    • Eco-logy versus Eco-nomics 

      Cairns, John (Asian Journal of Experimental Sciences, 2009)
      The spelling of the words _eco-logy and _eco-nomics in the title is intended to emphasize that both words originated from the Greek word oikos, which means household, house, or family. Despite their common origin, never ...
    • Ecological costs and benefits of defenses in nectar 

      Adler, L. S.; Irwin, R. E. (Ecological Society of America, 2005-11)
      The nectar of many plant species contains defensive compounds that have been hypothesized to benefit plants through a variety of mechanisms. However, the relationship between nectar defenses and plant fitness has not been ...
    • Ecological Overshoot is Suicidal 

      Cairns, John (EcoRes Forum, 2009)
      December 19, 1987 marks the first day that humankind began living beyond its means and created a deficit for that year. Every year since 1987, humankind has had an ecological overshoot, or used more resources than the ...
    • Ecological Restoration in an Era of Ecological Disequilibrium 

      Cairns, John (Asian Journal of Experimental Sciences, 2006)
      The current rate of ecological destruction greatly exceeds the rate of ecological repair, a situation that obviously cannot continue indefinitely. In addition, the rate of biotic impoverishment makes finding suitable species ...

      Cairns, John (Science and Society, 2009)
      Partial ecological restoration of important attributes of Alder Creek, Gunnison County, CO, U.S.A., has been successful since the area has continued in its restored conditioni for over a decade. However, due to cattle ...
    • Ecology under lake ice 

      Hampton, Stephanie E.; Galloway, Aaron W.

A.; Timofeyev, Maxim A.; Toro, Manuel; Twiss, Michael R.; Vogt, Richard J.; Watson, Susan B.; Whiteford, Erika J.; Xenopoulos, Marguerite A. (2017-01)
      Winter conditions are rapidly changing in temperate ecosystems, particularly for those that experience periods of snow and ice cover. Relatively little is known of winter ecology in these systems, due to a historical ...
    • Ecosystem Function in Appalachian Headwater Streams during an Active Invasion by the Hemlock Woolly Adelgid 

      Northington, Robert M.; Webster, Jackson R.; Benfield, Ernest F.; Cheever, Beth M.; Niederlehner, Barbara R. (PLOS, 2013-04-22)
      Forested ecosystems in the southeastern United States are currently undergoing an invasion by the hemlock woolly adelgid (HWA). Previous studies in this area have shown changes to forest structure, decreases in canopy ...
    • Ecotoxicology in an Era of Rapid Environmental Change 

      Cairns, John (Virginia Tech, 2010)
      Ecotoxicology involves testing that uses attributes at higher levels of biological organization as endpoints. Ecotoxicologists have been accustomed to a relatively modest rate of environmental and ecosystem change. However, ...
    • Ecotoxicology Risk Assessment for a Changing World 

      Cairns, John (Science and Society, 2008)
      Exponential economic growth has resulted in grave damage to the biospheric life support system and the ecosystems that comprise it. The ubiquitous single-species toxicity tests providecrucial evidence on death, reproductive ...
    • Ectosymbionts alter spontaneous responses to the Earth’s magnetic field in a crustacean 

      Landler, L.; Skelton, J.; Painter, M.S.; Youmans, P.W.; Muheim, R.; Creed, R.P.; Brown, B.L.; Phillips, J.B. (Nature Publishing Group, 2019-02-28)
      Magnetic sensing is used to structure every-day, non-migratory behaviours in many animals. We show that crayfish exhibit robust spontaneous magnetic alignment responses. These magnetic behaviours are altered by interactions ...
    • Effect of Cetylpyridinium Chloride (CPC) on Colony Formation of Common Nontuberculous Mycobacteria
