  • Ancient diversification of eukaryotic MCM DNA replication proteins. 

    Aves, Stephen; Richards, Thomas A; Liu, Yuan (BioMed Central, 2009)

  • 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 ...

    Noise-generating human activities affect hearing, communication and movement in terrestrial and aquatic animals, but direct evidence for impacts on survival is rare. We examined effects of motorboat noise on post-settlement ...
  • Anthropogenic noise playback impairs embryonic development and increases mortality in a marine invertebrate. 

    Nedelec, SL; Radford, AN; Simpson, SD; Nedelec, B; Lecchini, D; Mills, SC (Nature Publishing Group, 2014-07-31)
    Human activities can create noise pollution and there is increasing international concern about how this may impact wildlife. There is evidence that anthropogenic noise may have detrimental effects on behaviour and physiology ...
  • Antibiotic Cycling and Antibiotic Mixing: which one best mitigates antibiotic resistance? 

    Beardmore, RE; Pena-Miller, R; Gori, F; Iredell, J (Oxford University Press, 2017-01-17)
    Can we exploit our burgeoning understanding of molecular evolution to slow the progress of drug resistance? One role of an infection clinician is exactly that: to foresee trajectories to resistance during antibiotic treatment ...
  • 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 ...
  • AP39, a novel mitochondria-targeted hydrogen sulfide donor, stimulates cellular bioenergetics, exerts cytoprotective effects and protects against the loss of mitochondrial DNA integrity in oxidatively stressed endothelial cells in vitro. 

    Szczesny, B; Módis, K; Yanagi, K; Coletta, C; Le Trionnaire, S; Perry, A; Wood, ME; Whiteman, M; Szabo, C (Elsevier, 2014-04-19)
    The purpose of the current study was to investigate the effect of the recently synthesized mitochondrially-targeted H2S donor, AP39 [(10-oxo-10-(4-(3-thioxo-3H-1,2-dithiol-5yl)phenoxy)decyl) triphenylphosphonium bromide], ...
  • Application of nitrogen and carbon stable isotopes (δ(15)N and δ(13)C) to quantify food chain length and trophic structure 

    Perkins, MJ; McDonald, RA; van Veen, FJ; Kelly, SD; Rees, G; Bearhop, S (Public Library of Science, 2014)
    Increasingly, stable isotope ratios of nitrogen (δ(15)N) and carbon (δ(13)C) are used to quantify trophic structure, though relatively few studies have tested accuracy of isotopic structural measures. For laboratory-raised ...
