research is focused on carnivore movement ecology and I strive to
produce conservation-orientated information. I prefer to use
field-derived data, often from biotelemetry or camera traps, to
investigate species responses to landscape structure. With these
data I have explored mammalian responses to highways and habitats.
Recently, I have developed a novel model of corridor identification
via animal movement data and compared its performance to popular
cost-based approaches via camera trap detection data. I have
explored species morphological responses to changes in carnivore
community composition (i.e., the mesopredator release hypothesis) and
am currently investigating the responses of Mustela
individuals to seasonal changes (i.e., Dehnel’s phenomenon). I am
currently using accelerometer data to identify behaviours in free
ranging fishers (Pekania
and to quantify their behavioural responses to temporal changes in
automobile traffic volumes. I have collaborations with several
institutions, investigating animal movement and spatial processes via
movement data sets that I maintain on movebank.org. My goal is to
develop and validate a conservation orientated paradigm that builds
upon individual animal-based information to meet conservation
