  • Effects of different soil structures on the decomposition of native and added organic carbon 

    Juarez, Sabrina; Nunan, Naoise; Duday, Anne-Claire; Pouteau, Valérie; Schmidt, Sonja; Hapca, Simona M.; Falconer, Ruth E.; Otten, Wilfred; Chenu, Claire (Elsevier, 2013)
    Soil microbial communities live in the soil pore network and therefore the access they have to organic substrate, oxygen and water depends on how this network is structured. In this experimental study, the relationship ...
  • An efficient Markov chain model for the simulation of heterogeneous soil structure 

    Wu, Keijan; Nunan, Naoise; Crawford, John W.; Young, Iain M.; Ritz, Karl (American Society of Agronomy, 2004)
    The characterization of the soil habitat is of fundamental importance to an understanding of processes associated with sustainable management such as environmental flows, bioavailability, and soil ecology. We describe a ...
  • Microbial distribution in soils: physics and scaling 

    Young, Iain M.; Crawford, John W.; Nunan, Naoise; Otten, Wilfred; Spiers, Andrew J. (Elsevier, 2008)
    In a handful of fertile soil there are billions of microorganisms and yet, even with a conservative estimate, the surface area covered by these organisms is considerably less than 1%. What does this tell us about the ...
  • Modeling the effect of soil meso- and macropores topology on the biodegradation of a soluble carbon substrate 

    Vogel, Laure E.; Makowski, David; Garnier, Patricia; Vieublé-Gonod, Laure; Coquet, Yves; Raynaud, Xavier; Nunan, Naoise; Chenu, Claire; Falconer, Ruth E.; Pot, Valérie (Elsevier, 2015-05-30)
    Soil structure and interactions between biotic and abiotic processes are increasingly recognized as important for explaining the large uncertainties in the outputs of macroscopic SOM decomposition models. We present a ...
  • Spatial distribution of bacterial communities and their relationships with the micro-architecture of soil 

    Nunan, Naoise; Wu, Kejian; Young, Iain M.; Crawford, John W.; Ritz, Karl (Blackwell Publishing Ltd., 2003-05-15)
    Biological soil thin-sections and a combination of image analysis and geostatistical tools were used to conduct a detailed investigation into the distribution of bacteria in soil and their relationship with pores. The ...
  • Three-dimensional microorganization of the soil–root–microbe system 

    Feeney, Debbie S.; Crawford, John W.; Daniell, Tim; Hallett, Paul D.; Nunan, Naoise; Ritz, Karl; Rivers, Mak; Young, Iain M. (Springer New York, 2006-07)
    Soils contain the greatest reservoir of biodiversity on Earth, and the functionality of the soil ecosystem sustains the rest of the terrestrial biosphere. This functionality results from complex interactions between ...
