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.

Back to Water: Signature of Adaptive Evolution in Cetacean Mitochondrial tRNAs [PDF]

, 2016
The mitochondrion is the power plant of the eukaryotic cell, and tRNAs are the fundamental components of its translational machinery. In the present paper, the evolution of mitochondrial tRNAs was investigated in the Cetacea, a clade of Cetartiodactyla ...

New Extralimital Record of a Narwhal (Monodon monoceros) in Europe [PDF]

On 27 April 2016, a dead narwhal (Monodon monoceros) was found on the bank of the River Scheldt, Belgium. It was the first record of this high Arctic cetacean in Belgium, and one of the most southerly records ever in Europe. Due to the decomposition of the carcass, the results of the autopsy remained inconclusive, but it is likely that the animal had ...

Vestigial Tooth Anatomy and Tusk Nomenclature for Monodon Monoceros [PDF]

The Anatomical Record, 2012
AbstractNarwhal tusks, although well described and characterized within publications, are clouded by contradictory references, which refer to them as both incisors and canines. Vestigial teeth are briefly mentioned in the scientific literature with limited descriptions and no image renderings. This study first examines narwhal maxillary osteoanatomy to
