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.

Use of glacial fronts by narwhals ( Monodon monoceros ) in West Greenland [PDF]
Biology Letters, 2016 Glacial fronts are important summer habitat for narwhals ( Monodon monoceros ); however, no studies have quantified which glacial properties attract whales. We investigated the importance of glacial habitats using telemetry data from n = 15 whales tagged in September of 1993, 1994, 2006 and ...

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'

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 ...

Tusk anomalies in narwhals (Monodon monoceros) from Greenland
Polar Research, 2022 The elongated, spiraled tusk of male narwhals (Monodon monoceros) grows continuously throughout the life of the whale and is most likely a secondary sexual trait used in male–male hierarchical competition and possibly in female mate choice.

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.

Highly Directional Sonar Beam of Narwhals (Monodon monoceros) Measured with a Vertical 16 Hydrophone Array. [PDF]
PLoS ONE, 2016 Recordings of narwhal (Monodon monoceros) echolocation signals were made using a linear 16 hydrophone array in the pack ice of Baffin Bay, West Greenland in 2013 at eleven sites.

Influence of past climate change on phylogeography and demographic history of narwhals, Monodon monoceros. [PDF]
Proc Biol Sci, 2020 The Arctic is warming at an unprecedented rate, with unknown consequences for endemic fauna. However, Earth has experienced severe climatic oscillations in the past, and understanding how species responded to them might provide insight into their resilience to near-future climatic predictions.
