Garcia-Fernandez, Jordi; Somorjai, Ildiko Maureen Lara (2016-01-22) - Journal article
    Molecular fingerprinting of conserved germline and somatic ¨stemness¨ markers in different taxa have been key in defining the mechanism of germline specification ("preformation" or "epigenesis"), as well as expression ...

    Woodman, Andrew; Arnold, Jamie; Cameron, Craig; Evans, David John (2016-08-19) - Journal article
    Genetic recombination in single-strand, positive-sense RNA viruses is a poorly understand mechanism responsible for generating extensive genetic change and novel phenotypes. By moving a critical cis-acting replication ...
  • Burkholderia pseudomallei genome plasticity associated with genomic island variation 

    Tumapa, Sarinna; Holden, Matthew T. G.; Vesaratchavest, Mongkol; Wuthiekanun, Vanaporn; Limmathurotsakul, Direk; Chierakul, Wirongrong; Feil, Edward J.; Currie, Bart J.; Day, Nicholas P. J.; Nierman, William C.; Peacock, Sharon J. (2008-04-25) - Journal article
    Background: Burkholderia pseudomallei is a soil-dwelling saprophyte and the cause of melioidosis. Horizontal gene transfer contributes to the genetic diversity of this pathogen and may be an important determinant of virulence ...
  • Changes in women's facial skin color over the ovulatory cycle are not detectable by the human visual system 

    Burriss, Robert P.; Troscianko, Jolyon; Lovell, P. George; Fulford, Anthony J. C.; Stevens, Martin; Quigley, Rachael; Payne, Jenny; Saxton, Tamsin K.; Rowland, Hannah M. (2015-07-02) - Journal article
    Human ovulation is not advertised, as it is in several primate species, by conspicuous sexual swellings. However, there is increasing evidence that the attractiveness of women's body odor, voice, and facial appearance peak ...
  • Chimpanzee lip-smacking facilitates cooperative behaviour 

    Fedurek, Pawel; Slocombe, Katie; Hartel, Jessica A.; Zuberbuehler, Klaus (2015-08-21) - Journal article
    Signalling plays an important role in facilitating and maintaining affiliative or cooperative interactions in social animals. Social grooming in primates is an example of an interaction that requires coordination between ...
  • Comparative genomics of vancomycin-resistant Staphylococcus aureus strains and their positions within the clade most commonly associated with methicillin-resistant S. aureus hospital-acquired infection in the United States 

    Kos, Veronica N.; Desjardins, Christopher A.; Griggs, Allison; Cerqueira, Gustavo; Van Tonder, Andries; Holden, Matthew T. G.; Godfrey, Paul; Palmer, Kelli L.; Bodi, Kip; Mongodin, Emmanuel F.; Wortman, Jennifer; Feldgarden, Michael; Lawley, Trevor; Gill, Steven R.; Haas, Brian J.; Birren, Bruce; Gilmore, Michael S. (2012-05-22) - Journal article
    Methicillin-resistant Staphylococcus aureus (MRSA) strains are leading causes of hospital-acquired infections in the United States, and clonal cluster 5 (CC5) is the predominant lineage responsible for these infections. ...
  • A comparative investigation of the cognitive and social factors underlying a capacity for cumulative culture 

    Dean, Lewis G. (University of St Andrews, 2011-07-22) - Thesis
    Human culture has been proposed to uniquely exhibit a ‘ratchet effect’, with beneficial modifications being made to cultural traits over many generations. This is widely thought to have allowed an accumulation of technology ...
  • Comparing the performances of apes (Gorilla gorilla, Pan troglodytes, Pongo pygmaeus) and human children (Homo sapiens) in the floating peanut task 

    Hanus, Daniel; Mendes, Natacha; Tennie, Claudio; Call, Josep (2011-06-08) - Journal article
    Recently, Mendes et al. [1] described the use of a liquid tool (water) in captive orangutans. Here, we tested chimpanzees and gorillas for the first time with the same "floating peanut task." None of the subjects solved ...
  • Complex patterns of signalling to convey different social goals of sex in bonobos, Pan paniscus 

    Genty, Emilie; Neumann, Christof; Zuberbuehler, Klaus (2015-11-05) - Journal article
    Sexual behaviour in bonobos (Pan paniscus) functions beyond mere reproduction to mediate social interactions and relationships. In this study, we assessed the signalling behaviour in relation to four social goals of sex ...
  • Continental growth and the crustal record 

    Hawkesworth, Chris; Cawood, Peter; Dhuime, Bruno (2013-12-08) - Journal item
    The continental crust is the archive of Earth history. The spatial and temporal distribution of the Earth's record of rock units and events is heterogeneous with distinctive peaks and troughs in the distribution of ages ...
  • Creating S0s with major mergers : a 3D view 

    Querejeta, Miguel; Eliche-Moral, M. Carmen; Tapia, Trinidad; Borlaff, Alejandro; van de Ven, Glenn; Lyubenova, Mariya; Martig, Marie; Falcón-Barroso, Jesús; Mendez-Abreu, Jairo; Zamorano, Jaime; Gallego, Jesús (2015-12-03) - Journal article
    A number of simulators have argued that major mergers can sometimes preserve discs, but the possibility that they could explain the emergence of lenticular galaxies (S0s) has been generally neglected. In fact, observations ...
  • CRISPR interference : a structural perspective 

    Reeks, Judith Anne; Naismith, Jim; White, Malcolm F (2013-06) - Journal item
    CRISPR (cluster of regularly interspaced palindromic repeats) is a prokaryotic adaptive defence system, providing immunity against mobile genetic elements such as viruses. Genomically encoded crRNA (CRISPR RNA) is used by ...
  • Culture and social learning in chimpanzees (Pan troglodytes) and children (Homo sapiens) 

    Spiteri, Anthony (University of St Andrews, 2009-06-24) - Thesis
    Culture involves the handing down of information, traditions, knowledge and skill, views and ideals from one individual to another and across generations by means of social transmission expressed in manufactured objects ...
  • The desaturase gene family : an evolutionary study of putative speciation genes in 12 species of Drosophila 

    Keays, Maria C. (University of St Andrews, 2011-11-30) - Thesis
    The formation and persistence of species are the subject of much debate among biologists. Many species of Drosophila are behaviourally isolated, meaning that heterospecific individuals are not attracted to one another and ...

    The star 1SWASP J024743.37-251549.2 was recently discovered to be a binary star in which an A-type dwarf star eclipses the remnant of a disrupted red giant star (WASP 0247-25 B). The remnant is in a rarely observed state ...
  • Ellipsoidal vortices in rotating stratified fluids : beyond the quasi-geostrophic approximation 

    Tsang, Yue-Kin; Dritschel, David G. (2015-01) - Journal article
    We examine the basic properties and stability of isolated vortices having uniform potential vorticity (PV) in a non-hydrostatic rotating stratified fluid, under the Boussinesq approximation. For simplicity, we consider a ...
  • The evolution of behaviour : a genetic approach 

    Parker, Darren J. (University of St Andrews, 2015-06-24) - Thesis
    In this thesis I investigated the genetic basis of several behaviours to answer questions surrounding the evolution and mechanistic basis of behaviour. Firstly, I took a single-gene approach to investigate the influence ...

    Van Der Post, Daniel Job; Verbrugge, Rineke; Hemelrijk, Charlotte (2015-01-28) - Journal article
    Different forms of sociality have evolved via unique evolutionary trajectories. However, it remains unknown to what extent trajectories of social evolution depend on the specific characteristics of different species. Our ...
