  • 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 ...
  • 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 ...
  • Bergstrom, Carl T.; Bronstein, Judith L.; Bshary, Redouan; Connor, Richard C.; Daly, Martin; Frank, Steven A.; Gintis, Herbert; Keller, Laurant; Leimar, Olof; Noe, Ronald; Queller, David C. (MIT Press, 2003)
  • 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 ...
  • Bergstrom, Carl T.; McKittrick, Erin K.; Antia, Rustom (National Academy of Sciences USA, 2003-09-30)
    RNA silencing, found broadly throughout the eukaryotes, post-transcriptionally suppresses the expression of aberrant genes including those of many viruses and transposons. Similar to the specific immune system of vertebrates, ...
  • Lipsitch, Marc; Bergstrom, Carl T. (Kluwer, 2002)
    Mathematical models are valuable tools with which to predict and explain the epidemiology of nosocomial infection. As such, modeling will play a crucial role in the effort to control the growing threat posed in hospitals ...
  • Antia, Rustom; Bergstrom, Carl T.; Pilyugin, Sergei S.; Kaech, Susan M.; Ahmed, Rafi (Elsevier Science, 2003)
    Recent experimental results show that even brief stimulation with antigen can cause antigenspecic CD8 T-cells to undergo sustained proliferation followed by differentiation into memory cells. These results show that the ...
  • Haig, David; Bergstrom, Carl T. (Blackwell Publishing LTD, 1995)
    Most discussions of "sperm competition" have ignored the potential for competition among the different sperm genotypes present in the ejaculate of a single male. Rivalry within ejaculates may limit cooperation among the ...
  • Bergstrom, Carl T.; Lipsitch, Marc; Levin, Bruce R. (Genetics, 2000-08)
    Despite the near-ubiquity of plasmids in bacterial populations and the profound contribution of plasmid-borne genes and infectious gene transfer to the adaptation and evolution of bacteria, the mechanisms responsible for ...
  • Bergstrom, Carl T.; Antia, Rustom (Indian Academy of Sciences, 2005)
  • 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 ...
  • Genereux, Diane P.; Miner, Brooks E.; Bergstrom, Carl T.; Laird, Charles D. (National Academy of Sciences USA, 2005)
    Cytosine methylation is an epigenetic mechanism in eukaryotes that is often associated with stable transcriptional silencing, such as in X-chromosome inactivation and genomic imprinting. Aberrant methylation patterns occur ...
  • Bergstrom, Carl T.; Godfrey-Smith, Peter (Kluwer Academic Publishers, 1998)
    A wide range of ecological and evolutionary models predict variety in phenotype or behavior when a population is at equilibrium. This heterogeneity can be realized in different ways. For example, it can be realized through ...
  • Lipsitch, Marc; Bergstrom, Carl T. (American Journal of Epidemiology, 2004)
    Health officials faced a daunting task with the emergence of severe acute respiratory syndrome (SARS) last year: forecasting the trajectory of an emerging infectious disease and implementing effective control measures, ...
  • Bergstrom, Carl T.; Lachmann, Michael (National Academy of Sciences USA, 2003-01-21)
    Mutualisms provide benefits to those who participate in them. As a mutualism evolves, how will these benefits come to be allocated among the participants? We approach this question using evolutionary game theory and explore ...
  • Robson, Arthur J.; Bergstrom, Carl T.; Pritchard, Jonathan K. (Academic Press LTD Elsevier Scientific LTD, 1999)
    Patterns of reproductive uncertainty can have an important influence on population dynamics. There is a crucial distinction between what we describe here as aggregate uncertainty (in which reproductive output in each ...
  • Antia, Rustom; Regoes, Roland R.; Koella, Jacob C.; Bergstrom, Carl T. (Nature, 2003)
    It is unclear when, where and how novel pathogens such as human immunodeficiency virus (HIV), monkeypox and severe acute respiratory syndrome (SARS) will cross the barriers that separate their natural reservoirs from human ...
  • Bergstrom, Carl T.; Szamado, Szabolcs; Lachmann, Michael (The Royal Society of London, 2002-10-24)
    Much of the theoretical literature on costly signalling concentrates on the separating equilibria of continuous signalling games. At such equilibria, every signaller sends a distinct signal, and signal receivers are able ...
  • Bergstrom, Carl T.; Lachmann, Michael (National Academy of Sciences, 1998-04)
    The Sir Philip Sidney game has been used by numerous authors to show how signal cost can facilitate honest signaling among relatives. Here, we demonstrate that, in this game, honest cost-free signals are possible as well, ...
  • 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 ...
