    • Behavioral Drive versus Behavioral Inertia in Evolution: A Null Model Approach 

      Huey, Raymond B.; Hertz, Paul E.; Sinervo, B. (University of Chicago Press, 2003-03)
      Some biologists embrace the classical view that changes in behavior inevitably initiate or drive evolutionary changes in other traits, yet others note that behavior sometimes inhibits evolutionary changes. Here we develop ...
    • Behavioral thermoregulation in lizards: importance of associated costs 

      Huey, Raymond B. (American Association for the Advancement of Science, 1974-05-31)
      The Puerto Rican lizard Anolis cristatellus behaviorally regulates body temperature in an open habitat but passively tolerates lower and more variable temperatures in an adjacent forest where basking sites are few and ...
    • Ecological consequences of foraging mode 

      Huey, Raymond B.; Pianka, Eric R. (Ecological Society of America, 1981-08)
      Desert lizards are typically either widely foraging or sit-and-wait predators, and these foraging modes are correlated with major differences in ecology. Foraging mode is related to the type of prey eaten by lizards. Widely ...
    • Evaluating temperature regulation by field-active ectotherms: the fallacy of the inappropriate question 

      Hertz, Paul E.; Huey, Raymond B.; Stevenson, R. D. (University of Chicago, 1993-11)
      We describe a research protocol for evaluating temperature regulation from data on small field-active ectothermic animals, especially lizards. The protocol requires data on body temperatures (Tb) of field-active ectotherms, ...
    • Hot rocks and not-so-hot rocks: retreat-site selection by garter snakes and its thermal consequences 

      Huey, Raymond B.; Peterson, Charles R.; Arnold, Stevan J.; Porter, Warren P. (Ecological Society of America, 1989-08)
      Studies of behavioral thermoregulation of ectotherms have typically focused only on active animals. However, most temperate-zone ectotherms actually spend more time sequestered in retreats (e.g., under rocks) than active ...
    • How often do lizards "run on empty"? 

      Huey, Raymond B.; Pianka, Eric R.; Vitt, Laurie J. (Ecological Society of America, 2001-01)
      Energy balance is relevant to diverse issues in ecology, physiology, and evolution. To determine whether lizards are generally in positive energy balance, we synthesized a massive data set on the proportion of individual ...
    • Latitudinal pattern of between-altitude faunal similarity: mountains might be "higher" in the tropics 

      Huey, Raymond B. (The University of Chicago, 1978-01)
      Moving up or down a mountain from a given site, one encounters faunas that differ by varying degrees. The elevational separation between sites obviously influences the magnitude of that difference (faunal similarity is ...
    • Plants versus animals: do they deal with stress in different ways? 

      Huey, Raymond B.; Carlson, Margen; Crozier, Lisa; Frazier, Melanie; Hamilton, Hayden; Harley, Christopher; Hoang, Anhthu; Kingsolver, Joel G. (Society of Integrative and Comparative Biology, 2002)
      Both plants and animals respond to stress by using adaptations that help them evade, tolerate, or recover from stress. In a synthetic paper A. D. Bradshaw (1972) noted that basic biological differences between plants and ...
    • Supplemental oxygen and mountaineer death rates on Everest and K2 

      Huey, Raymond B.; Eguskitza, Xavier (American Medical Association, 2000-07-12)
      The use of supplemental oxygen by Himalayan mountaineers has been debated for more than 8 decades. Although sometimes viewed as unsporting, supplemental-oxygen use may improve survival rates by increasing performance and ...
    • Temperature, Demography, and Ectotherm Fitness 

      Huey, Raymond B.; Berrigan, David (University of Chicago Press, 2001-08)
