  • Biodiversity assessment of freshwater fishes : Thailand as a case study 

    Khachonpisitsak, Salinee (University of St Andrews, 2012-11-29) - Thesis
    A key challenge in biodiversity is: How many species are there on earth? This issue is especially acute in poorly surveyed regions with high diversity, particularly Southeast Asia that also experiences many limitations ...
  • Biodiversity of freshwater fishes of Trinidad and Tobago, West Indies 

    Phillip, Dawn Arlene Teresa (University of St Andrews, 1998) - Thesis
    The proximity of the speciose South American continent to Trinidad and Tobago ensures that these islands have a rich and dynamic fauna. According to the equilibrium theory of island biogeography (MacArthur & Wilson ...
  • Biogenesis pathways of RNA guides in archaeal and bacterial CRISPR-Cas adaptive immunity 

    Charpentier, Emmanuelle; Richter, Hagen; van der Oost, John; White, Malcolm F (2015-05-20) - Journal item
    CRISPR-Cas is an RNA-mediated adaptive immune system that defends bacteria and archaea against mobile genetic elements. Short mature CRISPR RNAs (crRNAs) are key elements in the interference step of the immune pathway. A ...

    Carnie, Robert Hay (University of St Andrews, 1954) - Thesis
    The name of Sir David Dalrymple, Lord Hailes has always been known to students of Scottish history by reason of his "Annals of Scotland", long accepted as a fundamental reference book for that period of Scottish history ...
  • The biographical imagination in Moritz's Anton Reiser : a chronotopic reading 

    Cusack, Andrew Thomas (2015-06) - Journal article
  • The biological bases of conformity 

    Morgan, T.J.H.; Laland, K.N. (2012-06-14) - Journal article
    Humans are characterized by an extreme dependence on culturally transmitted information and recent formal theory predicts that natural selection should favor adaptive learning strategies that facilitate effective copying ...
  • Biological diversity of fish communities : pattern and process 

    Magurran, A. E.; Khachonpisitsak, S.; Ahmad, A. B. (2011-12) - Journal article
    For over 150 years, ecologists have been striving to explain fundamental patterns of biological diversity, such as the observation that communities invariably consist of common and rare species, and to unravel the processes ...
  • Biological diversity of freshwater fishes in small streams in peninsular Malaysia 

    Ahmad, Amirrudin Bin (University of St Andrews, 2012) - Thesis
    Peninsular Malaysia has a diverse flora and fauna, much of which is yet to be documented. The freshwater fishes are one important group that have received little attention. Accordingly, the overarching goal of my study ...
  • Biological overlap of attention-deficit/hyperactivity disorder and autism spectrum disorder : evidence from copy number variants 

    Martin, Joanna; Cooper, Miriam; Hamshere, Marian L.; Pocklington, Andrew; Scherer, Stephen W.; Kent, Lindsey; Gill, Michael; Owen, Michael J.; Williams, Nigel; O'Donovan, Michael C.; Thapar, Anita; Holmans, Peter (2014-07) - Journal article
    Objective: Attention-deficit/hyperactivity disorder (ADHD) and autism spectrum disorder (ASD) often co-occur and share genetic risks. The aim of this analysis was to determine more broadly whether ADHD and ASD share ...
  • The biological response of foraminifera to ocean acidification 

    Khanna, Nikki (University of St Andrews, 2014) - Thesis
    Elevated atmospheric concentrations of carbon dioxide (CO₂), partly driven by anthropogenic activity, are decreasing the pH of the oceans. This thesis aimed to assess the biological response of foraminifera to ocean ...
  • The biology and ecology of benthic foraminifera inhabiting intertidal mudflats 

    Austin, Heather Anne (University of St Andrews, 2003) - Thesis
    Benthic foraminifera inhabiting the mudflats of the Eden Estuary, NE Scotland, exhibited a single annual peak in abundance at both high (270 individuals 10 cm⁻²) and low shore (210 individuals 10 cm⁻²) intertidal ...
  • The biology of South African Bryde's whales 

    Penry, Gwenith S. (University of St Andrews, 2010-06-23) - Thesis
    The biology of South African Bryde’s whales (Balaenoptera brydei/edeni), with a focus on the inshore form, was investigated through estimates of abundance and survival rate, seasonality of occurrence and variation in ...
  • Biomarkers of isoflavone intake : validity at high intakes 

    Mackinnon, L. Jay (University of St Andrews, 2007-06) - Thesis
    Isoflavones are biologically active plant chemicals (phytoestrogens) which are ordinarily present in human diets. There is considerable research interest in their potential to prevent or treat several chronic diseases. ...
  • Biomineralisation during operculum regeneration in the polychaete Spirobranchus lamarcki 

    Szabo, Reka; Calder, Angus; Ferrier, David Ellard Keith (2014-11) - Journal article
    Formation of calcified biominerals is widespread in marine animals and is often associated with important elements of their biology, such as support and protection. Serpulid polychaetes are relatively understudied examples ...
  • Biophysical aspects of photodynamic therapy 

    Valentine, Ronan (University of St Andrews, 2011-11-30) - Thesis
    Photodynamic therapy (PDT) is a multimodality cancer treatment available for the palliation or eradication of systemic and cutaneous malignancies. In this thesis, the application of PDT is for the treatment of non-melanoma ...

    Madsen, P T; Johnson, M; de Soto, N A; Zimmer, W M X; Tyack, P (2005-01-15) - Journal article
    Toothed whales (Cetacea, odontoceti) emit sound pulses to probe their surroundings by active echolocation. Noninvasive, acoustic Dtags were placed on deep-diving Blainville's beaked whales (Mesoplodon densirostris) to ...
  • Biparental incubation-scheduling : no experimental evidence for major energetic constraints 

    Bulla, M; Cresswell, Will; Rutten, A; Valcu, M; Kempenaers, B (2015) - Journal article
    Incubation is energetically demanding, but it is debated whether these demands constrain incubation-scheduling (i.e., the length, constancy, and timing of incubation bouts) in cases where both parents incubate. Using 2 ...
