  • 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 ...
  • Huey, Raymond B.; Berrigan, David (University of Chicago Press, 2001-08)
  • Lachmann, Michael; Szamado, Szabolcs; Bergstrom, Carl T. (National Academy of Sciences USA, 2001-11-06)
    The "costly signalling" hypothesis proposes that animal signals are kept honest by appropriate signal costs. We show that to the contrary, signal cost is unnecessary for honest signalling even when interests conflict. We ...
  • 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 ...
  • 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 ...
  • Ganusov, Vitaly V.; Bergstrom, Carl T.; Antia, Rustom (Society for the Study of Evolution, 2002-02)
    Why do parasites harm their hosts? The general understanding is that if the transmission rate and virulence of a parasite are linked, then the parasite must harm its host in order to maximize its transmission. The exact ...
  • 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 ...
  • Lipstitch, Marc; Bergstrom, Carl T.; Antia, Rustom (2003)
    Background: Doherty and Zinkernagel, who discovered that antigen presentation is restricted by the major histocompatibility complex (MHC, called HLA in humans), hypothesized that individuals heterozygous at particular MHC ...
  • Bergstrom, Carl T.; Lachmann, Michael (MIT Press, 2003)
    Mutualisms generate surpluses. While much of the theoretical literature to date focuses on mechanisms by which cooperation is stabilized so that these surpluses can continue to be produced and enjoyed, we address a second ...
  • 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)
  • 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 ...
  • 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.; 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 ...
  • Lipsitch, Marc; Bergstrom, Carl T.; Antia, Rustom (Biomed Central, 2003-01-24)
    Background: Doherty and Zinkernagel, who discovered that antigen presentation is restricted by the major histocompatibility complex (MHC, called HLA in humans), hypothesized that individuals heterozygous at particular MHC ...
  • 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 ...
  • Tanaka, Mark M.; Bergstrom, Carl T.; Levin, Bruce R. (Genetics Society of America, 2003-07)
    Recent studies have found high frequencies of bacteria with increased genomic rates of mutation in both clinical and laboratory populations. These observations may seem surprising in light of earlier experimental and ...
  • 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, ...
  • Lachmann, Michael; Bergstrom, Carl T. (The Royal Society of London, 2004)
    Combinatorial communication allows rapid and efficient transfer of detailed information, yet combinatorial communication is used by few, if any, non-human species. To complement recent studies illustrating the advantages ...
  • Bergstrom, Carl T.; Bergstrom, Theodore C. (Proceedings of the National Academy of Sciences USA, 2004)
    Scientific publishing is rapidly shifting from a paper-based system to one of predominantly electronic distribution, in which universities purchase site licenses for online access to journal contents. Will these changes ...
  • 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, ...
