  • 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 ...

  • 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 ...
  • Animating the Carbon Cycle

    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 ...
  • Archaeal Enzymes and Applications in Industrial Biocatalysts 

    Littlechild, JA (Hindawi Publishing Corporation, 2015-08-19)
    Archaeal enzymes are playing an important role in industrial biotechnology. Many representatives of organisms living in “extreme” conditions, the so-called Extremophiles, belong to the archaeal kingdom of life. This paper ...
  • Archiving primary data: solutions for long-term studies
