  • 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 ...
  • 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 ...
  • South Africa: big science should stay on the agenda 
    Chown, S.L. (Macmillan Publishers Limited, 2010-03-04)
  • Indirect effects of invasive species removal devastate World Heritage island 
    Bergstrom, Dana M.   Lucieer, Arko   Kiefer, Kate   Wasley, Jane   Belbin, Lee   Pedersen, Tore K.   Chown, Steven L. (British Ecological Society, 2009)
    1. Owing to the detrimental impacts of invasive alien species, their control is often a priority for conservation management. Whereas the potential for unforeseen consequences of management is recognized, their associated ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • Factory flies are not equal to wild flies 
    Terblanche, J.S.   Chown, S.L. (AAAS, 2007)
  • Cuticular lipid mass and desiccation rates in Glossina pallidipes : interpopulation variation 
    Jurenka, Russell   Terblanche, John S.   Klok, C. Jaco   Chown, Steven L.   Krafsur, Elliot S. (The Royal Entomological Society, 2007)
    Tsetse flies, Glossina pallidipes (Diptera: Glossinidae) are said to have strong dispersal tendencies. Gene flow among these populations is estimated to be the theoretical equivalent of no more than one or two reproducing ...
  • 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, ...
  • Mytilus on the move : transport of an invasive bivalve to the Antarctic 
    Lee, J. E.   Chown, Steven L. (Inter-Research, 2007)
    Increasing numbers of scientific and tourist vessels are entering the Antarctic region and have the potential to bring with them a range of organisms that are not currently found in the region. Little is known about the ...
  • Conserving pattern and process in the Southern Ocean : designing a Marine Protected Area for the Prince Edward Islands 
    Lombard, A. T.   Reyers, B.   Schonegevel, L. Y.   Cooper, J.   Smith-Adao, L. B.   Nel, D. C.   Froneman, P. W.   Ansorge, I. J.   Bester, M. N.   Tosh, C. A.   Strauss, T.   Akkers, T.   Gon, O.   Leslie, R. W.   Chown, Steven L. (Antarctic Science Ltd, 2007)
    South Africa is currently proclaiming a Marine Protected Area (MPA) in the Exclusive Economic Zone (EEZ) of its sub-Antarctic Prince Edward Islands. The objectives of the MPA are to: 1) contribute to a national and global ...
  • Rapid cold-hardening in a Karoo beetle, Afrinus sp. 
    Sinclair, Brent J.   Chown, Steven L. (The Royal Entomological Society, 2006)
    In the insect rapid cold-hardening response, survival at subzero temperatures is greatly improved by a brief pre-exposure at a milder temperature. It is predicted that insects with minimal cold tolerance capabilities living ...
