      An orb web's prey capture thread features tiny glue droplets, each formed of an adhesive glycoprotein core surrounded by an aqueous layer. Small molecules in the aqueous layer confer droplet hygroscopicity and maintain ...
    • Eliminating Ecological Overshoot 

      Cairns, John (Asian Journal of Experimental Sciences, 2008)
      Ecological overshoot is the result of using Earth's resources faster than they can be regenerated (Wackernagel et al., 2002). In 2007, humankind is using about 30% more resources in one year than nature can regenerate in ...
    • The End of Abundance: Will it Bring Resource Wars or Sharing 

      Cairns, John (EcoRes Forum, 2009)
      Presently, limitations on recourses are increasing and the human population is running out of resources at a dangerous rate. We are trying to solve massive problems, like biodiversity loss, climate change and poverty ...
    • The End of Contagious Optimism and Denial 

      Cairns, John (Virginia Tech, 2008)
      The term tipping point was coined in the field of epidemiology to explain the concept that small changes will have little or no effect on a system until a specific critical mass is reached. Once this pint is reached, any ...
    • The End of the Car Culture and the Reemergence of Public Transportation 

      Cairns, John (Asian Journal of Experimental Sciences, 2009)
      The United States, which has been the poster child for car culture, has been warned of the unparalleled prospect of trillion-dollar deficits for years to come. Most state governments face severe reduction in tax monies, ...
    • The End of the Cornucopian Delusion 

      Cairns, John (Virignia Tech, 2007)
      Many believe that they can achieve the cornucopian dream by getting to a certain place, such as the United States, where others may be appearing to live the dream, even though all evidence shows that the Industrial age and ...
    • Endogenous and exogenous control of ecosystem function: N cycling in headwater streams 

      Valett, H. M.; Thomas, S. A.; Mulholland, P. J.; Webster, J. R.; Dahm, C. N.; Fellows, C. S.; Crenshaw, C. L.; Peterson, C. G. (Ecological Society of America, 2008-12)
      Allochthonous inputs act as resource subsidies to many ecosystems, where they exert strong influences on metabolism and material cycling. At the same time, metabolic theory proposes endogenous thermal control independent ...
    • Energy costs of subduing and swallowing prey for a lizard 

      Pough, F. Harvey; Andrews, Robin M. (Ecological Society of America, 1985)
      We measured the oxygen consumption (aerobic energy cost) and lactic acid production (anaerobic energy cost) of scincid lizards, Chalcides ocellatus, eating domestic crickets. Aerobic metabolism accounted for 90% or more ...
