Ontogenetic changes and sexual dimorphism in the cranium and mandible of the Atlantic walrus (Odobenus rosmarus rosmarus L.)

The Anatomical Record, EarlyView.
Abstract Walruses have been an important subsistence and cultural resource for humans and have been exploited for millennia across their distribution. This exploitation has contributed to severe declines in several populations and local extirpations.

Origin, evolution and biogeographic dynamics of the European rabbit (Oryctolagus cuniculus) in Southwestern Europe

The Anatomical Record, EarlyView.
Abstract The Pleistocene is a key period for understanding the evolutionary history and palaeobiogeography of the European rabbit (Oryctolagus cuniculus). The species was first documented in southeastern Iberia at the beginning of the Middle Pleistocene and appears to have rapidly spread throughout Southwestern Europe, where it was found in numerous ...

Impacts of ocean albedo alteration on Arctic sea ice restoration and Northern Hemisphere climate

Environmental Research Letters, 2015
The Arctic Ocean is expected to transition into a seasonally ice-free state by mid-century, enhancing Arctic warming and leading to substantial ecological and socio-economic challenges across the Arctic region.

Valuing Blue Carbon Changes in the Arctic Ocean

Frontiers in Marine Science, 2019
The ocean capacity to store carbon is crucial, and currently absorbs about 25% CO2 supply to the atmosphere. The ability to store carbon has an economic value, but such estimates are not common for ocean environments, and not yet estimated for the Arctic

The reversibility of sea ice loss in a state-of-the-art climate model [PDF]

, 2011
Rapid Arctic sea ice retreat has fueled speculation about the possibility of threshold (or ‘tipping point’) behavior and irreversible loss of the sea ice cover. We test sea ice reversibility within a state-of-the-art atmosphere–ocean global climate model

Let's Get to the Bottom of the Arctic! [PDF]

In this lesson students investigate benthic communities in the deep Arctic Ocean to determine the factors that influence their compositions. As a result of this activity, students will be able to identify the three realms of the Arctic Ocean and describe

Arctic Ocean fresh water changes over the past 100 years and their causes [PDF]

, 2008
Recent observations show dramatic changes of the Arctic atmosphere–ice–ocean system. Here the authors demonstrate, through the analysis of a vast collection of previously unsynthesized observational data, that over the twentieth century the central ...

Opposing consensus science through scholarly practices: The role of claims maintenance

Journal of the Association for Information Science and Technology, EarlyView.
Abstract This study examines how three US‐based communities who oppose consensus science produce and disseminate scholarly‐like artifacts: pro‐life activists, Young Earth Creationists, and Anthropogenic Climate Crisis skeptics. Prior research shows that industry‐ or church‐backed advocacy campaigns often generate claims supported by these communities ...

Arctic in Rapid Transition (ART) : science plan [PDF]

, 2010
The Arctic is undergoing rapid transformations that have brought the Arctic Ocean to the top of international political agendas. Predicting future conditions of the Arctic Ocean system requires scientific knowledge of its present status as well as a ...

Investigation of Electrolyte Salts in Non‐Flammable Triethyl Phosphate for Sodium‐Ion Batteries

Batteries &Supercaps, Volume 8, Issue 3, March 2025.
This study evaluates five sodium electrolyte salts (NaBF₄, NaClO₄, NaDFOB, NaFSI, NaPF₆) in triethyl phosphate (TEP) for sodium‐ion full‐cells, focusing on their physicochemical properties, solvation structure, and electrochemical performance. The addition of 1 wt.% vinylene carbonate (VC) improves cycling performance, with NaFSI demonstrating 88 ...
