Intraspecific variation of cochlear morphology in bowhead and beluga whales
The Anatomical Record, Volume 309, Issue 6, Page 1514-1529, June 2026.Abstract The bony labyrinth of the petrosal bone, a distinctive feature of mammal skulls, is often identified in micro‐computed tomography imaging to infer species' physiological and ecological traits. When done as part of a comparative study, one individual specimen is normally considered representative of a species, and intraspecific variation is ...

Genetic and Ecological Divergence Between Northwest Atlantic Killer Whale Populations
Ecology and Evolution, Volume 16, Issue 5, May 2026.Killer whale (Orcinus orca) populations exhibit substantial genetic, ecological, and morphological differences across their global distribution. In this study, we use whole‐genome resequencing and compound‐specific stable isotope analysis of amino acids to show concurrent genetic and ecological differentiation in two relatively understudied killer ...

Ecology and Evolution, Volume 16, Issue 5, May 2026.We compared the traditional two‐dimensional (2D: δ13C and δ15N) isotopic niches with a three‐dimensional (3D: δ13C, δ15N, and δ34S) framework to evaluate changes in niche size and overlap. Overall, invertebrates and benthic‐associated species showed greater changes in niche size and reduced overlap using the 3D approach.

Modelling Palaeodistributions in Marine Environments: A Review
Journal of Biogeography, Volume 53, Issue 5, May 2026.ABSTRACT Aim This scoping review (ScR) synthesises the current literature on the application of Species Distribution Models (SDM) to past marine environments. We assess how these models have been used to reconstruct past environmental suitability, track biogeographical shifts and investigate long‐term ecological dynamics, while identifying key ...

Ecology and Evolution, Volume 16, Issue 4, April 2026.Southampton Island hosts two distinct benthic sub‐webs, north and south. North is deeper, phytoplankton‐driven; South is shallower, more ice‐algae driven. North benthos: bottom‐up control, four trophic levels including apex predators. South benthos: walrus top‐down control, trophic truncation to three levels.

Molecular Ecology Resources, Volume 26, Issue 3, April 2026.ABSTRACT Genetic reference databases underpin a wide range of molecular approaches used to study cetacean biodiversity, including environmental DNA (eDNA), yet their reliability depends critically on data completeness, taxonomic accuracy, and metadata quality.

NAMMCO Scientific Publications, 2002 Three ice entrapments of Monodontids have been reported in the western North Atlantic since 1993. Hunters in Disko Bay, West Greenland, discovered one in March 1994 that included about 150 narwhals (Monodon monoceros).

Aspartic acid racemization rate in narwhal (Monodon monoceros) eye lens nuclei estimated by counting of growth layers in tusks [PDF]
Polar Research, 2012 Ages of marine mammals have traditionally been estimated by counting dentinal growth layers in teeth. However, this method is difficult to use on narwhals (Monodon monoceros) because of their special tooth structures.
