  • Jumbam, K. R.   Terblanche, J. S.   Deere, J. A.   Somers, M. J.   Chown, Steven L. (Springer-Verlag, 2008-01)
    Despite the relative richness of spider species across the Southern Ocean islands remarkably little information is available on their biology. Here, the critical thermal limits of an indigenous (Myro kerguelenensis, Desidae) ...
  • Terblanche, John S.   Deere, Jacques A.   Clusella-Trullas, Susana   Janion, Charlene   Chown, Steven L. (Royal Society of Publishing, 2007)
    A full-factorial study of the effects of rates of temperature change and start temperatures was undertaken for both upper and lower critical thermal limits (CTLs) using the tsetse fly, Glossina pallidipes. Results show ...
  • White, Craig R.   Blackburn, Tim M.   Terblanche, John S.   Marais, Elrike   Gibernau, Marc   Chown, Steven L. (National Academy of Sciences, 2007-05)
    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, ...
  • Spear, Dian   Chown, Steven L. (Elsevier, 2009-02)
    Despite the apparent risks of the introduction of non-indigenous ungulates to biodiversity, relatively little is known globally about the pathways of introduction, propagule pressure and realized impacts of ungulate ...
  • Braschler, Brigitte   Chown, Steven L.   Gaston, Kevin J. (Public Library of Science (PLoS), 2012-03)
    Background: The Fynbos (FB) and Succulent Karoo biomes (SKB) have high regional plant diversity despite relatively low productivity. Local diversity in the region varies but is moderate. For insects, previous work suggests ...
  • Chown, Steven L.   Sinclair, Brent J.   Leinaas, Hans P.   Gaston, Kevin J. (PLoS One, 2004-11)
    Penguins have been receiving a lot of bad press lately. They are considered somehow counter, spare, strange. Unlike most plant and animal groups, they do not show a peak of species richness towards the equator and a ...
  • Gouws, E. Jeanne   Gaston, Kevin J.   Chown, Steven L. (Public Library of Science -- PLoS, 2011-03)
    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 ...
  • Clusella-Trullas, Susan   Chown, Steven L. (The Company of Biologists, 2008-08)
    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 ...
  • Chown, Steven L.   Gaston, Kevin J. (The Royal Society, 2008-07)
    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 ...
  • Spear, D.   Chown, Steven L. (Wiley-Blackwell, 2009-07)
    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 ...
  • Chown, Steven L.   Slabber, Sarette   McGeoch, Melodie A.   Janion, Charlene   Leinaas, Hans Petter (Royal Society Pulishing, 2007-10)
    Synergies between global change and biological invasion have been identified as a major potential threat to global biodiversity and human welfare. The global change-type drought characteristic of many temperate terrestrial ...
  • Janion, Charlene   Bedos, Anne   Bengtsson, Jan   Deharveng, Louis   Janse Van Vuuren, Bettine   Leinaas, Hans Petter   Liu, Amy   Malmstrom, Anna   Porco, David   Chown, Steven L. (Academy of Science of South Africa (ASSAf), 2011-11)
    Despite their significance in soil ecosystems and their use for investigations of soil ecosystem functioning and in bioindication elsewhere, springtails (Collembola) have not been well investigated in South Africa. Early ...
  • Lyons, Candic L.   Coetzee, Maureen   Chown, Steven L. (BioMed Central, 2013-04)
    Background: Understanding the biology of malaria vector mosquitoes is crucial to understanding many aspects of the disease, including control and future outcomes. The development rates and survival of two Afrotropical ...
  • Terblanche, John S.   Clusella-Trullas, Susana   Deere, Jacques A.   Chown, Steven L. (2008-01)
    For tsetse (Glossina spp.), the vectors of human and animal trypanosomiases, the physiological mechanisms linking variation in population dynamics with changing weather conditions have not been well established. Here, we ...
