    • On RNA interference as template immunity 

      Bergstrom, Carl T.; Antia, Rustom (Indian Academy of Sciences, 2005)
    • 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 ...
    • A population-epigenetic model to infer site-specific methylation rates from double-stranded DNA methylation patterns 

      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 ...
    • Pure versus mixed strategists: the evolution of behavioral heterogeneity in individuals and populations 

      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 ...
    • Real-Time Tracking of Control Measures for Emerging Infections 

      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, ...
    • The Red King Effect: When the slowest runner wins the coevolutionary race 

      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 ...
    • Risky business: Sexual and asexual reproduction in variable environments 

      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 ...
    • The role of evolution in the emergence of infectious diseases 

      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 ...
    • Separating equilibria in continuous signalling games 

      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 ...
    • Signalling Among Relatives. III. Talk is cheap. 

      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, ...
    • 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 ...
    • Survey of Shell-boring Microorganisms Across a Depth Gradient at Point Caution, on San Juan Island, WA 

      Johnson, Jeff (2011)
      Although they are integral to many marine ecosystems, relatively little is known about euendolithic (shell-boring) organisms outside the tropics. Here, I present a short survey of euendoliths inhabiting a site on the ...
    • Temperature, Demography, and Ectotherm Fitness 

      Huey, Raymond B.; Berrigan, David (University of Chicago Press, 2001-08)
    • Toward a theory of mutual mate choice: Lessons from two-sided matching 

      Bergstrom, Carl T.; Real, Leslie A. (Evolutionary Ecology LTD, 2000)
      Theoretical models of mate choice and sexual selection typically make one of two simplifying assumptions. Either mate-preferences are assumed to be uniform (e.g., all females have the same preferences with respect to males), ...
    • Transmission bottlenecks as determinants of virulence in rapidly evolving pathogens 

      Bergstrom, Carl T.; McElhany, Paul; Real, Leslie A. (National Academy of the Sciences, 1999-04)
      Transmission bottlenecks occur in pathogen populations when only a few individual pathogens are transmitted from one infected host to another in the initiation of a new infection. Transmission bottlenecks can dramatically ...
    • WikiDust: a TinkerCell Plugin to Annotate and Share Network Models 

      Johnson, Jeffrey; Sauro, Herbert M.; Chandran, Deepak; Galdzicki, Michal (2011)
      We present WikiDust, a software tool that (a) facilitates searches for DNA components, and (b) produces annotated webready images for improved sharing of designs. WikiDust is a plugin for TinkerCell, a CAD design tool ...
    • Within-host population dynamics and the evolution of microparasites in a heterogeneous host population 

      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 ...
