    Greg Dwyer
    Department of Ecology and Evolution, 1101 E 57th Street, University of Chicago, Chicago, Illinois 60637 1573, USA
    Nature 430:341-5. 2004
    ..Outbreaks in this model occur at long but irregular intervals, matching the data. Our results suggest that explanations of insect outbreaks must go beyond classical models to consider interactions among multiple species...

    Greg Dwyer
    Department of Ecology and Evolution, University of Chicago, Chicago, Illinois 60637 1573, USA
    Am Nat 165:16-31. 2005
    ..Our work provides a clear example of how two-species models are sometimes sufficient to describe what appear to be tritrophic interactions...
  3. ncbi request reprint Resource-dependent dispersal and the speed of biological invasions
    Greg Dwyer
    Department of Ecology and Evolution, University of Chicago, Chicago, Illinois 60637, USA
    Am Nat 167:165-76. 2006
    ..More practically, our work suggests that reducing invader densities behind the front may be a useful method of slowing an invader's rate of spread...
  4. doi request reprint Using mechanistic models to understand synchrony in forest insect populations: the North American gypsy moth as a case study
    Karen C Abbott
    Department of Ecology and Evolution, University of Chicago, Chicago, Illinois 60637, USA
    Am Nat 172:613-24. 2008
    ..By relating alterations in model structure to changes in synchrony levels, we show that the synchrony is due to a combination of spatial covariance in environmental stochasticity and the origins of chaos in our multispecies model...
  5. ncbi request reprint Food limitation and insect outbreaks: complex dynamics in plant-herbivore models
    Karen C Abbott
    Department of Ecology and Evolution, University of Chicago, 1101 E 57th Street, Chicago, IL 60637, USA
    J Anim Ecol 76:1004-14. 2007
    ..Our results demonstrate that insect outbreaks can be explained by a combination of food limitation in the herbivore and defoliation and intraspecific competition in the host plant...
  6. ncbi request reprint Combining stochastic models with experiments to understand the dynamics of monarch butterfly colonization
    Kevin L S Drury
    Department of Ecology and Evolution, University of Chicago, Chicago, Illinois 60637, USA
    Am Nat 166:731-50. 2005
    ..This result is consistent with our experiments and suggests that experiments can enhance the usefulness of stochastic models in ecology...

  1. Natural Selection, Host-Pathogen Interactions, and Insect Outbreaks
    Gregory Dwyer; Fiscal Year: 2010
    ..If models that include host or pathogen evolution do a better job of explaining data on outbreaks, the Pi's will conclude that host and pathogen evolution play a role in insect outbreaks in nature. ..
