Biography

Rowenna’s PhD is on developing methods to quantitatively include Indigenous Knowledge (IK) into animal movement and habitat models. To address this she is focusing on ringed seals, spotted seals and bearded seals and their behaviour and habitat use in the Beaufort, Chukchi and Bering Seas. Rowenna will be conducting IK interviews in Arctic communities in Alaska to document the vast IK that exists in this region. She will then use a Bayesian statistical framework to equally include the IK and satellite movement data for these species to identify behaviour, such as foraging and resting, and identify suitable habitat. Rowenna hopes that through these methods IK can be included into modeling approaches in a new and meaningful way providing more fully informed models and understanding of animal movement and habitat use.
