  • Accounting for variability in soil microbial communities of temperate upland grassland ecosystems 
    Griffith, Gwyn S.; Campbell, Colin D.; Mawdsley, J. L.; Grayston, Susan J.; Bardgett, Richard D. (2001)
    This study aimed to determine the factors which regulate soil microbial community organisation and function in temperate upland grassland ecosystems. Soil microbial biomass (Cmic), activity (respiration and potential carbon ...
  • Arctic microorganisms respond more to elevated UV-B radiation than CO2 
    Lee, John A.; Campbell, Colin D.; Callaghan, Terry V.; Gwynn-Jones, Dylan; Johnson, David (2002-03-07)
    Surface ultraviolet-B radiation and atmospheric CO2 concentrations have increased as a result of ozone depletion and burning of fossil fuels1, 2. The effects are likely to be most apparent in polar regions3 where ozone ...
  • Arctic microorganisms respond more to elevated UV-B radiation than CO2 
    Johnson, David; Campbell, Colin D.; Lee, John A.; Callaghan, Terry V.; Gwynn-Jones, Dylan (Nature Publishing Group, 2002)
    Surface ultraviolet-B radiation and atmospheric CO2 concentrations have increased as a result of ozone depletion and burning of fossil fuels1, 2. The effects are likely to be most apparent in polar regions3 where ozone ...
  • Brief Communications - UV-B radiation and soil microbial communities - Reply. 
    Callaghan, Terry V.; Johnson, David; Campbell, Colin D.; Lee, John A.; Gwynn-Jones, Dylan (2003)
    Stark and Hart question our finding that increased UV-B irradiation affects the biomass C:N ratio of Arctic soil microbial communities. Our data for microbial carbon biomass (Cmic; 1.0–3.1 mg per g soil) and nitrogen (Nmic; ...
