Weak signals, strong debates: Density dependence and population regulation through the lens of model uncertainty
Evan C. Johnson
Ecologists have long argued about the strength of density dependence and population regulation, respectively defined as the short-term and long-term rates of return to equilibrium.…
Negative density-dependent dispersal of the mountain pine beetle in Alberta
Evan C. Johnson, Mark Lewis
Understanding the mountain pine beetle's dispersal patterns is critical for evaluating its threat to Canada's boreal forests. It is generally believed that higher beetle densities…
Stratified dispersal explains mountain pine beetle's range expansion in Alberta
Evan C. Johnson, Micah Brush, Mark A. Lewis
The mountain pine beetle (MPB), a destructive pest native to Western North America, has recently extended its range into Alberta, Canada. Predicting the dispersal of MPB is challen…
Determinism vs. stochasticity in competitive flour beetle communities
Evan C. Johnson, Tad Dallas, Alan Hastings
As ecologists increasingly adopt stochastic models over deterministic ones, the question arises: when is this a positive development and when is this an unnecessary complication? W…
