MoosePOPd: Population Dynamics in the Presence of Lethal Parasites

We draw upon equations in population matrix models to assess whether disease drives population trends in New York moose.
Annual trajectories and population abundances for bald eagles

Northeast bald eagle population dynamics through the lens of veterinary science

We draw upon equations in matrix models to assess whether lead mortalities have influenced population trends of bald eagles in the Northeast United States.

IsoPOPd: Theoretical Population Modeling for Understanding Growth Rates

Demographers use eigenvalues to assess population viability of wildlife. But what is an eigenvalue? And how is it calculated? Do our management actions cause the eigenvalue to change? Our interactive IsoPOPd app demonstrates how vital rates collapse into the growth rate via a single balance equation. Use the interactive app to increase your understanding of how management activities that modify one vital rate not only change the growth rate, but how that same management activity translates to change that ripples through the system.

StallPOPd Software: Population Reduction of a Subsidized Predator

When population growth of a subsidized predator skyrockets, what can be done to mitigate the impacts to its vulnerable prey? Population matrix models can help identify strategies to combat the population growth of predators.

StaPOPd: Applied Stable Population Theory for Wildlife Species Reintroduction

When wildlife populations become too small to remain stable or when they have disappeared entirely, reintroduction can be a key to a successful recovery. But how many animals should be introduced? Stable population theory can help determine that.
