Research Scientist - Landscape ecologist: climate change impacts and adaptation strategies for terrestrial biodiversity conservation

National Wildlife Research Centre (Ottawa, ON)


  • Understanding demographic drivers of species responses to climate change and land-use land-cover change
  • Climate change vulnerability assessments across (terrestrial) taxonomic groups
  • Spatial prioritisation of resources for conservation of species-at-risk/Conservation planning
  • Climate change adaptation strategies: translating predictive/population/species distribution model outcomes to inform decision-making
