    Carter, Alecia J.; Feeney, WE; Marshall, Harry H.; Cowlishaw, Guy; Heinsohn, R (Wiley, 2013-05)

    Simpson, SD; Purser, J; Radford, AN (Wiley, 2014-08-06)

    Simpson, SD; Radford, AN; Nedelec, SL; Ferrari, MCO; Chivers, DP; McCormick, MI; Meekan, MG (Nature Publishing Group, 2016-02-05)
    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 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.
