Strange attractor of a narwhal (Monodon monoceros). [PDF]
PLoS Computational Biology, 2022 Detecting structures within the continuous diving behavior of marine animals is challenging, and no universal framework is available. We captured such diverse structures using chaos theory.

Divergent migration routes reveal contrasting energy-minimization strategies to deal with differing resource predictability [PDF]
Movement Ecology, 2023 Background Seasonal long-distance movements are a common feature in many taxa allowing animals to deal with seasonal habitats and life-history demands. Many species use different strategies to prioritize time- or energy-minimization, sometimes employing ...

Contrasting new and available reference genomes to highlight uncertainties in assemblies and areas for future improvement: an example with monodontid species [PDF]
BMC Genomics, 2023 Background Reference genomes provide a foundational framework for evolutionary investigations, ecological analysis, and conservation science, yet uncertainties in the assembly of reference genomes are difficult to assess, and by extension rarely ...

δ15N and δ13C cycles in narwhal (Monodon monoceros) embedded teeth reveal seasonal variation in ecology and/or physiology [PDF]
Royal Society Open ScienceMonitoring Arctic marine mammals in response to rapid climate change requires reliable longitudinal data. To obtain such data is challenging, but sequential measurements of stable isotopes (SI) from metabolically inert tissues like dentine allow for ...

Evidence of stereotyped contact call use in narwhal (Monodon monoceros) mother-calf communication. [PDF]
PLoS ONE, 2021 Narwhals (Monodon monoceros) are gregarious toothed whales that strictly reside in the high Arctic. They produce a broad range of signal types; however, studies of narwhal vocalizations have been mostly descriptive of the sounds available in the species'

Behavioural analysis of multi-year satellite telemetry data provides insight into narwhal (Monodon monoceros) winter prey selection in Baffin Bay. [PDF]
PLoS ONENarwhals (Monodon monoceros) are deep-diving Arctic cetaceans that migrate seasonally between summering and wintering grounds. The Baffin Bay population overwinters in southern Baffin Bay and Davis Strait, where they are known to forage on high-energy ...

Impact of Tusk Anomalies on the Long-Term Foraging Ecology of Narwhals. [PDF]
Ecol EvolWe combined stable δ13C and δ15N isotope analysis and genetic sexing to investigate whether narwhals with dental anomalies have a distinct long‐term foraging ecology. Our results showed no difference in stable isotope signature of two‐tusked male and one‐tusked female narwhals relative to normal‐tusked narwhals, indicating that an extra tusk does not ...

Vitamin C in East-Greenland traditional nutrition: a reanalysis of the Høygaard nutritional data (1936-1937) [PDF]
International Journal of Circumpolar Health, 2021 Greenlandic traditional nutrition was an almost exclusive meat dietary pattern. Høygaard et al. stayed in East-Greenland between August 1936 and August 1937.

Skull ecomorphological variation of narwhals (Monodon monoceros, Linnaeus 1758) and belugas (Delphinapterus leucas, Pallas 1776) reveals phenotype of their hybrids. [PDF]
PLoS ONE, 2022 Narwhals and belugas are toothed whales belonging to the Monodontidae. Belugas have a circumpolar Arctic and sub-Artic distribution while narwhals are restricted to the Atlantic Arctic.
