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

Shifting baselines in Antarctic ecosystems; ecophysiological response to warming in Lissarca miliaris at Signy Island, Antarctica [PDF]

, 2012
The Antarctic Peninsula has experienced a rapid increase in atmospheric temperature over the last 50 years. Whether or not marine organisms thriving in this cold stenothermal environment are able to cope with warming is of concern.

Marine Macroalgae as a Safe Healthy Food While Meeting Food Security Challenges Arising From Climate Changes

Food Safety and Health, EarlyView.
Planned harvesting and processing of marine macroalgae could meet future global food needs and mitigate fuel‐originated carbon dioxide responsible for climate change. Microalgal foods are nutritious and safe. The utilization of macroalgae would avoid environmental problems arising from the release of overgrowing macroalgae caused by heatwaves, which ...

Changes in glacier dynamics in the northern Antarctic Peninsula since 1985 [PDF]

The Cryosphere, 2018
The climatic conditions along the northern Antarctic Peninsula have shown significant changes within the last 50 years. Here we present a comprehensive analysis of temporally and spatially detailed observations of the changes in ice dynamics along ...

Antarctic Kinorhyncha: Seven new species from the Antarctic Peninsula

European Journal of Taxonomy
With only three named species, Antarctica is the continent with the least explored kinorhynch biodiversity. The present contribution provides the most comprehensive study of Antarctic kinorhynchs collected along the coast of the West Antarctic Peninsula.

New geochronological constraints on Late Pleistocene glaciation in the southern Cadí Massif, SE Pyrenees

Journal of Quaternary Science, EarlyView.
ABSTRACT The Cadí Massif (42°17′09″ N, 1°38′11″ E; 2649 m a.s.l.) in the southeastern Pyrenees preserves clear evidence of Late Pleistocene glaciation, although previous research has focused almost exclusively on its northern slope. By contrast, the southern slope has remained largely unexplored.

Unexpected Fine-Scale Population Structure in a Broadcast-Spawning Antarctic Marine Mollusc [PDF]

, 2012
Several recent empirical studies have challenged the prevailing dogma that broadcast-spawning species exhibit little or no population genetic structure by documenting genetic discontinuities associated with large-scale oceanographic features.

The Initial Opening of the Drake Passage Occurred During ca. 62‐59 Ma

Geophysical Research Letters
Although the Drake Passage has been considered a critical component of ocean circulation and climate, its initial opening age remains controversial due to the weak constraints on the paleoposition of the Antarctic Peninsula.

Competition and soil conditions limit the growth of High Arctic non‐native plants

Oikos, EarlyView.
Non‐native vascular plant species in the High Arctic are currently restricted mainly to settlements and other anthropogenically disturbed areas. The reasons for this remain unclear, but climate or dispersal do not appear to be the main limiting factors. Instead, biotic interactions combined with soil conditions may play important roles.
