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 ...

Different shape but the same topographical complexity—The lingual gross anatomy of the Saimaa (Pusa saimensis) and Baltic ringed seals (Pusa hispida botnica)

The Anatomical Record, EarlyView.
Abstract Despite the distinctly different shapes of their tongues, the tongue gross anatomy of Saimaa ringed seal closely resembled that of Baltic ringed seal. There were no differences in the extrinsic and intrinsic tongue muscles or their associated vascularization and innervation between Saimaa and Baltic ringed seals.

Snow on Antarctic sea ice

Reviews of Geophysics, 2001
Snow on Antarctic sea ice plays a complex and highly variable role in air‐sea‐ice interaction processes and the Earth's climate system. Using data collected mostly during the past 10 years, this paper reviews the following topics: snow thickness and snow type and their geographical and seasonal variations; snow grain size, density, and salinity ...

From apex to base: Uncovering spatial metabolic adaptation in Antarctic mosses

Bulletin of the Korean Chemical Society, EarlyView.
Antarctic mosses survive extreme cold, desiccation, UV exposure, and oxidative stress. We analyzed three species by separating apical, middle, and basal zones. Each zone showed distinct metabolite patterns and biological roles, revealing spatial metabolic specialization. The results suggest that whole‐plant survival depends on coordinated contributions

Multidecadal Changes in ENSO Drive a Substantial Decline in West Antarctic Sea Ice Predictability

Geophysical Research Letters
ENSO teleconnections are a key source of Antarctic sea‐ice predictability, particularly in the Antarctic Dipole (ADP) region, but whether this predictability remains stable under the recent transition toward Central Pacific (CP) El Niño is unclear. Here,

An Overview of Antarctic Sea Ice in the Community Earth System Model Version 2, Part I: Analysis of the Seasonal Cycle in the Context of Sea Ice Thermodynamics and Coupled Atmosphere‐Ocean‐Ice Processes

Journal of Advances in Modeling Earth Systems, 2021
We assess Antarctic sea ice climatology and variability in version 2 of the Community Earth System Model (CESM2) and compare it to that in the older CESM1 and (where appropriate) real‐world observations.

Post With Care: How Language Use Influences the Effectiveness of CEOs' Climate‐Related Messages on Social Media

Business Strategy and the Environment, EarlyView.
ABSTRACT Chief executive officers (CEOs) play a pivotal role in shaping public discourse on climate change through social media, yet how their language use affects the effectiveness of climate‐related posts remains unclear. Drawing on schema‐congruity theory and leader role expectations, we conceptualize certainty in language as congruent and anxiety ...

A twenty-first century structural change in Antarctica’s sea ice system

Communications Earth & Environment
From 1979 to 2016, total Antarctic sea ice extent experienced a positive trend with record winter maxima in 2012 and 2014. Record summer minima followed within the period 2017-2024, raising the possibility that the Antarctic sea ice system might be ...

Recent observations of Antarctic sea‐ice

Weather, 1999
Antarctic sea-ice is potentially one of the most sensitive global warming indicators. Some re- cent studies using coupled ocean-atmosphere general circulation models suggest that C0,- induced warming and concomitant sea-ice re- duction might be less marked than in the Arctic (Gordon and O’Farrell 1997); certainly the ...
