Effects of birth pulses

Competition between native and invasive species represents a challenging management problem. We study the competition for resources between a native, desirable species and an efficient, invasive species. Competition interactions occur on a short timescale, while reproduction occurs in distinct pulses over a longer timescale.

A notable feature of this work is the use of a broadly applicable hybrid model, since many ecological processes occur over disparate timescales. Below are some important components of the research.

  • Embedding continuous dynamics in discrete model
  • Stability analysis and bifurcation for discrete map
  • Numerical investigation of instability

Future work on this project includes extending the model to include complex intraguild interactions (relevant to my interest in insect communities) and determining implications for long-term population outcomes.
