Revisiting the status of the Arctic's Last Ice Area as a refuge for marine predators

open access: yesEcosphere, Volume 17, Issue 7, July 2026.
Abstract The Last Ice Area (LIA), located north of the Canadian Arctic Archipelago and Greenland, has the Arctic's oldest and thickest sea ice. The LIA is hypothesized to be a potential climate refuge for ice‐dependent top predators as Arctic sea ice continues to decline.

Data on the angular characteristics of the spiral structure of the narwhal tusk

open access: yesData in Brief, 2018
We studied morphometric features of the spiral structure of the narwhal tusk and show that angular parameters of the arcs of the cementum layer determine the pattern of the spiral structure of the tusk.

Vertical sonar beam width and scanning behavior of wild belugas (Delphinapterus leucas) in West Greenland.

open access: yesPLoS ONE, 2021
Echolocation signals of wild beluga whales (Delphinapterus leucas) were recorded in 2013 using a vertical, linear 16-hydrophone array at two locations in the pack ice of Baffin Bay, West Greenland.

Stomach temperature of narwhals (Monodon monoceros) during feeding events [PDF]

open access: yesAnimal Biotelemetry, 2014
Information on the feeding rate by free-ranging odontocetes is necessary for assessing potential conflicts with fishing activities. One way of obtaining a proxy for feeding events in homeothermic predators is to measure stomach temperature, which drops during prey ingestion.

Alphaherpesvirus infection in a free-ranging narwhal Monodon monoceros from Arctic Canada

open access: yesDiseases of Aquatic Organisms, 2023
We report the detection of an alphaherpesvirus infecting an adult female narwhal Monodon monoceros captured live during a tagging project in Tremblay Sound, Nunavut, Canada, in August 2018. The individual had 2 open wounds on the dorsum but appeared in good overall health.

Including Fitness and Health Proxies Can Alter Our Understanding of Habitat Selection

open access: yesEcology Letters, Volume 29, Issue 7, July 2026.
Habitat selection studies rarely account for fitness or health, yet our simulations show that ignoring such information can misguide management actions. Using three case studies, we demonstrate how easily health and fitness proxies can be integrated into habitat selection analyses and the added insights they provide, such as links between habitat ...

Identification of penaeid shrimp from Chilika Lake through DNA barcoding

open access: yesMitochondrial DNA. Part B. Resources, 2018
Chilika Lake is one of the prolific habitats of shrimps in India and offers tons of commercial trading every year. The genetic diversity of penaeid shrimp species in this oldest and largest brackish water lagoon is unknown so far.

Acoustic differentiation and classification of wild belugas and narwhals using echolocation clicks

open access: yesScientific Reports, 2021
Belugas (Delphinapterus leucas) and narwhals (Monodon monoceros) are highly social Arctic toothed whales with large vocal repertoires and similar acoustic profiles.

Cetacean spatial trends from 2005 to 2019 in Svalbard, Norway

open access: yesPolar Research, 2022
This study uses cetacean sighting data, acquired via a citizen science programme, to update distributions and spatial trends of whales and dolphins in waters around the Svalbard Archipelago during the period 2005–2019.
