  • 2,4-Dichlorophenoxyacetic acid promotes S-nitrosylation and oxidation of actin affecting cytoskeleton and peroxisomal dynamics 

    Rodríguez-Serrano, M.; Pazmino, D.M.; Sparkes, Imogen; Rochetti, A.; Hawes, Chris; Romero-Puertas, M.C.; Sandalio, L.M. (Oxford University Press (OUP) for Society for Experimental Biology (SEB), 2014-06-09)
    2,4-Dichlorophenoxyacetic acid (2,4-D) is a synthetic auxin used as a herbicide to control weeds in agriculture. A high concentration of 2,4-D promotes leaf epinasty and cell death. In this work, the molecular mechanisms ...
  • Active Management of Protected Areas Enhances Metapopulation Expansion Under Climate Change 

    Lawson, CR; Bennie, Jonathan; Thomas, CD; Hodgson, Jenny A.; Wilson, RJ (Wiley-Blackwell, 2014-06-11)
    There is a need to adapt biodiversity conservation to climate change, but few empirical studies are available to guide decision-making. Existing networks of protected areas (PAs) have been preferentially colonized during ...
  • The aerodynamics and efficiency of wind pollination in grasses 

    Cresswell, James; Krick, J; Patrick, MA; Lahoubi, M (Wiley-Blackwell, 2010-08)
    Summary 1. Under natural selection for sexual success, the reproductive organs of plants should evolve to become highly effective pollen receptors. Among wind-pollinated plants, larger reproductive structures appear ...
  • Age-related declines and disease-associated variation in immune cell telomere length in a wild mammal 

    Beirne, Christopher; Delahay, R; Hares, M; Young, AJ (Public Library of Science, 2014-09-30)
    Immunosenescence, the deterioration of immune system capability with age, may play a key role in mediating age-related declines in whole-organism performance, but the mechanisms that underpin immunosenescence are poorly ...
  • 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, The, 2016)
    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 ...
  • 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 ...
  • 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 

    Schmitz, OJ; Raymond, PA; Estes, JA; Kurz, WA; Holtgrieve, GW; Ritchie, ME; Schindler, DE; Spivak, AC; Wilson, RW; Bradford, MA; Christensen, V; Deegan, L; Smetacek, V; Vanni, MJ; Wilmers, CC (Springer Verlag, 2013-09-19)
    Understanding the biogeochemical processes regulating carbon cycling is central to mitigating atmospheric CO2 emissions. The role of living organisms has been accounted for, but the focus has traditionally been on contributions ...
  • Annual Variation in Sterol Levels in Leaves of Taraxacum officinale Weber 1 

    Westerman, Lynne; Roddick, James G. (1981-10)
    Sterol levels in dandelion (Taraxacum officinale Weber) leaves were monitored over a period of 19 months. Sitosterol was the most abundant free sterol, followed by stigmasterol, then campesterol. Cholesterol could not be ...
  • Anthropogenic noise compromises antipredator behaviour in European eels. 

    Simpson, SD; Purser, J; Radford, AN (Wiley, 2014-08-06)
    Increases in noise-generating human activities since the Industrial Revolution have changed the acoustic landscape of many terrestrial and aquatic ecosystems. Anthropogenic noise is now recognized as a major pollutant of ...
  • Antibiotic cycling versus mixing: the difficulty of using mathematical models to definitively quantify their relative merits. 

    Pena-Miller, R; Beardmore, Robert (American Institute of Mathematical Sciences, 2010-10)
    We ask the question Which antibiotic deployment protocols select best against drug-resistant microbes: mixing or periodic cycling? and demonstrate that the statistical distribution of the performances of both sets of ...
  • Antioxidant supplementation during early development reduces parasite load but does not affect sexual ornament expression in adult ring-necked pheasants Phasianus colchicus 

    Orledge, JM; Blount, Jonathan D.; Hoodless, AN; Royle, NJ (Wiley/ British Ecological Society, 2012-03-12)
    1. The ‘parasite-mediated sexual selection’ (PMSS) hypothesis predicts that exaggerated male ornamentation could provide a signal to females of a males ability to resist parasites. Empirical tests of the PMSS have been ...
