• Parasite-mediated disruptive selection in a natural Daphnia population 

      Duffy, Meghan A.; Brassil, Chad E.; Hall, Spencer R.; Tessier, Alan J.; Cáceres, Carla E.; Conner, Jeffrey K. (Georgia Institute of TechnologyBioMed Central, 2008-03-07)
      Background. A mismatch has emerged between models and data of host-parasite evolution. Theory readily predicts that parasites can promote host diversity through mechanisms such as disruptive selection. Yet, despite these ...
    • Rapid evolution, seasonality, and the termination of parasite epidemics 

      Duffy, Meghan A.; Hall, Spencer R.; Cáceres, Carla E.; Ives, Anthony R. (Georgia Institute of TechnologyEcological Society of America, 2009-06)
      Why do epidemics end? This simple question has puzzled ecologists and epidemiologists for decades. Early explanations focused on drops in host density arising from highly virulent parasites and, later, on the effects of ...
    • Temporal, spatial, and between-host comparisons of patterns of parasitism in lake zooplankton 

      Duffy, Meghan A.; Cáceres, Carla E.; Hall, Spencer R.; Tessier, Alan J.; Ives, Anthony R. (Georgia Institute of TechnologyEcological Society of America, 2010-11)
      In nature, multiple parasite species infect multiple host species and are influenced by processes operating across different spatial and temporal scales. Data sets incorporating these complexities offer exciting opportunities ...
    • Warmer does not have to mean sicker: temperature and predators can jointly drive timing of epidemics 

      Hall, Spencer R.; Tessier, Alan J.; Duffy, Meghan A.; Huebner, Mariann; Cáceres, Carla E. (Georgia Institute of TechnologyEcological Society of America, 2006-07)
      Ecologists and epidemiologists worry that global warming will increase disease prevalence. These fears arise because several direct and indirect mechanisms link warming to disease, and because parasite outbreaks are ...
