    Oecologia 148:51-60. 2006
    ..Results of this study suggest over-compensatory density dependence as an underlying mechanism for recurrent traveling waves originating in high connectivity habitats aggregated around a single focus...
  2. ncbi Allee effects and pulsed invasion by the gypsy moth
    Derek M Johnson
    Department of Biology, University of Louisiana, PO Box 42451, Lafayette, Louisiana 70504, USA
    Nature 444:361-3. 2006
    ..Our results indicate that suppressing population peaks along range borders might greatly slow invasion...
  3. ncbi Climatic warming disrupts recurrent Alpine insect outbreaks
    Derek M Johnson
    Department of Biology, University of Louisiana, Lafayette, LA 70504, USA
    Proc Natl Acad Sci U S A 107:20576-81. 2010
    ..The threshold-like change in LBM outbreak pattern highlights how interacting species with differential response rates to climate change can result in dramatic ecological changes...
  4. ncbi Spatial synchrony propagates through a forest food web via consumer-resource interactions
    Kyle J Haynes
    Department of Biology, University of Louisiana, P O Box 42451, Lafayette, Louisiana 70504, USA
    Ecology 90:2974-83. 2009
    ..This work suggests that the transfer of synchrony among trophically linked species may be a major factor causing interspecific synchrony...

    Sophia R J Jang
    Department of Mathematics, University of Louisiana at Lafayette, LA, USA
    J Biol Dyn 3:209-23. 2009
    ..Existence and stability of equilibria are investigated and sufficient conditions for which populations can persist are derived. We then provide conclusions based on our analysis...
  6. ncbi Spatial analysis of harmonic oscillation of gypsy moth outbreak intensity
    Kyle J Haynes
    Department of Biology, University of Louisiana, P O Box 42451, Lafayette, LA 70504, USA
    Oecologia 159:249-56. 2009
    ..We suggest that this pattern emerges because high host-tree availability enhances the growth rates of gypsy moth populations...
