On the Damage Tolerance of Diffusion Bonded Titanium–Aluminum Phase Biomimetic Composites

Rare Metals, Volume 45, Issue 2, February 2026.
ABSTRACT The biomimetic design principles of natural structures involve the strategic integration of stiff and compliant phases to synergistically enhance strength and toughness. Its evolutionary refined natural armor, characterized by a specialized microarchitecture, enables superior damage tolerance.

Understanding narwhal diving behaviour using Hidden Markov Models with dependent state distributions and long range dependence.

PLoS Computational Biology, 2019
Diving behaviour of narwhals is still largely unknown. We use Hidden Markov models (HMMs) to describe the diving behaviour of a narwhal and fit the models to a three-dimensional response vector of maximum dive depth, duration of dives and post-dive ...

Predators and scavengers: Polar bears as marine carrion providers

Oikos, Volume 2026, Issue 1, January 2026.
Scavenging is a foraging strategy widely used across the animal kingdom and apex predators provide a large amount of energy in a food web by provisioning carrion. In the harsh environmental conditions of the Arctic, apex predators such as polar bears Ursus maritimus can provide scavenging opportunities for many species. Carrion can act as a buffer when

Talking About the Weather: The Feasibility of Using Very High‐Resolution Optical Satellite Imagery to Monitor Live and Stranded Cetaceans Around the UK and UK Overseas Territories

Marine Mammal Science, Volume 42, Issue 1, January 2026.
ABSTRACT Monitoring live and stranded cetaceans can be expensive and logistically challenging, resulting in knowledge gaps. Very high‐resolution (VHR) optical satellites are considered a potential solution to addressing some of these gaps. Despite success at detecting live and stranded cetaceans, satellites have only been trialed on restricted ...

Inuit settlement in the Clyde area during “contact-exploration” times (ca. 1820-1895) [PDF]

, 2008
Dans son classique The Central Eskimo (1888), Frank Boas laisse fortement entendre qu’au moment de son périple le plus septentrional, les Inuit utilisaient très peu le littoral de la Terre de Baffin entre la baie Home au nord et le détroit d’Éclipse, qui

Estimating Narwhal (Monodon monoceros) Age Using Epigenetic Analysis of Skin

Marine Mammal Science, Volume 42, Issue 1, January 2026.
ABSTRACT Age is an important parameter to understand species life‐history characteristics. Recently, DNA methylation methods have emerged as innovative tools to estimate the age of marine mammals. Narwhal (Monodon monoceros) epigenetic age estimates were computed using beluga (Delphinapterus leucas), killer whale (Orcinus orca), bowhead (Balaena ...

Intra‐species differences in impacts of climate change: A case study of the hooded seal (Cystophora cristata)

Ecosphere, Volume 16, Issue 12, December 2025.
Abstract The Arctic is warming nearly four times faster than the global average, but the rate of change is not uniform across the region. Wide‐ranging Arctic species are exposed to variable environmental conditions across their range, but it remains unclear how different climate change regimes are affecting populations within the same species that have

A combined linkage and exome sequencing analysis for electrocardiogram parameters in the Erasmus Rucphen family study [PDF]

, 2016
Electrocardiogram (ECG) measurements play a key role in the diagnosis and prediction of cardiac arrhythmias and sudden cardiac death. ECG parameters, such as the PR, QRS, and QT intervals, are known to be heritable and genome-wide association studies of ...

Use of tusks by narwhals, Monodon monoceros, in foraging, exploratory, and play behavior

Frontiers in Marine Science
Despite the universal fascination with the tusk of the narwhal, the function of this long, spiraled tooth is still debated, primarily because few people have observed how narwhals (Monodon monoceros) use their tusks in the wild.
