  • Age-related declines in immune response in a wild mammal are unrelated to immune cell telomere length 

    Beirne, Christopher; Waring, L; McDonald, RA; Delahay, R; Young, AJ (Royal Society, 2016-02-17)
    Senescence has been hypothesised to arise in part from age-related declines in immune performance, but the patterns and drivers of within-individual age-related changes in immunity remain virtually unexplored in natural ...

  • Akt regulates centrosome migration and spindle orientation in the early Drosophila melanogaster embryo. 

    Buttrick, GJ; Beaumont, LM; Leitch, J; Yau, C; Hughes, JR; Wakefield, JG (Rockefeller University Press, 2008-02-11)
    Correct positioning and morphology of the mitotic spindle is achieved through regulating the interaction between microtubules (MTs) and cortical actin. Here we find that, in the Drosophila melanogaster early embryo, reduced ...
  • An alternative transdiagnostic mechanistic approach to affective disorders illustrated with research from clinical psychology 

    Watkins, E.R (Sage, 2015-04-10)
    Current psychiatric classification adopts a disorder-focused diagnostic approach, as exemplified within ICD-11 and DSM-V. Although this approach has improved reliability of categorisation, its validity and utility has been ...
  • Amplification of a cytochrome P450 gene is associated with resistance to neonicotinoid insecticides in the aphid Myzus persicae. 

    Puinean, AM; Foster, SP; Oliphant, L; Denholm, I; Field, LM; Millar, NS; Williamson, MS; Bass, C (Public Library of Science, 2010-06-24)
    The aphid Myzus persicae is a globally significant crop pest that has evolved high levels of resistance to almost all classes of insecticide. To date, the neonicotinoids, an economically important class of insecticides ...
  • Analysis of climate paths reveals potential limitations on species range shifts 

    Early, Regan; Sax, Dov F. (Wiley, 2011)
    Forecasts of species endangerment under climate change usually ignore the processes by which species ranges shift. By analysing the 'climate paths' that range shifts might follow, and two key range-shift processes--dispersal ...
  • Analysis of known bacterial protein vaccine antigens reveals biased physical properties and amino acid composition 

    Mayers, Carl; Duffield, Melanie; Rowe, Sonya; Miller, Julie; Lingard, Bryan; Hayward, Sarah; Titball, Richard W. (Hindawi Publishing Corporation, 2003)
    Many vaccines have been developed from live attenuated forms of bacterial pathogens or from killed bacterial cells. However, an increased awareness of the potential for transient side-effects following vaccination has ...
  • Analysis of whole genome sequencing for the Escherichia coli O157:H7 typing phages 

    Cowley, Lauren A.; Beckett, Stephen J.; Chase-Topping, Margo; Perry, Neil; Dallman, Tim J.; Gally, David L.; Jenkins, Claire (BioMed Central, 2015-04-08)
    Background: Shiga toxin producing Escherichia coli O157 can cause severe bloody diarrhea and haemolytic uraemic syndrome. Phage typing of E. coli O157 facilitates public health surveillance and outbreak investigations, ...
  • The ancestral symbiont sensor kinase CSK links photosynthesis with gene expression in chloroplasts. 

    Puthiyaveetil, S; Kavanagh, TA; Cain, P; Sullivan, JA; Newell, CA; Gray, JC; Robinson, C; van der Giezen, M; Rogers, MB; Allen, John F. (2008-07-22)
    We describe a novel, typically prokaryotic, sensor kinase in chloroplasts of green plants. The gene for this chloroplast sensor kinase (CSK) is found in cyanobacteria, prokaryotes from which chloroplasts evolved. The CSK ...
  • Ancient diversification of eukaryotic MCM DNA replication proteins. 

    Aves, Stephen; Richards, Thomas A; Liu, Yuan (BioMed Central, 2009)
    Yeast and animal cells require six mini-chromosome maintenance proteins (Mcm2-7) for pre-replication complex formation, DNA replication initiation and DNA synthesis. These six individual MCM proteins form distinct heterogeneous ...
  • Ancient pre-glacial erosion surfaces preserved beneath the West Antarctic Ice Sheet 

    Rose, K.C.; Ross, N; Jordan, T.A.; Bingham, R.G.; Corr, H.F.J.; Le Brocq, A.M.; Ferraccioli, F; Rippin, D.M.; Siegert, M.J. (European Geosciences Union (EGU) / Copernicus Publications, 2015-02-16)
    present ice-penetrating radar evidence for ancient (pre-glacial) and extensive erosion surfaces preserved beneath the upstream Institute and Möller ice streams, West Antarctica. Radar data reveal a smooth, laterally ...
  • Animal geographies II: methods 

    Buller, HJ (Sage, 2014)
    Animal geographies challenge not only the place and placing of the human and the animal but, critically, the methods we use to engage with both in relation. This second review considers the various methodological implications ...
  • Animal Geographies III: Ethics 

    Buller, HJ (SAGE Publications, 2015-04-19)
    There is no animal geography without ethics. The very coupling of the words gives rise to an ethical endeavor; an acceptance that animals have a geography, a making visible of animals within our human geography and ...
  • Animal minds: from computation to evolution. 

    Thornton, A; Clayton, Nicola S.; Grodzinski, U (Royal Society, 2012-10-05)
    In the great Darwinian struggle for existence, all animals must tackle the problems posed by variable environments, be it finding and processing food, recognizing and attracting potential mates, avoiding predators, ...
  • Animal personality: What are behavioural ecologists measuring? 

    Carter, Alecia J.; Feeney, WE; Marshall, Harry H.; Cowlishaw, Guy; Heinsohn, R (Wiley, 2013-05)
    The discovery that an individual may be constrained, and even behave sub-optimally, because of its personality type has fundamental implications for understanding individual- to group-level processes. Despite recent interest ...
  • Animating the Carbon Cycle
