Mapping Arctic cetaceans from space: A case study for beluga and narwhal. [PDF]
PLoS ONE, 2021 Emergence of new technologies in remote sensing give scientists a new way to detect and monitor wildlife populations. In this study we assess the ability to detect and classify two emblematic Arctic cetaceans, the narwhal (Monodon monoceros) and beluga ...

How adaptable are narwhal? A comparison of foraging patterns among the world's three narwhal populations [PDF]
Ecosphere, 2013 How organisms will fare in the face of climate change depends on their behavioral adaptability to changing conditions. Adaptability in foraging behavior will be particularly critical as food web changes are already occurring in Arctic regions. Stomach contents from narwhals (Monodon monoceros) in the Baffin Bay (BB) population have suggested that ...

Biology and Cultural Importance of the Narwhal
Annual Review of Animal BiosciencesThough narwhal have survived multiple ice ages, including 2.5 Ma and the last interglacial period with warming temperatures, Arctic climate change during the Anthropocene introduces new challenges. Despite their evolutionary connection to Arctic Pleistocene fossils, narwhal archeocete ancestors from the Pliocene ( Bohaskaia monodontoides ) and Miocene

Singulonics: narwhal-shaped wavefunctions for sub-diffraction-limited nanophotonics and imaging
ELightThe diffraction limit, rooted in the wave nature of light and formalized by the Heisenberg uncertainty principle, imposes a fundamental constraint on optical resolution and device miniaturization.

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 ...
