    Background: Horizontal gene transfer (HGT) has been suggested as the mechanism by which various plant parasitic nematode species have obtained genes important in parasitism. In particular, cellulase genes have been acquired ...
  • Distribution and evolution of starspots on the RS CVn binary II Pegasi in 2004 

    Xiang, Y.; Gu, S.-H.; Collier Cameron, A.; Barnes, J.R. (2014-03-01) - Journal article
    We present Doppler images of RS CVn-type binary II Peg based on two data sets obtained in 2004 February and November. In order to improve signal-to-noise ratio and reliability,we apply least-squares deconvolution technique ...
  • The distribution and physiological roles of nitric oxide in the locomotor circuitry of the mammalian spinal cord 

    Dunford, Catherine (University of St Andrews, 2012-11-30) - Thesis
    The mammalian spinal cord contains the neuronal circuitry necessary to generate rhythmic locomotor activity in the absence of inputs from the higher brain centre or sensory system. This circuitry is regulated by local ...
  • Distribution ecology of Palearctic migrants in the humid Guinea savannah in West Africa 

    Ivande, Samuel T. (University of St Andrews, 2015-11-30) - Thesis
    Declines in breeding populations of most migrants across much of the Palearctic have been linked to environmental conditions in their African non-breeding grounds. Studying winter distribution dynamics for these species ...
  • Distribution of electric currents in solar active regions 

    Török, T.; Leake, J.E.; Titov, V.S.; Archontis, V.; Mikić, Z.; Linton, M.G.; Dalmasse, K.; Aulanier, G.; Kliem, B. (2014-02-10) - Journal article
    There has been a long-standing debate on the question of whether or not electric currents in solar active regions are neutralized. That is, whether or not the main (or direct) coronal currents connecting the active region ...
  • Distribution of independent components of binocular natural images 

    Hunter, David William; Hibbard, Paul Barry (2015-09) - Journal article
    An influential theory of the function of early processing in the visual cortex is that it forms an efficient coding of ecologically valid stimuli. In particular, correlations and differences between visual signals from the ...
  • The distribution of legal traditions around the world : A contribution to the legal origins theory 

    Oto-Peralías, Daniel; Romero-Ávila, Diego (2014-08) - Journal article
    The distribution of the common law was conditioned by a colonial strategy sensitive to the colonies’ level of endowments, exhibiting a more effective implantation of the legal system in initially sparsely populated territories ...
  • Distribution, abundance, and feeding ecology of baleen whales in Icelandic waters: have recent environmental changes had an effect? 

    Vikingsson, Gisli A; Pike, Daniel G; Valdimarsson, Héðinn; Schleimer, Anna; Gunnlaugsson, Thorvaldur; Silva, Teresa; Elvarsson, Bjarki Þ; Mikkelsen, Bjarni; Øien, Nils; Desportes, Geneviève; Bogason, Valur; Hammond, Philip Steven (2015-02-17) - Journal article
    The location of Iceland at the junction of submarine ridges in the North-East Atlantic where warm and cold water masses meet south of the Arctic Circle contributes to high productivity of the waters around the island. ...

    Servidio, Antonella (University of St Andrews, 2014-06) - Thesis
    The Canary Archipelago is considered one of the planet’s biodiversity hotspots and the short-finned pilot whale is a key species in need of conservation measures. To address a lack of knowledge, almost 2,000 day-surveys ...
