  • Allometric scaling of maximum metabolic rate: the influence of temperature 
    White, C.R.   Terblanche, J.S.   Kabat, A.P.   Blackburn, T.M.   Chown, S.L.   Butler, P.J. (British Ecological Society, 2008)
    1. Maximum aerobic metabolic rate, measured in terms of rate of oxygen consumption during exercise (Vo2max ), is well known to scale to body mass (M) with an exponent greater than the value of 0•75 predicted by models based ...
  • The detection of spatial structure in populations and communities: An empirical case study 
    Warren, M.   McGeoch, M.A.   Chown, S.L. (Centre d'etudes nordique, Universite Laval, 2009)
    The presence of spatial autocorrelation in abundance and richness patterns has been recognised for some time. Evaluation of the tools to quantify patterning often uses simulated data that may be unrealistic or empirical ...
  • Evolutionary responses of discontinuous gas exchange in insects 
    White, C.R.   Blackburn, T.M.   Terblanche, J.S.   Marais, E.   Gibernau, M.   Chown, S.L. (The National Academy of Sciences of the USA, 2007)
    The discontinuous gas-exchange cycles (DGCs) observed in many quiescent insects have been a cause of debate for decades, but no consensus on their evolutionary origin or adaptive significance has been achieved. Nevertheless, ...
  • Factory flies are not equal to wild flies 
    Terblanche, J.S.   Chown, S.L. (AAAS, 2007)
  • A global indicator for biological invasion 
    McGeoch, MA   Chown, SL   Kalwij, JM (BLACKWELL PUBLISHING, 2006-12)
    "Trends in invasive alien species' is one of only two indicators of threat to biodiversity that form part of the Convention on Biological Diversity's (CBD) framework for monitoring progress toward its "2010 target" (ie., ...
  • Intraspecific body size frequency distributions of insects 
    Gouws, E.J.   Gaston, K.J.   Chown, S.L. (Public Library of Science (PLoS), 2011-03-30)
    Although interspecific body size frequency distributions are well documented for many taxa, including the insects, intraspecific body size frequency distributions (IaBSFDs) are more poorly known, and their variation among ...
  • Investigating onychophoran gas exchange and water balance as a means to inform current controversies in arthropod physiology 
    Clusella-Trullas, S.   Chown, S.L. (The Company of Biologists, 2008)
    Several controversies currently dominate the fields of arthropod metabolic rate, gas exchange and water balance, including the extent to which modulation of gas exchange reduces water loss, the origins of discontinuous gas ...
  • Landscape corridors: Possible dangers? 
    Procheş, Ş.   Wilson, J.R.U.   Veldtman, R.   Kalwij, J.M.   Richardson, D.M.   Chown, S.L. (AMER ASSOC ADVANCEMENT SCIENCE, 2005-11-04)
  • Macrophysiology for a changing world 
    Chown, S.L.   Gaston, K.J. (The Royal Society, 2008)
    The Millennium Ecosystem Assessment (MA) has identified climate change, habitat destruction, invasive species, overexploitation and pollution as the major drivers of biodiversity loss and sources of concern for human ...
  • Non-indigenous ungulates as a threat to biodiversity 
    Spear, D.   Chown, S.L. (The Zoological Society of London, 2009)
    Non-indigenous ungulate species pose a problem for conservation. They can be socially and economically valuable, but are also potentially harmful to biodiversity. Therefore, their introduction requires an explicit assessment ...
  • Physiological tolerances account for range limits and abundance structure in an invasive slug. 
    Lee, JE   Janion, C   Marais, E   Jansen van Vuuren, B   Chown, SL (The Royal Society, 2009)
    Despite the importance of understanding the mechanisms underlying range limits and abundance structure, few studies have sought to do so. Here we use a terrestrial slug species, Deroceras panormitanum, that has invaded a ...
  • South Africa: big science should stay on the agenda 
    Chown, S.L. (Macmillan Publishers Limited, 2010-03-04)
  • Variation in decomposition rates in the fynbos biome, South Africa: the role of plant species and plant stoichiometry 
    Bengtsson, Jan   Janion, Charlene   Chown, Steven L.   Leinaas, Hans Petter (Springer Science+Business Media B.V., 2011)
    Previous studies in the fynbos biome of the Western Cape, South Africa, have suggested that biological decomposition rates in the fynbos vegetation type, on poor soils, may be so low that fire is the main factor contributing ...
