    • By modelling the chronic wasting disease (CWD) transmission in deer populations with home range overlaps, we have been studying the effect of density, sex ratio and landscape on the spreading speed of the disease. Related Publications
  • Human impacts on Chronic Wasting Disease
    • In this project the aim is to develop an individual-based model with step-selection function movement rules to simulate the spread and

      transmission of chronic wasting disease.  This model will then be used to analyze the effects of supplemental feeding sites on transmission and spread over a range of site densities and arrangements. Related Publications

  • Sea lice infections in networks of salmon farms
    • Sea lice infections in networks of salmon farms: Sea lice are parasites which feed on salmon and can spread between salmon farms in dense salmon farming regions.The aim of this project is to develop a method for calculating which farms may be the largest sources for sea lice in the entire region, and to estimate the timing of sea lice spread between salmon farms.

  • Spatio-temporal dynamics of macroparasites
    • Macroparasites can spread spatially through host populations, affecting their fitness and their spatial distributions.  Here we use dynamical systems to model this process, with a particular emphasis on sea lice macroparasites on salmon populations. Related Publications
