Negligible effects of environmental fluctuations on the maintenance of coral biodiversity: A test of five storage effects
Evan C. Johnson, Sean R. Connolly
The storage effect is a general explanation for ecological coexistence, wherein different species specialize on different states of a fluctuating environment, e.g., hot vs. cold ye…
An assessment of Alberta's strategy for controlling mountain pine beetle outbreaks
Evan C. Johnson, Mark A. Lewis
The Canadian province of Alberta spent over 500 million dollars on controlling mountain pine beetle populations, but did it work? Using a statistical modeling framework coupled wit…
Biological barriers to forest pest invasions: A novel host tree slows mountain pine beetle range expansion
Evan C. Johnson, Antonia Musso, Catherine Cullingham +1
Following widespread outbreaks across western North America, mountain pine beetle recently expanded its range from British Columbia into Alberta. However, mountain pine beetle's ea…
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…
Explaining excitable population dynamics in bark beetles: From life history to large, episodic outbreaks
Evan C. Johnson, Antonia Musso, José F. Negron +1
Bark beetles are significant forest pests, with some species capable of causing widespread tree mortality. Among these, the mountain pine beetle (MPB) stands out for its exceptiona…
