Journal of Anatomy, 2018 Narwhals (Monodon monoceros) and belugas (Delphinapterus leucas) are the only extant members of the Monodontidae, and are charismatic Arctic‐endemic cetaceans that are at risk from global change. Investigating the anatomy and sensory apparatuses of these

Inclusivity of Indigenous Knowledge Systems in Fisheries Management
Fish and Fisheries, Volume 26, Issue 4, Page 669-687, July 2025.ABSTRACT Indigenous Peoples have developed knowledge systems that foster respectful and reciprocal relations between humans and other‐than‐human beings, supporting resilient ecosystems and societies. Despite the impacts of colonisation, Indigenous Knowledge Systems (IKS) endure in many parts of the world, and there is growing recognition that IKS can ...

Improved order selection method for hidden Markov models: A case study with movement data
Methods in Ecology and Evolution, Volume 16, Issue 6, Page 1215-1227, June 2025.Abstract Hidden Markov models (HMMs) are a versatile statistical framework commonly used in ecology to characterize behavioural patterns from animal movement data. In HMMs, the observed data depend on a finite number of underlying hidden states, generally interpreted as the animal's unobserved behaviour. The number of states is a crucial hyperparameter,

Environmental DNA, Volume 7, Issue 3, May–June 2025.Environmental DNA (eDNA) techniques have been successfully used to detect cetacean species, including harbor porpoises, humpback whales, and killer whales, through direct “flukeprint” sampling. This study assessed the persistence of eDNA shed in flukeprints by collecting seawater samples at timed intervals (up to 10 min) following dives of these ...

Preliminary evidence for signature vocalizations among free-ranging narwhals (Monodon monoceros) [PDF]
The Journal of the Acoustical Society of America, 2006 Animal signature vocalizations that are distinctive at the individual or group level can facilitate recognition between conspecifics and re-establish contact with an animal that has become separated from its associates. In this study, the vocal behavior of two free-ranging adult male narwhals (Monodon monoceros) in Admiralty Inlet, Baffin Island was ...

Proximity analysis between icebreakers and narwhals in Tasiujaq, Nunavut, Canada
The Journal of Wildlife Management, Volume 88, Issue 8, November 2024.This study looked at the proximity between icebreakers and narwhals in Tasiujaq, Nunavut, Canada. All icebreakers in the area had at least one encounter with a narwhal, approaching as close as less than 1 km. Cumulative time in proximity to vessels can have negative impacts on narwhals in their summering habitat.

Modeling population dynamics of beluga whales in the Eastern High Arctic – Baffin Bay population
The Journal of Wildlife Management, Volume 88, Issue 8, November 2024.This research presents the first time the Eastern High Arctic – Baffin Bay population of beluga whales has been modeled, using a recent abundance estimate observed from satellite imagery. This work is a first investigation into the sustainability of the current harvest levels for the entire population, which does not currently have a harvest quota ...
