Projecting cumulative effects of disturbance on boreal wildlife

We are collaborating on efforts to model the implications of ongoing natural and anthropogenic disturbance for forest dynamics and wildlife responses in the Western Boreal and Northern Ontario.

Addressing scientific & methodological challenges in connectivity conservation planning

Past work

A population demography modeling tool to explore harvest management scenarios for the Fortymile caribou herd

We parameterized a DG-Sim demographic model for the Fortymile caribou herd using Bayesian methods, and used to tool to assist managers with analysis of alternative harvest scenarios.

How to measure the impacts of antibiotic resistance and antibiotic development on empiric therapy: new composite indices

Two indices summarize the impact of antibiotic resistance on empiric therapy, accounting for drug availability and pathogen importance. They can be calculated from cumulative antibiogram data, and used to assess trends, interventions and potential threats.

Benefits and unintended consequences of antimicrobial de-escalation

Inadequate empiric therapy delays recovery and increases mortality, and resistance threatens the effectiveness of empiric drugs. De-escalation strategies aim to minimize the use of empiric drugs by switching to narrow spectrum alternatives when lab results indicate susceptibility. We investigated the consequences of this strategy using simulation models.

The effects of forest spatial structure on insect outbreaks: insights from a host-parasitoid model

We investigated the effects of landscape configuration and other factors on a spatial model of host-parasitoid (forest tent caterpillar) population dynamics. We also developed a new approximation technique to simplify model analysis and parameter estimation.

Pollen cone production in jack pine: spatial and temporal patterns subject to natural disturbance by the jack pine budworm

We used generalized linear mixed regression models to distinguish effects of defoliation on pollen cone production from spatially synchronous background variation in cone production.
